Note the use of concrete placing booms
Note the use of concrete placing booms
After the concrete pouring is completed, it is necessary to use mortar and clean water in the pump tubing, pumping water for each use when cleaning is necessary to use scale cleaning balls and other objects should not be used instead of, after the cleaning is completed, go to lifting weights, After hanging cloth shaft to the next working position, after installation, hanging into the counterweight, repeat the previous work.
    Boom is not free to take a long, long time to be received, promised to china manufacturer electric concrete vibrator for sale work in more than the required radius plus set a fixed support.
    Change position when the discharge port, with one sack will be exported wrap, avoid concrete fell on the ground, to another location on the material and then unlock.
    Ready for concrete placement of signal lines and radio, dual control, in the columns, walls concrete pouring, to ensure that the lamp pump stop, stop Li Ting, foreground pouring point required in advance 4S stopped, put out the lights, communication is necessary based hand carried out at night during the construction, coupled with the necessary control of concrete people flashlight, to see concrete pouring height.
    Test, with a large rope control concrete spout, and the lever arm intermediate curved split at its maximum scope week run.
    Take concrete pump tube, when taken over, it is necessary to check whether the full clean the pump tube, the interface is necessary to use a rubber gasket. After concrete pump pipe connector bolts should re-examine the case.
    Wind cable rope with cloth lever legs fixed, cable wind rope too tight, should stay out of boom force and deformation interval.
    Can not stand when the feed rod placed on the body to use when compacting frame tube legs, mounted on the ground floor.
    Mounted boom and counterweight boom intermediate requirements necessary to discharge hit 200 ~ 300mm, the foot support surface or wooden sleepers bedding, check whether the cloth club shaft vertical.
    Erection frame body boom placement, and the inspection and acceptance, 2015 wc67y-63t3200 hydraulic stainless steel bending machineto calculate the force parts of the frame body capacity, reinforcing the case of stable situation Twill member of the foundation.
    Check that the boom and tighten all bolts, whether normal hinge.
    The boom stand straight, see if you can stand straight in the case do not counterweight. (Boom normal circumstances are considered to be in the counterweight can not stand straight, as when lifting boom, common crane boom can not be hung up together with the counterweight, need to be lifted in two installation).
Concrete pump uses nine points
1. concrete pump should be fixed firmly in place after, before pumping should check whether steering pump valve seal is good, the gap should be kept within the allowable range, so that a reflux slurry is reduced to a minimum.
2. Concrete pump when the inspection found over deviation, welding electrode wear applications.
3. The existing test pump according to prescribed procedures, normal operation after delivery.
4. The concrete pump startup procedure is: Start hopper stirring blade - lubricating slurry injection hopper - Open shut-off valves - actuated concrete pumps - lubricating pump into the pipeline - the hopper filled with concrete pumping test.
5. The concrete pump drivers must undergo rigorous training, qualified before induction, the screen should be installed isolation large stones, screen size and maximum aggregate size matches the concrete pump hopper, and have someone monitor, find bulk materials , promptly removed.
6. Concrete pump pumping start, pay attention to the table and other parts of concrete hydraulic work state, generally at the outlet of the pump, prone to clogging. In case of blockage, the pump should be reversed, so that blockage concrete reflux, stirring it all and after pumping. If not effective, dismantle the pump should be shut down, clear blockage.
7. The concrete should ensure a continuous supply. If not continuous feed, galvanized sheet price with alphabet letter bending machine
may slow down the pumping speed. When disconnected, the pump can not stop working, every 4-5 minutes, should be positive and negative rotation of the pump, to prevent mixing the pipe material agglomeration or precipitation, if the pumping stop more than 45 minutes, should be clear and clean and re-pumping .
8. concrete pumping concrete, should be continued to maintain a certain amount of concrete in the hopper, to prevent the hopper into the air, causing the concrete countercurrent, blockage is formed, if there is such a problem, you need to pump reverses, the concrete hopper to return, After the normal pumping out air.
9. pumping should be changed once every 2h wash tank of water, and check the pump cylinder stroke, are subject to change, time to adjust. To reduce the cylinder walls uneven wear, the best start the long journey. Only at startup and when concrete slump small short-range pumping concrete. When transporting concrete vertically upwards, due to water hammer, can make concrete reverse flow, decrease transportation efficiency, the higher the pipes, the more obvious.stainless steel sheet bending machine bending machine mini Solution: Set between the pump and the vertical pipe section 10m above the level of the tube, in order to counteract the momentum of the impact of falling concrete; concrete pump out near the spout plus stop valve.

Concrete composition and working principle of the manual fabric machine
1. The main girder is supported by a steel pipe, tube stand, trolley, main beams and other components, the main beams mounted slewing ring seat, by the rotation of the bearing seat to do a full 360 ° rotation, the upper part of the front end of the main beam tube holder to high frequency concrete vibrator screed fix and a support fabric conveyor line, the rear end is equipped with gimbals to achieve counterweight.

(1) Good commercial concrete pumping equipment pumps pump pump compulsory quality, overload, discharging without segregation, high production efficiency, can adapt to a variety of properties of concrete pumps. Currently commodity Concrete Pumping Equipment commonly used compulsory pump, but its structure is more complex, higher cost. Compulsory twin-shaft pumps points, single horizontal shaft, single vertical shaft and planetary several forms. Since the twin-shaft pumps pump performance, high production efficiency, good adaptability, structural features outstanding reliability, is very suitable for use as commercial concrete production; single horizontal shaft pumps and single vertical pumps due to their structural characteristics and adaptation sex on the commodity Concrete Pumping Equipment applications have become less and less; planetary pump application is not currently widespread, common in imported equipment.
   Is both stirring and can be pumped concrete pump, can effectively save labor and improve efficiency. Concrete pump its high cost and high availability, access to small and medium construction projects like
(2) Goods Concrete Pumping Equipment electronic control system Currently, the domestic concrete pump electronic control system forms, mainly in the following three kinds of control mode based.
(1) Distributed computer control: this form of control early in the pump design is widely used. Core control system for programmable controllers, upper level computer only as a management report printing, functions and role of the computer is not very obvious. With the extensive application of commercial concrete, concrete pump more complex functional requirements, this form of control of application is very difficult.
 ② centralized computer control: this form of control computer control and management are centralized on a computer, the task is relatively heavy, and the production process of the report's statistical data is not synchronized and can not at any time statistical data, israel concrete batching plant manufacturer human factors by interfering metrology too much. For example: the preparation of the measurement control program, precision signal amplifier and A / D board, will affect the measurement accuracy.
 ⑧ centralized dual microprocessor control: This form that a solution to the human factors aspects of measurement. Ingredients using a dedicated control instruments, and the production control and management functions divided into two computers, without disturbing each other, production control and reporting statistics simultaneously, but also as a production management computer backup machine, provides a higher level computer network interface.

<strong>Buy concrete pump Guide</strong>
<p>In recent years, increasing state investment in infrastructure. Concrete machinery market has been rapid development, including the construction of concrete pumps booming market has played an important role in the overall experience of hydraulic cylinders made of concrete pumps from scratch, from weak to strong development process. With the market heating up, concrete pump manufacturers continue to emerge, different manufacturers, types of concrete pump more and more. "We must first of its profits", the other face of dazzling concrete pump market, the user how to identify their performance? In every cut in order to buy cheap, high-performance concrete pumps? Below this are discussed.</p>
<p>Starting from the technical parameters. used steel plate metal press bending machine Typically, concrete pump has the following main technical parameters: forms of traffic emissions, the outlet pressure, electrical power and distribution of valves. According to the new national standards, the main parameters of concrete pump from these models can be told. The following "HBTS60 - 13 - 90" concrete example, its representatives as meaning the pump. Hepatitis B - concrete pump Pinyin initials pen - concrete pump trailers S - S-shaped swing valve dispensing valve (D representation butterfly, Z said gate) 60-- theoretical maximum throughput m³ / h 13-- concrete pumps The maximum pressure outlet, MPa 90-- motor power, kW according to the outlet pressure rating on the label, into the low-pressure pump (≤5MPa), medium-pressure pump (6 - 10MPs) and high-pressure pump ("pressure 10MPa), the maximum throughput per hours, from 20 to 100m3, and concrete pumps can best achieve variable in two steps or stepless variable user should be based on the actual needs of the project, according to the height of the transmission distance, choose the outlet pressure; according to the ability of mixed feed, select the output side amount of scope; The pumping concrete aggregate according to the situation, choose Assign butterfly valve in the form of aggregate adaptability of the best, but for a larger cross-sectional area of ​​the swing, low-grade infrastructure in the concrete pump is appropriate; S-shaped swing small, the pressure loss smooth concrete flow valve pumping process, but by the limits of the total higher, suitable for medium and high-pressure pump, high-rise buildings and high-quality long-distance, high-lift transport fit between the diameter concrete butterfly valve performance and S valve, the pressure applied between the pump more.</p>
<p>A concrete pump motor power is to determine the export amount of pressure and transport, in some cases under the premise of the motor power increased pressure will reduce throughput; on the contrary, the lower the outlet pressure will increase in throughput. In order to ensure the concrete pump also has a larger throughput, but also export a certain pressure and economic strength to match the concrete pump design, they use a constant power piston; that the constant power value selection, when the outlet pressure increases The pump will automatically reduce the output displacement, the corresponding design and power values, if it is to reach the exit pressure is high, they want to convey the big goal. The only way is to increase the motor power.
Therefore, the new national standard, on the grounds that the concept of w24ypc-500 steel bar profile bending machine concrete pump capacity of the index (in the MPA cubic meters / measurement unit as high) ;, actual throughput actual concrete delivery pump outlet pressure and good product per hour, and more a large number of values, a greater ability to index motor power will be greater in order to achieve large displacement, high lift purposes. Many manufacturers in the design, but also the use of high and low voltage switch features designed to meet the different requirements of the state in economic construction, but there are greater throughput, or the same motor power, in a higher outlet pressure caused . But HBTS60 - 13 - 90, for example, when it is at maximum throughput 63m / 3h, the outlet pressure of 7.7MPa, can achieve fast pumping large displacement of low pressure, when the switch throughput thirty-seven cubic meters / hour, the largest exporter pressure 13MPa, can achieve high-pressure high-lift, long-distance transport of small displacement. Concrete pump outlet pressure reached a high level, and a large throughput in the case of sufficient power, it is impossible to achieve simultaneously. To see pump hydraulic pump parts concrete pump concrete pump configuration "heart", according to different sources there are domestic and imported hydraulic pump to the other; hydraulic gear pump according to the, structure vane pumps, piston pumps division. The same form of the hydraulic pump of different pressure levels.</p>
<p>Gear pumps low cost, adaptability, in the early days, it has been widely used, but because of less pressure, pulse resistor, typically in the low-pressure pump configuration, or only auxiliary in high-pressure hydraulic system pump concrete pump, piston swash plate and Cline points pressure to adapt its scope, is now widely used. If Jiajiang Hydraulic Machinery Factory HBTD40 - 6 - 55 low pressure concrete pump, use main pump swash plate piston Harvey V30D in Germany, the high-end component configuration, improve the quality of the machine. Imported hydraulic pump, such as Germany Rexroths A4VG, A10VG, A11VG goods and Kawasaki K3V, K5V swash plate piston pump, are world-class products. Klein made piston pumps, hydraulic power source in Guiyang representatives A7V, A8V piston pump series precision manufacturing, quality is more reliable.</p>
<p>Thus, from the hydraulic pump usage levels, ace 220v manual alloy steel bending machine you can spy a significant performance concrete delivery pump machine. Pump hydraulic valve hydraulic valve is "assistant", including sequence valves, valve, valves, unloading valves, check valves and switching valves. Chinese-made valve, unloading valve Shanghai Lixin, Beijing Howard product is good, but in valves, valves and other technical difficulty, high reliability requirements of the valve, in order to take advantage of Germany Harvey, Rexroth, Eaton, Wei Ge lice, Italy, Sri Lanka delayed (Athos), Japan, research and other world famous brands of oil as well, it will give concrete pump performance and reliable protection. If a hydraulic valve fails, it will affect the overall operation, so buy concrete pump, not only to look at the "heart", the "assistant", the basis for the best configuration. In contact with electrical components, circuit breakers, relays, etc., these actions by the logic program to control the work of the relevant departments of concrete pump electrical components. Household electrical components, although the price advantage, but the reliability and high-quality imported component life or joint venture brands are still gaps. Such as France, Germany, Siemens circuit breakers, a small Japanese Omron Relay Shinaidesi contact is similar products in the crowd.</p>
<p>To reduce the failure by the electrical contact and a plurality of causes, there are some manufacturers of concrete PLC (programmable logic controller) pump, electric system to minimize mechanical contact. PLC applications, process control to achieve non-contact, easy to automate remote control, fault detection using micro-computer preparation process, because the display for easy operation and system maintenance. In addition to the "hardware" Comprehensive analysis of concrete pump brands and services configuration options, but also analyzes the "Software" level: if the brand production history.</p>

<strong>Pump use of points</strong>
<p>1, the operator needs concrete pump truck after the professional training before induction operation.
2, the pumped concrete should meet the concrete pump can pump requirements.
3, the pump can pump pumping the main points of reference to use of concrete pumps.
4, the maximum allowed by the machine level when placing an inclination angle of 3o, larger horizontal angle of inclination would overload the steering gear fabric and endanger the stability of the machine. If the boom while moving one leg or a few of them had leg off than the earth, it is necessary to re-set legs, until all the legs can always reliable support on the ground.
5, in order to ensure the boom pumping work at its best, should do: A: The one-arm lift 45 degrees. B: The boom swivel 180 degrees. C: The two arms extend 90 degrees. D: Section 3,4,5 extension arm and horizontal position. If the last boom can be in a horizontal position, china supplier ktsa 2000 twin shaft concrete mixerit is ideal for pumping. If the position of this section boom is horizontal, then the flow rate will slow down the concrete, thereby reducing wear pipelines and end of the hose when pumping stops, only the end of the concrete will flow out of the hose . If the last boom section inclined downward state, then concrete in this part of the pipeline will accelerate the flow under its own weight, even when pumping stopped transporting concrete will continue to flow in the pipeline.
6, when the pumping is stopped for more than 5min concrete end hose must be discharged. Otherwise, since the end of the hose inside the concrete dehydration, when concrete pumping operations will be violent again discharged to splash around, as the end of the hose can be easily damaged.
7, in order to change the position of the concrete pump truck boom or need folding boom extend or retract, the first anti-pump 1-2 times and then action, so action can be placed in the pipeline transportation of concrete falling or splashing .</p>

<strong>Concrete pump buy Notes</strong>
<strong>Starting from the technical parameters</strong>
<p>Typically, a concrete pump has the following main technical parameters: transport emissions, the outlet pressure, electrical power and distribution valves form. In accordance with the new national standards, which several key parameters from the concrete model of pump can be learned. The following concrete pump "HBT60-16-110S" concrete pump as an example of their representatives significance. HB-- concrete pump pinyin abbreviation T-- towed S-- dispensing valve for the S-shaped swing 60-- maximum throughput valve, m3 / h 16 ---- concrete conveying the maximum pressure at the pump outlet, MPa 110-- motor power, kW marked according to the outlet pressure rating, into the low-pressure pump (≤5MPa), the pump (6-10MPs) and high-pressure pump (> 10MPa); according to the maximum throughput per hour, there are 20-100m3 range, and most of the laboratory heavy duty concrete mixer sale in nigeriaconcrete pump can achieve two tranches of stepless variable displacement or variable. Users should be based on the actual needs of the project, according to the height of transmission distance and choose the outlet pressure; according to the ability to feed stirring, the choice of the output side volume; according to pumping concrete aggregate situation, choose the form of the dispensing valve. S-shaped swing pipe valve pressure loss during pumping, concrete runner smoothly, but by limiting the diameter of a higher aggregate requirements, suitable for medium and high-pressure pump, suitable for high-rise buildings and concrete quality long-distance, high-lift transport; gate valve because low demand for aggregates has 'eat whole grains' with that on the application of more pressure pump, pumping height of 100 meters, 300 meters horizontal.</p>
<strong>Starting from the motor power</strong>
<p>A concrete pump motor power is to determine the amount of outlet pressure and delivery side a prerequisite under motor power in certain circumstances, increase the amount of pressure will reduce the transport; on the contrary, reducing the outlet pressure will make the delivery quantity increase. In order to ensure concrete pumps both have a larger throughput, but also a certain outlet pressure and the matching of economic power in the concrete pump's design, mostly using a constant power piston pump; that is constant power value Once selected, when the outlet pressure increases, the pump displacement volume is reduced automatically reach and power value corresponding to the design; if necessary to achieve exports of high pressure, but also want the purpose of transmission capacity. The only way is to increase the motor power. Therefore, the new national standard, the reference of the capability index concept concrete pump (in MPa · m3 / h is measured in units); that is the actual pump delivery pressure and the amount of the actual export of concrete per hour good product, the value, the more large, the greater its ability index, the greater the electrical power will, thus achieving large displacement, high lift purposes. I am in the design, functional design also features high and low voltage switch to meet the different construction requirements, economic status, can produce large amounts of transport, twin shaft js1000 concrete mixer with electric motor or to the same electrical power, resulting in a higher outlet pressure .</p>
