Q:How to operate the concrete pump?
Start the position, adjust the handle, hand wheel, control lever, cock and so on. They should be in the correct position. The hydraulic system should be normal without leakage
Q:How to calculate the power of concrete pump motor
Concrete casting factors, concrete pump truck selection should be based on concrete engineering objects, characteristics, the requirements of the maximum transmission distance, concrete construction plan, concrete pump form and concrete conditions for comprehensive consideration
Q:How can the concrete pump pipe be cleaned?
Slowly open the compressed air intake valve, compressed air will sponge ball and concrete extrusion, if the pipeline is equipped with stop valve, should first hit in the open position, and then open the valve
Q:What are the performance characteristics of concrete pump?
A long stroke cylinder extends the service life of the cylinder and the piston
Q:What is the first generation pumping technology of concrete pump?
The machine assembly is simple and the production cost is low, but the electrical control is complex
Q:What are the fittings of concrete pump?
The commonly used electrical accessories (button switch, switch, trip circuit breaker, transformer terminals, etc.), hydraulic pipe
Q:Which height of concrete pump is the most practical?
Concrete pump truck height, according to their engineering height to determine, in reality the most widely used is 46 or 47 meters, this height is moderate, suitable for most projects in use
Q:What are the causes of pipe blockage in concrete pump?
Therefore, in the JGJ/T10-95 "concrete pumping construction technical regulations," stipulated that the sand through the 0.315mm sieve shall not be less than 15%.
Q:How to judge the concrete pipeline blockage?
Judgment of blocking position: blockage usually occurs in bends, cones, and vibrating sections. At this point, the hammer can be beaten along the pipe, the sound is boring, blocking the place; sound crisp place is normal
Q:What is the washing process of the concrete pump pipe?
Before the end of the pump, it is necessary to pump the fine stone concrete in the hopper as much as possible
