Q:What are the skills of concrete pump?
) need vertical piping, along with the increase of height is the potential increase of concrete circumfluence trend, therefore should be the level of pipeline laying length between the concrete pump and vertical pipe, to ensure that there is sufficient to prevent backflow resistance of concrete
Q:If the concrete pump valve jam how to judge and deal with?
After pumping concrete, be sure to use high-pressure water to pump the body and S pipe clean. When the rinse is not available, tap the tap to remove the residue until it is thoroughly clean.
Q:How can the concrete pump pipe be cleaned?
When the concrete in the pipeline has all been emptied and the sponge ball has been fired, the air washing is completed. At this time, the compressed air intake valve should be closed, and then remove all kinds of pipe fittings.
Q:How does the concrete pump work?
The construction of automobile chassis, internal combustion engine, air compressor, water pump, hydraulic device, etc., which constitute the concrete pump truck, shall be operated in accordance with the safety instructions of the horizontal transport machinery, power plant and hydraulic machinery respectively
Q:How to calculate the power of concrete pump motor?
Second, the amount of transport is the amount of export pressure is determined,
Q:What is the second generation pumping technology of concrete pump?
Concrete pump, S pipe distribution without PLC electrical components to participate in, the failure rate is lower, more reliable control, product life has greatly improved
Q:When concrete is poured, how high can the concrete pump be put?
The car pump arm is long, traffic roads, the required pump stop position is bigger, so there are a lot of the site can not be use pump more than 60 meters (60 meters of general automobile pump, stop the pump and the leg position width of about 14 meters)
Q:Which height of concrete pump is the most practical?
The clay pump truck is modified on a truck chassis. It is mounted on the chassis with a power and motion device, a pump and a mixing device, a cloth arrangement, and other auxiliary devices
Q:What are the causes of pipe blockage in concrete pump?
In theory, plugging is most likely to occur when 3 large stones meet at the same cross section. When the section is occupied by pebbles, the circulation area is very small
Q:How to deal with the blockage in the outlet of the distributing valve of the concrete pump?
Pour the grout into the hopper, turn the pump in and out again and again, forcing the passage to open
