Concrete vehicle pump wash cleaning skills

After the construction of the concrete is complete, we must promptly clean the remaining concrete in the concrete pump pipe. How should we clean it? Let's introduce it.

After the concrete vehicle pump is completed, it is necessary to carefully clean the hopper and the pipeline system. If the residual concrete in the concrete tank is not clean, it will solidify on the cylinder wall. When the piston runs again, the piston sealing surface will directly bear the impact of the solidified concrete on the cylinder wall, which will cause the pushing piston to be locally peeled off. This kind of damage is different from the normal wear of the piston seal. The sealing surface cannot self-compensate under the effect of pressure, resulting in leakage of the slurry or suction, resulting in pumping weakness, blockage, and the like.

1. Water washing requires that the cutting ring and the eye plate (disc valve pump is the plate valve and the tie rod and the upper and lower wear-resistant pieces) have a small gap, need a lot of water, strict sealing, so that the water after washing the ball is not Before infiltration. At the end of washing, pay attention to the water in the pipeline, do not flow to the concrete casting site, so as not to affect the quality of the concrete. This method is simple, less dangerous and more commonly used.

2.Air-washing, that is, purging with compressed air, which plugs the water-soaked cleaning ball into the air inlet and wash joint, and then connects with the first straight pipe connected to the reduced diameter, and connects the end of the pipeline with safety. Cover, (the safety cover must face down). When air-contaminated concrete truck pumps are used, the pressure of the compressed air must not exceed 0.8 MPa; the air valve must be opened slowly, and the atmospheric valve can only be opened when the concrete can smoothly flow out; after the air washing is completed, the air valve should be closed immediately.

Whether washing or gas washing, valve box and hopper should be cleared. Did you get it?
