How to deal with local wear of piston of concrete pump truck?

Often hear pump friends complain: concrete pump car piston is not durable, time-consuming and laborious replacement, today we talk about, as wearing parts, pump car piston local wear how to deal with?

Concrete pump accessories concrete piston wear occurred in the local, local wear mainly assembly, installation fastening clamp or piston body does not reach the designated position, transmission axis of cylinder and piston without calibration, is the main phenomenon of piston eccentric wear, piston lip side wear serious, need to check the clamp and the piston body installation fastening, recalibrate the alignment.

Among all kinds of wear, the local wear of the lip is more serious. Other parts of the lip wear slight partial wear serious concrete pump accessories concrete piston guide part will also wear.

Local wear is commonly known as partial wear. Partial wear fault treatment is first through the identification of wear traces, if confirmed as partial wear of concrete piston; It is necessary to check the clamp and piston body installation and fastening at the same time; Ensure that the clamp and piston body are properly installed and fastened to confirm the coaxiality problem; Then after replacing the new concrete piston, loosen the six pull rods fastening the conveying cylinder; The larger displacement of the air pump 15-30 minutes later, the displacement will be reduced; Tighten 6 pull rods according to diagonal principle, and tighten them in place after several cycles; After stopping the pump, test machine pumps 200 cubic meters of concrete, recheck to confirm troubleshooting.
