Safety issues should be paid attention to in the construction of putzmeister used putzmeister pump
l Keep the water tank full of clean water, and check and deal with it in time when finding the water quality is cloudy and there are many sand grains.
l Bolts of the putzmeister 42m shall be fastened, pipe joints shall be tightly sealed, and protective devices shall be complete and reliable.
l The control, high-speed handle, handwheel, control lever and cock shall be in the correct position. The hydraulic system should be normal and free of leakage.
l When the pumping system is under pressure, it shall not open any delivery pipe or hydraulic pipe. The safety valve of the hydraulic system shall not be adjusted arbitrarily, and the accumulator can only be filled with nitrogen.
l After the operation of concrete tow pumps, all the commercial concrete in the hopper and pipeline must be exported, and then the putzmeister concrete pump truck, hopper and pipes shall be cleaned. When rinsing the pipe with compressed air, no one can stand within 10 meters in front of the outlet end of the pipe, and the foam rubber and sand particles rushed out should be collected by metal net basket.
l It is strictly forbidden to flush the pipe of the placing boom with compressed air. The folding and shrinking of the placing boom should be done in order.
