Safe use of the hottest concrete pump

  • Detail

Safe use of concrete pump

(1) the particle size of sand and gravel, cement grade and mix proportion shall meet the requirements of mechanical performance of the pump according to the factory instructions

(2) the parking brake and locking brake of the pumping equipment should be used at the same time, the tires should be wedged tightly, the water supply should be normal, the water tank should be full of clean water, there should be no sundries in the hopper, and the lubrication points should be lubricated normally

(3) the bolts of all parts of the pumping equipment should be fastened, the pipe joints should be fastened and sealed, and the protective devices should be complete and reliable

(4) operate the start of each part, and adjust the handle, handwheel, control rod, cock, etc. in the correct position. The hydraulic system should be normal without leakage

(5) prepare cleaning tubes, cleaning supplies and other related devices from many OEM manufacturers. Before operation, the pipes must be lubricated with cement mortar prepared as required. Irrelevant personnel must leave the pipeline

(6) the outriggers should be fully extended and firmly supported. The test error of the electronic universal testing machine should not start the boom before it is fixed. The boom can only rotate after raising the support. The boom should be extended in sequence. It is strictly forbidden to use the boom to lift or drag objects

(7) when the boom is in the full extension state, it is strictly prohibited to move the body. When it is necessary to move during the operation, the upper boom should be folded and fixed, and the moving speed should not exceed 10km/h. The distribution pipe with the diameter exceeding the specified diameter shall not be used for the distribution rod, and the installed wheel pipe shall be tied with an anti falling safety rope

(8) various instruments and indicator lights should be monitored at any time. If abnormal, they should be adjusted or handled in time. If the conveying pipe is blocked, reverse the operation to return the concrete to the hopper. If necessary, remove the pipe to eliminate the blockage

(9) when the pumping system is under pressure, do not open any transmission pipeline and hydraulic pipeline. The safety valve of the hydraulic system shall not be adjusted arbitrarily. The accumulator can only be filled with ammonia

(10) after the operation, all the concrete in the hopper and pipeline must be output, and then the pump, material and pipeline must be cleaned. When washing the pipeline with compressed air, no one is allowed to stand within 10m in front of the outlet end of the pipeline, and the washed foam rubber and sand and gravel particles should be collected with a metal basket

(11) no 7 Change the electrical box on the base of the experimental machine and flush the distribution rod piping with compressed air. The elastic modulus of cloth bending and compression is the folding shrinkage of the material rod, which must be carried out in sequence

(12) the operating switches, adjusting handles, hand wheels, control valves, cocks, etc. of all parts should be reset. Unloading of hydraulic system
