Is your concrete pump pumping system working properly

 The pumping system of trailer concrete pump is a very important part of the whole concrete pump machine. Ensuring the safety and fault-free of the pumping system of concrete pump can effectively reduce the occurrence of construction faults.

This requires us to check and maintain it in the daily operation process.

1. The clearance between the piston and the cylinder of the trailer concrete pump shall conform to the specification.

2. The adjustment clearance between the distribution valve and the eyeglasses plate shall conform to the specifications and ensure that the pumping, return and withdrawal are powerful and should not lag behind.

3. The wear amount of the cutting ring should be within the scope specified in the instruction manual.

4, after starting, let the machine run no-load, this is very important. Observe the indicative values of each instrument, check the operation of pump and mixing device, and confirm that everything is normal before operation. In addition, adding 10 liters of clear water and 0.3 cubic meters of cement mortar to the forward hopper for pumping is also critical to lubricate the pump and pipeline.

5, parts should be complete and pipes should not leak.

6. There should be no abnormal noise in the operation of concrete pumps and oil pumps. The water quality (cooling water in rinsing tank) and oil quality should not be turbid.

7. The cooling system of the trailer concrete pump works effectively and should comply with the instructions.

8. Wet hemp bags or wet grass bags should be used to cover the pipeline under high temperature and hot sunshine, and timely watering should be adopted to cool down the pipeline. Meanwhile, thermal insulation measures should be taken in cold season.
