What should be paid attention to before the concrete pump is pumped?

 The use of concrete pumps has shortened the progress of the project. During the construction, many construction parties have provided pipes for concrete pumps and constructed them by controlling concrete pumps. However, in order to ensure the smooth progress of the project, the concrete pump needs to be prepared before pumping. So what should the concrete pump pay attention to before pumping? This is a problem that many construction parties are very concerned about.




  Experts pointed out that a series of preparations for concrete pumps are required before construction. For example, check the corresponding parts and follow the corresponding operating rules in the operation. So what should the concrete pump pay attention to before pumping? Specifically, you can pay attention to the following points:

1. Before pumping, when the hydraulic oil temperature is lower than 15C, the oil temperature should be increased by extending the dry running time.

2. When pumping, check the operation of the pump and the stirring device, monitor the instruments and indicators, and find that the abnormality should be stopped in time.

3. The concrete surface in the hopper should be kept above the center line of the stirring shaft.

4. Pumping concrete should be operated continuously. When forced to suspend due to supply interruption, the downtime shall not exceed 30 minutes. During the timeout period, every 5 to 10 minutes (3 to 5 minutes in winter) should be used for 2 to 3 strokes of anti-pump and positive pump movement. The material should be stirred before re-feeding. When the pump stop time is exceeded, the pipe should be drained.

5. During the operation, the grid on the hopper should not be removed, and unqualified aggregates or debris should be removed in time.

6. When the pump is found to rise to the highest value in the pumping, when the running sound changes, the pumping should be stopped immediately, and the reverse running method should be used to eliminate the pipeline blockage; if it is invalid, the pipe should be cleaned.
