Fault Repair and Prevention of High-pressure Pipe Dredging Machine

Although the high-pressure pipe dredging machine is efficient and practical, it is inevitable to encounter failures after long-term use. One of the common failures is insufficient pressure in the high-pressure pump. This may be due to the wear of the seals inside the pump, resulting in pressure leakage. During maintenance, the seals need to be replaced, and at the same time, the internal parts of the pump should be inspected. If there is any damage, they should be replaced promptly. To prevent this failure, the pump should be regularly maintained, the sealing performance should be checked, and over-use should be avoided to prevent wear.

Nozzle blockage is also a common problem. When there are many impurities in the water, it is easy to cause blockage. The solution is to disassemble the nozzle and clean the obstructions. To prevent nozzle blockage, a filter can be installed at the water source to filter the impurities in the water, and the nozzle should be flushed after each use.

In addition, water leakage at the pipeline connection parts cannot be ignored. This is mostly due to loose interfaces or aging of the sealing washers. During maintenance, the interfaces need to be tightened or the washers replaced. In daily use, the connection parts should be regularly inspected, loose situations should be discovered and dealt with on time, and the sealing washers should be replaced according to the service cycle to ensure the normal operation of the equipment and extend its service life.
