Hydraulic Piston Pump Failure Analysis

When some customers use the hydraulic piston pump purchased from Elephant Hydraulic Company, they may find that there are some large and small problems with the pump. At this time, everyone will suspect that the real object of Elephant Fluid Power does not match the propaganda, because we promised the pump. Excellent quality and long life. But the editor would like to tell you that the service life of the piston pump is not only about the quality. According to relevant statistics, the failure rate of piston pumps on the market is very high, and some of the products of well-known brands have failed. Therefore, the correct use of the piston pump is an important factor that directly affects its working life. If you want to make your pump last longer, please read the following content about the use and daily maintenance of the piston pump carefully.

First of all, the piston pump should be installed on a solid foundation frame or foundation without loosening. Before starting, check whether the following places are normal: the connection part is firm; the motor rotates in the correct direction; the clutch is flexible and reliable; the pipeline connection is firm, the sealing is reliable, the bottom valve is flexible and effective; the safety valve works reliably; the power end lubricating oil bit is normal. In addition, the suction pipe, bottom valve and pump body must be filled with water before starting, the upper end of the pressure gauge buffer should be filled with oil, and the piston should be allowed to reciprocate twice to ensure no-load start when there is no obstruction. After starting, wait for the machine to operate normally, and then slowly increase the load. During use, test the sand content of the mud from time to time. If the sand content of the mud exceeds 10%, stop immediately. If you buy a pump with multiple gears, try not to change gears during operation, stop the pump and then change gears. If there is abnormal noise or abnormal water volume and pressure during operation, or there is obvious high temperature, the pump should be stopped for inspection. Under normal circumstances, the pump should be stopped at no-load. When the pump is stopped for a long time, all the water holes should be opened, the cylinder head should be loosened, and the drain rod of the bottom valve should be lifted to discharge all the mud and sand in the pump body and pipeline. When using piston pump grouting, after the grouting is completed, the pump and the grouting pipeline should be cleaned with water using the quick stop.
