1. Inspection items for hydraulic pump before operation

(1) Whether the installation of the hydraulic pump is accurate and reliable, whether the screws are tightened, and whether the installation of the coupling meets the requirements;

(2) Whether the pump body is filled with oil;

(3) Whether the steering of the pump matches the inlet and outlet of the oil;

(4) Whether the safety valve of the hydraulic system is adjusted to the specified pressure value.

2. Precautions during the operation of hydraulic pumps

When starting, do not start rapidly at full speed. The prime mover switch should be pressed several times in the unloaded state of the system before continuous no-load operation can be carried out. The purpose is to eliminate the air in the pipeline as much as possible. After running 1-2 meters without any abnormal phenomena, gradually load. During the loading process, there should be no abnormal vibration, noise, or leakage. Otherwise, stop the machine immediately for inspection, analysis, and troubleshooting.

3. Maintenance of hydraulic pump after operation

If the pump is not used for a long time, the oil inside the pump should be drained, and then filled with oil with lower acidity. The exposed processing surface should be coated with rust proof oil, and each oil port should be sealed with screw plugs to prevent dirt from entering.

Hydraulic pumps have a wide range of applications and play an important role in industrial and agricultural production. There are many factors that affect the lifespan of the pump during use, in addition to the pump's own design and manufacturing factors, as well as some other factors

The selection of elements related to the use of pumps (such as couplings, oil filters, etc.) and the operation during the trial operation process are also related. This article mainly explains the common faults and solutions that occur during use, as well as the precautions during operation. As long as more inspections and maintenance are carried out in daily maintenance, and equipment defects are discovered in a timely manner, the service life of the pump can be extended.
