Fault diagnosis and troubleshooting of Parker oil pump

2025-02-21

The primary tasks for diagnosing and troubleshooting faults in Parker oil pumps include:

(1) Determine the nature and severity of the problem. Based on the on-site situation, determine whether there is a problem, what kind of problem it is (pressure, speed, movement or other), and the severity of the problem (normal, minor, general or severe).

(2) Find the faulty component and its location. Based on symptoms and relevant information, identify the problem points of Parker hydraulic motor components in order to further eliminate the problem. The first thing to clarify here is where the problem lies.

(3) Further investigate the initial causes of the problem, such as hydraulic oil contamination, low reliability of hydraulic components in Parker vane pump accessories, and environmental factors that do not meet requirements. The first thing to clarify here is the external cause of the problem.

(4) Mechanism analysis. Deepen the analysis and discussion of the causal chain of the problem, clarify the origin and development of the problem.

(5) Clean up the problem. The first priority is to eliminate various factors that cause problems and restore the system to normal.
