Diagnosis method of common faults of double vane pump

Diagnosis method of common faults of double vane pump

Double vane pump: hydraulic equipment is a combination of mechanical, hydraulic, electrical and other devices, so the failures are also varied. A certain kind of fault phenomenon may be caused by many factors, so the analysis of hydraulic faults must be able to understand the hydraulic system schematic diagram, have a general understanding of the role of each component in the schematic diagram, and then analyze and judge according to the fault phenomenon. The causes of failure caused by many factors need to be analyzed one by one, and the main contradiction must be grasped in order to better solve and eliminate it.

Double vane pump: The flow of hydraulic fluid in components and pipelines in the hydraulic system is difficult for the outside world to understand. Therefore, it brings more difficulties to analysis and diagnosis. Therefore, people are required to have stronger analysis and judgment of faults. Ability. Find out the cause and location of the fault in many complicated relationships such as mechanical, hydraulic, and electrical, and eliminate it in a timely and accurate manner.

Double vane pump: simple fault diagnosis

The simple fault diagnosis method is a common method at present. It depends on the personal experience of maintenance personnel and uses simple instruments to understand the system's working condition according to the failures of the hydraulic system and the objective methods of asking, seeing, listening, touching and smelling. Analyze, diagnose, and determine the cause and location of the failure, as follows:

1) Ask the operator of the equipment to understand the operating status of the equipment. Including: whether the hydraulic system is working properly; whether there is abnormal phenomenon in the hydraulic pump; the time and result of the cleanness of the hydraulic oil; the cleaning and replacement of the filter element; whether the hydraulic element is adjusted before the failure; whether the sealing element is replaced; Before and after the hydraulic system has been abnormal phenomenon; in the past what happened to the system failure, is how to eliminate, etc., need to be understood one by one.

2) Look at the actual status of the hydraulic system work and observe if there are any problems with system pressure, speed, oil, leakage, vibration, etc.

3) Listen to the sound of the hydraulic system, such as: impact sound; pump noise and abnormal sound; determine whether the hydraulic system is working properly.

4) Check the temperature rise, vibration, crawl and the tightness of the joint to determine whether the moving parts work normally
