Hydraulic Pump Severe Wear Analysis and Improvement
Abstract
This paper analyses the causes of severe wear of the hydraulic pump, concluding that the occurrence of severe wear may be caused by the overload of the hydraulic pump, the rust caused by water or other media, or some defects in the performance of the hydraulic pump itself, and proposes improvement measures according to the specific reasons of severe wear.
Keywords: hydraulic pump, overload, wear, rust, defects
1. Introduction
The hydraulic pump is an important component of the hydraulic system, and its wear is related to the safety and reliability of the whole system. Severe wear of the hydraulic pump not only affects the working pressure, but also causes the system to leak or even be damaged. It is of great significance to analyze the cause of the severe wear of the hydraulic pump for comprehensive understanding and correct maintenance.
2. Causes of Severe Wear of Hydraulic Pump
2.1 Overload of Hydraulic Pump
Due to improper parameters setting or system oil back pressure, when the load is large, the working pressure of the hydraulic pump will exceed the set value, and the mechanical strength of the parts will be damaged, which will cause the parts to be worn more and even severely worn.
2.2 Rust Caused by Water or Other Media
If water or other media enters the hydraulic pump, it will cause the parts to be damaged and lead to severe wear due to corrosion.
2.3 Some Defects in the Performance of the Hydraulic Pump
Poor design of the hydraulic pump, poor manufacturing accuracy and poor assembly accuracy may lead to severe wear of some parts due to the localized stress concentration of the working parts, resulting in rapid wear.
3. Improvement Measures
3.1 Suggestions to Reduce the Overload of Hydraulic Pump
●Repair and replace damaged spare parts of the hydraulic pump in time.
●Adjust the parameters of the hydraulic pump properly within the allowable range.
●Regularly inspect the performance of the hydraulic pump, and adjust and repair according to actual conditions.
3.2 Suggestions to Reduce Rust Caused by Water or Other Media
●Pay attention to the treatment of cooling water.
●Regularly clean the hydraulic oil circuit parts to prevent other media from entering.
●Install filter devices regularly to purify the environment.
3.3 Suggestions for Improving the Performance of Hydraulic Pumps
●Improve the performance of the hydraulic pump in design and manufacture.
●Check and adjust the position of the spare parts after assembly to reduce local stress concentration.
●Regularly check and replace the seal components to ensure a reliable seal.
4. Conclusion
The severe wear of hydraulic pumps is caused by overload, rust caused by water or other media, and some defects in the performance of the hydraulic pumps themselves. The reasonable design, selection, adjustment and maintenance of the hydraulic pumps can effectively reduce the wear of the pump and ensure the proper operation of the system.
