In the hydraulic system of the excavator, the pilot pump plays a vital role. This article will focus onExcavator pilot pumpAnalyze the definition, functions, frequently asked questions and market trends, and provide you with structured data based on the hot topics on the entire network in the past 10 days.
1. Definition and function of excavator pilot pump
The excavator pilot pump is a key component in the hydraulic system. It is mainly responsible for providing pilot pressure oil to the control valve, thereby achieving precise control of the flow and direction of the main pump. Its main functions include:
| Function | Description |
|---|---|
| Provide pilot pressure | The control valve is driven by a small flow of high-pressure oil to reduce operating force. |
| Energy saving and efficient | Reduce the main pump load and improve the response speed of the hydraulic system. |
| Stability guarantee | Make sure the excavator moves smoothly and avoid hydraulic shock. |
2. Common failures and solutions of pilot pumps
According to industry discussions and maintenance cases in the past 10 days, common problems with pilot pumps mainly focus on the following aspects:
| Fault phenomenon | Possible reasons | solution |
|---|---|---|
| Not enough pressure | Pump body wear and oil contamination | Replace the pump body or filter element and clean the hydraulic oil circuit. |
| Abnormal noise | Bearing damage, air intake | Check sealing and replace bearings. |
| Temperature too high | Improper oil viscosity and excessive load | Replace the appropriate oil and adjust the working load. |
