The "heart Part" of Second-hand Rotary Drilling RIGS: Performance Judgment And Maintenance of The Main Pump

The main pump of a rotary drilling rig, as a core component of second-hand equipment, its performance directly affects the overall operational efficiency of the machine. The following is a popular science introduction from the key aspects of the main pump to help you understand its performance judgment and maintenance points.

1.The core position of the main pump: The main pump is the power source of the hydraulic system, just like the heart delivering power to each actuator. Its performance determines the digging force and action response speed of the drilling rig. For second-hand equipment, it is necessary to focus on checking whether the main pump has any congenital damage.

2. Key points for visual inspection: Observe whether there are any oil leakage marks or cracks on the surface of the main pump, and whether the interfaces of the connecting pipelines are intact. If there is an accumulation of oil stains, it may indicate that the seal has failed or there is internal wear.

3. Dynamic testing method: Start the drilling rig, listen for any abnormal sounds from the main pump during operation, and feel whether the pressure in the hydraulic system is stable. Abnormal noises are often caused by wear of internal parts or contamination of the oil.

4. Oil condition judgment: Regularly check the color and impurities of the hydraulic oil. If the oil turns black or contains metal debris, it indicates that there may be severe wear inside the main pump. The oil should be replaced promptly and the fault identified.

5. Key points for daily maintenance: Keep the hydraulic oil clean and replace the filter element according to the manual cycle; Avoid long-term overloading operation to reduce the wear and tear of the main pump during continuous high-pressure operation.

6. Fault Warning Signals: When the drilling rig moves slowly and the pressure drops, it may be a precursor to a decrease in the efficiency of the main pump. The machine should be shut down for inspection to prevent minor faults from escalating into serious damage.

In conclusion, the performance assessment of the main pump of a second-hand rotary drilling rig should be based on its appearance, dynamic performance and the state of the oil. Daily maintenance should focus on cleanliness and rational use. By doing these well, the service life of the main pump can be effectively prolonged and the operational efficiency of the equipment can be guaranteed.
