| 1. What are the possible causes and solutions for insufficient or no oil output from the hydraulic pump? |
| • Reason: |
| Excessive resistance in the oil suction pipeline (such as clogged oil filter, low oil tank level, or air leakage in the inlet pipe). |
| Internal leakage of the pump (scratches on the oil distribution plate, poor sealing, sand holes, etc.). |
| The inclination angle of the inclined plate is too small and the displacement is insufficient. |
| Motor reversal (requires adjustment of phase sequence). |
| • Solution: |
| Clean the oil filter, add oil to the normal liquid level, and check the sealing of the pipeline. |
| Replace worn parts (such as plungers, oil distribution plates) or grind mating surfaces. |
| Adjust the variable piston to increase the inclination angle of the inclined plate. |
| 2. How to adjust if there is still traffic output at the median level? |
| Reason: Deviation, looseness, or wear of the control mechanism (such as wear of the inclined plate ear shaft). |
| Solution: Reset the controller, tighten or replace damaged parts, and check the angle holding force. |
| How to troubleshoot the high vibration and noise during pump operation? |
| • Mechanical reasons: |
| The pump and motor shaft are not concentric, the coupling is damaged, or the bolts are loose. |
| Wear of bearings or variable head bearings (dry friction or impurities in the oil during start-up). |
| • Hydraulic reasons: |
| The oil inlet pipe is too thin, the oil filter is clogged, or the oil viscosity is too high. |
| • Solution: |
| Reinstall and replace worn parts. |
| Select appropriate oil to ensure smooth fuel tank design and piping. |
| What are the causes and solutions for overheating of the pump body? |
| • Reason: |
| Mechanical friction (such as improper clearance between moving parts) or liquid friction (high-pressure oil leakage converted into thermal energy). |
| Filter blockage leads to excessive back pressure in the return oil. |
| • Solution: |
| Adjust the gap and increase the capacity of the cooler or fuel tank. |
| Clean or replace the filter. |
| How to solve the problem of oil leakage? |
| • Common oil leakage points: |
| Damaged spindle oil seal, internal leakage (high oil seal pressure), loose external pipeline or aging sealing gasket. |
| • Solution: |
| Replace the oil seal or defective shaft, check the size of the oil drain pipe, and tighten the joint. |
| What are the key points of daily maintenance? |
| • Oil management: |
| Maintain oil temperature at 25-60 ℃, cleanliness level ≥ 8, and regularly test oil quality. |
| • Regular inspection: |
| Conduct a comprehensive inspection of seals, filters, and mechanical components every 6 months. |
| After running for 3000 hours, it is necessary to check the status of the oil replenishment pump daily. |
| Before starting: Ensure that the pump is filled with oil to avoid dry friction. |
| How to adjust abnormal pressure (too high/too low)? |
| • Low pressure: Check for pipeline leaks, overflow valve faults, or cylinder block distribution plate leaks. |
| Excessive pressure: Adjust the overflow valve, check the directional valve or return oil pipeline. |
| ------ |
| precautions |
| Installation requirements: The concentricity between the pump shaft and the motor shaft should be less than 0.05mm, and the suction height should not exceed 500mm. |
| • Spare parts replacement: It is recommended to use original seals and wear-resistant components to ensure compatibility. |
