The gear oil pump can not discharge liquid or the oil discharge is small: 1. The gear oil pump body does not have oil filling; 2. The oil suction height exceeds the vacuum height; 3. The oil suction pipe leaks; 4. The rotation direction is wrong; 5. The suction pipe filter The total area of ​​the oil hole is too small; 6. Blockage or other failure in the suction line; 7. The speed of the oil pump is low; 8. The resistance inside the discharge line is too large; 9. The suction pipe is not fully immersed in the liquid; 10. Due to the low liquid temperature Increase the viscosity; 11, the safety valve is open; 12, the safety valve cone surface adhesion is poor.
The elimination method of the gear oil pump: 1. Filling the oil at the vacuum pressure; 2. Increasing the oil absorption surface; 3. Checking the joints and tightening; 4. Re-wiring the motor; 5. Increasing the area of ​​the metal oil filter mesh; Check and correct the fault; 7. Check and correct with the tachometer; 8. Open the valve to reduce the discharge pressure; 9. Check and correct the position; 10. Preheat the liquid or reduce the discharge pressure; 11. Adjust the safety spring pressure; 12. Re-grind with abrasive paste.
The power required by the gear oil pump motor is too large. 1. The viscosity of the suction liquid is too large. 2. The discharge pressure is too high. 3. The resistance of the discharge line is too large. 4. The rotation part is not working properly and the friction causes high heat. 5, the oil pump suction liquid is not clean, with sand or metal powder is not worn on the tooth surface or both sides and there is a scar.
Gear oil pump elimination method: 1, preheating or reducing discharge pressure; 2, reducing discharge pressure; 3, checking and troubleshooting; 4, dismantling to check and correct it; 5, should immediately dismantle and clean and repair its defects .
The abnormal sound of the gear oil pump is caused by: 1. The liquid cannot be sucked up; 2. The parts of the oil pump are bound and improper; 3. The drive gear shaft or the driven gear shaft is not concentric; 4. The tooth surface of the gear is worn or bitten, resulting in Surface finish is reduced; 5. Interference occurs in the swivel part; 6. The bushing is worn.
Gear oil pump removal method: check, repair and replace new parts according to the above-mentioned first type of obstacle change.
Reasons for liquid leakage in the gear oil pump: 1. The packing gland is not pressed; 2. The sealing ring has been worn for a long time; 3. The sealing ring is not pressed positively; 4. The gaskets in the gaskets of each part are leaking.
The method for removing liquid leakage in the gear oil pump: 1. tighten the nut; 2. replace the new sealing ring; 3. disassemble and average the tightening nut; 4. replace the new one.
