Troubleshooting |
Causes and Elimination Methods |
|
Noise and vibration in the pump, causing resonance in pipelines and oil tanks. |
1. Connect the inlet and outlet of the pump with hoses. |
| 2. The pump should not be installed on the oil tank, the motor and pump should be installed on the base separately, and separated from the oil tank. | |
| 3. Increase the hydraulic pump and reduce the number of motor revolutions. | |
| 4. Stuff the anti-vibration material under the base of the pump and the tank. | |
| 5. Choose low noise pump and use vertical motor to immerse hydraulic pump in oil. | |
|
System resonances caused by valve springs |
1. Change the installation position of the spring. |
| 2. Change the stiffness of the spring. | |
|
3. Change the relief valve to the form of external drain. |
|
| 4. Using remote control relief valve. | |
| 5. Completely exhaust the air in the circuit. | |
| 6. Change the length, thickness, material, thickness, etc. of the pipe. | |
| 7. Increase the pipe clamp to prevent the pipe from vibrating. | |
| 8. Install a throttle valve in a certain part of the pipeline. | |
|
Vibration caused by air entering the hydraulic cylinder |
1. Drain the air. |
| 2. Apply molybdenum disulfide grease on the hydraulic cylinder piston and sealing gasket. | |
|
Noise from intense oil flow in the pipeline |
1. Thicken the pipeline to control the flow rate within the allowable range. |
| 2. Use less elbows and more elbows with small curvature. | |
| 3. Use special hydraulic hose. | |
| 4. Do not use right-angle elbow or tee in the oil flow disorder. | |
| 5. Use mufflers, accumulators, etc. | |
|
Resonant sound in fuel tank |
1. Thickened box board. |
| 2. Add rib plates on the side plates and the bottom plate. | |
| 3. Change the shape or position of the end of the oil return pipe. | |
|
Shock noise from valve reversing |
1.Reduce the control pressure of electro-hydraulic valve reversing. |
| 2. Add a throttle valve on the control line or oil return line. | |
| 3.Select components with pilot . | |
| 4. Adopt electrical control method, so that more than two valves cannot be reversed at the same time. | |
|
Poor work of the balance valve, etc., resulting in pipeline vibration and noise |
1. Install throttle valve, overflow valve, unloading valve, hydraulic control check valve at appropriate place. |
| 2.Transform into leaked form. | |
| 3. Transform the circuit. | |
| 4. Add a pipe clamp. |
