FAQ

 

1. What are the main application areas of hydraulic gear pump?
Hydraulic gear pump is widely used in construction machinery, agricultural machinery, ships, industrial equipment and other fields, often used in hydraulic system power transmission and liquid transport.

2. How to choose the right hydraulic gear pump?
Consider the following factors when choosing:
- Flow requirements: Determine the flow of the pump according to the system requirements.
- Pressure rating: Ensure that the rated pressure of the pump meets the system requirements.
- Medium type: Select the appropriate material and sealing method according to the conveying liquid.
- Working environment : Consider temperature, humidity and other environmental factors.

3. What are the common faults and solutions of hydraulic gear pump?
- Insufficient flow: Check whether the suction line is blocked or leaked to ensure sufficient oil.
- Excessive noise: Check gear wear or air in the oil, and replace gear or exhaust if necessary.
- Unstable pressure: Check the system for leaks or internal wear of the pump, and repair or replace it in time.

4. What do you need to pay attention to the maintenance of hydraulic gear pump?
- Check the cleanliness of the oil regularly to avoid impurities entering the pump.
- Replace seals regularly to prevent leaks.
- Check gear and bearing wear, timely replacement.
- Keep the oil within the proper operating temperature range.

5. How long is the life of hydraulic gear pump?
Life depends on working conditions, maintenance and frequency of use. Under normal use and maintenance, the life of the hydraulic gear pump can usually reach thousands of hours.

6. Can the hydraulic gear pump be used in reverse?
Reversal is generally not recommended because the pump design and seal structure are designed for one-way rotation, and reversal can cause seal failure or pump damage.

7. What are the installation precautions of hydraulic gear pump?
- Make sure the inlet and outlet of the pump are properly connected.
- Avoid excessive external force acting on the pump body during installation.
- Ensure good alignment of pump and drive shaft to avoid vibration and noise.

8. What are the material choices of hydraulic gear pump?
Common materials include cast iron, aluminum alloy, stainless steel, etc., the choice should be determined according to the working medium and environmental conditions.

9. How to solve the noise problem of hydraulic gear pump?
- Check whether there is air in the oil and exhaust in time.
- Check gears and bearings for wear and replace them if necessary.
- Ensure that the oil viscosity is appropriate to avoid too high or too low.

10. What checks do you need to do before starting the hydraulic gear pump?
- Check whether the oil is sufficient and whether the oil circuit is smooth.
- Check that the rotation direction of the pump is correct.
- Check whether the connection parts are tight to avoid leakage.

11. How to guarantee the after-sales service of hydraulic gear pump?
We provide comprehensive after-sales service, including technical support, maintenance and spare parts supply, to ensure that customers have no worries during use.
