How to increase the outlet pressure of gear pump

The methods to increase the outlet pressure of gear pumps include:

1. Increase the rotational speed

-Method: Increase the motor speed.

-* * Caution * *: High rotational speed may cause cavitation or wear.

2. Increase gear width

-Method: Use wider gears.

-Attention: Widening the gear will increase the size and weight of the pump.

3. Reduce the gap

-Method: Reduce the gap between the gear and the pump body, as well as between the gear end face and the side plate.

-Attention: A small gap may increase friction and wear.

4. Increase liquid viscosity

-* * Method * *: Use a higher viscosity liquid.

-Attention: High viscosity liquids may increase energy consumption and temperature rise.

5. Optimize gear design

-* * Method * *: Improve gear tooth profile and modulus.

-* * Attention * *: It is necessary to ensure that the design meets the requirements of strength and durability.

6. Increase the number of pump stages

-Method: Use multi-stage gear pumps in series.

-Attention: Multi stage pumps have complex structures and high costs.

7. Use a high-pressure pump

-Method: Choose a specially designed high-pressure gear pump.

-* * Attention * *: High pressure pumps have a high cost and need to be selected according to demand.

8. Optimize system design

-* * Method * *: Reduce pipeline resistance and pressure loss.

-* * Attention * *: Reasonably design the layout of pipelines and valves.

9. Regular maintenance

-* * Method * *: Regularly inspect and replace worn parts.

-Attention: Failure to maintain in a timely manner can reduce the performance and lifespan of the pump.

10. Control temperature

-* * Method * *: Keep the liquid temperature stable.

-Attention: Excessive temperature can reduce the viscosity of the liquid and affect the performance of the pump.

summary

To increase the outlet pressure of the gear pump, multiple methods need to be considered comprehensively, and appropriate solutions should be selected according to specific needs, while paying attention to the potential negative impact on the gear pump.
