How to increase the outlet pressure of a gear pump oil pump? I would appreciate some guidance from the experts.
The circulation valve that regulates the inlet and outlet of the pump! Just turn it down a bit; it’s not that it’s not installed, is it? :)
Characteristics of positive displacement pumps such as gear pumps: the flow rate remains essentially constant; only when the head is too high does it decrease slightly due to leakage. And the head changes as the pipeline characteristics change. The resistance in the output pipeline is high; for example, reducing the outlet valve will increase the head pressure. In other words, the pressure will increase. Positive displacement pumps do not use the opening degree of an outlet valve to regulate flow. Bypass valves are generally used to change the stroke, speed, and so on. Why does the poster want to increase the outlet pressure? Can’t get in?
If there is nothing wrong with the pump itself, then: such pumps now come equipped with a self-acting control valve that allows oil to return to the tank; simply reduce the amount of oil returning through this valve. If there is a problem: Disassemble it for inspection, adjust the gap between the male and female rotors, or replace them.
A gear pump is a positive-displacement pump; increasing the rotational speed can raise the flow rate, while increasing the power input can increase the outlet pressure of the pump.
If the frequency can be increased, the requirements can also be met
According to the poster’s description, the system pressure should be adjusted by regulating the outlet valve.
The head of positive displacement pumps is usually related to the power
