The actual working pressure of the pump is determined by the load size, of course, another big load variable pump repair phone, can not exceed the maximum pressure of the pump design. If the dosing pumps, flow through an external valve adjustment you will not change the output pressure of the pump, but if your load is very small, even the oil pump are back in the tank, and that the pump can not build up pressure. If the variable displacement pump, it is a great relationship, the specific flow curve depends on some pressure hour, traffic flow; pressure, the flow is small. For example, constant power variable pump. Torque variable pump service, speed, pressure. Three are mutual influence, a proxy variable pump parameters have changed, the other two have to change. Must be determined in accordance with the load torque. Then consider a variable speed pump, in order to determine the type of motor and then determine the pressure, take a look at the feasibility of the selected motor types. No word had come again, for a motor types. After determining the pressure and speed, we can determine the motor displacement.
