Wuhan Hydraulic Pump Accessories - Constant Pressure Variable Pump

Wuhan hydraulic pumpThe function of the accessory constant pressure variable pump is to ensure that the motor does not exceed its power, with high flow rate at low pressure and low flow rate at high pressure; A constant pressure pump can achieve zero flow pressure maintenance.

Constant power pumps are generally used in hydraulic systems where low pressure is required to quickly advance in the initial stage, then transition to slow approach, and finally stop and maintain pressure, such as in hydraulic presses. Here, the pressure set by the constant pressure pump is the pressure required for the system to maintain pressure. Here, the basic principle of "hydraulic system pressure is determined by the load and limited by the relief valve" should be said to be consistent. In order to better understand the pump control system, it can be considered to modify it to "The system pressure is determined by the load and limited by the constant pressure pump". For example, in the case of a press machine, the reaction force of the pressing part can be very large, and the specific amount applied is adjusted by a constant pressure pump.

Constant power pumps are mainly used in construction machinery, where there is only one engine and its power needs to be fully utilized. For hydraulic systems, large flow can be achieved at low pressure and small flow can be achieved at high pressure. This may seem similar to a constant pressure pump on the surface, but it is not. A constant power pump follows constant power when the pressure and flow rate change, while a constant pressure pump is a quantitative pump with the maximum displacement before reaching the set value, and there is no inflection point for starting constant power. After entering the constant pressure condition, in principle, the flow rate can be provided according to the system's needs while maintaining the pressure unchanged.
