Abstract

The invention discloses an energy consumption reduction hydraulic pump device which comprises a motor, a high-pressure oil tube, an electromagnetic relief valve, an energy storage device, a pressure transmitter, a programmable logic controller (PLC) program control cabinet and an oil tank element; and the pressure of the whole hydraulic system is controlled by the PLC program control cabinet and a non-current frequency converter. When the pressure of the system is low and the oil volume of the system needs to be supplemented, the PLC program control cabinet sends out a signal, and the motor is started without starting current with the help of the non-current frequency converter. When the pressure of the system is supplemented to be the maximum, the motor stops running under the command of the pressure transmitter. According to the device, a lot of electric energy can be saved, the oil temperature of a hydraulic station can be controlled to be the most reasonable, the sanitation and the cleanliness of a hydraulic pump station are maintained, so that hydraulic equipment achieves the purposes of saving energy and saving water.

Description

technical field [0001] The invention relates to a hydraulic pump temperature control device, in particular to a novel high-efficiency hydraulic pump device capable of reducing energy consumption. Background technique [0002] Most of the original hydraulic stations use the motor to drive the plunger pump to run 24 hours a day to deliver oil. The pressure oil is supplied to the use site through the overflow valve. When the pressure reaches the upper limit, the excess oil flows through the overflow valve at high speed. Back to the oil tank, when the pressure reaches the bottom limit, the overflow valve is closed and re-pressurized, in this way to stabilize the working pressure on site. [0003] During such a working process, the oil will work through the high-speed circulation friction of the relief valve, which will cause the oil temperature of the hydraulic station to rise, so the motor oil pump is required to suck the high-temperature hydraulic oil in the oil tank to the co...
