An energy-saving hydraulic station

Abstract

The invention discloses an energy-saving hydraulic station, which includes a hydraulic system of the hydraulic station and a monitoring system of the hydraulic station. The monitoring system of the hydraulic station includes a liquid level sensor, an oil temperature sensor, an oil pressure sensor, a flow sensor, a rotational speed sensor, a proportional overflow Flow valve, proportional reversing valve, function keyboard, main microcomputer, display screen, wireless signal transmission module, etc. Compared with the traditional hydraulic station, the present invention changes the traditional instruments for measuring liquid level, oil temperature, oil pressure and flow into sensors, and adds a liquid crystal display to make the working state parameters of the hydraulic station clear at a glance; increase the motor speed measurement And the speed regulation link of the frequency converter can adjust the speed of the hydraulic pump according to the actual load of the hydraulic station, reduce the energy consumption of the motor and the reactive power loss in the oil circuit; change the manual overflow valve to a proportional overflow valve, and form a pressure closed loop with the pressure sensor In the adjustment link, the output pressure of the hydraulic station can be automatically adjusted according to the load size and demand.

Description

technical field [0001] The invention relates to the field of hydraulic stations, in particular to an energy-saving hydraulic station. Background technique [0002] At present, during the production period of the enterprise's hydraulic station, the hydraulic pump motor works 24 hours a day, which will cause energy waste on the one hand, and reduce the service life of electrical components and hydraulic components on the other hand. The capacity of the hydraulic station and the power of the motor are calculated and selected according to the load. In actual work, regardless of the load of the hydraulic station, the oil pump delivers oil 24 hours a day, and the output of the oil pump is only 25%. About 75% of the oil flows back to the oil tank through the overflow valve, and the return oil does useless work, which is converted into heat energy, causing the oil temperature in the oil tank to rise, which will damage the seals such as the rubber ring of the hydraulic system. There...
