Energy-saving hydraulic station

Abstract

The invention discloses an energy-saving hydraulic station. The energy-saving hydraulic station comprises a hydraulic station hydraulic system and further comprises a hydraulic station monitoring system, wherein the hydraulic station monitoring system comprises a liquid level sensor, an oil temperature sensor, an oil pressure sensor, a flow sensor, a rotating speed sensor, a proportional overflowvalve, a proportional reversing valve, a functional keyboard, a main microcomputer, a display screen, a wireless signal emission transmitting module and the like. Compared with a traditional hydraulicstation, a traditional instrument for measuring liquid level, oil temperature, oil pressure and flow is changed into the sensor, moreover, the liquid crystal display screen is additionally arranged,so that the working state parameters of the hydraulic station are clear at a glance; motor rotation speed measurement and frequency converter speed regulation links are added so that the rotating speed of a hydraulic pump can be adjusted according to the actual load of the hydraulic station, and motor energy consumption and reactive loss in an oil path can be reduced; and a manual overflow valve is changed into a proportional overflow valve, the proportional overflow valve and a pressure sensor form a pressure closed-loop adjusting link, so that the output pressure of the hydraulic station canbe automatically adjusted along with the load size requirement.

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...
