High fine centrifugal oil purifying device

Abstract

The invention relates to a high fine centrifugal oil purifying device comprising an uptake hose, a gear pump, a centrifuge, a sewage accepting tank, a motor and an oil outlet pipe, wherein, the uptake hose is connected with the input interface of the centrifuge to form an oil inlet pipeline; the output interface of the centrifuge is connected with the oil outlet pipe to form an oil outlet pipeline. The oil purifying device is provided with a PLC, a venting valve, a pressure sensor, a temperature sensor and an adjustable check valve. The PLC controls the gear pump, the check valve and the motor according to the pressure signals detected by the pressure sensor and the temperature signals detected by the temperature sensor. The invention realizes full-automatic control of the oil purifying process, ensures high oil purifying quality, is simple in operation, saves time and labor, can protect the oil pump, the motor and the centrifuge and prolongs the service life of the oil purifying device.

Description

technical field [0001] The invention relates to a purification device, in particular to a high-precision centrifugal oil purification machine, which is applied in the fields of aviation, aerospace, metallurgy, petroleum, chemical industry and the like. Background technique [0002] Petroleum-based liquids are often used to lubricate components and hydraulic systems in aircraft, natural gas transmission pump stations, road construction equipment, engines, and various machine tools. Working liquid in the system, diesel fuel in summer, etc. When impurities are mixed into the petroleum-based fluid, it will seriously affect the service life and reliability of the lubricated components and hydraulic system. [0003] At present, there is a centrifugal oil purifier that uses the principle of physical centrifugation to filter oil. The oil pump is used to drive the oil into the centrifuge. The oil enters the rotating part of the centrifuge, and the impurity particles are deposited in...

Problems solved by technology

However, all operations of this oil purifier are manual operations. First, the oil pump is manually turned on to fill the centrifuge with oil. When filling the oil, it is necessary to continuously adjust the pressure and continuously deflate through the vent plug on the top of the centrifuge. After multiple deflations, The air in the centrifuge is cleaned, and the centrifuge needs to be started manually. The centrifuge starts to start the centrifugal purification of the oil. When the oil purification effect is poor, it is impossible to reflow and adjust the flow of the oil for secondary purification. The purifier is equipped with a Pressure gauge and oil temperature gauge, but only for observation. When the pressure is too low or the oil temperature is too high, the motor or oil pump needs to be manually turned off, which is cumbersome and time-consuming.
