Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] like figure 2 As shown, the oil filtration system according to the present invention includes: an oil tank 10 for containing oil; an output pipeline connected to the oil tank 10 for leading out the oil in the oil tank 10, and a first output node A is provided on the output pipeline; The electronically controlled magnetic filter 30 is connected to the first output node A; the lubricating oil circuit 40 is connected to the output end of the electronically controlled magnetic filter 30 . In the present invention, an electronically controlled magnetic filter 30 is arranged on the oil circuit. Under the power-on state, the electronically controlled magnetic filter 30 has magnetism and can absorb impurities such as iron filings in the lubricating oil; When the magnetism is lost, the iron filings adsorbed on the electronically controlled magnetic filter ...

Abstract

The invention provides an oil filtration system and an air conditioning unit. The oil filtration system comprises an oil tank, an output pipeline, an electric control magnetic filter and a lubricating oil way, wherein the oil tank is used for containing oil, the output pipeline is connected with the oil tank, used for guiding the oil in the oil tank out and provided with a first output joint; the electric control magnetic filter is connected with the first output joint; the lubricating oil way is connected to the output end of the electric control magnetic filter. According to the oil filtration system, the electric control magnetic filter is arranged on the oil way, and in the power-on state, the electric control magnetic filter has magnetism and can adsorb impurities such as iron chips in lubricating oil; in the power-off state, the electric control magnetic filter losses magnetism, the iron chips adsorbed to the electric control magnetic filter fall off, in other words, the electric control magnetic filter can be reused, and therefore the frequency of filter element replacement is reduced.

Description

technical field [0001] The invention relates to the technical field of air-conditioning units, in particular to an oil filtering system and an air-conditioning unit. Background technique [0002] When the air conditioning unit is running normally, the motor shaft rotates at a speed of tens of thousands of revolutions per minute, and the high-speed running shaft and the sliding bearing need to be lubricated and cooled by lubricating oil. However, most of the impurities contained in the lubricating oil are iron filings, which are easy to scratch the bearing, and may cause the bearing to burn in severe cases. [0003] like figure 1 As shown, in order to prevent the bearing from being scratched, the air conditioning unit includes a compressor 80, a condenser 90, an evaporator 100, and an oil filtration system. The oil filtration system in the prior art includes an oil tank 10, an oil pump 20, and a high-precision oil filter 50. A permanent magnet is arranged in the oil tank 10...
