It should be noted that the temperature control valve (18) is an original facility of the air compressor, in this embodiment, the function of the temperature control valve (18) does not exceed the original function, specifically, the temperature control valve (18) is opened when the temperature is higher than the highest temperature in the set temperature range, high-temperature lubricating oil flows into the cooler from the oil-gas separator (15) through the temperature control valve (18) from the lubricating oil inlet pipeline (7), flows out from the lubricating oil outlet pipeline (8), and enters the host through the air compressor host oil inlet pipe (16), so as to achieve the lubricating oil cooling effect. When the temperature of the lubricating oil is lower than the lowest temperature in the set temperature range, the temperature control valve (18) is closed, so that the lubricating oil does not flow into the cooler through the lubricating oil inlet pipeline (7), but flows into the air compressor main engine (14) from the air compressor main engine oil inlet pipe (16) through the temperature control valve (18), and the temperature control valve (18) plays a role in stabilizing the oil temperature.
The oil-gas separator (15) is communicated with the first oil cooler (2) through a lubricating oil inlet pipeline (7), the second oil cooler (3) through a lubricating oil outlet pipeline (8) and the gas cooler (1) through a compressed air conveying pipeline (9) through a temperature control valve (18); a lubricating oil inlet regulating valve (4) is arranged between the lubricating oil inlet pipeline (7) and the first oil cooler (2).
