Oil returning and dripping system of rotary fan

Abstract

The invention relates to an oil returning and dripping system of a rotary fan, and relates to the technical field of blast equipment. The oil returning and dripping system comprises a base, a main machine, an oil tank and an oil returning pipe, wherein one end of the oil returning pipe is communicated with the oil tank through a filter element, the other end of the oil returning pipe is communicated with the main machine through a valve, the filter element comprises a supporting frame and a filter screen, and the filter screen comprises a barrel part and an end part; the end part is arranged at one end of the barrel part in the length direction, one end, far away from the end part, of the barrel part is fixedly connected with the supporting frame, a filter cavity is formed between the supporting frame and the filter screen, the supporting frame is communicated with the interior of the filter cavity and fixedly connected to the oil tank, the filter screen penetrates through the oil tank, and the oil return pipe is communicated with one end, far away from the filter screen, of the supporting frame. According to the oil returning and dripping system of the rotary fan, lubricating oil can be filtered, so that the probability that the oil return pipe and a valve are blocked is reduced; and meanwhile, the speed of the lubricating oil flowing into a main machine can be regulated and controlled, so that the abrasion speed of the inner wall of the main machine can be reduced, the lubrication and heat dissipation efficiency of the inner wall of the main machine is improved, and meanwhile consumption of the lubricating oil is reduced.

Description

technical field [0001] The present application relates to the field of experimental equipment, in particular to a rotary blower return oil drop system. Background technique [0002] The rotary blower is a kind of fan, which realizes aeration by compressing air, so it is also called aeration blower. The blower operates eccentrically by the biased rotor in the cylinder, and makes the volume change between the vanes in the rotor slot suck, compress and spit out air. [0003] The current rotary blower generally includes a base, an oil tank is fixedly connected to the base, and lubricating oil is stored in the oil tank. The main engine and the oil-air separator are fixedly connected to the base, the exhaust end of the main engine is connected with the oil tank through the oil-air separator, and the oil tank is connected to the air intake end of the main engine. During the working process, the air pressure at the exhaust end of the main engine is greater than the atmospheric pre...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when the lubricating oil in the oil tank flows into the main engine, the flow rate is prone to be unstable. If the flow rate of the lubricating oil is too large, the consumption of the lubricating oil will be accelerated; If the flow rate is too small, the lubrication and cooling effect of the inner wall of the main engine will be reduced
