The structure of rotary blower is very simple, which is composed of fan, motor, base, oil storage tank, air chamber and air filter. The working principle of the rotary fan is also relatively simple. The eccentric device installed in the rotary fan rotates in the cylinder body, and the four sliding blades installed in the rotor slot produce reciprocating motion, so as to suck in, compress and discharge the air. However, some customers may have problems, such as what is the function of the oil drip nozzle of the rotary fan? What effect does the dropping speed of the oil dropping nozzle of the rotary fan have on the operation of the rotary fan? Jinan Guli fan will give a unified reply on this issue, so that you can have a better understanding of the lubrication principle of the rotary fan and the related problems of the oil drip nozzle.
During the operation of the rotary blower, there is a small gap between the sliding plate, rotor and cylinder constituting the fan. During the high-speed operation, the machinery will generate friction and then generate heat. Therefore, when the rotary fan is running, drip necessary lubricating oil into the cylinder body from the rotary fan drip nozzle to lubricate the inside of the fan, so as to reduce friction heat and friction noise; An oil film is formed between the components to maintain the tightness of the fan. The lubrication of the rotary fan is to use the pressure difference generated during the operation of the fan to form automatic oil supply. Therefore, the rotary fan cannot operate under no-load, and must be started and operated under pressure. The lubricating oil drops into the rotating fan through the oil dropping nozzle to ensure the lubrication of the fan. Different models of rotary fans require different quantities of lubricating oil. Large rotary fans need to drip oil faster. On the contrary, small rotary fans need less lubricating oil. If the drip speed of the drip nozzle is adjusted slower, it can meet the needs.
During the operation of the rotary blower, the delivered air will contain a certain amount of oil and gas. Therefore, the air will be separated in the oil and gas separation device in the air chamber before being discharged from the pipeline, and then discharged from the pipeline, while the lubricating oil will fall back into the oil tank through the oil return pipe. Because the oil and gas will not be completely separated, the gas output by the rotary fan will contain a small amount of oil mist. Therefore, when selecting the blower, the working conditions requiring high air cleanliness should be explained in advance.
