| Three Leaf Roots Blower The Roots blower is a positive displacement fan, and the air volume delivered is proportional to the number of revolutions. The three-blade impeller is sucked and exhausted by two impellers for three times each time it rotates. Compared with the two-leaf type, the gas pulsation is small, the vibration is also small, and the noise is low. The impeller on the two shafts of the fan and the inner hole surface of the elliptical shell, the end face of the impeller and the front and rear cover of the fan, and between the fan impeller always maintain a small gap. Driven by the synchronous gear, the wind flows from the fan inlet along the inner wall of the shell Delivery to the discharge side. The internal cavity of the fan does not need lubricating oil, has a simple structure, stable operation, stable performance, adapts to a variety of purposes, and has been used in a wide range of fields. |

When the rotor of the rotary fan eccentrically installed in the cylinder body rotates, the 4 blades in the rotor slot will reciprocate, and the air will be sucked in, compressed and discharged to form the fan, the blades and the rotor, and the cylinder body rubs against each other to generate heat. Therefore, when the fan is running, the necessary lubricating oil is dropped into the cylinder body from the drip nozzle to lubricate the surface to reduce frictional heat and frictional noise; and an oil film is formed between the components to maintain the airtightness of the fan. The lubrication system is a circulating device that automatically supplies engine oil formed by the pressure difference generated when the fan is working. |
