Characteristics of Three-leaf Roots Blower

　　Three-leaf Roots blowerIt is a double-impeller synchronous compressor. Each three-lobe rotor is supported by two bearings. A pair of synchronous gears are used to keep the relative position of the two rotors constant. It is a positive displacement blower with forced gas transmission. Features. As the rotating machinery of the three-blade Roots blower, it has relatively stable working characteristics. There are small gaps between the rotor and the rotor, the rotor and the pump body, the rotor and the side cover of the three-leaf Roots blower. There is no friction in the working cavity, no contact and wear parts. The three-leaf Roots blower is economical and durable, does not require lubrication, and has a long service life., Good power balance. There are six suction and exhaust processes in one cycle, so the volumetric efficiency is high. The structure of the three-leaf Roots blower is simple, easy to use and maintain, no internal lubrication, and no oil medium. The bracket of the pump adopts a reliable anti-backlash structure, the rotating part is finely balanced, and high-precision helical gears are used. Therefore, the pump runs smoothly, has low noise, is more reliable, and can run for a long time under high pressure difference. The dynamic sealing part adopts imported patented technology and imported oil seal, and the control shaft seal runout is less than 0.01mm.

What are the characteristics of the three-leaf Roots blower? Let's take a brief look at it.

Due to the three-blade rotor structure and reasonable inlet and outlet structure in the casing, the fan has low vibration and low noise. The impeller shaft and the impeller shaft are integrated structure, the impeller has no wear, the fan performance is constant, and it can run continuously for a long time. The fan has high volume utilization rate, high volume efficiency, compact structure and flexible installation mode. Various machines can meet the needs of different users for different purposes.

　　Three-leaf Roots blowerHow to use the operation? Below we all together to briefly understand.

1. Comprehensively check all parts of the fan, check whether the parts are complete, the connection tightness of bolts and nuts, the installation quality of fasteners and positioning pins, the installation quality of intake and exhaust pipes and valves, etc. 2. In order to ensure the safe operation of the blower, it is not allowed to carry additional loads such as pipes, valves, frames, etc. 3. Check the alignment quality of the blower and motor. 4. Check whether all bases of the device are padded and whether the anchor bolts are fastened. 5. Inject the specified brand of mechanical oil into the oil tank to the oil level line. The lubricating oil brand is N220 medium load working gear oil. 6. Check whether the motor steering meets the pointing requirements. 7. Belt cover (protective cover) should be installed at the pulley (coupling) to ensure the safety of operation and use. 8. Open all the inlet and outlet valves of the fan and rotate the fan rotor, which should be flexible without impact and friction. After everything is normal, the blower can be started for trial operation. 9. Blower empty load test run.

　　Three-leaf Roots blowerThe two impellers rotate in reverse. Because the gap between the impeller and the impeller, between the impeller and the casing, and between the impeller and the wall plate is extremely small, the air inlet is in a vacuum state, and the air enters the air intake under the action of atmospheric pressure. cavity. Then, the two blades, the wall panel and the shell form a sealed cavity. During the rotation process, the air in the intake cavity is continuously brought to the exhaust cavity by the sealed cavity formed by the two blades, and because the impeller in the exhaust cavity Mesh with each other, the air between the two blades is squeezed out, and the air is continuously transported from the air inlet to the air outlet. This is the entire working process of the Roots blower.
