Causes of high air pressure at the exhaust side of Roots blower

In Roots blower, when the top of the rotor crosses the edge of the discharge outlet, when V0 space is connected with the discharge side, due to the high gas pressure on the discharge side, part of the gas returns to this space, making the gas pressure increase suddenly.

As the rotor continues to rotate, the gas leaves the pump. Each concave surface part of the rotor forms a working volume with the inner wall of the cylinder. During rotor rotation, when the gas moves close to the exhaust port, the gas is discharged from the suction port. Due to the high pressure connected to the exhaust port. When the pressure in the working volume suddenly increases, the gas is recirculated and then sent to the exhaust passage. The two rotors work alternately in sequence. The two rotors are not in contact with each other, and the sealing device is closely controlled by the clearance between the two rotors, so that the exhaust gas is not polluted by lubricating oil. The power saving rate is proportional to the decline rate, that is, n%=△ n%. Although it is different from the ordinary fan, the pump has a high power saving rate, but because of its high power, and as long as the furnace wall is not damaged, it can work continuously for 24 hours. Then start replacing some or all of the sound absorbing materials. The air filter, inlet and outlet valves and bypass pipes shall be inspected regularly and kept in good condition.

Roots blower

Roots blower has problems to be repaired immediately. When assembling the rotor, the parallelism deviation of the journal at both ends shall not exceed 0.02mm, and the parallelism deviation between the end face and the wall panel shall not exceed 0.05mm. The product information processing method has high precision, good performance, safe and reliable operation, long service life, simple structure design, and convenient maintenance. Including enterprise accessories, the fan economic entity is standardized, and has its own relatively complete batch development production management system, which can meet your requirements at any time.
