Each concave curved surface on the rotary blower and the inner wall of the cylinder will form a working volume. During the rotor reversal process, the gas will be taken away from the suction port. When it moves to the exhaust port and is connected with the exhaust port, there will be a higher pressure gas backflow, which will increase the pressure in the working volume, and finally the gas will be transported to the exhaust channel. The rotor and rotor are replaced in sequence without touching each other. In order to prevent the discharged gas from being polluted by lubricating oil, the clearance between the rotors is controlled very closely, and the tight clearance is used to complete the sealing. The rotor shall also be checked for dynamic and static balance, and the straightness of shaft and rotor shall be less than 0.05mm in service.
The rotary blower is continuously rotated by the rotor, and then the extracted gas is sucked into the space between the rotor and the pump housing from the air inlet, and then discharged through the exhaust port. Because after the suction, the space between the rotor and the pump housing is completely closed, and the gas in the pump cavity will not shrink or expand. When the top of the rotor reaches the edge of the exhaust port, the space will be connected to the exhaust side, The fully enclosed condition is changed. When the gas pressure on the exhaust side is high, some of the gas will rush back into the space between the rotor and the pump casing, so that the gas pressure will increase. When the rotor continues to roll, the gas will be discharged.
Most of the oil seals of rotary blowers use fluororubber materials, because this material has the advantages of high temperature resistance, wear resistance and long service life. Because it is a constant torque load, the power saving rate is proportional to the speed drop. It has the advantages of large power and high power saving rate. It can operate continuously for 24 hours as long as the furnace wall is not bad, and the starting time is also very long. It also has the advantages of simple structure and convenient manufacturing. It is especially suitable for gas transportation and pressurization at low pressure occasions, and can also transport or aspirate under positive pressure. However, because the periodic suction, exhaust and instantaneous isochoric contraction form the pulsation of air flow velocity and pressure, large aerodynamic noise will occur, while the fan itself has small oscillation and low noise.
