Characteristics of Roots pump
There is a large pumping speed within a wide pressure range; Fast start-up, able to work immediately; Not sensitive to dust and water vapor contained in the extracted gas; The rotor does not need lubrication, and there is no oil in the pump chamber; Low vibration, good rotor dynamic balance conditions, no exhaust valve; Low driving power and minimal mechanical friction loss; Compact structure and small footprint; Low operation and maintenance costs. Therefore, Roots pumps have been widely used in the metallurgical, petrochemical, papermaking, food, and electronics industries.
Working principle of Roots pump
The working principle of Roots pump is similar to that of Roots blower. Due to the continuous rotation of the rotor, the extracted gas is drawn into the space v0 between the rotor and the pump casing through the intake port, and then discharged through the exhaust port. Due to the fully enclosed state of the v0 space after inhalation, there is no compression or expansion of gas in the pump chamber. But when the top of the rotor rotates past the edge of the exhaust port and the v0 space is connected to the exhaust side, due to the high gas pressure on the exhaust side, a portion of the gas rushes back into the v0 space, causing a sudden increase in gas pressure. When the rotor continues to rotate, gas is expelled from the pump.
The biggest advantage of Roots vacuum pump is that it has a higher pumping rate at lower inlet pressures, but it cannot be used alone and must have a front-end vacuum pump in series. The Roots vacuum pump can only start working when the pressure in the system to be pumped is reached to the allowable inlet pressure of the Roots vacuum pump by the preceding vacuum pump. And in general, Roots vacuum pumps are not allowed to operate under high pressure differentials, otherwise they will be overloaded and overheated, causing damage. Therefore, when using Roots vacuum pumps, it is necessary to choose a reasonable front-end vacuum pump and install necessary protective equipment.
