1. To measure the ultimate pressure of the rotary vane vacuum pump manufacturer, please use a compression vacuum gauge to measure the ultimate pressure of the rotary vane vacuum pump directly at the suction port of the pump. After using the pump for the first time, after using it for a long time, and after using new oil, close the suction port for at least 1 hour, after the rotary vane vacuum pump reaches the working temperature and the pump, degas the oil completely, and measure the ultimate pressure.

　　2. Rotary vane vacuum pump manufacturers For the electrical wiring of the rotary vane vacuum pump, the wires of the water ring vacuum pump rotary vane vacuum pump must be performed by professional electricians, and appropriate motor overload protection should be used. After the three-phase asynchronous motor of the rotary vane vacuum pump is wired, the rotation of the motor must be checked.

　　3. For the system connection of the rotary vane vacuum pump, the suction rotary vane vacuum pump tube of the rotary vane vacuum pump should be cut to the shortest possible size above the size of the suction port, and the threaded joint should be vacuum sealed.

　　Rotary vane vacuum pump manufacturers found that the rotary vane vacuum pump is a positive displacement pump, which operates continuously in the pump chamber through a rotary type, inhales the gas for compression, and finally discharges it from the exhaust port. The pump is mainly composed of a stator, a rotor, a rotating plate, etc., and the rotor is eccentrically assembled in the stator chamber. There are two rotors in the rotor slot, and a rotor spring is placed between the rotors. The supply and exhaust ports of the stator are separated into two parts by the rotor and the seat.
