Screw vacuum pump with its pumping speed range, simple and compact structure, suction chamber components without friction, long life, low energy consumption, no oil pollution advantages dominate the vacuum pump sector, then these characteristics of the screw vacuum pump Realize it? The realization of these features and what factors related to it? People often say that the screw vacuum pump structural features what? Whether these structural features affect the functional characteristics of the screw vacuum pump? Screw vacuum pump structural features Drive shaft connected to the active rotor, driven by the synchronous gear driven rotor rotation, the housing has a cooling water channel to cool the rotor and exhaust port temperature, synchronous gear and bearing oil lubrication, bearings and shell Body sealed by a seal to achieve oil-free effect. Dry-type screw vacuum pump with oil-free screw compressor seal and lubrication on the structure similar to the exhaust end of the general vacuum pump mechanical seal, the inlet side of the commonly used double-lip seals. In the transmission mode, the current common is the direct motor, coupling with the rotor connection, very few with a belt or drivetrain transmission. Equal pitch screw pump due to no internal compression process, the exhaust temperature is very high, such as the cooling effect is not good, will cause the rotor and the shell deformation, affecting the suction effect. Cooling the shell is an essential part of the water cooling is the most common method, the shell body, the bearing outer side of the cooling water, cooling the shell can be cooled to achieve the purpose of the rotor. Through the above description of the structural characteristics of the screw vacuum pump, we already know that the screw vacuum pump is composed of large size bearings, seals, seals, synchronous gear sets, precision helical gears, screws, double lip seals, cooling housing and other components, The composition of the structure determines the working ability and working characteristics of the screw vacuum pump. It is believed that with the further work of many experts, the future of the screw vacuum pump is worth looking forward to. This article is copyrighted industry interconnect (Xiamen) Co., Ltd.
