General structure of vacuum pump Vertical structure of the intake and exhaust port horizontal settings, assembly and connection of the pipeline are more convenient. However, the center of gravity of the pump is high, and the stability is poor at high speed operation, so this type of pump is mostly used for small pumps.The air inlet of horizontal pump is in the upper part and the exhaust port is in the lower part. Sometimes, in order to facilitate the installation and connection of vacuum system pipeline, the exhaust port can be connected from the horizontal direction, that is, the inlet and outlet directions are perpendicular to each other. At this time, the exhaust port can be opened from the left or right directions. In addition to one end of the exhaust pipe, the other end is blocked or connected with a bypass valve. This kind of pump has low center of gravity and good stability at high speed. General large and medium-sized pumps use this structure.The two rotor shafts of the vacuum pump are installed vertically with the horizontal plane. This structure is easy to control the assembly clearance, the rotor assembly is convenient, and the pump occupies a small area. However, the center of gravity of the pump is high and the gear assembly and disassembly is inconvenient, and the lubrication mechanism is relatively complex.CL Sereis Cone Liquid Ring Vacuum PumpRoots BlowersRoots Vacuum Pump
