important! Difference between screw vacuum pump and claw vacuum pump

March 23, 2023

Screw pump and claw vacuum pump are dry vacuum pumps, but because of their different working principles, also caused their own Structural Parts differences, in order to obtain the lowest possible pressure, the two kinds of pumps are composed of 4 stages, but the claw pump level and the liquid level are separated by a partition, and the screw vacuum pump is separated by the screw cross between the stages, So the two phases are very different. Important! The difference between screw vacuum pump and claw vacuum pump The difference between screw vacuum pump and claw vacuum pump first, the use of technology is different :1, the central vacuum pump screw vacuum pump gas channel is the shortest, the gas is transferred in the same position, which is conducive to the rapid discharge of gas and solid granular objects. Due to the existence of the horizontal partition claw pump, the gas channel is long and curved, which is easy to condense the gas and easily block the channel. 2, screw pump and pump rotor as one, easy to carry out anti-corrosion treatment. The claw pump level partition is almost impossible to surface treatment, and the corrosion resistant coating on the rotor surface is also easy to damage during assembly. Second, the use of reliability is different :1 claw vacuum pump due to the height of the diaphragm, the rotor and the pump shaft can not be integrated, the rotor is installed on the shaft, in order to facilitate installation and disassembly, can not be too tight, so it is easy to roll buttons and loose rotor phenomenon during operation. The screw shaft and rotor vacuum pump are the whole post-casting process, completely integrated, and there are no assembly problems. 2, claw vacuum pump has a lot of gaps, and each gap is independent, as long as there is a problem with any gap, indicating that the pump can not work normally. Central vacuum pump Screw vacuum pump only the gap between the exhaust end and the rotor determines its performance, and the rotor and the rotor gap are interrelated, and the operation reliability is high. 1, disassembly of the claw pump disassembly difficulties: due to the multi-level structure, all disassembly must be multi-level decomposition, and the rotor disassembly is the real difficulty, while each disassembly, the accuracy will be reduced to different degrees. Even simple cleaning must be completely disassembled and reassembled. Screw pump disassembly is simple: Remove the screw pump only need to remove the back cover bearing can be extracted from the front end of the rotor, very simple. If you only clean and separate, just put the pump back into the body after cleaning, without any adjustment.
