important! Difference between screw vacuum pump and claw vacuum pump

Screw pump and claw vacuum pump with the same dry-type vacuum pump, but because of their different working principles, but also caused their own structural differences, in order to obtain the lowest possible pressure, the two pumps are made of 4 , But claw pump level and level separated by a partition, and screw vacuum pump is formed by the intersection of the screw interstage separation, so there is a big difference between the two phases. important! Difference between screw vacuum pump and claw vacuum pump Difference between screw vacuum pump and claw vacuum pump First, the use of technology is different: 1, Central vacuum pump screw vacuum pump gas channel is the shortest, the transfer of gas in the same position, is conducive to the rapid discharge of gas Exhaust pump and solid particulate objects. Due to the presence of the level partition plate claw pump, the gas channel long and curved, easy to condense the gas and easy to block the channel. 2, screw pump and pump rotor and a single body, easy to carry out anti-corrosion treatment. The claw-pump level partition is almost impossible to surface-treat and the corrosion-resistant coating on the rotor surface is also easily damaged during assembly. Second, the use of reliability is different: 1 claw vacuum pump due to the level of the partition plate, the rotor and pump shaft can not be integrated, the rotor is mounted to the shaft, in order to facilitate the installation and removal, with the can not be too tight, so the operation Prone to rolling button and rotor loose phenomenon. Screw shaft and rotor vacuum pump for the whole casting after the process of molding, fully integrated, there is no assembly problem. 2, claw vacuum pump there are many gaps, and each gap is independent, as long as any one gap problems, the pump that is not working properly. Central vacuum pump screw vacuum pump only exhaust end and the gap between the rotor determines the performance, and the rotor and rotor clearance are interrelated, high reliability operation. Third, the maintenance of the different: 1, the demolition of the claw pump disassembly difficulties: due to multi-level structure, all demolition to multi-level decomposition, and rotor disassembly is the real difficulty, at the same time each disassembly, accuracy will have different degrees of reduction . Even simple cleaning must be completely dismantled and reassembled. Screw vacuum pump removal is simple: the removal of the screw pump just remove the back cover bearing can be extracted from the front end of the rotor, is extremely simple. If only for cleaning apart, just after cleaning the pump back to the body can be, without any adjustment. 2, the installation of claw pump assembly difficulties: Claw pump installation, the four rotor to control the rotor end of the eight gaps, and eight rotor rotor and rotor clearance, any gap adjustment must be rework, want to Rotor mounted to the shaft, you must also knock on the rotor, easy to damage parts. Vacuum pump screw vacuum pump assembly is simple: screw pump assembly, simply control the screw exhaust end face and the gap between the exhaust wall, and the screw concave surface clearance, simply adjust the two simple gap.
