Brief description of vacuum pump repair How to adjust the gap

The definition of the vacuum pump repair is to thoroughly repair the vacuum pump, completely solve the damaged parts or problems, and replace the conventional consumables! Since it is a thorough repair, it is not just simple disassembly, replacement of consumables, and assembly. Vacuum pumps have a lot of heart repair technology! One of the most important is the adjustment of the gap!

What is the adjustment of the gap? The clearance adjustment is for the adjustment of the distance between the rotor and the cylinder when assembling the vacuum pump cylinder, generally 0.1-0.5 filaments. The correct adjustment gap is conducive to the service life of the vacuum pump and the effective reduction of the vacuum pump blades and cylinders. Unconventional friction! In general, the vacuum degree of the vacuum pump is not high, the noise is large, the oil leakage and the smoke are all related to the gap of the vacuum pump! The gap is also one of the core technologies of the vacuum pump!

How to adjust the gap? Many customers are adjusting gaps for the end caps before vacuum pump plant technicians are not instructed! Move the end caps in and out to adjust the gap! This practice is wrong, not only can not adjust the gap, but also make the vacuum pump deflated, can not meet the standard requirements of the sealing! This will only be a vacuum pump failure. How to adjust the vacuum pump clearance must understand what is the vacuum pump clearance! Refers to the direct distance between the vacuum pump rotor and the cylinder! In other words, the clearance adjustment is to adjust the distance between the rotor and the cylinder is not to adjust the distance between the rotor and the end cap! Each vacuum pump cylinder has a positioning pin! Through the positioning pin can adjust the vacuum pump rotor up and down distance! This is the correct way to adjust vacuum pump clearance!
