What overhaul should be carried out on the accessories of the 12HP cryogenic freezer

In the 12HP cryogenic freezer compressor is also composed of a variety of accessories, in the process of operation, should pay attention to the situation of the accessories, if you want the 12HP cryogenic freezer in a completely good operating state and long service life, then, about the compressor parts maintenance is very important
.
1.
When disassembling the components in the compressor, it is reasonable to measure the gap in each component, check and analyze the severely worn parts in detail to find out the cause, and repair or replace
them in time.
2.
Check whether there are friction marks
on the surface of the body and the surface of the spool valve.
3.
Measure the gap
between the active rotor and the driven rotor and the body.
4.
If the body or spool valve has slight wear, brushing and other marks, it can be grinded
.
5.
When the wear of the main bearing exceeds the clearance limit range of the shaft, it should be replaced
.
When replacing, it is necessary to ensure that the inner bore of the main bearing is concentric with the body, and ensure that the position of the oil groove in the casing remains unchanged and the clearance
between the main journal and the main bearing bore.
6.
When the surface roughness of the raceway of the thrust bearing is improved, the gloss is darkened or the bearing clearance exceeds the size, the bearing should be replaced, and the thickness of the inner and outer rings of the old and new bearings and the height difference between the inner and outer rings on both sides should be measured, and the end face clearance
should be adjusted accordingly.
7.
If the main journal or rotor meshing surface of the compressor is seriously worn, it can be repaired
by metal spraying method, bonding and other methods.
The metal spray coating is porous and can hold lubricating oil in the fine holes, so it has good lubrication performance and high wear resistance
