introduction：Storage of lubricating oil Barrels and cans of lubricating oil should be stored in the warehouse to the extent possible，How to identify fansFAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]Cause of damage protection from weather，Packaged lubricating oil that has been used must be stored in the warehouse。The oil drum should be lying down，Both ends of the barrel must be wedged tightly，In case of rolling。If the bucket is placed straight，It is advisable to tilt the bucket slightly，To prevent rainwater from gathering on the barrel surface and covering the copper plug。Water has a bad effect on any lubricating oil。In addition, it should be checked frequently

introduction：Absorber dependent－The role of the generator group is to complete the refrigeration cycle of the chiller。It uses a binary solution as its working medium，The low-boiling component is used as a refrigerant,That is, it uses its evaporation for cooling；High boiling point components are used as absorbent,That is, it uses its absorption of refrigerant vapor to complete the working cycle。Absorption chillers are mainly composed of several heat exchangers（figure1 [The working principle of absorption refrigerator]）。The binary solution is heated in the generator，The resulting refrigerant vapor enters the condenser（The condenser），Condense into liquid，After the throttle valve depressurizes, it is sent into the evaporator for evaporation and refrigeration，Make refrigerant water(Secondary refrigerant)Temperature drop，namely

introduction：To determine exactly how overheated it is it is necessary to look at the microstructure。ifGCr15Coarse acicular martensite appears in the quenched structure of the steel，It is quenched superheated tissue。The reason may be that the quenching heating temperature is too high or the heating holding time is too long caused by comprehensive overheating；It may also be due to the severe carbide in the original tissue，Between the two bands。 Quenched crack bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，To reduce the power transmission process

introduction： 1.Machining points of shaft diameter The shaft diameter is generally cylindrical，The requirements for surface roughness are relatively high，So the surface of the shaft diameter must be finely ground，Work in grinding（Shaft diameter）The rotation direction should be consistent with the rotation direction of the shaft diameter when it is actually working。If the surface roughness of the shaft diameter after fine grinding does not meet the requirements，Grinding or polishing is required。The material of the shaft diameter should have sufficient hardness after heat treatment，For grinding and polishing。 2.Processing points of bearing hole The bearing material is usually soft，The inner cylinder is not suitable for grinding，Boring can be used、Diamond boring、Scraping or grinding process。
