Precautions for compressor oil cleaning

1. It is best to use the same type of lubricant as the compressor. 2. When washing for the first time, do not connect the unit. Direct short circuit. After the cleaning is qualified, connect the unit again. 3. Make sure the fuel tank is well sealed, otherwise moisture will easily enter. Wait a minute

Hello everyone, I would like to ask you, during the maintenance of multi-stage pumps, among the different types of bearings, what kind of coordination is the inner and outer rings of the bearings, journals, and bearing seats? For example, how to equip the 32320 bearings starting with three, how to equip the deep groove ball bearings, and whether the bearing gland has preload on the outer ring of the bearing. I hope you can give me a call to explain it, thank you.

When using washing oil to clean compressor parts, I think you should pay attention to the following points:: 1. Try to avoid direct contact with the washing oil for accessories with sealing rings, such as the sealing rings between stuffing boxes, etc. 2. When using washing oil to clean the reciprocating compressor crankcase, be sure to block the oil return pipeline. Do not allow washing oil or dirty oil to enter the uninspected oil pipeline. Once it enters, it must be opened and cleaned. 3. If washing oil is used to clean key components such as compressor bearings, they must be blown clean when reassembly. Do not reinstall with washing oil.

Hello everyone, I would like to ask you, during the maintenance of multi-stage pumps, among the different types of bearings, what kind of coordination is the inner and outer rings of the bearings, journals, and bearing seats? For example, how to equip the 32320 bearings starting with three, how to equip the deep groove ball bearings, and whether the bearing gland has preload on the outer ring of the bearing. I hope you can give me a call to explain it. Thank you for your personal opinion.: The tolerance fit of the bearing and journal is: H7/js6 is an interference fit. Different types of bearings have different assembly and disassembly methods. The main reason is to consider the issue of tolerance fit. 1. Most deep groove ball bearings have a tight inner ring and a loose outer ring. When assembling, install the inner ring first, and external force must act on the inner ring. 2. The model you mentioned is 32320 bearing, which is a tapered roller bearing. It is common in transmission boxes. Most of them are used in two sets. The outer ring and inner ring of the bearing can be separated. The inner ring, rolling elements and cage are together. When installing, install the outer ring first, confirm that the outer ring is installed in place, and then install the inner ring. First I saw a post about the assembly of this type of bearing. Most people agree that this type of bearing has preloading force. In fact, this is wrong. Our on-site practice has proved that leaving a gap of 0.06~0.12mm can run longer than the assembly method with preloading force. 3. The preload force depends more on experience. Most of them are preload bearing glands. Just feel it and rotate it. Different people must have different preload forces, and there is no standard. And if through careful and careful measurement, leaving a gap of about 0.06mm, the operation effect will be better. The third floor: Shadow Man 3690! You can try it!
