Today's vacuum pump oil has become a class of lubricants that major companies will understand. It is through such lubricants that lubrication and protection of the vacuum pump can be completed, so it can become a lubricating oil product that is now receiving much attention. However, many companies find that the replacement of vacuum pump oil is XX important. If it cannot be replaced correctly, it may cause the lubrication of the vacuum pump oil to not be exerted, and even affect the lubrication and work of the equipment. There are certain considerations.
How often should vacuum pump oil be changed
Precautions when using vacuum pump
Vacuum Pump shaft bearing wear
The working environment is very good, usually three to six months, depending on the oil mirror in the fuel tank.
The quality of the vacuum pump depends on its mechanical structure and oil quality. It must be protected when using the vacuum pump. If distilling a more volatile organic solvent, the organic solvent will be absorbed by the oil, which increases the vapor pressure, which reduces the evacuation efficiency. If it is acid gas, it will corrode the oil pump, if it is water vapor, it will make the oil into milk The vacuum pump is damaged due to turbid liquid.
Therefore, the following points must be noted when using a vacuum pump:
1. An absorption device must be installed between the distillation system and the vacuum pump.
2. Before distillation, the vapor of organic solvent in the system must be thoroughly pumped out.
3. If you can use the water pump to pump air, try to use the water pump as much as possible. If the distilled material contains volatile substances, you can first use the water pump to reduce pressure and then use the oil pump.
4. The pressure-reducing system must be kept airtight, all rubber plugs should be of suitable size and holes, and rubber tubes should use vacuum rubber tubes. The ground glass is coated with vacuum grease.
The wear of vacuum pump transmission parts is a common problem, including bearing positions, bearing seats, bearing chambers, keyways and threads. The traditional method is mainly repair welding and brush plating spraying, but both have certain disadvantages: repair welding high temperature The generated thermal stress cannot be completely eliminated, and it is easy to cause material damage and lead to bending or fracture of components; while brush plating is limited by the thickness of the coating, it is easy to peel off, and both of the above methods use metal to repair the metal and cannot change the The "hard" cooperation relationship will still cause wear again under the combined action of various forces. Contemporary western countries mostly use polymer composite repair methods for the above problems, and the US Mikahua technology system is widely used, which has super strong adhesion, excellent compressive strength and other comprehensive properties. It can be repaired by polymer materials without disassembly and machining. There is no influence of repair welding thermal stress, and the repair thickness is not limited. At the same time, the metal material of the product does not have the concession, which can absorb the impact shock of the equipment, avoid the possibility of wear again, and greatly extend the service life of equipment components Enterprises save a lot of downtime and create huge economic value.
