Details of vacuum pump maintenance

All the details of vacuum pump maintenance in this paper is organized by professional vacuum pump maintenance company, hope to help you. Vacuum pump is a kind of rotary variable volume gas delivery pump, including dry screw vacuum pump, water ring pump, reciprocating pump, slide valve pump, rotary plate pump, roots pump and diffusion pump, with a wide range of pressure within the larger pumping speed, is widely used in metallurgy, chemical industry, food, electronic coating and other industries. The quality of vacuum pump depends on its mechanical structure and the quality of oil. If the distillation of volatile organic solvents, organic solvents will be absorbed by the oil, increasing the vapor pressure, thus reducing the efficiency of pumping, if it is acidic gas, it will corrode the oil pump, if it is steam will make the oil into emulsion and pump vacuum.
Vacuum pump maintenance
Therefore, vacuum pump maintenance manufacturers remind the use of vacuum pump must pay attention to the following points of vacuum pump maintenance details:
1. An absorption device must be installed between the distillation system and the vacuum pump.
2. Before distillation, a water pump must be used to completely remove the steam of organic solvents from the system.
3. If you can take out air with a pump, try to use a pump, such as distillation substances containing volatile substances, can first use a pump pressure pumping down, and then switch to oil pump.
4. The pressure relief system must be airtight, all rubber plugs should be the right size and hole, and rubber tubes should be vacuum rubber tubes. The ground glass is coated with vacuum grease.
Suggestions on the repair and maintenance of vacuum pump:
1. Vacuum equipment should be installed in a clean and clean environment, not suitable for debris, dust, water, and areas with high temperature.
2. When the vacuum pump is installed for the first time, check whether the motor is turning forward, that is, the motor is consistent with the rotor turning inside the pump. Generally, the upper part of the motor is marked with the normal running direction of the motor.
3. The vacuum pump should be started several times intermittently before long shutdown.
4. When the vacuum pump is out of service for a long time, oil discharge should be carried out on the vacuum pump.
5. When the vacuum pump is running, the oil temperature should not be higher than 75 degrees. If the oil temperature is too high due to fault, please timely contact the vacuum pump manufacturer for maintenance.
6. If the vacuum pump has potential hazards such as inhaling impurities, dust, water and chemical substances, precision filters should be installed at the air inlet of the vacuum pump. If the impurities, dust and water are too large, a piggy bank should be installed for filtration to prevent impurities such as dust and water chemicals from entering the vacuum pump.
7. If the vacuum pump needs to operate 24 hours, it must be maintained every six months.
8. During the normal operation of the vacuum pump, the oil of the vacuum pump in the pump should not be lower than the oil mark line, and the oil mirror should be 2/3. When refueling, it is strictly forbidden to mix with different brands and models of vacuum pump oil.
9. Vacuum pump oil shall be replaced regularly, generally once every 3-6 months. If emulsification and carbonization of pump oil are found, special oil for vacuum pump shall be replaced in time.
