The maintenance cycle of vacuum pump mainly depends on its type, frequency of use, working environment and the medium it handles. The following are the maintenance cycle recommendations for several common vacuum pumps:
Oil-lubricated rotary vane vacuum pump: It is generally recommended to perform maintenance every 2-3 months.
Water ring vacuum pump: It is generally recommended to perform maintenance every six months.
Screw vacuum pump: The maintenance cycle is usually every 6,000 hours or every two years, depending on the operating conditions and environment.
Atlas vacuum pump: Generally, the first maintenance is performed after 5,000 hours of continuous operation, and then every 2,000-4,000 hours. The maintenance time can be shortened appropriately when the frequency of use is high.
Maintenance content and methods
The maintenance content of vacuum pump includes but is not limited to the following points:
Replace lubricating oil: Check and replace lubricating oil regularly to ensure smooth operation of all parts in the pump.
Cleaning the inside of the pump: Clean the scale and sediment inside the pump, and replace aging seals and consumables.
Check the seals: Make sure the seals of the pump body are intact to prevent air leakage.
Electrical system inspection: Perform a comprehensive inspection of the electrical system to ensure that the lines are firmly connected and there is no short circuit or open circuit.
Performance test: Regularly test the performance of the vacuum pump to ensure that it achieves the expected working effect.
Suggestions for extending the service life
In order to extend the service life of the vacuum pump, it is recommended to take the following measures:
Clean the dust and dirt on the surface of the pump body regularly to keep the equipment clean.
Set up a dryer to prevent corrosive gases or particulate matter from entering the pump.
Check and maintain the system pipeline to prevent leakage from causing the pump to be in a high temperature and high load state for a long time.
Regularly replace the exhaust filter element of the gas exhaust system to ensure that dry and purified air enters the pump.
