Roots Vacuum Pump maintenance

Roots vacuum pump as a common mechanical equipment in industrial production, affected by environmental factors, will inevitably wear and tear after use for a period of time, so it is very important to do a good job in all aspects of equipment maintenance, if the equipment maintenance is not good enough, there will be many kinds of operation failure.


1. Look at the wheel and axle lubrication every 90 days or so.


Second, accessories such as coupling sets and pulleys are inspected every month.


3. It is necessary to check Roots vacuum pump every day and inspect the needles in the oil gauge to keep the oil level in the correct category. Check the load and heat of the motor.


Fourth, the effectiveness of those sealing rings and the lubricant inside the bearing need to be checked every six months.


5. In addition to the above easily damaged parts, metal parts such as bearings, bearing sleeves and rotating gears are also to be maintained. They should be checked every year.


Regular addition of lubricating oil, inspection of trouble-prone areas and maintenance of Roots vacuum pump can not only maintain the normal operation of the equipment, improve its efficiency, but also reduce the failure rate, which will not hinder our proper production plan.
