How to Change Oil for Water Ring Vacuum Pump

Long-term use of water-ring vacuum pump may lead to wear and tear of its parts and equipment, so it is necessary to inject lubricating oil regularly to reduce friction between parts and play a protective role on the equipment itself. Do you know how to replace lubricating oil? If you don't know, you can refer to the method of oil change summarized in the following section:

1. Remove the vacuum system of the equipment, pad one end of the chassis motor higher, and open the oil discharge plug to release oil.Industrial-Single-Stage-Water-Cycle-vacuum-Pump

2. Turn the water ring vacuum pump and cover the exhaust port, so that all the dirty oil in the cavity is discharged from the outlet.

3. Add 100-500ml new oil from the intake port, rotate continuously for more than 5-10 turns, clean the interior, and operate 3-5 times accordingly.

4. After discharging the dirty oil, install the discharging plug, flatten the pump, and add new oil from the intake port and the filling hole respectively.water-ring-vacuum-pump-for-negative-pressure-suction

Here we also want to remind you that it is very important to choose the right lubricant for equipment. Because of the strict requirements for lubricants, we should remember the following points when choosing lubricants: lubricants should have appropriate viscosity and viscous-temperature characteristics; if the equipment is inhaled by corrosive gases, lubricants are required to have good corrosion resistance and emulsification resistance, in addition, we also need to take a test. Considering its limit pressure, this is an important performance index of lubricating oil.two-stage-oil-sealed-rotary-vane-vacuum-pump
