Woodworking engraving machine vacuum pump commissioning notes?
In the operation of water ring vacuum pump, the bearing temperature shall not exceed the ambient temperature 35C, and the maximum temperature shall not exceed 80C.
Start the motor, when the water ring vacuum pump after normal operation, open the outlet pressure gauge and import vacuum pump, as it shows the appropriate pressure, gradually open the gate valve, and check the motor load.
Point motor to see if the motor is correct.
1) add bearings, lubrication, oil or grease to the bearings periodically.2) the use of water ring vacuum pump, screw water diversion plug under vacuum pump, filling water.
