Operating instructions for 2x rotary vane vacuum pump:
1. precautions for operation of rotary vane vacuum pump:
( 1 ) start intermittently for 1 to 2 times, and observe whether there is any abnormal noise or special vibration during operation. only when there is no problem can the machine continue to move.
( 2 ) pay attention to the fact that the oil level should be between the two oil lines of the sight glass. if the oil level is too high, it will cause bad phenomena such as starting difficulty, oil return, oil injection, etc. if it is too low, it will affect the vacuum degree. When the amount of oil is insufficient, it should be filled through the filling hole. Note that the oil level of the pump that has been stopped for a long time will drop, and the oil level will only rise after the pump is continuously operated for a few revolutions.
( 3 ) turn on the cooling water
( 4 ) open the valve on the pump inlet port. the opening size depends on the specific situation.
2. for the rotary vane vacuum pump installed for the first time, a test run should be carried out first. at this time, the pump should be free of improper vibration and special impact noise, the motor should not be overloaded, and the oil temperature and the limit vacuum degree should conform to the technical specifications.
3. when stopping the rotary vane vacuum pump, shut off the valve at the intake port first. if equipped with a bleeder valve, deflate the pump, cut off the power supply, and then stop the water supply.
4. precautions for use of rotary vane vacuum pump:
( 1 ) always pay attention to the oil level.
( 2 ) slowly open the valve after starting the pump.
( 3 ) always pay attention to whether the pump operates normally, whether there is any special noise, and whether the motor is overloaded.
( 4 ) pay attention to whether the cooling water is interrupted.
( 5 ) pay attention to the pump temperature rise does not exceed 40 ℃
( 6 ) if the temperature of the rotary vane vacuum pump drops below 5 ℃ after shutdown, the cold water in the pump must be removed.
