Sujet : Water ring vacuum pump maintenance code

Water ring vacuum pump maintenance code: When the vacuum pump is in normal operation, it must observe whether there is vibration, listen to the noise in the pump, and set the stuffing box and bearing temperature (the normal bearing temperature must not be 350 C higher than the ambient temperature, but The operating temperature must not exceed 70 ° C). If the temperature is too high, stop immediately and check the cause.

  Water ring vacuum pump maintenance code

  1. Before starting, check whether the direction of rotation of the motor matches the direction of rotation of the pump. Whether the bearing is running and the lubrication is normal. Check if the packing is properly pressed and the packing cannot be pressed too tightly. Normally packed packing can cause water in the pump to leak out of the water. Take the oil-soaked asbestos rope as a dip, then pour the cooling water from the cooling pipe on the pump (connected to the screw hole (16) on the side of the pump body). The steam separator is filled from the steam separator. Also check that the suction line connection is tight before turning on the pump.

  2. When the vacuum pump is in normal operation, it is necessary to observe whether there is vibration, listen to the noise in the pump, and set the stuffing box and bearing temperature (the temperature of the normal bearing should not be higher than the ambient temperature by 350 C, but the working temperature must not exceed 70 ° C). If the temperature is too high, stop immediately and check the cause.

  3. When the vacuum pump is used as a vacuum pump for water pumping, all the air in the pump will be sucked out during the operation until the water is sucked out of the pump, then the pump is started. After the pump is working normally, the vacuum pump is stopped, and the suction line is cut off. The door is closed.

  4. After the vacuum pump is stopped, the water in the pump body should be drained, especially during the freezing season, so as not to cause the pump to freeze. If you are going to stop using it for a long time. * Soak all the parts of the pump and dry it. Apply butter or anti-cast grease to the rotating parts, reinstall it, and put a suction plug on the suction port and the discharge port. The place to take a dry bath is preserved.
