Notes for Shutdown Roots Vacuum Pump

  • Close the gas ballast valve of the front oil sealed mechanical pump (if the gas ballast valve of the front oil sealed mechanical pump is opened during operation).

  • Close the intake valve of the roots vacuum pump.

  • Stop the roots vacuum pump first, and then stop the fore vacuum pump. It is strictly forbidden to make mistakes in the shutdown procedure.

  • While the fore pump is stopped, the air inlet of the fore pump immediately enlarges the air.

  • Close the cooling water inlet valve.

  • If user need to stop using pump for a long time, or in winter to prevent pump freezing and cracking, open the drain valve to drain the remaining water in the fixed end cooling water.
