Roots vacuum pump preparation before operation

  • Check if the level of the fore-pump water tank is more than 3/4 of the water tank, if it is insufficient, make up.

  • Check whether the water used in the water tank is clean. It is not allowed to use sewage containing sediment, so as not to block the pipeline, cause the impeller to wear, increase the motor load and cause failures, and affect the service life of the pump.

  • Check the oil level of the lubricating oil in the middle pump and the main pump. It must be more than 3/4 of the oil window. At the same time, check the color of the lubricating oil. If the roots vacuum pump has milky white or black impurities, notify the mechanic to replace the lubricating oil.

  • Check whether the circulating cooling water circuit of the intermediate pump and the main pump is intact, open the circulating cooling water inlet and outlet valves, and check whether the circulating cooling water inlet and outlet are normal.

  • Check whether the drain valve of the buffer tank at the bottom of the intermediate pump is closed.

  • Check whether the circuit of the roots vacuum pump systemis intact and the instructions of the control cabinet are normal.

  • Check whether the starting pressure of the intermediate pump and the main pump of the electrode contact pressure gauge of the vacuum pump unit is normal.
