Precautions for switching on and off roots vacuum pump

In fact, if the roots vacuum pump is switched on and off in an incorrect way, it will have a great loss impact on the roots pump equipment. For a long time, it will seriously affect the normal use of the equipment and even reduce the service life of the equipment. Therefore, you must pay attention to some relevant matters when switching on and off roots pump equipment to avoid wrong operation, such as: 1. Power on. Roots vacuum pumps are generally used in conjunction with the previous stage pumps. Except for multistage, wet and air-cooled Roots pumps, equipment damage caused by excessive differential pressure shall be avoided. Therefore, before starting the roots pump, start the front stage pump, open the valve on the pre pumping pipeline of the front stage pump and the inlet and exhaust valve of the roots pump, close the valve on the pre pumping pipeline after the pressure in the system reaches the allowable inlet pressure of the roots pump, and then start the roots pump. 2. Shutdown shutdown. First, close the air ballast valve of the front stage oil seal mechanical pump, then close the inlet valve of Roots vacuum pump, and then stop roots pump first and then the front stage pump. Do not mistake the shutdown procedure. While stopping the front stage pump, immediately vent the air at the air inlet of the front stage pump and close the cooling water inlet valve. Therefore, it is necessary to operate according to the correct mode of switching on and off, and pay more attention not to make mistakes in the operation steps of switching on and off, otherwise the wrong operation sequence will not only lead to the failure of switching on and off, but also have a great adverse impact on Roots vacuum pump. And Xiaobian suggests that you can take relevant maintenance measures after each use of roots pump equipment, so as to prolong its service life.
