In the process of using industrial equipment, the incorrect switch mode will cause certain loss to the equipment. If it is done for a long time, the service life of the equipment will be greatly shortened, and the roots vacuum pump is the same. Today, let's talk about the matters needing attention when turning on and off the roots vacuum pump?
Switch on and off of Roots vacuum pump
1. Boot up
In general, roots vacuum pump is used in combination with the front stage pump. In addition to multistage, wet and air-cooled Roots pump, it can avoid equipment damage caused by too high pressure difference. Therefore, before starting the roots pump, start the front pump, open the valves on the pre pumping pipeline of the front pump and the inlet and outlet valves of the roots pump, close the valves 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. Shut down
First of all, close the air ballast valve of the front stage oil seal mechanical pump, then close the intake valve of Roots vacuum pump, and then stop roots pump first, and then stop the front stage pump. Do not mistake the shutdown procedure. At the same time of stopping the front stage pump, immediately release the air to 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 on-off mode, and pay more attention not to make mistakes in the on-off operation steps, otherwise the wrong operation sequence will not only lead to the failure of on-off, but also have a huge adverse impact on the roots vacuum pump. And Xiaobian suggests that you can take some maintenance measures after using roots pump equipment, so as to prolong its service life.
