Along with Screw vacuum pump The performance advantages have been recognized by more and more people, and the field of use is becoming more and more common. Screw vacuum pump At the time of operation, we must strictly operate according to the operation rules to achieve good results. Let's know what the starting method of the screw vacuum pump is.
Before using screw vacuum pump to vacuum, start the screw vacuum pump for 20 minutes or so. When the oil temperature rises, turn on the exhaust valve of the unit and stop pumping the unit. The gas valve should be opened to allow the steam to evaporate in time when the unit stops pumping. In the process of operation, if the main engine vacuum is very poor, the suction valve should not be driven too fast or too large. Otherwise, the LiBr solution is easily pumped out. The condensate at the bottom of the oil pump should be discharged in time, so as not to enter the vacuum pump and damage the vacuum pump. After the air pump is stopped, the vacuum pump should be kept running for 20 minutes before closing the unit exhaust valve, so that the steam in the pump will evaporate sufficiently to avoid corrosion in the pump. As long as it is confirmed that there is a non condensable gas in the unit, the vacuum pump can start the vacuum pump to stop pumping the unit, and do not blindly pump the vacuum to the unit, so as to avoid the damage of the vacuum pump and destroy the vacuum of the main engine.
The above is the screw vacuum pump start-up method, we must strictly operate according to the screw vacuum pump operation steps, in order to achieve good results, hope that the above content will help you, if you do not understand, you can contact us, you can also pay attention to our website, we will regularly update the website articles.
