　　What are the reasons for the tripping of vacuum pump units? What causes failures in these vacuum units? As we all know, many problems can arise during the operation of vacuum pumps. So how can we address the issues related to the tripping of vacuum pump units and find solutions to them? YueXie Fans provides several points for analysis: 1. The suction inlet of the vacuum pump unit should not be connected from the bottom of the tank; it is sufficient to have only one suction pipe at the top of the tank. 　　(1) Because when air is drawn in from the bottom of the tank, after each use of the vacuum pump unit and once the unit stops operating, a negative pressure is created inside the tank. This negative pressure keeps the suction pipe connected to the vacuum pump unit, allowing water from the pump to be drawn into the tank. (2) When the vacuum pump unit is started again, a large amount of water that has accumulated at the bottom is drawn into the unit, resulting in an excessive load on the water ring vacuum pump and causing an overcurrent that leads to the shutdown of the pump. 2. When two vacuum pump units are connected together through a single pipeline, with no valves installed between them except for a check valve at the inlet, the check valve cannot provide complete sealing. 　　Since the vacuum pump units operate in a one-in-use and one-backup configuration, when one of them is in operation, it can draw in water from the other vacuum pump unit; in some cases, circulating water and air may even be drawn back through the exhaust pipe. This can also be the cause of the water ring vacuum pump unit shutting down. 　　I hope the information above can help everyone solve their problems. When using vacuum pump systems on a daily basis, it is important to follow the instructions provided by the Rotary Vacuum Pump manufacturer to avoid malfunctions. If you have any questions, you can call the YueXie fan manufacturer for consultation. 　　If you are not fully understanding the information regarding the vacuum pump units mentioned above or have different opinions, we kindly ask that you raise them promptly. We will have professionals explain things to you and discuss with you the issues you have raised. Thank you in advance for your assistance. Yue Xie Fans: http://www.yue*efj.com
