Why do Roots vacuum pump units require water replenishment?

　　Why is it necessary to add water to a Roots vacuum pump system? What is the purpose of adding water to such a system? Adding water enables the use of energy to effectively work on the gas, thereby improving efficiency. The water should be added at the moment when the liquid stops doing work on the gas, that is, at the highest point of the compression chamber; this way, the system receives sufficient energy to start working again during the next cycle. Guangdong Association of Fan Manufacturers explains to everyone the reasons for adding water to Rohts vacuum pump units: 1. The loss of liquid in the liquid ring of the Rohts vacuum unit as it flows out through the exhaust port; 2. The end-face gap between the sealed pump body and the impeller; 3. The compression heat generated by the compressed gas discharged by the Rohts vacuum unit; 4. Cooling and lubricating components such as the packing and the packing gland in the Rohts vacuum unit. 　　If a large amount of water is added to the Roots vacuum pump system, this excess water occupies some of the gas space (which can also be attributed to an increase in the thickness of the water ring), resulting in a decrease in the volume of gas and in the exhaust pressure. Excessive water volume also increases power consumption, reduces efficiency, and causes noise and vibration. This makes the operation of the Roots vacuum pump unit highly unstable, causing large amounts of water to be ejected periodically and pulsatively from the exhaust port. 　　If the amount of water supplied to the Roots vacuum pump unit is low, the heat generated during compression cannot be adequately dissipated, which leads to an increase in the temperature of the water ring and the gas flowing through it. As a result, the volume of gas handled and the level of vacuum decrease. If too little water is supplied, the wear and damage to the water ring cannot be compensated for, which not only further reduces performance but also causes the pump to stop working due to the inability of the water ring to function properly. 　　To improve the operational efficiency of rotary vane vacuum pump units, it is necessary to supply an appropriate amount of water – neither too much nor too little – in order to ensure proper operation of the equipment. 　　If this situation occurs, you can follow the steps outlined above, or consult the manufacturer of the rotary vane blower and ask their technical staff for advice. Guangdong Association of Fans recommends that when using Rohter vacuum pump units, it is best to follow the instructions provided by the Rohter fan manufacturer. YueXie Fans: http://www.yue*efj.com/
