Liquid Ring Vacuum Pump Vacuum Degree Reduction Reasons
The vacuum degree of liquid-ring vacuum pump may decrease due to the relationship between time and utilization rate after long-term use. Let's see what causes the vacuum to decrease.
1. Surface Height of Working Circulating Water
The working circulating liquid should keep a certain height of liquid level. If the liquid level is too high, the separation of steam and water is difficult and the exhaust is not smooth, the vacuum degree of water ring vacuum pump will be reduced.
2. Cooler cleanliness
If the cooler is not clean enough, the cooling efficiency will be reduced. The working circulating water temperature will rise, the water in the suction area will vaporize, and the vacuum degree of the water ring vacuum pump will be reduced.
3. Working circulating liquid temperature
When the liquid ring vacuum pump operates, the suction zone is in a negative pressure state. If the temperature of the circulating water is higher than the saturation temperature corresponding to the negative pressure of the suction zone of the vacuum pump, the water in the suction zone will vaporize and the vacuum degree of the vacuum pump will be reduced.
Above is the three main reasons for the vacuum reduction of liquid ring vacuum pump. Detailed understanding of the above will help you to operate in the future. After understanding the reasons for the vacuum reduction of vacuum pump, it is necessary to timely repair the vacuum pump in order to avoid delaying normal use.
