1. The suction and exhaust volume of the vacuum degree from 40% to 90% or the pressure from 0.05MPa to 0.15MPa varies with the amount of water supply, the gap between the impeller and the side cover, and the gap between the impeller and the side cover. Especially when the flow rate is small, if the adjustment is not accurate, it is more likely to cause small flow
2. The values in the table are obtained under the following conditions: ①Water temperature 15℃; ②Air 20℃; ③Gas relative temperature 70%; ④Atmospheric pressure 0.1013MPa
3. The performance deviation in the table does not exceed 5%)
