求翻译：由于真空系统的真空度不恒定，在一定间隔内变化，所以用水量也应该呈现一定的变化。随着真空度的递减，用水量作相应的增加；当到达临界值（设定值P=0.02 MPa）时真空泵动作，使真空储存罐的真空度升高，直至P=0.03 MPa，此时需要真空储存罐的体积较大，以保证真空泵不必频繁的启动，以节省电能是什么意思？

As the vacuum system of the vacuum is not constant, changes in a certain interval, so the water should also show some changes. With decreasing degree of vacuum, a corresponding increase in water consumption; When you reach the critical value (set value P = 0.02 MPa) when the vacuum pump operation, t

Vacuum System because the vacuum is not constant, within a certain interval, so changes to the quantity of water should also show a certain degree of change. Along with the claw vacuum, the volume of water; when it reaches a corresponding increase threshold value (set at P=0.02 ) MPa vacuum pump mov

Because the vacuum system vacuum degree is inconstant, changes in certain gap, therefore the water consumption also should present certain change.Along with the vacuum degree degression, the water consumption makes the corresponding increase; When arrives the marginal value (setting value P=0.02 MPa

Because of the vacuum system of the vacuum is not constant, changes within a certain interval, so water consumption should also render some changes. With the decline of vacuum, increasing water consumption accordingly; when you reach the threshold (set value P=0.02 MPa), vacuum pump action so that t
