b.Change the pump supply water such as the figure 1 medium,( b),( d),( e), throw away the electromagnetism valve in which, supply water thus to have two sets to change the pump of Æµ ( on use on have) in the system, with each other for provide for use.The control changes the minimum discharge of the pump of for total use 40% of the water quantity in order to circulate the discharge( A), be the useless door to use the water, the circulating discharge that changes the pump of is an A;When the customer uses the water quantity< A, a part of discharges in A provide the customer, a part the conduct and actions return to water circularly;When the customer uses the water quantity= A, all of the discharge of A provide the customer, taking care of to return to amount of water current to zero circularly in the road at this time;When the customer uses the water quantity> A, along with the electrical engineering turn soon of change, the variety that changes the pump of to measure with the customer water carries on changing the water supply of, returning to return to amount of water current to zero circularly in the pipe line at this time.If minimum discharge enactment that changes the pump of pimping words, circulate the current velocity in the tube road very small, the efficiency is low, economizing on energy not to show the;But if make the minimum discharge enactment that changes the pump of use 40% of the water quantity> total, the current velocity would be very big, the fluid matter can't guarantee, so make the minimum discharge control that changes the pump of use 40% of the water quantity at total is proper.Compared with the method a, at use the water quantity< A, the water hases been be placed in the circulating appearance, but consume the electricity more.

c.Change the pump of + circulation the pump supply water

Such as the figure 1 medium,( b),( d),( e), throw away the electromagnetism valve in which, make the amount of water to settle for use the water quantity of 1.500%, have the useless door to use the water in spite of, return to amount of water current to all press to make the amount of water circularly of 1/300% circulation, the variety that changes the pump of to then use the water quantity according to the customer carries on changing the water supply of .Compared with the method b, often circulate the tube road to keep circulating appearance, but make the water equipments increment, invest the aggrandizement, cover to compare greatly, consume electricity much.

4 supply water to take care of the material

A few in common use and pure pipe line materials are as follows:

The ¢Ù stainless steel tube.Advantage:The anti- high pressure ability is strong, the anti- decay, anti- rust the ability is strong;
