How should vertical conduit pump design type selecting?

Shandong Hairui Zhonglian Pump Industry Co. , ltd. The conduit pump that is a major produces manufacturer. When type selecting of client conduit pump, manufacturer of my company water pump can provide the before-sales service such as price of pump of conduit pump model, conduit, in order to offer client reference, and manufacturer of my water pump can provide the service of product of custom-built pump industry for the client. This product information is the knowledge that how should design type selecting about vertical conduit pump:

Above all:
One, listed and basic data:
The character of 1. medium: Medium name, proportion, viscosity, caustic, noxiousness.
The grain diameter that solid body contains in 2. medium, content how many.
3. medium temperature: (℃ )
The flow that 4. place needs
General industrial pump is negligible in technological process the leakage rate in pipeline system, but the impact that must consider the convection when craft changes to measure. If be to use,agriculture uses pump bright canal be defeated by water, still must consider leakage and capacity.
5. pressure: Absorb cistern pressure, discharge cistern pressure, the pressure in pipeline system falls (lift loss) .
Data of system of pump of 6. vertical conduit (sort of accessory of tubal diameter, length, conduit and amount, suck cistern to wait for) to the geometrical level that approachs cistern. If the word of need still should make device character curve.
When the design decorates conduit, should notice following item:
Diameter of conduit of A, logical choice, conduit diameter is big, fall in identical discharge, current rate is minor, obstruction loss is small, but the price is high, conduit diameter is small, can bring about obstruction loss to increase quickly, make the lift that chooses pump increases, deserve to take power to increase, cost raises with moving charge. Because this answers,consider integratedly from the angle of technology and economy.
Canal of B, eduction and correspondence of its pipe fittings consider can susceptive is bigger pressure.
C, conduit is decorated should decorate straight canal as far as possible, the accessory in reducing conduit as far as possible and narrow as far as possible conduit length, when must turning, the 3 ~ that the radius of bend of bend should be conduit diameter 5 times, angle is more than 90 ℃ as far as possible.
D, Vertical conduit pumpeduction side must furnish valve (ball valve or shut-off valve) and go against stop a powerful person. Valve is used adjust the operating mode dot of pump, go against stop a powerful person can prevent pump to invert when the liquid flows backwards, make pump avoids the blow of water hammer. (when the liquid flows backwards, can generate enormous retrorse pressure, make pump damages)
2, lift of pump discharge of affirmatory vertical conduit
Discharge decides really:
A, if lesser, normal, larger flow already gave out in manufacturing technology, should press larger flow consideration.
If manufacturing technology is medium it is B, normal to give out only discharge, lv of take an examination leaves the surplus with have certain.
To the pump of large flow low lift of Ns>100, discharge surplus is taken 5% , to the pump of Cheng of little flow soar of Ns<50, discharge surplus is taken 10% , the pump of 50-100, discharge surplus also is taken 5% , inferior to quality with the pump with moving abominable condition, discharge surplus should be taken 10% .
C, if basic data gives weight flow only, should conversion adult accumulates discharge.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is the introduction that how should design type selecting about vertical conduit pump, still think to this problem like you deep one pace understanding, or the problem that has price of model of type selecting of product of other pump industry, water pump, water pump, water pump needs to solve, contact this water pump manufacturer please, my company returns production to suck pump oneself, welcome you at any time seek advice.
