Conduit pump sucks the case study that does not sail upstream

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 about conduit pump sucks do not sail upstream the knowledge of the reason:

Conduit pump is our company use IS centrifugal pump performance data and old model the length of conduit pump structure, it is to replace the pump of novel vertical conduit of the groovy product such as IS centrifugal pump, vertical multistage centrifugal pump.
Conduit pump sucks the case study that does not sail upstream to be as follows:
One, conduit revolution speed is too low
1) person is an element. Have quite because one part user firsts wife electromotor damages, match on another electromotor to drive at will, the result created flow little, lift is low smoke do not sail upstream sequential.
Mechanical failure of itself of 2) conduit pump. Nut of close solid of impeller and pump shaft loosens or pump shaft is out of shape bend, cause impeller to move more, chafe with pump housing directly, or bearing attaint, reduce conduit revolution speed likely.
Maintenance of 3) motivation plane is not recorded. Electromotor because winding burn down, and break magnetism, the winding in maintenance circles method of means of number, line, wiring is changed, or the breakdown in maintenance did not eliminate an element to also can make conduit revolution speed is changed thoroughly.
2, gas is free inside wirereinforced suction hose and pump housing
1) has some of userConduit pumpBefore starting not fill satisfies enough water; Look fill water to already spilled over from air-bleed hole, but not rotational pump shaft makes air complete eduction, in causing a few air to return rudimental wirereinforced suction hose or pump housing.
Direction of 2) and current of Duan Ni of level of wirereinforced suction hose of conduit pump contact applies 0.5% above to drop gradient, one aspect of the matter of entrance of join conduit pump is taller, do not want complete standard. Up cock, the meeting inside wirereinforced suction hose puts leave a blank to enrage, the vacuum in reducing conduit and conduit pump is spent, the influence is bibulous.
Filling of 3) conduit pump has worn away because of be being used for a long time or filling pressing loosens too, in causing a large number of water to cover gap from filling and pump shaft axis ejective, its are outside air enters conduit pump interior from these clearance as a result, affected carry water.
4) wirereinforced suction hose falls because of long-term dive, tube wall corrodes occurrence hole, the surface after conduit pump works drops ceaselessly, after these hole show water, air entered wirereinforced suction hose from hole.
Bent housing of 5) wirereinforced suction hose handles occurrence dehiscent fruit, wirereinforced suction hose and conduit pump joint appear little space, make air enters wirereinforced suction hose likely.
3, suck Cheng Taida
Some source of water are deeper, situation of some fountainhead periphery is evener place, and oversight conduit pump is concessional suck Cheng, arose bibulous little or suck at all do not sail upstream result. Should know conduit pump is bibulous buccal place can build vacuum to spend is to have limit, cheng is sucked to be 10 meters of water column about when vacuum tall, and conduit pump builds vacuum impossibly. Vacuum is spent big, make the hydrosphere inside pump is changed easily, adverse to conduit pump job. Each centrifugal pump has his bigger concessional suck Cheng, general 3 ~ 8.5 meters between, installation must not pursue convenient and simple only when conduit pump.
4, other factor influence
1) heart valve cannot be opened. It is conduit pump lays aside time normally too long, heart valve gasket is stuck dead, without bottom of washerbed down the livestock a powerful person may become rusty dead.
Net of colander of 2) heart valve is jammed; Or mesh is caused to jam in layer of the mud in heart valve dive.
3) impeller wears away serious. Impeller blades classics is used for a long time and wear away, affected conduit pump performance.
4) brake a powerful person or check valve have trouble or jam can cause discharge to reduce smoke do not sail upstream.
5) gives Lv conduit to collect leakage to also can affect the amount that carry water.
5, loss of the obstruction in conduit of current pass in and out is too big
Some users are measured, reservoir or water tower to fountainhead surface vertical distance still is less than conduit pump lift slightly, but the quantity that carry water small or carry do not sail upstream. Its reason often is conduit curved talk of too long, conduit is much, loss of the obstruction in current conduit is too big. Its reason often is conduit curved talk of too long, conduit is much, loss of the obstruction in current conduit is too big. 90 degrees of bent housing are usually bigger than obstruction of 120 degrees of bent housing, loss of lift of 90 degrees of each bent housing makes an appointment with 0.5 ~ 1 meter, obstruction of every 20 meters of conduit can make lift loss makes an appointment with 1 meter. In addition, partial user returns optional conduit pump to enter, diameter of canal giving a canal, these also have certain effect to lift.
Thank you to be mixed to the visit of above content very much read! This information is about conduit pump is sucked do not sail upstream the introduction of the reason, if you still want to have farther knowledge to this problem, or want to buy this relevant product, contact personnel of my company customer service directly please, my company returns production to suck pump oneself, welcome you at any time seek advice.
