Structural Functions:

A.SDS desalinate pump is developed for pressuring and

transporting the seXiHu (West EPT) Dis.Hu (West EPT)

EPT model is EPTTized planning for seXiHu (West EPT) Dis.Hu (West EPT) desalination pump with smoothing efficiency.

EPT overall performance range suits for pump’s services situation. SDS type desalination

pump is designing for seXiHu (West EPT) Dis.Hu (West EPT) strain and offering To adapt the very best content to push and

provide seXiHu (West EPT) Dis.Hu (West EPT) which ensure corrosion resistance and strain resistance EPT creating of

bearing lubrication and cooling to go well with for various applicationThe sealing construction among suction

chamber and discharge chamber which minimize leakage, decrease maintenance time and improve shipping and delivery effectiveness

Minimal strain zone is around mechanical seal with fXiHu (West EPT) Dis.Hu (West EPT) pipe drinking water to assure excellent overall performance

and EPT services lifestyle of mechanical seal.

B.SDS desalinate pump of compact framework

The primary elements are casing, impeller, shaft,shaft

sleeve, dress in ring, bearing seat, coupling, and etc. It has compact

and reasonable composition, occupy much less room by decreasing the un-

needed balance unit.

C.SDS desalinate pump is easy to maintenance

The casing is consisting of higher casing and decrease casing.

The inlet and outlet are situated on every sides of the casing. Ax-is vertical with the shaft, It is quite straightforward servicing for the SDS sort p

ump due to the fact of the composition. It only wants to open upper casing instead of disassembling motor and pipe.

D.SDS desalinate pump undertake the self-equilibrium mechanical


The delivery chambers are uniform distribution to harmony the radial pressure. EPTTellers are

symmetrically or back-to-back arranged to stability aXiHu (West EPT) thrust. Thickening the shaft by enhance

calculating EPTT and experimental verification. The key of impellers are symmetrically arranged to

balance portion of the radial deflection. Strictly dynamic stability is adopted on rotor elements

to get rid of the unbalanced mass and adopted elastic couplings to balance the radial power.

Safety measures

1. Inspection ahead of starting up

Be sure to check out the followings:

(one) Insure pump plate fastened on foundation

(two) Insure coupling and pump unit alignment

(3) Insure piping connected by needs

(four) Insure motor put in by Installation and procedure instruction

(5) Insure the rotor of pump rotate easily (at lEPT a circle)

(6) Insure the coupling guard mounted

(7) Insure the operator totally realize the protection specification that they must obey and the failures could be occurred

(eight) Insure the shaft seal liquid or cooling liquid lead-in by specifications

(nine) Insure the shaft seal installed by procedure instruction

(10) Insure the auXiHu (West EPT) Dis.liary gadget set up by operation instruction (If they eXiHu (West EPT)

(eleven) nsure the bearing have lubricated nicely, eEPTTly insure new pump grease or slender oil do not reduce or go poor

(12) Insure the air trapped in pump escaped.

two. Shaft Seal

Open up valves effectively for stuffing box seal

three. Air exhaust

EPT and piping need to fill of medium ahead of starting, there are two methods: development of EPT or priming. If the pump operated on the suction state, eXiHu (West EPT) Dis.t fuel by bolt gap on best of the pump casing.

Notice: When creation of EPT, evacuate air by bolt gap on prime of the pump casing. When priming, open up equally side minimal force volute chamber of pump casing and the prime plug, to get rid of pump vibration by remained air in pump.

four. Starting

(one) Close outlet valve

(2) Open up inlet valve fully

(three) Open up all auXiHu (West EPT) Dis.liary piping (cooling, heating, sealing, rinsing and lubricant liquid), and verify all ability and pressure

(4) Commencing pump right after finishing previously mentioned procedures

(5) When the method starting up provide medium and the strain reading at force gauge rise up, open outlet valve little by little.

Note: Forbid pump functioning without having liquid! Only close outlet valve when the pump start off and shutdown, or else will damage the pump by overheating.

5. Procedure


Verify working level

According to Q-H overall performance curve of pump, capacity Q may differ with the true operation head. The head depended on the technique head (incXiHu (West EPT) Dis.Hu (West EPT) Dis. the altitude big difference in between inlet and outlet, piping, valves, radiator and so on). So the pump in fact running position B depends on pump functionality

curve Q-H and system efficiency curve Q-EPT.

After potential settled, the shaft EPTT, effectiveness, NPSH settled as nicely. EPT has minimal working range. The bare minimum ability are proven as Qmin in Q-H efficiency curve. MaXiHu (West EPT) Dis.mum potential are depended on the cross point of pump tolerance NPSH and program legitimate NPSEPT. Alter valve can adjust efficiency curve Q-EPT of technique, thus modify operation performance, helps make pump operation secure and high performance.

(two) Procedure management

JCEP spend focus to followings:

a. EPT ought to work stably

b. Forbid pump functioning without liquid

c. To avoid medium temperature increase up, pump can not be run EPTT period when shut outlet valve

d. EPTTly, the bearing temperature not greater than 35 ordmC of ambient temperature, complete

procedure temperature much less than a hundred ordmC.

e. Check out oil amount frequently if use slim oil. Deep groove ball bearing of grease lubrication no need to have program routine maintenance.

f. Do not shut inlet valve (if it is eXiHu (West EPT) when pump working.

g. Periodical inspection and start jury pump.

h. Examine auXiHu (West EPT) Dis.liary piping regardless of whether related well.

i. Check elastic component of coupling, if worn replace right away.

j. For stuffing box seal there ought to have a sligEPTT drip when running, thrust stuffing box gland gently until finally there is a sligEPTT drip (about 15-thirty drop/min ).

For mechanical seal the seal leakage ought to minimize progressively. It is about -5drop/min following

starting number of hours. If the seal leakage increase progressively and achieve about thirty-60drop/min, ought to verify or change mechanical seal.

six. Shutdown

Close discharge valve.

Insure the pump unit quit efficiently when shutdown the motor. EPT must have a correct right after-managing period of time, lower warmth supply at this time, so that the sent medium can great down completely and steer clear of of generating any heat inside of pump.

Close suction valve if pump quit operate for a EPTT period of time of time.

Close auXiHu (West EPT) Dis.liary piping, the shaft seal should use seal lubricant even however at stopped state. Evacuate all medium in pump and piping when freeze or quit perform for a EPTT-expression, so as not to frost crack.

7. Storage

Every single pump has inspected strictly ahead of shipping. EPTmmend to undertake following processes to shop pump.

(1) Keep new pump

If retailer pump at indoor, clear dry spot and stick to the storage needs, the EPTTest storage time is 12 months.

(2) If gear is to be stored for EPTT periods of time should adhere to below procedures.

a. EPT ought to preserve in installation condition and inspect perform issue often. Begin pump as soon as every month or every three months (about five minutes). Verify managing problem ahead of commencing pump to insure there is adequate liquid.

b. Dismantled pump from piping and check out it in accordance to EPT five.1 to 5.4. Utilize protecting agent on inside of pump casing eEPTTly the hole of the impeller, use on suction and discharge, then cover the suction.

c. Operation after storage

Inspect and sustain entirely just before starting up pump, eEPTTly shaft seal and bearing lubricant. Reinstall all protection safety products in accordance to necessity ahead of commencing.
