Structural Functions:

A.SDS desalinate pump is designed for pressuring and

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

EPT product is EPTTized planning for seXiHu (West EPT) Dis.Hu (West EPT) desalination pump with smoothing overall performance.

EPT functionality assortment fits for pump’s service situation. SDS kind desalination

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

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

bearing lubrication and cooling to fit for diverse applicationThe sealing composition among suction

chamber and discharge chamber which decrease leakage, lessen upkeep time and boost shipping effectiveness

Low stress zone is in close proximity to mechanical seal with fXiHu (West EPT) Dis.Hu (West EPT) pipe h2o to promise good overall performance

and EPT support lifestyle of mechanical seal.

B.SDS desalinate pump of compact composition

The principal components are casing, impeller, shaft,shaft

sleeve, put on ring, bearing seat, coupling, and and so forth. It has compact

and sensible construction, occupy much less space by reducing the un-

necessary harmony device.

C.SDS desalinate pump is simple to servicing

The casing is consisting of higher casing and decrease casing.

The inlet and outlet are located on every single sides of the casing. Ax-is vertical with the shaft, It is quite easy routine maintenance for the SDS variety p

ump since of the structure. It only wants to open upper casing alternatively of disassembling motor and pipe.

D.SDS desalinate pump undertake the self-balance mechanical


The delivery chambers are uniform distribution to equilibrium the radial force. EPTTellers are

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

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

equilibrium part of the radial deflection. Strictly dynamic equilibrium is adopted on rotor elements

to take away the unbalanced mass and adopted elastic couplings to balance the radial force.

one. Inspection just before starting up

Be sure to check the followings:

(one) Insure pump plate fastened on foundation

(2) Insure coupling and pump device alignment

(3) Insure piping related by demands

(four) Insure motor mounted by Set up and procedure instruction

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

(six) Insure the coupling guard installed

(seven) Insure the operator entirely realize the protection specification that they must obey and the failures may be transpired

(8) Insure the shaft seal liquid or cooling liquid guide-in by specifications

(9) Insure the shaft seal set up by procedure instruction

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

(11) nsure the bearing have lubricated properly, eEPTTly insure new pump grease or skinny oil do not lessen or go poor

(12) Insure the air trapped in pump escaped.

two. Shaft Seal

Open valves correctly for stuffing box seal

three. Air exhaust

EPT and piping must fill of medium just before beginning, there are two strategies: generation of EPT or priming. If the pump operated on the suction state, eXiHu (West EPT) Dis.t gas by bolt hole on leading of the pump casing.

Be aware: When creation of EPT, evacuate air by bolt hole on top of the pump casing. When priming, open each aspect minimal force volute chamber of pump casing and the top plug, to get rid of pump vibration by remained air in pump.

four. Commencing

(one) Shut outlet valve

(2) Open up inlet valve entirely

(3) Open up all auXiHu (West EPT) Dis.liary piping (cooling, heating, sealing, rinsing and lubricant liquid), and check out all potential and force

(4) Starting up pump right after ending previously mentioned techniques

(five) When the method starting up provide medium and the force studying at stress gauge increase up, open outlet valve little by little.

Be aware: Forbid pump operating with out liquid! Only near outlet valve when the pump start and shutdown, in any other case will hurt the pump by overheating.

5. Procedure


Confirm running level

In accordance to Q-H efficiency curve of pump, ability Q varies with the actual operation head. The head depended on the technique head (incXiHu (West EPT) Dis.Hu (West EPT) Dis. the altitude difference between inlet and outlet, piping, valves, radiator and so on). So the pump actually functioning position B relies upon on pump efficiency

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

When potential settled, the shaft EPTT, efficiency, NPSH settled as properly. EPT has limited doing work assortment. The least capability are demonstrated as Qmin in Q-H overall performance curve. MaXiHu (West EPT) Dis.mum potential are depended on the cross stage of pump tolerance NPSH and technique legitimate NPSEPT. Alter valve can alter performance curve Q-EPT of method, thus adjust operation functionality, helps make pump operation stable and substantial efficiency.

(2) Operation administration

JCEP spend focus to followings:

a. EPT need to function stably

b. Forbid pump working with out liquid

c. To stop medium temperature rise up, pump can not be run EPTT period of time when near outlet valve

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

operation temperature considerably less than 100 ordmC.

e. Examine oil level regularly if use skinny oil. Deep groove ball bearing of grease lubrication no need routine routine maintenance.

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

g. Periodical inspection and start jury pump.

h. Check out auXiHu (West EPT) Dis.liary piping no matter whether related properly.

i. Check elastic factor of coupling, if worn change immediately.

j. For stuffing box seal there should have a sligEPTT drip when working, drive stuffing box gland carefully until there is a sligEPTT drip (about 15-30 drop/min ).

For mechanical seal the seal leakage must reduce slowly. It is about -5drop/min following

starting up few hours. If the seal leakage enhance slowly and achieve about thirty-60drop/min, must check or alter mechanical seal.

six. Shutdown

Shut discharge valve.

Insure the pump device stop effortlessly when shutdown the motor. EPT must have a appropriate following-working time period, reduce heat resource at this time, so that the sent medium can cool down totally and stay away from of generating any warmth inside of pump.

Shut suction valve if pump quit perform for a EPTT period of time.

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

7. Storage

Every pump has inspected strictly before shipping. EPTmmend to adopt following processes to retailer pump.

(1) Shop new pump

If keep pump at indoor, cleanse dry location and adhere to the storage requirements, the EPTTest storage time is twelve months.

(2) If tools is to be stored for EPTT durations of time must adhere to below methods.

a. EPT must maintain in set up point out and examine work problem regularly. Start pump once every month or each and every a few months (about 5 minutes). Verify managing situation just before commencing pump to insure there is ample liquid.

b. Dismantled pump from piping and verify it according to EPT to 5.four. Implement protecting agent on within pump casing eEPTTly the hole of the impeller, use on suction and discharge, then protect the suction.

c. Operation after storage

Inspect and sustain completely just before commencing pump, eEPTTly shaft seal and bearing lubricant. Reinstall all safety safety products according to prerequisite before starting.
