Structural Functions:

A.SDS desalinate pump is made for pressuring and

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

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

EPT overall performance variety satisfies for pump’s service situation. SDS variety desalination

pump is designing for seXiHu (West EPT) Dis.Hu (West EPT) force and offering To adapt the best material to press and

deliver seXiHu (West EPT) Dis.Hu (West EPT) which assure corrosion resistance and strain resistance EPT planning of

bearing lubrication and cooling to suit for various applicationThe sealing composition among suction

chamber and discharge chamber which lessen leakage, reduce maintenance time and improve supply efficiency

Low pressure zone is close to mechanical seal with fXiHu (West EPT) Dis.Hu (West EPT) pipe drinking water to guarantee great functionality

and EPT services daily life of mechanical seal.

B.SDS desalinate pump of compact construction

The major parts are casing, impeller, shaft,shaft

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

and sensible construction, occupy significantly less room by decreasing the un-

necessary balance unit.

C.SDS desalinate pump is effortless to servicing

The casing is consisting of upper casing and lower casing.

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

ump because of the structure. It only needs to open higher casing alternatively of disassembling motor and pipe.

D.SDS desalinate pump undertake the self-stability mechanical


The delivery chambers are uniform distribution to balance the radial power. EPTTellers are

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

calculating EPTT and experimental verification. The essential of impellers are symmetrically organized to

harmony element of the radial deflection. Strictly dynamic balance is adopted on rotor elements

to take away the unbalanced mass and adopted elastic couplings to harmony the radial drive.

1. Inspection prior to commencing

Be confident to check out the followings:

(1) Insure pump plate mounted on basis

(2) Insure coupling and pump unit alignment

(three) Insure piping related by demands

(4) Insure motor set up by Set up and procedure instruction

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

(six) Insure the coupling guard installed

(seven) Insure the operator totally understand the security specification that they need to obey and the failures may possibly be happened

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

(9) Insure the shaft seal mounted by operation instruction

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

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

(twelve) Insure the air trapped in pump escaped.

two. Shaft Seal

Open valves appropriately for stuffing box seal

three. Air exhaust

EPT and piping should fill of medium ahead of beginning, there are two approaches: development of EPT or priming. If the pump operated on the suction point out, eXiHu (West EPT) Dis.t gas by bolt hole on top of the pump casing.

Be aware: When generation of EPT, evacuate air by bolt gap on leading of the pump casing. When priming, open equally facet reduced stress volute chamber of pump casing and the prime plug, to get rid of pump vibration by remained air in pump.

four. Beginning

(one) Near outlet valve

(two) Open inlet valve completely

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

(4) Beginning pump after finishing over procedures

(five) When the method commencing deliver medium and the strain looking through at strain gauge increase up, open up outlet valve gradually.

Notice: Forbid pump operating with out liquid! Only shut outlet valve when the pump begin and shutdown, in any other case will harm the pump by overheating.

5. Procedure


Validate running level

In accordance to Q-H functionality curve of pump, ability Q may differ with the actual procedure head. The head depended on the method head (incXiHu (West EPT) Dis.Hu (West EPT) Dis. the altitude big difference among inlet and outlet, piping, valves, radiator and so on). So the pump actually operating point B relies upon on pump efficiency

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

Once capacity settled, the shaft EPTT, effectiveness, NPSH settled as properly. EPT has minimal doing work selection. The least capability are shown as Qmin in Q-H efficiency curve. MaXiHu (West EPT) Dis.mum capacity are depended on the cross point of pump tolerance NPSH and technique valid NPSEPT. Adjust valve can modify overall performance curve Q-EPT of method, thereby modify operation performance, tends to make pump operation secure and large efficiency.

(two) Procedure management

JCEP spend focus to followings:

a. EPT must work stably

b. Forbid pump functioning with out liquid

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

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

operation temperature significantly less than a hundred ordmC.

e. Verify oil level often if use slender oil. Deep groove ball bearing of grease lubrication no want regimen servicing.

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

g. Periodical inspection and start off jury pump.

h. Check auXiHu (West EPT) Dis.liary piping whether or not related effectively.

i. Check out elastic component of coupling, if worn exchange quickly.

j. For stuffing box seal there ought to have a sligEPTT drip when running, push stuffing box gland carefully till there is a sligEPTT drip (about 15-30 fall/min ).

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

beginning handful of hours. If the seal leakage enhance steadily and get to about 30-60drop/min, ought to verify or adjust mechanical seal.

6. Shutdown

Close discharge valve.

Insure the pump unit stop effortlessly when shutdown the motor. EPT must have a proper soon after-managing interval, cut warmth source at this time, so that the sent medium can great down fully and avoid of making any warmth inside pump.

Shut suction valve if pump end function for a EPTT period of time of time.

Close auXiHu (West EPT) Dis.liary piping, the shaft seal ought to use seal lubricant even even though at stopped state. Evacuate all medium in pump and piping when freeze or end work for a EPTT-term, so as not to frost crack.

seven. Storage

Every single pump has inspected strictly just before shipping. EPTmmend to undertake pursuing methods to store pump.

(1) Retailer new pump

If keep pump at indoor, thoroughly clean dry place and follow the storage specifications, the EPTTest storage time is twelve months.

(two) If equipment is to be stored for EPTT durations of time ought to adhere to under processes.

a. EPT ought to keep in set up state and inspect work problem often. Begin pump as soon as every single month or every single three months (about five minutes). Check out operating condition prior to beginning pump to insure there is ample liquid.

b. Dismantled pump from piping and check out it in accordance to EPT to 5.four. Apply protective agent on within pump casing eEPTTly the hole of the impeller, implement on suction and discharge, then go over the suction.

c. Operation after storage

Examine and maintain completely prior to starting pump, eEPTTly shaft seal and bearing lubricant. Reinstall all security defense products in accordance to prerequisite before starting.
