Introduction:

WS kind Dredging Pump is horizontal, solitary-stage cantilevered construction, which is designed to fulfill the prerequisite of the contractor demanding and extensive dredging need. WS sort dredge pump impeller passage is extremely wide, to continuous pumping gravel or substantial plastic clay and not takes place jam. The small quantity of use elements design in these dredge pumps outcomes in reduced dress in, lengthy lifestyle and reduced upkeep which translates into considerably less downtime, considerable expense financial savings and dredging excellent efficiency inside substantial efficiency.

two hundred WS – 500 WS type dredge pump integral by a single pump shell, single stage single suction cantilever horizontal construction, push and equipment box of the link way all can offer two varieties of common framework, specifically take bracket variety and pump box and kind. Personal bracket kind lubrication way as the grease lubrication or skinny oil lubrication.

600 WS – 1000 WS variety dredge pump all round adopts double pump shell, one stage single suction cantilever horizontal composition, deliver their possess bracket, lubrication way as the forced thin oil lubrication. Double pump shell the security and dependability of the design and style helps make sheath usually can use to near to put on by way of, and when sheath rupture, pump space will not fill.

Workshop Pictures

Naipu mainly Make Slurry Pumps, Sand Gravel Pumps, Dredging pumps etc.
We have Mould Workshop,Casting Workshop,Machining Workshop,Assemblying Workshop and many others.
Our Pumps and spares can be interchangeable with AH HH M L G AF SP collection.
We can do CZPT pumps and spares if you supply us drawings or samples.

High quality Control System 

We have about fifteen-30 QC,we take a look at every pump and elements before shipping.
We established a variety of verify details alongside the whole manufacturing line,which through Uncooked Substance,Charging Material,Area and Warmth Therapy examining,Content Investigation,Spare Testing and Pump Screening and many others.

We have established a strict QA and QC technique,we can supply top quality management data this kind of as “Spectrum Detection” “Metallographic Microscope CZPT” “Block Test”  “CZPT Flaw Detection” ” Penetration Tests”and so forth. And connected test studies to our clientele if needed, this sort of as ” Material Test Report ”  ” Dimensional Examination Report ”  ” Rotor Balancing Take a look at Report ”  ” NDT Test Report ”  ” Hardness CZPT Report ” and many others.

Feasible Faults and Settlements 
 

        Faults      Reason        Settlement
one.Pump fails to discharge any drinking water,The hand of stress gauge conquer violently  1.Suction pipe never have enough h2o.
2.Suction pipe blocked or the valve is locked.
one. Inject sufficient h2o
two.unlock the inlet valve,very clear the blocks
3.Exclude the air leakage 
2.The pump can not discharge h2o,the hand of vacuum meter conquer intensely.  1.The inlet valve is unlocked or silted up.
two.The resistance of suction pipe is way too huge or silted up.
three.The height of suction is too high. 
one.Unlock the valve or desilting 
two.increase the style of  suction pipe or desilt 
three.Reduced the top of the set up.

  1. Decrease the height of the transport or decrease the resistance.
  2. Unlock the inlet valve

 

  1. Compress the packing tightly
six.The motor of the pump is overloaded  1.The head of the pump exceeds the head of the working problem.
2.Not contemplate the slurry density when picking the pump.
3.The packing press tightly
one.Flip down the outlet valve,reduce the impeller or reduced the pace.
2.Pick the motor yet again.
three.Alter the the screw of the  packing gland 
seven.Abnormal sound in the pump, and no water out 1.The resistance of the inlet pipe is way too big.
2.The peak of the suction is as well large.
three.Cavitation occurred 

  1. there is air in the inlet
  2. The temperature of the liquid is too higher
  1. Obvious the suction pipe and sluice valve.
  2. Reduce the peak of the suction 
  3. Alter the water valve and permit the pump work in the described limitations.
  4. Block the leakage.
  5. Reducing the liquid temperature.
eight.pump vibrates 1.pump cavitate 
two.The block of the impeller single vane 
3.The no concentricity  between the pump shaft and motor shaft
four.Fasteners or basis free
1.Adjust the h2o valve ,lower the peak of the set up,lessen the resistance of the inlet.
2.Very clear the impeller
three.Alignment once again
4.Fasten the screw,and strengthen the basis.
nine.Bearing is overheat  one.lock the cooling water
2.lubrication is not excellent.
three.the lubrication oil is not distinct
4.the incorrect route of the thrust bearing.
5.there is something incorrect with the bearing.
  1. Open the cooling h2o
  2. Change the oil quantity 
  3. Clear the shaft,change oil
  4. According to the inlet stress,adjust the direction of the thrust bearing.
  5. Change the bearing 
10.Packing brief life  The materials of packing is not good  Modify the packing 
11.pump leak oil 1.Large oil stage
two.The rubber components invalid  
three.Assembly difficulty
1.Lower the oil level
2.Alter rubber spares
3.Modify the assembly
 
12 Pump head leaking  one.The rubber components not push properly Assembly again or press tightly
