China 12 Inches SSuction Pump for Suction Sto SBarge Sale

12 inches Sand suction pump for suction sand to sand barge sale

Introduction:

WS type Dredging Pump is horizontal, single-stage cantilevered structure, which is designed to meet the requirement of the contractor demanding and comprehensive dredging requirement. WS type dredge pump impeller passage is very wide, to continuous pumping gravel or high plastic clay and not happens jam. The minimal amount of wear parts design in these dredge pumps results in reduced wear, long life and lower maintenance which translates into less downtime, significant cost savings and dredging good performance within high efficiency.
200 WS - 500 WS type dredge pump integral by a single pump shell, single stage single suction cantilever horizontal structure, press and gear box of the connection way all can provide two kinds of typical structure, namely take bracket type and pump box and type. Own bracket type lubrication way as the grease lubrication or thin oil lubrication.
600 WS - 1000 WS type dredge pump overall adopts double pump shell, single stage single suction cantilever horizontal structure, bring their own bracket, lubrication way as the forced thin oil lubrication. Double pump shell the safety and reliability of the design makes sheath always can use to close to wear through, and when sheath rupture, pump room will not fill.

Workshop Photos
NAIPU PUMP is a whole processing company, Start from Modeling Workshop,Casting Workshop,Heat treatment Workshop,Machining Workshop ,Assembly Workshop and Pump Testing Workshop are all by us. So we are modernization and integrated company to satisfy the requirement of the changing needs of market.
Quality Control System
We have about 15-30 QC,we test each pump and parts before delivery.
We set various check points along the whole production line,which throughout Raw Material,Charging Material,Surface and Heat Treatment checking,Material Analysis,Spare Testing and Pump Testing etc.
We have established a strict QA and QC system,we can provide quality control records such as "Spectrum Detection" "metallographic Microscope Inspection" "Block Test" "Ultrasonic Flaw Detection" " Penetration Testing"etc. And related test reports to our clients if necessary, such as " Material Test Report " " Dimensional Test Report " " Rotor Balancing Test Report " " NDT Test Report " " Hardness Inspection Report " etc.
Possible Faults and Settlements

Faults Reason Settlement1.Pump fails to discharge any water,The hand of pressure gauge beat violently 1.Suction pipe don't have enough water.
2.Suction pipe blocked or the valve is locked.1. Inject enough water
2.unlock the inlet valve,clear the blocks
3.Exclude the air leakage 2.The pump can't discharge water,the hand of vacuum meter beat heavily. 1.The inlet valve is unlocked or silted up.
2.The resistance of suction pipe is too big or silted up.
3.The height of suction is too high. 1.Unlock the valve or desilting
2.improve the design of suction pipe or desilt
3.Lower the height of the installation.3.The pump can't discharge water,pressure gauge shows heavy pressure.1.The resistance of the discharge pipe is too big.
2.The impeller blocked
3.The speed is slow.1.Check and adjust the outlet pipe.
2.Clear the impeller
3. Improve the speed.4.The pump doesn't rotate The volute is silted up by the blocks. Clear the blocks5.The capacity is not enough 1.The blocks of the impeller or the inlet or outlet pipe.
2.The abrasion of the impeller is heavily.
3.The speed is low to normal
4.Pump is installed unreasonably or the leakage of the inlet pipe.
5.The transporting height is too high,the loss of the resistance of the inside pipe are too big.
6.The inlet valve not open enough or blocked
7.The packing seal leaks1.Clear the impeller or pipe.
2.Change the impeller
3.Adjust the speed
4.Install again or stop leaking.
Decrease the height of the transport or reduce the resistance.Unlock the inlet valve Compress the packing tightly6.The motor of the pump is overloaded 1.The head of the pump exceeds the head of the working condition.
2.Not consider the slurry density when selecting the pump.
3.The packing press tightly1.Turn down the outlet valve,cut the impeller or lower the speed.
2.Select the motor again.
3.Adjust the the screw of the packing gland 7.Abnormal sound in the pump, and no water out1.The resistance of the inlet pipe is too big.
2.The height of the suction is too high.
3.Cavitation occurred there is air in the inletThe temperature of the liquid is too highClear the suction pipe and sluice valve.Lower the height of the suction Adjust the water valve and let the pump operate in the defined limits.Block the leakage.Lowering the liquid temperature.8.pump vibrates1.pump cavitate
2.The block of the impeller single vane
3.The no concentricity between the pump shaft and motor shaft
4.Fasteners or foundation loose1.Adjust the water valve ,lower the height of the installation,reduce the resistance of the inlet.
2.Clear the impeller
3.Alignment again
4.Fasten the screw,and reinforce the foundation.9.Bearing is overheat 1.lock the cooling water
2.lubrication is not good.
3.the lubrication oil is not clear
4.the wrong direction of the thrust bearing.
5.there is something wrong with the bearing.Open the cooling waterAdjust the oil quantity Clear the shaft,change oilAccording to the inlet pressure,adjust the direction of the thrust bearing.Change the bearing 10.Packing short life The material of packing is not good Change the packing 11.pump leak oil1.High oil level
2.The rubber parts invalid
3.Assembly problem1.Lower the oil level
2.Change rubber spares
3.Adjust the assembly
12 Pump head leaking 1.The rubber parts not press wellAssembly again or press tightly
