Product Description

Mining dewatering high chrome metal material sand gravel slurry pump


 

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



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.

Unlock the inlet valve   Compress the packing tightly
6.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 tightly	1.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 out	1.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 inlet The temperature of the liquid is too high	Clear 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 vibrates	1.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 loose	1.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 water Adjust the oil quantity  Clear the shaft,change oil According 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 oil	1.High oil level 2.The rubber parts invalid   3.Assembly problem	1.Lower the oil level 2.Change rubber spares 3.Adjust the assembly
12 Pump head leaking	1.The rubber parts not press well	Assembly again or press tightly
