Filter Press Feeding Pumps 

 

Product Description

Naipu® NP-ZJW series filter press feeding pump accept unique hydraulic desin and installation mode of the

impeller,ensure that its pump performance curve be more steep than normal pumps,is more suitable to use in the 

filter press feed varies according to the changes of the resistance in order to realize the large capacity,

low pressure feeding and low capacity,high pressure filter.The pump is widely used in the coal washery,

environmental protection,aluminum factory,smelting plant etc.

        Faults

    Reason

      Settlement

1.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 cant 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 cant 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 doesnt rotate

The volute is silted up by the blocks.

Clear the blocks

5.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 leaks

1.Clear the impeller or pipe.

2.Change the impeller

 

 

3.Adjust the speed

4.Install again or stop leaking.

 

 

5.Decrease the height of the transport or reduce the resistance.

6.Unlock the inlet valve

 

7.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

4.there is air in the inlet

5.The temperature of the liquid is too high

1.Clear the suction pipe and sluice valve.

2.Lower the height of the suction

3.Adjust the water valve and let the pump operate in the defined limits.

4.Block the leakage.

5.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.

1.Open the cooling water

2.Adjust the oil quantity

3.Clear the shaft,change oil

4.According to the inlet pressure,adjust the direction of the thrust bearing.

5.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
