ZWL Drainage Pump With Motor 

 

 

OVERVIEW:

ZWL Direct Connection Self-Priming Sewage Drainage Pump with Motor is a based a latest product based on research of the same technology abroad. The pump is combined with self-priming and sewage with shaft reverse outside mixture. Besides, special design in body and impeller can be used as self-priming water pump without installing base valve and water diversion, and suction of solid and fluid with macro fiber, which can be widely used in municipal sewage engineering, pond breeding, light industry, paper making, textile manufacturing, food, chemistry, electric undertaking, fiber, slurry, mixture of suspension.

 

Compared with the same product at home, direct connection structure is compact, less shake, good performance in self-priming, excellent in sewage drain, efficient and energy saving, easy maintenance and leading in sewage pump in China. Various technical performances is leading at home as well as reaching international advanced level with wide application and development prospect.

 

MODEL MEANING:

 

 

WORKING CONDITIONS:

l  Environment humidity 50°C, medium temperature 80°C, specialty in 200°C.

l  PH medium of cast iron ranges from 6-9, stainless steel is from 2-13.

l  Density of medium is less than 1240 kg/m3.

l  Self-priming height is less than 4. 5m-5. 5m, suction tube length is 10m.

l  Capacity of suspended particles passing is less than 60%of diameter pump outlet. fiber length is fifth times than pump diameter.

 

 

PARAMETERS:

 

 

CURVE:

 

 

PUMP STRUCTURE:

l  Check base horizontal before install.

l  Check breakdown in each part.

l  Body cannot be supported by tube.

l  Keep good sealing between pump and tube.

 

 

 

OUTLINE AND INSTALLATION DIMENSION:

 

 

STRUCTURE AND WORKING PRINCIPLE:

ZWL Direct Connection Self-Priming Sewage Pump is made up of motor, pump shaft, water-against ring, mechanical seal, pump cover, pump body, impeller, seal ring, waterproof plug, bottom plate, base, gas-liquid separation tube, discharge connection tube, water-adding valve, check valve plates, inlet connection tube, etc. Pump structure see on drawing.

 

Working principle: Liquid storage chamber in pump body is connected with upper reverse hole and lower circle hole composing the shaft reverse outside mix system. After pump shut off, a little liquid has been in pump body. When pump getting start, with push of impeller, liquid in body will be thrown out and go back to body through gas-liquid separation tube. As gas out of pump like a vacuum, it can work under self-priming.

 

PREPARATION AND OPERATION:

l  Check pump base and pump cover and other joint part whether is loosen.

l  Turn the fan of motor by hand to check whether it is stuck.

l  Open upper water-adding valve, feed water more than two-thirds of pump volume. Close the valve and never feed water again next time.

l  Turn on the pump for test run, as clockwise run from the motor.

l  Operate and observe whether pump is under normal. If not, please find out and fix it.

 

 

BREAKDOWN AND TROUBLESHOOTING:

Breakdown

Cause

Troubleshooting

No water comes out

1. Not enough water storage

2. Suction line leak

3. Voltage below level

4. High suction head or longer suction tube

5. Wrong direction of motor

6. Default phase

7. Heavier viscosity and density of medium

8. Higher head of delivery

1. Fill enough water

2. Eliminate gas leak

3. Adjust voltage

4. Reduce suction head or shorten tube

5. Adjust motor direction

6. Check wiring and repair

7. Dilute medium

8. Change pump or reduce head of delivery

Less water come out

1. Incorrect use. Impeller passage and suction tube is stuck.

2. Impeller badly worn

3. Seal ring damage

1. Clear out

2. Change impeller

3. Change

Pump is badly vibrated and noisy.

1. Unstable base

2. Bearing badly worn

1. Reinforce

2. Change it

Motor heating

1. Higher flow and overload operation

2. Friction

3. Bearing damage

4. Under voltage

1. Turn down discharge valve

2. Check and eliminate

3. Change

4. Voltage stabilization

Pump leaking

1. The connecting bolt looseness

2. Seal wear

3. Pump body with sand holes or broken

4. Sealing surface is not flat

1. Tightening up

2. Change

3. Welding repair or replacement

4. Repair
