Vortex pump is used to suck water and physical and chemical properties similar to the water used in liquid, the use of liquid temperature not exceeding 80 ℃, commonly used in boiler feed water, in shipbuilding, textile, chemical, metallurgy, machinery manufacturing, aquaculture, fixed Fire regulator: heat exchange units, remote irrigation and other agricultural departments have a wide range of applications.
Vortex pump (also known as vortex pump) mainly by the impeller, pump and pump cover, belonging to the vane pump . The impeller is a disk, and the blades on the circumference are radially arranged uniformly; the annular flow passage is formed between the pump body and the impeller, the suction inlet and the discharge outlet are both located at the outer circumference of the impeller; This isolates the inlet and outlet.

Vortex pump common faults and solutions
malfunction | the reason | Solution |
| Pump no water after starting | 1. There is no liquid in the pump 2. Suction pipe leakage 3. Impeller and plumbing blocked 4. Pump turned wrong 5. Inhalation height exceeds the specified requirements (4-5m) | 1. Liquid pump to the tank 2. Eliminate air leaks 3. Check and clean the pipeline 4. Check and correct motor wiring 5. Reduce the geometry of the pump or reduce the length of the suction tube |
| Power is too high | 1. Indenter beyond the scope of use 2. Pump, pump cover and impeller clearance is too small | 1. Lower the pump head 2. Adjust the gap to the specified range |
| Leak seal too much | 1. Mechanical seal static ring and moving ring skew occurs 2. Rubber seal aging 3. Water contains solid impurities 4. Spring seals in mechanical seals | 1. Repair or change to meet the requirements 2. Replace the rubber seal 3. Install a qualified filter 4. Replace the spring |
| Reduced displacement | 1. Speed ​​reduced 2. Impeller or pipeline blockage 3. Pipeline resistance is greater than the specified value 4. Impeller and the pump, the gap between the pump cover is too large | 1. Increase speed to nominal value 2. Check and clean up debris, garbage 3. Check the pipe installation, try to reduce the elbow or valve 4. Adjust the gap |

Cause Solution No water after pump start 1. There is no liquid in the pump2. Suction pipe leakage
3. Impeller and plumbing blocked
4. Pump turned wrong
5. Inhalation height exceeds the specified requirements (4-5m) 1. Liquid pump to the tank
2. Eliminate air leaks
3. Check and clean the pipeline
4. Check and correct motor wiring
5. Reduce the pump geometry installation height or reduce the length of the suction pipe power is too large 1. Indenter beyond the scope of use
2. Pump, pump cover and impeller gap is too small 1. Lower the pump head
2. Adjust clearance to the specified range too much leakage seal 1. Mechanical seal static ring and moving ring skew occurs
2. Rubber seal aging
3. Water contains solid impurities
4. Spring loose in mechanical seal 1. Repair or change to meet the requirements
2. Replace the rubber seal
3. Install a qualified filter
4. Replacement spring displacement reduced by 1. Speed ​​reduced
