Figure 2: Internal Diagram of the Centrifugal Pump. This diagram illustrates the key internal components of the pump, showing the flow path and mechanical parts.
- 1. Pump Casing: The outer housing of the pump, typically made of cast iron, which contains the impeller and directs the fluid flow.
- 2. Discharge Port: The outlet through which the pumped fluid exits the pump.
- 3. Impeller: The rotating component with vanes that imparts kinetic energy to the fluid, increasing its velocity and pressure.
- 4. Motor Shaft: The rotating shaft that connects the motor to the impeller, transmitting power.
- 5. Mechanical Seal: Prevents fluid leakage along the motor shaft where it enters the pump casing.
- 6. Bearings: Support the rotating shaft, reducing friction and ensuring smooth operation.
- 7. Motor Stator: The stationary part of the electric motor that contains the windings, generating the magnetic field.
- 8. Motor Rotor: The rotating part of the electric motor, connected to the shaft, which interacts with the stator's magnetic field to produce torque.
4. Opsætning og installation
4.1 Udpakning og inspektion
- Tag forsigtigt pumpen ud af emballagen.
- Inspect the pump for any visible damage that may have occurred during shipping. Report any damage to your supplier immediately.
- Sørg for, at alle komponenter, der er anført på pakkelisten, er til stede.
4.2 Montering af pumpen
- Select a dry, well-ventilated location, protected from direct sunlight and freezing temperatures.
- Mount the pump on a solid, level foundation to minimize vibration and noise. Use appropriate bolts to secure the pump through its base plate holes.
- Ensure there is sufficient space around the pump for ventilation and future maintenance.
4.3 VVS-tilslutninger
- Connect the suction pipe to the pump's inlet (1 1/4 inch) and the discharge pipe to the outlet (1 inch).
- Use appropriate pipe thread sealant on all connections to prevent leaks.
- Ensure that the piping is adequately supported to prevent strain on the pump connections.
- Install a foot valve with a strainer at the end of the suction pipe if drawing water from a well or tank.
4.4 Elektrisk tilslutning
- Sørg for, at strømforsyningen passer til pumpens volumentage requirements (230 VAC).
- Connect the pump to a dedicated, properly grounded electrical circuit protected by a circuit breaker or fuse.
- All electrical wiring should be performed by a qualified electrician in accordance with local electrical codes.
5. Betjening
5.1 Spædning af pumpen
Before initial start-up or after the pump has been drained, it must be primed.
- Remove the priming plug (if present) or open a valve on the discharge side.
- Fyld pumpen casinhelt med vand, indtil det løber over.
- Replace the priming plug or close the valve.
5.2 Start af pumpen
- Ensure the pump is properly primed.
- Åbn alle nødvendige ventiler på suge- og udløbsledningerne.
- Tænd for strømforsyningen til pumpen. Pumpen bør starte med det samme.
- Monitor the pump for unusual noises or vibrations during the first few minutes of operation.
5.3 Slukning af pumpen
- Sluk for strømforsyningen til pumpen.
- Close any necessary valves on the suction and discharge lines to prevent backflow.
6. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer pumpens levetid og optimale ydeevne.
6.1 Routine Checks (Weekly/Monthly)
- Check for any leaks around the pump casing or pipe connections.
- Listen for unusual noises or vibrations during operation.
- Undersøg netledningen for skader.
- Ensure the pump is adequately ventilated and free from debris.
6.2 Rengøring
- Periodically clean the exterior of the pump to prevent dirt buildup.
- If the pump is used with dirty water, regularly check and clean the strainer on the suction line.
6.3 Vinterklargøring/opbevaring
- If the pump will not be used for an extended period or in freezing temperatures, drain all water from the pump casing and pipes to prevent damage from ice expansion.
- Store the pump in a dry, protected area.
7. Fejlfinding
Se tabellen nedenfor for almindelige problemer og deres mulige løsninger.
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Pumpen starter ikke | No power; tripped circuit breaker; faulty motor. | Check power supply; reset breaker; consult a qualified technician. |
| Pumpen kører, men der kommer ikke noget vand | Pump not primed; air leak in suction line; clogged suction strainer; low water level. | Prime the pump; check all suction connections for leaks; clean strainer; ensure adequate water supply. |
