Figure 1: Pedrollo PLURIJET M4/80-N Self-Priming Multi-Stage Water Pump. This image shows the overall design of the pump, highlighting its compact and robust construction.
2. 기술적 특성
- Completely renewed range with a new design.
- Improved hydraulic performance for higher efficiency.
- 에너지 소비량 감소.
- One of the quietest models in the centrifugal pump series.
- Enhanced priming capabilities.
3. 설치 및 사용
The PLURIJET pumps are suitable for use with clean water, even when air is present, and with liquids that are not chemically aggressive towards the materials from which the pump is made. Due to their quietness, reliability, and low energy consumption, they are recommended for domestic and civil applications such as water supply systems, pressure boosting, and irrigation.
3.1. Application Limits
- Liquid temperature: from -10 °C to +40 °C
- Ambient temperature: up to +40 °C
- Manometric suction lift: up to 9 m (HS)
- 최대 작동 압력 : 6bar
- Continuous service: S1
4. 설정
Proper setup is crucial for optimal performance and longevity of the pump. Ensure the pump is installed in a dry, well-ventilated area, protected from direct sunlight and frost.
4.1. 전기적 연결
Connect the pump to a single-phase 230 V, 50 Hz power supply. Ensure the electrical installation complies with local regulations and safety standards. The power cable is not included and must be appropriately sized for the pump's power requirements (0.55 kW / 0.75 HP).
4.2. 유압 연결
Connect the suction and delivery pipes to the pump's threaded ports. Ensure all connections are watertight to prevent air ingress, which can affect priming and pump performance. Use appropriate sealants and fittings.
4.3. 펌프 프라이밍
Before first use, or after any period of disuse, the pump must be primed. Fill the pump body completely with clean water through the dedicated filling port until water overflows. Close the filling port securely before starting the pump.
5. 사용 설명서
Once installed and primed, the pump is ready for operation. Ensure the suction line is submerged in water and free from obstructions.
5.1. 펌프 시동
Switch on the power supply to the pump. The pump will begin to draw water. Monitor the pressure gauge (if installed) to ensure proper operation. The pump is designed for continuous service (S1).
5.2. Stopping the Pump
To stop the pump, switch off the power supply. For prolonged periods of disuse, especially in freezing conditions, drain the pump completely to prevent damage.
6. 유지관리
Regular maintenance ensures the longevity and efficient operation of your Pedrollo pump.
6.1. 정기 점검
- Periodically check for leaks around connections.
- Ensure the pump is free from excessive vibration or unusual noises.
- Verify that the ventilation openings on the motor are clear.
6.2. 동절기 준비
In areas subject to freezing temperatures, drain the pump and associated piping completely to prevent damage from ice expansion. Store the pump in a dry, frost-free location if possible.
7. 문제 해결
이 섹션에서는 펌프 사용 중 발생할 수 있는 일반적인 문제에 대한 해결책을 제공합니다.
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| 펌프가 시작되지 않습니다 | No power supply, motor overload, seized impeller | Check power connection and circuit breaker. Allow motor to cool. Inspect impeller for obstructions. |
| 펌프가 작동하지만 물을 공급하지 않음 | Pump not primed, air leak in suction line, suction lift too high, clogged suction filter | Re-prime the pump. Check all suction connections for leaks. Verify suction lift is within limits. Clean suction filter. |
| 유량 또는 압력 감소 | Partial blockage, worn impeller, air in system | Check for blockages in pipes. Inspect impeller for wear. Bleed air from the system. |
| 과도한 소음 또는 진동 | Cavitation, foreign object in pump, worn bearings | Ensure adequate water supply to prevent cavitation. Inspect pump for foreign objects. Contact service for bearing replacement. |
