- Head up to 56 meters
- Robust construction for reliable performance
- 연속 사용을 위한 설계
4. 설정 및 설치
4.1. 위치
Choose a location that is dry, frost-free, and well-ventilated. The pump should be installed as close as possible to the water source to minimize suction lift. Ensure adequate space around the pump for ventilation and maintenance.
4.2. 장착
Securely mount the pump to a solid, level surface using appropriate bolts to prevent vibration and movement during operation.
4.3. 배관 연결
- Use pipes of adequate diameter to minimize friction losses.
- Install a foot valve with a strainer at the end of the suction line to prevent debris entry and maintain prime.
- Ensure all connections are airtight to prevent air leaks, which can cause loss of prime.
- Install a check valve on the discharge line if the pump is operating against a significant head or if backflow is a concern.
4.4. 전기적 연결
The pump operates on 230 Volts. Ensure your electrical supply matches this requirement. Connect the pump to a dedicated circuit protected by a residual current device (RCD) and an appropriately sized circuit breaker. All electrical wiring must comply with local codes and regulations.
4.5. 펌프 프라이밍
Before the first start-up, or if the pump has run dry, it must be primed. Remove the priming plug (often a red cap or brass plug) on the top of the pump casing and fill the pump body completely with clean water until it overflows. Replace the plug securely.
5. 사용 설명서
5.1. 초기 시작
- Ensure the pump is properly primed.
- Open any necessary valves on the suction and discharge lines.
- 펌프의 전원을 켭니다.
- The pump should start and begin pumping water. Monitor for unusual noises or vibrations.
5.2. 정상 작동
Allow the pump to run continuously within its specified operating range. Avoid frequent on/off cycling, which can reduce motor life. Regularly check for leaks and ensure adequate water supply.
5.3. 종료
To stop the pump, simply switch off the power supply. If the pump will be out of use for an extended period, especially in freezing conditions, drain the pump completely to prevent damage.
6. 유지관리
정기적인 유지관리는 펌프의 수명과 최적의 성능을 보장합니다.
- 정기 점검: Periodically inspect the pump for leaks, unusual noises, or excessive vibration. Check electrical connections for signs of wear or corrosion.
- 청소: 모터의 적절한 냉각을 위해 펌프 외부를 깨끗하게 유지하고 먼지와 이물질이 없도록 하십시오.
- 겨울철 : In areas subject to freezing temperatures, the pump must be completely drained to prevent ice damage. Disconnect power, open drain plugs, and remove the priming plug to allow all water to escape. Store the pump in a warm, dry place if possible.
- Impeller/Seal Inspection: If performance degrades, the impeller or mechanical seal may require inspection or replacement. This should be performed by a qualified technician.
