3. 설정 및 설치
Proper installation is crucial for the performance and longevity of your centrifuge. Refer to the image below for visual reference of the product.
그림 3.1: Lowara Multistage Horizontal Centrifuge, Model 2HM4 / A HP 0.6. This image shows the complete pump unit, featuring a blue motor housing on the right and a shiny, chrome-like pump body on the left. The pump body has an inlet connection at the front and an outlet connection on top. The unit is mounted on a sturdy blue base.
3.1 풀기 및 검사
Carefully remove the unit from its packaging. Inspect for any visible damage that may have occurred during transit. Report any damage to your supplier immediately.
3.2 배치
Install the pump on a firm, level, and stable surface capable of supporting its weight when full of fluid. Ensure the location is dry, well-ventilated, and protected from extreme temperatures, direct sunlight, and frost. Allow sufficient space around the unit for ventilation and future maintenance.
3.3 배관 연결
Connect the suction and discharge pipes to the pump's inlet and outlet ports. Use appropriate fittings and sealants to ensure leak-free connections. Avoid putting strain on the pump's ports by supporting the piping independently. Ensure the suction line is as short and straight as possible and free from air pockets.
3.4 전기 연결
Before connecting to the power supply, verify that the voltage and frequency match the specifications on the pump's nameplate. Connect the unit to a properly grounded electrical circuit with appropriate overcurrent protection. All wiring must comply with local electrical codes.
3.5 펌프 프라이밍
Before initial startup, the pump must be primed. Remove the priming plug (if present) or fill the pump casing through the discharge port until the pump body is completely filled with the liquid to be pumped. Replace the plug securely. This step is critical to prevent dry running and damage to the pump.
4. 사용 설명서
4.1 초기 시동
After ensuring the pump is properly primed and all connections are secure, switch on the power supply. The pump should start smoothly. Monitor for unusual noises, vibrations, or leaks during the first few minutes of operation.
4.2 정상 작동
Allow the pump to run within its specified operating range. Avoid continuous dry running, as this can cause severe damage to the mechanical seal and other components. Periodically check system pressure and flow rates to ensure optimal performance.
4.3 종료
To stop the pump, simply switch off the power supply. For extended periods of non-use, especially in freezing conditions, drain the pump and piping to prevent damage from ice expansion.
5. 유지관리
Regular maintenance ensures the longevity and efficiency of your Lowara centrifuge.
- 정기 점검: Regularly inspect the pump for leaks, unusual noises, excessive vibration, or overheating. Address any issues promptly.
- 청소: Keep the exterior of the pump clean, especially the motor's cooling fins, to ensure proper heat dissipation.
- 겨울철 : If the pump is installed in an area subject to freezing temperatures, drain all water from the pump and associated piping to prevent frost damage.
- 전문적인 서비스: For internal repairs or replacement of wear parts (e.g., mechanical seals, bearings), it is recommended to contact a qualified service technician or the manufacturer's authorized service center.
6. 문제 해결
This section outlines common issues and their potential solutions. Always disconnect power before attempting any troubleshooting or repair.
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| 펌프가 시작되지 않습니다 | 정전; 차단기 작동; 모터 고장. | 전원 공급 장치를 점검하고, 차단기를 재설정하고, 전기 기술자에게 문의하십시오. |
| Pump runs but no water/low flow | Pump not primed; air in suction line; clogged impeller/pipes; suction lift too high. | Re-prime pump; check for air leaks; clear obstructions; reduce suction lift. |
| 과도한 소음 또는 진동 | Cavitation; worn bearings; misaligned coupling; loose mounting. | Check suction conditions; inspect bearings; ensure proper alignment and mounting. |
| 펌프에서 누수 | Damaged mechanical seal; loose pipe connections. | Inspect/replace mechanical seal; tighten connections. |
