4. Орнотуу
4.1 Mechanical Installation (Plumbing)
- Mount the pump on a solid, level surface to minimize vibration.
- Ensure the pump is installed in a dry, well-ventilated area, protected from direct sunlight and adverse weather conditions.
- Use pipes of adequate diameter to avoid excessive pressure drops. The inlet and outlet connections are 1 inch.
- Install a foot valve with a strainer on the suction line to prevent debris from entering the pump and to maintain prime.
- Ensure all pipe connections are airtight to prevent air leaks, which can affect pump performance.
- Install isolation valves on both suction and discharge lines for easier maintenance.
4.2 Электрдик туташуу
- The pump requires a three-phase 400V, 50Hz power supply.
- Electrical connections must be performed by a qualified electrician in compliance with local electrical codes.
- Электр энергиясы насостун көлөмүнө дал келүүсүн текшериңизtage жана жыштык рейтингдери.
- Install appropriate circuit breakers or fuses for motor protection.
- Connect the pump to a properly grounded electrical system.
- Verify the motor's rotation direction. If incorrect, reverse two of the phase wires.

5. Орнотуу
- Насосту толтуруу: Before initial startup, completely fill the pump casing and the suction line with clean water through the priming port. This is crucial to prevent dry running.
- Агышууларды текшерүү: After filling, inspect all connections for any leaks.
- Кубат текшерүү: Briefly turn on the power to check the motor's rotation direction. If the rotation is incorrect (e.g., indicated by a label or arrow on the motor), immediately turn off the power and reverse two of the phase wires.
6. Иштөө нускамалары
- Насосту ишке киргизүү: Ensure the pump is fully primed. Open the discharge valve slightly, then switch on the power. Gradually open the discharge valve completely once the pump is running smoothly.
- Мониторинг: During operation, monitor for unusual noises, excessive vibration, or leaks. Ensure the pump is delivering water at the expected flow and pressure.
- Насосту токтотуу: Close the discharge valve, then switch off the power.
- Кеңейтилген өчүрүү: If the pump will be out of service for an extended period, especially in freezing conditions, drain all water from the pump and piping to prevent damage.
7. Техникалык тейлөө
Үзгүлтүксүз техникалык тейлөө насостун оптималдуу иштешин камсыз кылат жана анын иштөө мөөнөтүн узартат.
- Үзгүлтүксүз текшерүү: Periodically check for leaks, unusual noises, or vibrations.
- Тазалык: Keep the pump and motor free from dust and debris to ensure proper cooling.
- Foot Valve/Strainer: Inspect and clean the foot valve strainer regularly to prevent blockages.
- Кыштоо: In areas prone to freezing, drain the pump and associated piping completely or protect them from freezing temperatures.
- Кесиптик кызмат: For internal component inspection or replacement (e.g., seals, bearings), consult a qualified service technician.
