4. ການຕິດຕັ້ງ
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 ການເຊື່ອມຕໍ່ໄຟຟ້າ
- 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.
- ໃຫ້ແນ່ໃຈວ່າການສະຫນອງພະລັງງານກົງກັບ vol ຂອງປັ໊ມtage ແລະການຈັດອັນດັບຄວາມຖີ່.
- 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. ຕັ້ງຄ່າ
- Priming the Pump: 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.
- ກວດສອບການຮົ່ວໄຫລ: After filling, inspect all connections for any leaks.
- ກວດສອບພະລັງງານ: 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. ຄໍາແນະນໍາການດໍາເນີນງານ
- ເລີ່ມ Pump ໄດ້: 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.
- ການຕິດຕາມ: During operation, monitor for unusual noises, excessive vibration, or leaks. Ensure the pump is delivering water at the expected flow and pressure.
- ການຢຸດປັ໊ມ: Close the discharge valve, then switch off the power.
- ການປິດຂະຫຍາຍການ: 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.
