5. ການຕິດຕັ້ງ (Setup)
Proper installation is critical for the pump's performance and longevity. Follow these guidelines carefully.
ຮູບທີ 3: ຕົວຢ່າງample Installation Diagram. This illustration demonstrates a typical setup for the Pedrollo pump, showing the suction height (HS) and the placement of a non-return valve for optimal performance.
- ສະຖານທີ່: Install the pump in a dry, well-ventilated area, protected from direct sunlight, rain, and freezing temperatures. Ensure sufficient space for maintenance.
- ການຕິດຕັ້ງ: Securely mount the pump on a stable, level surface using appropriate bolts to minimize vibration.
- ສາຍດູດ:
- The pump is self-priming and recommended for drawing water from depths of less than 9 meters.
- Use a rigid, airtight suction pipe with a diameter equal to or larger than the pump's suction port.
- Install a foot valve with a strainer at the end of the suction pipe to prevent debris entry and maintain prime.
- Ensure the suction line slopes upwards towards the pump to avoid air pockets.
- ສາຍລະບາຍນ້ຳ: Connect the discharge pipe to the pump's outlet. Install a gate valve on the discharge side to regulate flow and facilitate maintenance.
- ການເຊື່ອມຕໍ່ໄຟຟ້າ:
- Connect the pump to a single-phase 220V power supply.
- Ensure the electrical circuit is protected by a suitable circuit breaker and residual current device (RCD).
- The motor has built-in thermal protection, but additional external protection is recommended for critical applications.
- All electrical connections must be performed by a qualified electrician in accordance with local regulations.
- ການແຕ່ງຕົວ: Before first use, fill the pump casing completely with clean water through the priming port until it overflows. Replace the priming plug securely.

7. ລັກສະນະການປະຕິບັດ
The performance of the Pedrollo JSWM3CM pump is characterized by its flow rate (Q) and total head (HMT). Refer to the performance curve diagram for detailed information.
Figure 4: Performance Curves for JSW3 Series Pumps. This graph illustrates the relationship between flow rate (Q) and total head (HMT) for various models within the JSW3 series, including the JSWM3CM, at 50 Hz and 2900 rpm.
The graph shows how the pump's head (pressure) decreases as the flow rate increases. Locate the curve corresponding to the JSWM3CM model to understand its specific operating range. The pump delivers a flow rate between 0 and 7.2 m³/h and a head between 20 and 54 meters, depending on the operating point.
8. ບໍາລຸງຮັກສາ
Regular maintenance ensures optimal performance and extends the pump's lifespan. Always disconnect power before maintenance.
