5. Instalacija (Podešavanje)
Proper installation is critical for the pump's performance and longevity. Follow these guidelines carefully.
Slika 3: Prample 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.
- Lokacija: Install the pump in a dry, well-ventilated area, protected from direct sunlight, rain, and freezing temperatures. Ensure sufficient space for maintenance.
- Montaža: Securely mount the pump on a stable, level surface using appropriate bolts to minimize vibration.
- Usisni vod:
- 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.
- Ispusna linija: Connect the discharge pipe to the pump's outlet. Install a gate valve on the discharge side to regulate flow and facilitate maintenance.
- Električni priključak:
- 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.
- Sve električne priključke mora izvršiti kvalificirani električar u skladu s lokalnim propisima.
- Prajming: Before first use, fill the pump casing completely with clean water through the priming port until it overflows. Replace the priming plug securely.
6. Operacija
Once installed and primed, the pump is ready for operation.
- Pokretanje pumpe:
- Ensure the pump is fully primed.
- Open the discharge valve partially or fully.
- Switch on the power supply to the pump. The pump should start immediately and begin pumping water.
- Nadgledanje: Observe the pump during operation for any unusual noises, vibrations, or leaks.
- Zaustavljanje pumpe:
- Zatvorite ispusni ventil.
- Switch off the power supply to the pump.
- Kontinuirani rad: The pump is designed for continuous S1 service, meaning it can operate continuously under a constant load.
7. Karakteristike performansi
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. Održavanje
Regular maintenance ensures optimal performance and extends the pump's lifespan. Always disconnect power before maintenance.
- Redovne provjere:
- Inspect the pump and piping for leaks.
- Check electrical connections for signs of wear or corrosion.
- Osluškujte neobične zvukove tokom rada.
- čišćenje: Periodically clean the pump's exterior to prevent dust and debris buildup, which can affect cooling.
- Nožni ventil/filter: Regularly inspect and clean the foot valve strainer to prevent blockages and ensure proper water intake.
- Zimljenje: Ako je pumpa izložena temperaturama smrzavanja, ispustite svu vodu iz pumpe casing and piping to prevent damage from ice expansion.
- Mehanička brtva: The mechanical seal is a wear part. If persistent leaks occur from the shaft area, the seal may need replacement by a qualified technician.
