4. Konfigurazioa eta instalazioa
4.1 Desontziratzea eta ikuskatzea
- Carefully remove the pump from its packaging.
- Inspect the pump for any visible damage that may have occurred during transit.
- Egiaztatu ontziratze-zerrendan zerrendatutako osagai guztiak daudela.
4.2 Muntaketa
- The LPD type pump is designed for inline installation directly into the piping system.
- Ensure the mounting location is stable, level, and can support the weight of the pump and associated piping when filled with liquid.
- Allow sufficient space around the pump for ventilation and future maintenance access.
4.3 Piping Connections
- Connect the pump to the piping system, ensuring all connections are tight and leak-free.
- Use appropriate sealing materials for pipe threads.
- Ensure the piping is properly supported to prevent strain on the pump casing.
4.4 Konexio elektrikoak
- Connect the pump to a three-phase 200/220V power supply, matching the frequency of 50Hz.
- All electrical work must be performed by a qualified electrician in accordance with local codes.
- Ensure correct wiring for motor rotation.
5. Funtzionamendu-argibideak
5.1 Eragiketa aurreko egiaztapenak
- Confirm all piping connections are secure and there are no leaks.
- Ensure the pump casing is filled with the liquid to be pumped (priming).
- Check that the power supply matches the pump's requirements.
5.2 Ponpa martxan jartzea
- Open the discharge valve gradually after starting the pump.
- Monitor for unusual noises or vibrations. If detected, shut down immediately and investigate.
5.3 Ponpa gelditzea
- Close the discharge valve gradually.
- Itzali ponparen hornidura.
5.4 Likidoen Manipulazioa
This pump is designed to handle clean water within a temperature range of 0°C to 100°C. Do not use it for liquids outside this specification or for corrosive/abrasive fluids unless specifically approved by EBARA.
6. Mantentzea
Regular maintenance is crucial for the longevity and optimal performance of your EBARA pump. Always disconnect power before beginning any maintenance procedures.
6.1 Ohiko ikuskapena
- Check for leaks around the shaft seal and piping connections.
- Entzun zarata edo bibrazio ezohikoak funtzionatzen ari den bitartean.
- Monitor motor temperature.
6.2 Disassembly and Inspection (without removing piping)
A key feature of the LPD pump is the ability to disassemble and inspect internal components without detaching the pump from the main piping. Refer to the detailed exploded view diagram (not provided in this document, refer to official EBARA service manual) for specific steps. This typically involves:
- Shutting down the pump and isolating it from the power supply.
- Draining the pump casing.
- Removing the motor and impeller assembly from the casing while the casing remains inline.
- Inspecting the impeller, mechanical seal, and bearings for wear or damage.
- Replacing worn parts as necessary.
- Reassembling the pump, ensuring all seals are correctly seated.
6.3 Mechanical Seal Replacement
The pump uses a mechanical seal. If leaks persist from the shaft seal, the mechanical seal may need replacement. This is a precision component and should be handled with care. Consult a qualified technician for replacement if you are unfamiliar with the procedure.
