This series of fountain pump is a special fountain pump developed by our factory. The pump motor core is made of high quality cold rolled silicon steel, which makes the pump more efficient, has good magnetic conductivity, and does not produce heat when starting frequently. The two ends of the motor rotor are equipped with alloy copper sleeves with water as lubricant. Stainless steel bushings replace ball bearings, avoiding the problems of easy rust of ball bearings and burnout of motor due to lack of oil and wear. Most suitable for music fountain, all models can be used horizontally.

3, mae'r modur ar gau neu strwythur gwlyb llawn dŵr, cyn ei ddefnyddio rhaid i'r ceudod modur tanddwr fod yn llawn dŵr glân, i atal ffug llawn, ac yna tynhau'r chwistrelliad dŵr, bolltau rhyddhau aer, fel arall ni chaniateir defnyddio
4, rhaid i bwmp tanddwr gael ei foddi'n llwyr yn y dŵr, nid yw'r dyfnder deifio yn fwy na 70m, nid yw gwaelod y pwmp tanddwr o waelod y ffynnon yn llai na 3m.
5, dylai llif dŵr y ffynnon allu bodloni'r allbwn dŵr pwmp tanddwr a gweithrediad parhaus, dylid rheoli allbwn dŵr y pwmp tanddwr ar 0.7 - 1.2 gwaith y llif graddedig.
6, dylai'r ffynnon fod yn syth, ni all y pwmp tanddwr gael ei ddefnyddio na'i ddympio, dim ond defnydd fertigol.
7, rhaid i'r pwmp tanddwr gael ei gydweddu â'r cebl yn unol â'r gofynion, a'r ddyfais amddiffyn gorlwytho allanol.
8, mae'r pwmp wedi'i wahardd yn llym heb beiriant prawf no-load dŵr

⑤ Ar ôl i'r cebl plwm-allan gael ei gysylltu â'r switsh rheoli, mae'n gysylltiedig â'r cyflenwad pŵer tri cham.
(4) Pethau i'w nodi yn ystod y gosodiad:
1. Os canfyddir ffenomen jamio yn ystod y broses bwmpio, trowch neu tynnwch y bibell ddŵr i oresgyn y pwynt jamio. Os nad yw mesurau amrywiol yn gweithio o hyd, peidiwch â gorfodi'r pwmp i lawr er mwyn osgoi difrod i'r pwmp trydan tanddwr a'r ffynnon.
2. Yn ystod y gosodiad, dylid gosod pad rwber ar fflans pob pibell a'i dynhau'n gyfartal.
3. Pan fydd y pwmp dŵr yn cael ei ostwng i'r ffynnon, dylid ei osod yng nghanol pibell y ffynnon i atal y pwmp rhag rhedeg yn erbyn wal y ffynnon am amser hir, gan achosi'r pwmp i ddirgrynu a'r modur i ysgubo a llosgi .
4. Darganfyddwch ddyfnder y pwmp dŵr i waelod y ffynnon yn ôl amodau tywod a silt y ffynnon sy'n llifo. Peidiwch â chladdu'r pwmp yn y mwd. Yn gyffredinol, nid yw'r pellter o'r pwmp dŵr i waelod y ffynnon yn llai na 3 metr (gweler Ffigur 2).
5. Ni ddylai dyfnder mynediad dŵr y pwmp dŵr fod yn llai na 1-1.5 metr o lefel y dŵr deinamig i'r nod mewnfa dŵr (gweler Ffigur 2). Fel arall, gall y Bearings pwmp dŵr gael eu niweidio'n hawdd.
6. Ni all lifft y pwmp dŵr fod yn rhy isel. Fel arall, mae angen gosod falf giât ar bibell ddŵr y ffynnon i reoli llif y pwmp ar y pwynt llif graddedig i atal y modur rhag cael ei orlwytho a'i losgi oherwydd cyfraddau llif mawr.
7. Pan fydd y pwmp dŵr yn rhedeg, dylai'r allbwn dŵr fod yn barhaus a hyd yn oed, dylai'r presennol fod yn sefydlog (o dan amodau gwaith graddedig, yn gyffredinol dim mwy na 10% o'r cerrynt graddedig), ac ni ddylai fod unrhyw ddirgryniad na sŵn. Os oes unrhyw annormaledd, dylid stopio'r peiriant i ddarganfod yr achos a'i ddileu.
8. Wrth osod, rhowch sylw i osodiad y wifren sylfaen modur (gweler Ffigur 2). Pan fydd y bibell ddŵr yn bibell ddur, ei harwain o'r clamp pen ffynnon; pan fydd y bibell ddŵr yn bibell blastig, ei arwain o farc sylfaen y pwmp trydan.
After the installation of the underwater pump, the insulation resistance and three-phase continuity of the switch face should be rechecked, and the connection between the instrument and the start device should be checked for any errors. If there is no problem, you can start to test the machine. After the start, observe whether the indication readings of each instrument are correct. If the rated voltage and current specified on the nameplate are exceeded, observe whether the pump has noise or vibration. If everything is normal, it can be put into operation. After the first operation of the pump for four hours, the motor should be shut down and tested for thermal insulation resistance quickly. Its value should not be less than 0.5 megaohm. After stopping the pump, it should be restarted after an interval of five minutes to prevent the water column in the pipeline from completely reversing and causing the motor to burn out due to excessive current. After the pump is put into normal operation, in order to prolong its service life, it is necessary to check regularly whether the supply voltage, running current and insulation resistance are normal. If the following conditions are found, the machine should be shut down immediately to eliminate the fault: the current exceeds 20% under rated working conditions; the dynamic water level drops to the inlet section, resulting in intermittent drainage; the underwater pump becomes violently vibrating or making noise; the supply voltage is lower than 340 volts; a fuse is blown out; the water pipe is damaged; the motor's thermal insulation resistance to the earth is less than 0.5 megaohm. The sequence of disassembly is: untie the cable fastening, remove the pipeline part, remove the line protection plate, screw down the water discharge bolt and discharge all the water in the motor chamber, remove the filter and loosen the coupling fixing screw of the motor shaft. The sequence of disassembly of the pump is: (see Figure 1) inlet section, impeller, guide housing, impeller, check the valve body. When removing the impeller, use special tools to loosen the taper sleeve of the impeller. Avoid bending the pump shaft and damaging the components throughout the process. The disassembly process of the motor is: (see Figure 1) put the motor on the platform, and remove the bolts, base, shaft head lock nut, thrust plate, key, lower guide plate (transverse bolt), bearing seat, screw knife seat from the bottom of the motor in order (take care not to damage the winding), and finally remove the connecting part and the upper guide bearing seat. Before assembling the unit, the rust and dirt of each part should be cleaned, and the sealant should be applied to each mating surface and fastener, and then assembled in reverse order of disassembly (the movement of the motor shaft after assembly is about one millimeter). After assembly, the coupling should be rotated flexibly and put on the filter for test. Once a year, or if less than a year of operation but has been immersed for two years, the underwater electric pump must be disassembled for maintenance in accordance with Article 5 and replace worn parts to ensure the normal operation and durability of the pump.
