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.

(4) Saachen ze notéieren während der Installatioun:
1. Wann e Stau-Phänomen während dem Pompelprozess fonnt gëtt, dréit oder zitt d'Waasserleitung fir de Staupunkt ze iwwerwannen. Wann verschidde Moossnamen nach ëmmer net funktionnéieren, w.e.g. Kraaft d'Pompel net erof fir Schued un der Tauchtpompel an der Brunn ze vermeiden.
2. Bei der Installatioun sollt e Gummi-Pad am Flange vun all Päif plazéiert ginn a gläichméisseg festgehalen ginn.
3. Wann d'Waasserpompel an d'Wuel erofgesat gëtt, sollt et an der Mëtt vun der Brunnpipe plazéiert ginn, fir datt d'Pompel net laang géint d'Wuelmauer leeft, sou datt d'Pompel vibréiert an de Motor schëdden a brennt. .
4. Bestëmmt d'Tiefe vun der Waasserpompel bis zum Buedem vun der Brunn no de fléissende Sand a Siltbedingunge vun der Brunn. Begruewen d'Pompel net am Bulli. D'Distanz vun der Waasserpompel bis zum Enn vun der Brunn ass normalerweis net manner wéi 3 Meter (kuckt Figur 2).
5. D'Waasserentrée Tiefe vun der Waasserpompel sollt net manner wéi 1-1,5 Meter vum dynamesche Waasserniveau op d'Waasserinletknuet sinn (kuckt Figur 2). Soss kënnen d'Waasserpompellager liicht beschiedegt ginn.
6. De Lift vun der Waasserpompel kann net ze niddreg sinn. Soss muss e Paartventil op der Wellhead Waasserleitung installéiert ginn fir de Pompelstroum um bewäertte Flosspunkt ze kontrolléieren fir ze verhënneren datt de Motor iwwerlaascht a verbrannt gëtt wéinst grousse Flowraten.
7. Wann d'Waasserpompel leeft, soll d'Waasserausgang kontinuéierlech sinn a souguer, de Stroum soll stabil sinn (ënner bewäertte Aarbechtsbedingunge, allgemeng net méi wéi 10% vum bewäerten Stroum), an et sollt keng Schwéngung oder Kaméidi sinn. Wann et eng Anomalie ass, sollt d'Maschinn gestoppt ginn fir d'Ursaach erauszefannen an ze eliminéieren.
8. Beim Installatioun, oppassen op d'Astellung vum Motor Buedemdraad (kuckt Bild 2). Wann d'Waasser Päif e Stol Päif ass, féiert et aus der wellhead clamp; wann d'Waasserleitung e Plastiksleit ass, féiert se vun der Äerdmarke vun der elektrescher Pompel.
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.
