250QJP Pompa Sommersibbli Peep Well

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. Pompi b'ras ta 'aktar minn 30 metru jużaw pajpijiet ta' l-azzar, u s-sekwenza ta 'installazzjoni hija kif ġej:
①Uża morsa biex tikklampja t-tarf ta 'fuq tal-parti tal-pompa ta' l-ilma (il-mutur u l-pompa ta 'l-ilma ġew imqabbda f'dan il-ħin), erfaha b'katina mdendla, u orbotha bil-mod fil-bir sakemm Poġġi l-morsa fuq ir-ras u neħħi l- katina mdendlin.
② Uża par klampi ieħor biex tikklampja pajp, erfah b'katina mdendla 15 ċm 'il bogħod mill-flanġ, u niżżlu bil-mod. Bejn il-flanġ tal-pajp u l-flanġ tal-pompa Poġġi l-kuxxinett tal-gomma f'postu u issikka l-pajp u l-pompa b'mod uniformi b'boltijiet, ġewż u woxers tar-rebbiegħa.
③ Neħħi ftit il-pompa sommerġibbli, neħħi l-morsa fuq it-tarf ta 'fuq tal-pompa ta' l-ilma, torbot il-kejbil sew mal-pajp ta 'l-ilma b'tejp tal-plastik, u orbotha bil-mod sakemm Il-morsa titqiegħed fil-bir.
④Uża l-istess metodu biex torbot il-pajpijiet tal-ilma kollha fil-bir.
⑤Wara li l-kejbil tal-ħruġ ikun imqabbad mal-iswiċċ tal-kontroll, huwa konness mal-provvista tal-enerġija bi tliet fażijiet.

(4) Affarijiet li għandek tinnota waqt l-installazzjoni:
1. Jekk jinstab fenomenu ta 'iġġammjar waqt il-proċess ta' l-ippumpjar, dawwar jew iġbed il-pajp ta 'l-ilma biex tegħleb il-punt ta' iġġamjar. Jekk il-miżuri varji għadhom ma jaħdmux, jekk jogħġbokMa jġiegħelx il-pompa 'l isfel biex tevita ħsara lill-pompa elettrika sommerġibbli u l-bir.
2. Waqt l-installazzjoni, kuxxinett tal-gomma għandu jitqiegħed fil-ħanek ta 'kull pajp u ssikkat indaqs.
3. Meta l-pompa tal-ilma titbaxxa fil-bir, għandha titqiegħed fin-nofs tal-pajp tal-bir biex tevita li l-pompa taħdem kontra l-ħajt tal-bir għal żmien twil, u tikkawża li l-pompa tivvibra u l-mutur jiknes u jinħaraq .
4. Iddetermina l-fond tal-pompa ta 'l-ilma sal-qiegħ tal-bir skond il-kundizzjonijiet ta' ramel u ħama li jirriżultaw tal-bir. Tidfenx il-pompa fit-tajn. Id-distanza mill-pompa tal-ilma sal-qiegħ tal-bir hija ġeneralment mhux inqas minn 3 metri (ara Figura 2).
5. Il-fond tad-dħul ta 'l-ilma tal-pompa ta' l-ilma m'għandux ikun inqas minn 1-1.5 metri mil-livell dinamiku ta 'l-ilma għan-nodu tad-dħul ta' l-ilma (ara l-Figura 2). Inkella, il-bearings tal-pompa tal-ilma jistgħu jiġu mħassra faċilment.
6. Il-lift tal-pompa tal-ilma ma jistax ikun baxx wisq. Inkella, valv gate jeħtieġ li jiġi installat fuq il-pipeline ta 'l-ilma tar-ras biex jikkontrolla l-fluss tal-pompa fil-punt tal-fluss nominali biex jipprevjeni li l-mutur jiġi mgħobbi żżejjed u jinħaraq minħabba rati ta' fluss kbar.
7. Meta l-pompa ta 'l-ilma tkun qed taħdem, l-output ta' l-ilma għandu jkun kontinwu u saħansitra, il-kurrent għandu jkun stabbli (taħt kundizzjonijiet tax-xogħol ratati, ġeneralment mhux aktar minn 10% tal-kurrent nominali), u m'għandux ikun hemm vibrazzjoni jew storbju. Jekk ikun hemm xi anormalità, il-magna għandha titwaqqaf biex issir taf il-kawża u teliminaha.
8. Meta tinstalla, oqgħod attent għall-issettjar tal-wajer tal-ert tal-mutur (ara l-Figura 2). Meta l-pajp ta 'l-ilma jkun pajp ta' l-azzar, wassalha mill-morsa tal-ħofor; meta l-pajp ta 'l-ilma huwa pajp tal-plastik, wassalha mill-marka ta' l-ert tal-pompa elettrika.

 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.
