6. Angkat pompa banyu ora bisa sithik banget. Yen ora, katup gapura kudu dipasang ing pipa banyu sumur kanggo ngontrol aliran pompa ing titik aliran sing dirating kanggo nyegah motor kakehan lan kobong amarga tingkat aliran gedhe.
7. Nalika pompa banyu mlaku, output banyu kudu terus-terusan lan malah, arus kudu stabil (ing kondisi kerja sing dirating, umume ora luwih saka 10% saka arus sing dirating), lan ora ana getaran utawa gangguan. Yen ana kelainan, mesin kudu mandheg kanggo ngerteni sababe lan ngilangi.
8. Nalika nginstal, mbayar manungsa waé menyang setelan saka kabel grounding motor (ndeleng Figure 2). Nalika pipa banyu minangka pipa baja, mimpin saka clamp wellhead; nalika pipa banyu minangka pipa plastik, mimpin saka tandha grounding pompa listrik.

1. (1)After the submersible pump is installed, check the insulation resistance and three-phase conduction from the switch again, check whether the instrument and the connection of the start equipment are wrong, if there is no problem, the trial machine can be started, and observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate after the start, and observe whether the pump has noise and vibration phenomenon, and put into operation if everything is normal.
2. (2)After the first operation of the pump for four hours, the motor should be shut down to test the thermal insulation resistance quickly, and its value should not be less than 0.5 megaohm.
3. (3)After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from being completely reflowed and causing excessive motor current and burnout.
4. (4)After the pump is put into normal operation, in order to prolong its service life, it is necessary to check whether the supply voltage, working current and insulation resistance are normal regularly. If the following conditions are found, the pump should be shut down immediately to troubleshoot.

1 In the rated condition, the current exceeds 20%.

 2 Tingkat banyu dinamis mudhun menyang bagean mlebu banyu, nyebabake banyu intermiten.

 3 Pompa submersible duwe geter utawa swara sing abot.

 4 Tegangan suplai luwih murah tinimbang 340 volt.

 5 Sekring mati.

 6 Pipa pasokan banyu rusak.

 7 The motor's thermal insulation resistance is lower than 0.5 megaohm.

5.  
6. (5)Unit disassembly:

 1 Untie the cable tie, remove the pipeline part, and remove the wire plate.

 2 meneng mudhun bolt banyu, sijine banyu ing kamar motor.

 3 mbusak Filter, ngeculke meneng tetep ing kopling kanggo ndandani batang motor.

 4 meneng mudhun bolt nyambungake bagean welingan banyu karo motor, lan misahake kumpa saka motor (mbayar manungsa waé kanggo bantal unit nalika misahake, kanggo nyegah mlengkung saka batang pump)

 5 urutan pembongkaran pompa yaiku: (pirsani gambar 1) bagean inlet banyu, impeller, cangkang pangalihan, impeller...... mriksa awak tutup, nalika njabut impeller, gunakake alat khusus kanggo ngeculake lengen kerucut sing tetep. impeller pisanan, lan supaya mlengkung lan bruising batang pump ing proses disassembly.

 6 proses disassembly motor punika: (ndeleng tokoh 1) nyeleh motor ing platform, lan copot perkakas, basa, nut ngunci sirah poros, piring tikaman, tombol, jog prewangan guide ngisor lan bolt sirah pindho saka ngisor. motor ing siji, lan banjur njupuk metu rotor (pay manungsa waé ora kanggo ngrusak paket kabel) lan pungkasanipun mbusak bagean nyambungake lan guide ndhuwur prewangan jog.

 7 unit perakitan: sadurunge perakitan, teyeng lan rereget saka bagean kudu di resiki, lan lumahing kawin lan fasteners ditutupi karo sealant, lan banjur nglumpuk ing urutan ngelawan saka disassembly (poros motor gerakane munggah lan mudhun sawise perakitan kanggo bab siji. millimeter), sawise perakitan, kopling kudu fleksibel, banjur mesin tes layar Filter. Pompa submersible kudu dijupuk metu saka sumur kanggo dismantling lan pangopènan miturut Artikel 5 sawise taun operasi, utawa kurang saka setahun operasi nanging rong taun wektu nyilem, lan bagean worn bakal diganti.

In order to ensure long-term use of your submersible pump, we strongly recommend that you drain the water in all motor cavities especially in winter to prevent the motor from freezing; at the same time, roll up the cable and tie it well. Store the equipment in a room without corrosive substances and gases, with the temperature below 40 °C. In addition, if you do not use the submersible pump for a long time, be sure to pay attention to rust prevention measures. These simple steps will help you maintain the performance of the equipment and extend its service life.
