2. Pandan enstalasyon, yo ta dwe mete yon pad kawotchou nan bride chak tiyo epi sere boulon respire.
3. Lè ponp dlo a bese nan pi a, li ta dwe mete l nan mitan tiyo a pou anpeche ponp lan kouri kont miray la byen pou yon tan long, sa ki lakòz ponp lan vibre ak motè a bale ak boule. .
4. Detèmine pwofondè ponp dlo a nan fon pi a dapre sab koule ak kondisyon limon nan pi a. Pa antere ponp lan nan labou. Distans ki soti nan ponp dlo a nan anba a nan pi a se jeneralman pa mwens pase 3 mèt (gade Figi 2).
5. Pwofondè dlo a antre nan ponp dlo a ta dwe pa mwens pase 1-1.5 mèt soti nan nivo dlo dinamik nan ne inlet dlo a (gade Figi 2). Sinon, bi ponp dlo yo ka fasil domaje.
6. Leve ponp dlo a pa ka twò ba. Sinon, yon tiyo pòtay bezwen yo dwe enstale sou tiyo dlo a pou kontwole koule ponp lan nan pwen an koule rated pou anpeche motè a twò chaje ak boule akòz gwo pousantaj koule.
7. Lè ponp dlo a ap kouri, pwodiksyon dlo a ta dwe kontinyèl e menm, aktyèl la ta dwe estab (anba kondisyon travay rated, jeneralman pa plis pase 10% aktyèl la nominal), epi pa ta dwe gen okenn vibrasyon oswa bri. Si gen nenpòt anòmal, yo ta dwe sispann machin nan pou chèche konnen kòz la epi elimine li.
8. Lè w ap enstale, peye atansyon sou anviwònman fil motè a (gade Figi 2). Lè tiyo dlo a se yon tiyo asye, mennen li soti nan kranpon nan wellhead; lè tiyo dlo a se yon tiyo plastik, mennen li soti nan mak baz la nan ponp elektrik la.

• （1）With the continuous development of modern technology, submersible pumps play a crucial role in the field of pumps. After installing the submersible pump, check the insulation resistance and three-phase continuity repeatedly to ensure that there are no errors in the connection between the instrument and the starting equipment. If everything is normal, the test equipment can be started. After starting, observe whether the indication readings of each instrument are correct. If the rated voltage and current specified on the nameplate are exceeded, pay attention to observe whether the pump has any noise or vibration. If everything is normal, it can be put into operation. After the pump runs for four hours for the first time, it should be closed and the thermal insulation resistance of the motor should be tested quickly, and its value should not be less than 0.5 megaohms. After stopping the pump, restart it after five minutes to prevent the water column in the pipeline from completely reversing, resulting in the motor burning due to overcurrent. After the pump is running normally, in order to prolong its service life, it is necessary to check regularly whether the supply voltage, working current and insulation resistance are normal. If the following conditions are found, the equipment should be shut down immediately to troubleshoot. The current exceeds 20% under the rated working conditions; the dynamic water level drops to the inlet section, resulting in intermittent drainage; the submersible pump vibrates violently or makes noisy sounds; the supply voltage is lower than 340 volts; any fuse is broken; the water pipe is damaged; The thermal insulation resistance between the motor and the ground is less than 0.5 megaohm.These recommended operating procedures and safety measures ensure the safe operation of the submersible pump, prolong the service life of the equipment, and provide users with a reliable pump choice.
•  
• （2）Unit disassembly:
• 1 untie the cable tie, remove the pipeline part, remove the wire plate.
• 2 unscrew the water release bolt, put the water in the motor chamber.
• 3 remove the filter, loose the fixing screw of the motor shaft on the coupling.
• 4 unscrew the bolt connecting the water inlet section with the motor, and separate the pump from the motor (pay attention to the unit cushion when separating, to prevent the bending of the pump shaft)
• 5 the disassembly sequence of the pump is: (see figure 1) water inlet section, impeller, diversion shell, impeller...... check valve body, when removing the impeller, use special tools to loosen the conical sleeve of the fixed impeller first, and avoid bending the pump shaft and various bumps in the disassembly process.
• 6 the disassembly process of the motor is: (see figure 1) place the motor on the platform, and remove the nut, base, shaft head lock nut, thrust plate, key, lower guide bearing seat, double head bolt from the bottom of the motor in turn. Then take out the rotor (pay attention not to damage the wire package) and finally remove the connecting section and upper guide bearing seat.
• 7 unit assembly: Before assembly, the rust and dirt of the parts should be cleaned, and the mating surfaces and fasteners should be coated with sealant. Then they should be assembled in the reverse order of disassembly (the up and down momentum of the motor shaft is about 1 mm after assembly). After assembly, the coupling should be flexible, and then the filter screen test machine.
•  
• （3）The submersible pump should be dismantled and repaired according to Article 5 for each operation year, or less than one year, but the submersible time has reached two years, and the worn parts should be replaced.

 1, mete dlo a nan kavite motè a (sitou nan sezon fredi pou anpeche motè a konjel), epi mare kab la byen.
