This well submersible pump is a pump suitable for clean water. Digging new wells and pumping sediment and turbid water are strictly prohibited. The voltage grade of the well pump is 380V/50HZ. Submersible motors with other voltage grades need to be customized. Underground cables must use waterproof cables and must be equipped with starting equipment, such as distribution boxes, etc. The starting equipment should have common comprehensive motor protection functions, such as overload short circuit protection, phase loss protection, undervoltage protection, grounding protection and idling protection, etc. In abnormal cases, the protection device should be tripped in time. During installation and use, the pump must be reliably grounded. It is prohibited to push and pull the switch when hands and feet are wet. The power supply must be cut off before installation and maintenance of the pump. The place where the pump is used must be set up with obvious "anti-electric shock" marks. Before going down the well or installation, the motor must be injected with distilled water or non-corrosive clear cold water in the inner cavity, and the intake/drain bolts must be tightened. When testing the pump on the ground, water must be injected into the pump chamber to lubricate the rubber bearings. The instant start time should not exceed one second to check whether the direction is correct. The same as the steering instructions. Pay attention to safety when the pump is upright to prevent tilting and injury. Strictly in accordance with the provisions of the pump lift and flow range, to prevent the pump flow at low lift or in high lift pull too large, resulting in extreme wear of thrust bearings and other components, the motor due to overload and burn. After put into the well, the measurement of the motor and the ground insulation resistance value, not less than 100M. After the start, regular observation of voltage and current, and check the motor winding insulation is in line with the requirements of the provisions. If the temperature of the storage site is below the freezing point, the water in the pump chamber should be drained to prevent the water in the motor chamber from freezing and damaging the motor due to low temperature.

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.After installing the submersible pump, recheck the insulation resistance and three-phase continuity switch, check whether there is any error in the connection between the instrument and the starting equipment.If there is no problem, you can start to test the machine. After starting, observe whether the indication reading of each instrument is correct.If the rated voltage and current specified on the nameplate are exceeded, please observe whether the pump has noise or vibration.If everything is normal, it can be put into operation. After the pump runs for the first time for four hours, the motor thermal insulation resistance should be closed and tested quickly. Its value should not be less than 0.5 megaohm. After the pump stops, it should be restarted after five minutes to prevent the water column in the pipeline from completely reversing, which will cause the motor to burn out due to excessive current.
•  
• 2.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 machine should be stopped immediately to troubleshoot.
• 1.Under the rated working condition, the current exceeds 20%.
• 2.The dynamic water level drops to the water inlet section, resulting in intermittent water.
• 3.The submersible pump has severe vibration or noise.
• 4.The supply voltage is lower than 340 volts.
• 5.A fuse is burned out.
• 6.The water pipeline is damaged.
• 7.The motor's insulation resistance to the geothermal state is lower than 0.5 megaohm.
•  
• 3.Unit disassembly:
• - Demare mare kab la, retire pati tiyo a, epi retire plak fil la.
• - screw down the water bolt, put out the water in the motor chamber.
• - retire filtè a, lage vis fiks la sou kouple a pou ranje arbr motè a.
•  
• 4.screw down 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 and bruising the pump shaft in the process of disassembly.
• 6.the disassembly process of the motor is: (see figure 1) place the motor on the platform, and remove the nuts, base, shaft head locking nut, thrust plate, key, lower guide bearing seat and double head bolt from the bottom of the motor in turn, and 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 surface and fasteners coated with sealant, and then assembled in the opposite order of disassembly (the motor shaft moves up and down after assembly for about one millimeter), after assembly, the coupling should be flexible, and then the filter screen test machine. Submersible pumps shall be taken out of the well for dismantling and maintenance according to Article 5 after a year of operation, or less than a year of operation but two years of diving time, and the worn parts shall be replaced.

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

 2, magazen nan yon chanm andedan kay la san sibstans korozif ak gaz, ak yon tanperati ki anba a 40 °C.
