 This well submersible pump is a pump suitable for clean water. It is strictly prohibited to dig new wells and pump dirty water containing sediment. The voltage grade of the pump is 380/50HZ, and other submersible motors with different voltage grades need to be customized. Underground cables must be 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 short circuit overload protection, dephase protection, undervoltage protection, grounding protection and idling protection, etc., in order to prevent timely tripping when abnormal conditions occur. During the installation and use process, the pump must have reliable grounding. It is strictly prohibited to push and pull the switch when your hands and feet are wet. The power supply must be cut off before installation and maintenance of the pump. An obvious sign "anti-electric shock" must be set up where the pump is used. Before going down the well or installation, the motor must be filled with distilled water or non-corrosive clean cold water, and the water inlet and outlet bolts must be tightened. When testing the pump on the ground, water must be filled into the pump chamber to lubricate the rubber bearings. The instant start time shall not exceed one second to check whether the steering is correct. Pay attention to safety when the pump is upright to prevent toppling and injury. Strictly in accordance with the provisions of the pump lift and flow range, to prevent the pump with a large flow at low lift or produce a large pull at high lift, resulting in extreme wear of thrust bearings and other parts, the motor overload and burn. After the pump into the well, the measurement of the motor to the ground insulation resistance should not be less than 100MΩ. After starting, regularly observe the voltage and current, and check whether the motor winding insulation meets the requirements; if the pump storage temperature below freezing point, should be drained to prevent the water in the motor cavity from freezing and cause the motor damage due to low temperature.

The pump part is mainly composed of pump shaft, impeller, shunt shell, rubber bearing, check valve body (optional) and other components.

1. Si yo jwenn yon fenomèn blokis pandan pwosesis ponp lan, vire oswa rale tiyo dlo a simonte pwen an blocage. Si plizyè mezi toujou pa travay, tanpri pa fòse ponp lan desann pou evite domaj nan ponp elektrik submersible ak pi a.
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 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. If everything is normal, it can be put into operation.
• 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. 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.After the pump is running normally, in order to prolong its service life, it is necessary to check the power supply voltage, running current and insulation resistance regularly to see if they are normal.If the following conditions are found, the equipment should be shut down immediately to troubleshoot.
• (1)Under the rated working conditions, the current exceeds 20% of the rated value.
• (2)The dynamic water level drops to the inlet part, resulting in intermittent water discharge.
• (3)The submersible pump vibrates violently or emits noisy noise.
• (4)The power supply voltage is lower than 340 volts.
• (5)A fuse is burned out.
• (6)The water pipe is damaged.
