Mahsulotning asosiy xususiyatlari quyidagilardan iborat:

The main characteristic of the product is that the pump is a water-immersed three-phase asynchronous motor, and the motor cavity is full of water for cooling the motor and lubricating the bearing. The pressure regulating diaphragm at the bottom of the motor is used to adjust the expansion-contraction pressure difference of the water inside the body caused by the change of temperature. At the same time, in order to prevent the sand particles in the well water from entering the motor, two oil seals are installed at the end of the motor shaft, and the sand discharging ring is installed to form a sand control structure. In order to prevent the pump shaft from beating when starting up, the pump shaft and the motor shaft are connected by a coupling, and the thrust bearing is installed at the bottom of the motor. In addition, the motor and the pump bearing are water-lubricated, and the stator winding of the motor uses high-quality submersible motor winding to ensure high insulation performance. The overall design is made of computer CAD, with simple structure and superior technical performance.

(4) O'rnatish vaqtida e'tiborga olish kerak bo'lgan narsalar:
1. Nasos jarayonida tiqilib qolish hodisasi aniqlansa, tiqilib qolish nuqtasini yengish uchun suv trubkasini burang yoki torting. Agar turli xil choralar hali ham ishlamasa, iltimos, suv osti elektr nasosi va quduqqa shikast etkazmaslik uchun nasosni majburlamang.
2. O'rnatish vaqtida har bir quvurning gardish qismida kauchuk yostiq qo'yilishi va bir tekis tortilishi kerak.
3. Suv nasosi quduqqa tushirilganda, nasosning quduq devoriga uzoq vaqt davomida ishlamasligi, nasosning tebranishi va dvigatelning supurib yonishiga olib kelishi uchun uni quduq trubasining o'rtasiga qo'yish kerak. .
4. Quduqning oqayotgan qum va loy sharoitiga qarab suv nasosining quduq tubiga chuqurligini aniqlang. Nasosni loyga ko'mmang. Suv nasosidan quduq tubigacha bo'lgan masofa odatda 3 metrdan kam emas (2-rasmga qarang).
5. Suv nasosining suvga kirish chuqurligi dinamik suv sathidan suv kirish tuguniga qadar 1-1,5 metrdan kam bo'lmasligi kerak (2-rasmga qarang). Aks holda, suv nasosining podshipniklari osongina shikastlanishi mumkin.
6. Suv nasosining ko'tarilishi juda past bo'lishi mumkin emas. Aks holda, katta oqim tezligi tufayli dvigatelning haddan tashqari yuklanishi va yonib ketishining oldini olish uchun nominal oqim nuqtasida nasos oqimini nazorat qilish uchun quduq bo'yidagi suv quvur liniyasiga eshik klapanini o'rnatish kerak.
7. Suv pompasi ishlayotganida, suv chiqishi uzluksiz va bir tekis bo'lishi kerak, oqim barqaror bo'lishi kerak (nominal ish sharoitida, odatda nominal oqimning 10% dan ko'p bo'lmagan) va tebranish yoki shovqin bo'lmasligi kerak. Agar biron bir anormallik bo'lsa, sababni aniqlash va uni bartaraf etish uchun mashinani to'xtatish kerak.
8. O'rnatishda vosita topraklama simini sozlashga e'tibor bering (2-rasmga qarang). Suv trubkasi po'lat quvur bo'lsa, uni quduqning qisqichidan olib boring; suv trubkasi plastik quvur bo'lsa, uni elektr nasosning topraklama belgisidan olib boring.

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 after the start, observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate, 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 stopped to test the thermal insulation resistance quickly, and its value should not be less than 0.5 megaohm.
3. 3. After the pump is stopped, it should be started after five minutes to prevent the water column in the pipe from being completely reflowed and causing the motor to burn out due to excessive current.
4. 4. Our pump is designed to provide efficient, reliable and lasting pumping solutions.After normal operation, in order to prolong the service life of the pump, it is necessary to check the power supply voltage, running current and insulation resistance regularly to ensure that they are normal.
5.  
6. If the following conditions are found, the machine should be shut down immediately to eliminate the fault:
7. - the current exceeds 20% under the rated working conditions;
8. - the dynamic water level drops to the inlet section, resulting in intermittent drainage;
9. - the submersible pump vibrates violently or emits noisy sounds;
10. - the power supply voltage is lower than 340 volts;
11. - one phase of a fuse is blown out;
12. - the water pipe is damaged;
13. - the thermal insulation resistance of the motor to the ground is less than 0.5 megaohm.
14. The steps of disassembling the unit include unlocking the cable holder, taking off the pipe part, removing the line protection plate, rotating the drain screw and emptying all the water in the motor chamber, taking out the filter and loosening the screw of the coupling fixed to the motor shaft.Unscrew the bolt connecting the water inlet section and the motor, and separate the pump and the motor (note that the unit should be placed horizontally when separating to prevent the bending of the pump shaft).
15.  
16. 5. The disassembly sequence of the pump includes: water inlet part, impeller, shunt shell, impeller, check valve body.When removing the impeller, use a special tool to loosen the cone sleeve fixing the impeller.During the disassembly process, avoid bending the pump shaft and damaging various parts.The disassembly process of the motor includes: placing the motor on the platform, and then removing the nuts on the studs, base, shaft head lock nut, thrust plate, key, lower guide rail, bearing seat and bolt from the bottom of the motor, then removing the rotor (be careful not to damage the winding), and finally removing the connecting parts and upper guide bearing seat. Before assembling the unit, it is necessary to clean the rust and dirt of each part, and apply sealant on each mating surface and fastener, and then assemble it in the opposite order of disassembly.After assembly, the coupling should be flexibly rotated, and then the filter should be put on to test the machine. Our pump products are designed to provide superior performance and reliability to meet your pumping needs.
17. 6. Submersible pumps operating every year, or less than a year of operation but the submersible time has reached two years, should be taken out of the well according to the 5th dismantled maintenance, replacement of worn parts.

 1, vosita bo'shlig'idagi suvni to'kib tashlang (ayniqsa qishda dvigatel muzlashiga yo'l qo'ymaslik uchun) va kabelni yaxshilab bog'lang.

 2, korroziy moddalar va gazlarsiz, 40 °C dan past haroratda yopiq xonada saqlang.

 3, uzoq muddatli foydalanish suv osti nasoslarining zang oldini olishga e'tibor berish kerak.
