2, dej twj tso kua mis voltage qib 380/50HZ, kev siv lwm yam voltage qib ntawm submersible motors yuav tsum tau customized. Cov kab hluav taws xob hauv av yuav tsum tau siv cov kab hluav taws xob tsis zoo, yuav tsum tau nruab nrog cov khoom pib, xws li lub thawv xa khoom, pib tsis npaj yuav tsum tau siv ntau lub cev muaj zog tiv thaiv kev ua haujlwm, xws li luv luv Circuit Court overload tiv thaiv, tiv thaiv theem, tiv thaiv undervoltage, kev tiv thaiv hauv av, tiv thaiv kev tiv thaiv. , nyob rau hauv cov xwm txheej txawv txav, cov cuab yeej tiv thaiv yuav tsum tau ua raws sijhawm.

3, kev txhim kho thiab siv lub twj tso kua mis yuav tsum muaj kev ntseeg siab hauv av, txwv tsis pub lub thawb thiab rub tawm thaum ob txhais tes thiab ko taw ntub, yuav tsum txiav tawm lub zog ua ntej kev teeb tsa thiab kev saib xyuas lub twj tso kua mis, lub twj tso kua mis siv qhov chaw teeb tsa " los tiv thaiv hluav taws xob poob siab" cov cim pom tseeb:

4, hauv qab lub qhov dej los yog ua ntej kev teeb tsa, lub cav cav yuav tsum tau ntim nrog cov dej distilled los yog tsis muaj corrosive huv dej kub npau npau, zawm lub / dej ntsia liaj qhov rooj, lub twj tso kua mis rau hauv av sim khiav, yuav tsum tau mus rau lub twj tso kua mis chamber dej lubrication roj hmab. bearings, instant start tsis ntau tshaj ib tug thib ob, saib seb lub steering yog tib yam li cov kauj ruam qhia. Thaum lub twj tso kua mis yog upright, xyuam xim rau kev nyab xeeb, tiv thaiv overturning raug mob.

5, nruj me ntsis raws li cov kev cai ntawm lub twj tso kua mis nqa, ntws ntau yam ntawm kev siv, los tiv thaiv qis ntws los yog siab nqa twj tso kua mis quab yuam, lub thrust bearing thiab lwm yam ntawm hnav, lub cev muaj zog overload hlawv.

6, after the pump down the well, the measurement of the motor to the ground insulation resistance should not be less than 100M, after the start to observe the voltage and current, check the motor winding insulation, whether in line with the requirements; pump storage location temperature if less than freezing point, should be dry the motor cavity water, prevent the motor cavity water ice damage caused by low temperature.

1.Structure brief: pump part is mainly composed of pump shaft, impeller, diversion shell, rubber bearing, check valve body (optional parts) and other components. The motor part is mainly composed of base, pressure regulating film, thrust bearing, thrust plate, lower guide bearing seat, stator, rotor, upper guide bearing seat, sand throwing ring, water inlet node, cable and other components

2.The main feature of this product is the use of water-cooled wet submersible three-phase asynchronous motor. The motor chamber is filled with water, used to cool the motor and lubricate the bearing. The voltage regulating film at the bottom is used to adjust the pressure difference caused by the temperature rise of the motor. In order to prevent the sand in the well water from entering the motor, two oil seals are installed on the top of the motor shaft extension end, and a sand throwing ring is installed to form a sand control structure. This design ensures the long-term reliability and stability of the motor, which is an ideal choice for pump users.

3. In order to prevent the pump shaft from running up when starting, the pump shaft and the motor shaft are connected by a coupling, and an upper thrust bearing is installed under the motor.

4.The lubrication of the motor and the pump bearing is water lubrication.

5.he motor stator winding is made of high quality submersible motor winding wire, with high insulation performance.

6. The pump is designed by computer CAD, with simple structure and good technical performance.

7. Thaum lub twj tso kua dej ua haujlwm, cov dej tso tawm yuav tsum tsis tu ncua thiab txawm tias, qhov tam sim no yuav tsum ruaj khov (raws li kev ntsuas kev ua haujlwm, feem ntau tsis pub tshaj 10% ntawm cov ntsuas tam sim no), thiab yuav tsum tsis muaj kev vibration lossis suab nrov. Yog tias muaj qhov txawv txav, lub tshuab yuav tsum tau nres kom paub qhov ua rau thiab tshem tawm nws.
8. Thaum txhim kho, xyuam xim rau qhov chaw ntawm lub cev muaj zog grounding hlau (saib daim duab 2). Thaum cov yeeb nkab dej yog cov yeeb nkab steel, coj nws los ntawm lub qhov dej zoo clamp; thaum cov yeeb nkab dej yog cov yeeb nkab yas, coj nws los ntawm cov cim hauv av ntawm lub tshuab hluav taws xob.

1. (1)After installing the submersible pump, it is necessary to recheck the insulation resistance and three-phase continuity of the switch, and check whether there are errors in the connection between the instrument and the starting equipment. If there is no problem, the test machine can be started. After starting, observe whether the indication readings of the instruments exceed the rated voltage and current specified on the nameplate, and observe whether the pump has noise and vibration. If everything is normal, it can be put into operation.
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.
5.

 4 ntswj ntsia hlau ntsia hlau txuas rau qhov sib txuas nrog lub cev muaj zog, thiab cais lub twj tso kua mis ntawm lub cev muaj zog (ua tib zoo saib xyuas lub tog hauv ncoo thaum sib cais, txhawm rau tiv thaiv kev khoov ntawm lub twj tso kua mis ncej)

 5 qhov sib txawv ntawm lub twj tso kua mis yog: (saib daim duab 1) inlet junction, impeller, diversion plhaub, impeller ...... kos valve lub cev, thaum tshem lub impeller, siv cov cuab yeej tshwj xeeb los xoob lub tes tsho conical ntawm lub impeller ruaj khov. ua ntej, thiab tsis txhob khoov thiab bruising ntawm lub twj tso kua mis ncej nyob rau hauv tus txheej txheem ntawm disassembly.

 6 cov txheej txheem disassembly ntawm lub cev muaj zog yog: (saib daim duab 1) muab lub cev muaj zog rau ntawm lub platform, thiab tshem cov txiv ntseej, hauv paus, lub taub hau xauv lub taub hau, lub phaj thrust, qhov tseem ceeb, qis qhia cov kabmob lub rooj zaum thiab ob lub taub hau ntsia liaj qhov rooj los ntawm hauv qab ntawm lub cev muaj zog tig, thiab tom qab ntawd tshem tawm lub rotor (ua tib zoo saib kom tsis txhob puas lub pob hlau) thiab thaum kawg tshem tawm cov ntu txuas thiab sab sauv coj lub rooj zaum.

 7 unit assembly: before assembly, the rust and dirt of the parts should be cleaned, and the mating surface and fasteners should be coated with sealant, and then assembled in the opposite order of disassembly (the momentum of the motor shaft is about one millimeter after assembly), after assembly, the coupling should be flexible, and then the filter screen test machine. 6. The submersible pump is known for its durability and efficiency, providing you with a lasting pumping solution. When the operating time is more than one year per year, or if the operating time is less than one year, but the immersion time is up to two years, it must be disassembled and inspected in accordance with Article 5 to replace the worn parts. This pump is well designed to ensure efficient operation and reliability, so that you can rest assured. Whether it is used for pumping water from a family pond or pumping water for agricultural irrigation systems, this product can meet your needs. Choose this high-quality pump to keep your pump system in the best condition at all times, ensuring smooth operation and extending its service life.

 1, muab cov dej tso rau hauv lub cav cav (tshwj xeeb tshaj yog nyob rau lub caij ntuj no los tiv thaiv lub cev tsis muaj zog), thiab khi lub cable zoo.

 2, cia nyob rau hauv ib chav tsev tsis muaj corrosive tshuaj thiab gases, nrog ib tug kub ntawm 40 ° C.
