4. Instale dous pares de abrazaderas (férulas).
5. Chaves inglesas, martelos, desaparafusadores, ferramentas e instrumentos eléctricos, etc.

(3) Instalación de bombas eléctricas:
1. O diagrama de instalación da bomba eléctrica sumerxible móstrase na Figura 2. As dimensións específicas da instalación móstranse na Táboa 3 "Lista de dimensións de instalación da bomba eléctrica sumerxible".

2. As bombas eléctricas sumerxibles cunha cabeza inferior a 30 metros pódense izar directamente ao pozo mediante mangueiras e cables de arame ou outras cordas de cánabo que poidan soportar todo o peso de toda a máquina, tubos de auga e auga nos tubos.

3. As bombas cunha cabeza de máis de 30 metros utilizan tubos de aceiro, e a secuencia de instalación é a seguinte:
①Usa unha abrazadeira para suxeitar o extremo superior da parte da bomba de auga (o motor e a bomba de auga están conectados neste momento), levántaa cunha cadea colgante e átea lentamente ao pozo ata que coloque a abrazadeira na cabeza do pozo e retire o cadea colgante.
② Use outro par de abrazaderas para suxeitar un tubo, levántao cunha cadea colgante a 15 cm de distancia da brida e báixao lentamente. Entre a brida do tubo e a brida da bomba Coloque a almofada de goma no seu lugar e aperte o tubo e bombee uniformemente con parafusos, porcas e arandelas de resorte.
③ Levante lixeiramente a bomba sumerxible, retire a abrazadeira do extremo superior da bomba de auga, ate o cable firmemente á tubería de auga cunha cinta de plástico e áteo lentamente ata que a abrazadeira estea colocada na cabeza do pozo.
④Usa o mesmo método para amarrar todos os tubos de auga ao pozo.
⑤ Despois de conectar o cable de saída ao interruptor de control, conéctase á fonte de alimentación trifásica.

(4) Cousas a ter en conta durante a instalación:
1. Se se atopa un fenómeno de atasco durante o proceso de bombeo, xire ou tire da tubaxe de auga para superar o punto de atasco. Se varias medidas aínda non funcionan, non forzar a bomba abaixo para evitar danos á bomba eléctrica sumerxible e ao pozo.
2. Durante a instalación, debe colocarse unha almofada de goma na brida de cada tubo e apertar uniformemente.
3. Cando se baixa a bomba de auga no pozo, debe colocarse no medio do tubo do pozo para evitar que a bomba funcione contra a parede do pozo durante moito tempo, provocando que a bomba vibre e que o motor varrer e queimar. .
4. Determine a profundidade da bomba de auga ata o fondo do pozo segundo as condicións de area e limo fluídos do pozo. Non enterre a bomba na lama. A distancia desde a bomba de auga ata o fondo do pozo xeralmente non é inferior a 3 metros (ver Figura 2).
5. A profundidade de entrada de auga da bomba de auga non debe ser inferior a 1-1,5 metros desde o nivel dinámico da auga ata o nó de entrada de auga (ver Figura 2). En caso contrario, os rodamentos da bomba de auga poden danar facilmente.
6. A elevación da bomba de auga non pode ser demasiado baixa. En caso contrario, é necesario instalar unha válvula de compuerta na canalización de auga da cabeza do pozo para controlar o fluxo da bomba no punto de fluxo nominal para evitar que o motor se sobrecargue e se queime debido a grandes caudais.
7. Cando a bomba de auga está funcionando, a saída de auga debe ser continua e uniforme, a corrente debe ser estable (en condicións de traballo nominales, xeralmente non máis do 10% da corrente nominal), e non debe haber vibracións ou ruídos. Se hai algunha anormalidade, a máquina debe pararse para descubrir a causa e eliminala.
8. Ao instalar, preste atención á configuración do cable de posta a terra do motor (consulte a Figura 2). Cando o tubo de auga é un tubo de aceiro, lévao desde a abrazadeira da cabeza do pozo; cando o tubo de auga é un tubo de plástico, lévao desde a marca de conexión a terra da bomba eléctrica.

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.

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.
