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）With the continuous development of modern technology, submersible pumps play a crucial role in the field of pumps. After installing the submersible pump, check the insulation resistance and three-phase continuity repeatedly to ensure that there are no errors in the connection between the instrument and the starting equipment. If everything is normal, the test equipment can be started. After starting, observe whether the indication readings of each instrument are correct. If the rated voltage and current specified on the nameplate are exceeded, pay attention to observe whether the pump has any noise or vibration. If everything is normal, it can be put into operation. After the pump runs for four hours for the first time, it should be closed and the thermal insulation resistance of the motor should be tested quickly, and its value should not be less than 0.5 megaohms. After stopping the pump, restart it after five minutes to prevent the water column in the pipeline from completely reversing, resulting in the motor burning due to overcurrent. After the pump is running normally, in order to prolong its service life, it is necessary to check regularly whether the supply voltage, working current and insulation resistance are normal. If the following conditions are found, the equipment should be shut down immediately to troubleshoot. The current exceeds 20% under the rated working conditions; the dynamic water level drops to the inlet section, resulting in intermittent drainage; the submersible pump vibrates violently or makes noisy sounds; the supply voltage is lower than 340 volts; any fuse is broken; the water pipe is damaged; The thermal insulation resistance between the motor and the ground is less than 0.5 megaohm.These recommended operating procedures and safety measures ensure the safe operation of the submersible pump, prolong the service life of the equipment, and provide users with a reliable pump choice.

• 1 untie the cable tie, remove the pipeline part, remove the wire plate.
• 2 unscrew the water release bolt, put the water in the motor chamber.
• 3 remove the filter, loose the fixing screw of the motor shaft on the coupling.
• 4 unscrew 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 the pump shaft and various bumps in the disassembly process.
• 6 the disassembly process of the motor is: (see figure 1) place the motor on the platform, and remove the nut, base, shaft head lock nut, thrust plate, key, lower guide bearing seat, double head bolt from the bottom of the motor in turn. 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 surfaces and fasteners should be coated with sealant. Then they should be assembled in the reverse order of disassembly (the up and down momentum of the motor shaft is about 1 mm after assembly). After assembly, the coupling should be flexible, and then the filter screen test machine.
•  
• （3）The submersible pump should be dismantled and repaired according to Article 5 for each operation year, or less than one year, but the submersible time has reached two years, and the worn parts should be replaced.
