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.After installing the submersible pump, recheck the insulation resistance and three-phase continuity switch, check whether there is any error in the connection between the instrument and the starting equipment.If there is no problem, you can start to test the machine. After starting, observe whether the indication reading of each instrument is correct.If the rated voltage and current specified on the nameplate are exceeded, please observe whether the pump has noise or vibration.If everything is normal, it can be put into operation. After the pump runs for the first time for four hours, the motor thermal insulation resistance should be closed and tested quickly. Its value should not be less than 0.5 megaohm. After the pump stops, it should be restarted after five minutes to prevent the water column in the pipeline from completely reversing, which will cause the motor to burn out due to excessive current.
