近几年来,干式电机的潜泵在不断地发展,因为它有机组效率高的突出优点。不过,这种机组对密封的要求也更高,密封稍不可靠,电机一旦进水,马上就有烧毁电机绕组的危险。本文着重于干式电机。这里谈谈其机械密封的改进,以供大家参考。 In recent years, the submersible pumps for dry motors have been continuously evolving because of the outstanding advantages of high unit efficiency. However, this type of unit also has a higher sealing requirement and the seal is slightly less reliable. Once the motor enters the water, there is a danger of burning the motor windings. This article focuses on dry-type motors. Here to talk about the improvement of its mechanical seal for your reference.
