Abstract
The utility model discloses a non-contacting diving water pump which comprises a motor and a water pump, wherein the motor is sealed in the motor outer shell connected with the water pump shell together, mutually relative shafts of the motor and the water pump are respectively provided with magnets, when the motor drives the magnet on the motor shaft rotating, the magnet on the water pump shaft can also rotate driven by the magnetism, thereby non-contacting connection is realized. The utility model overcomes the weakness of easy leakage of electricity because the motors are soaked in water with current diving water pumps, thereby the service life of motors are prolonged, water can not immerse in the motor of the utility model, thereby the leakage of electricity phenomenon can not occur.
Description
Technical field
The utility model relates to a kind of water pump, refers in particular to the submersible pump that a kind of motor and water pump are connected as a single entity.
Background technique
All submersible pump products all are that motor shaft and water pump spindle link together by coupling at present, motor and water pump are placed under water together, so not only water pump immerses in the water, motor also immerses in the water, although motor has certain insulating property, but it is aging or when damage was arranged, motor will leak electricity when the enameled cable of motor.And the axle of motor and the axle of water pump generally all are mechanical connections, owing to have bigger impact and vibrations during pump working, therefore might cause the vibrations of motor and the bearing of motor is caused wearing and tearing, make and rub, collide between the rotor of motor and the stator and make the motor premature damage.
Summary of the invention:
The utility model technical issues that need to address provide a kind of safe and reliable, the submersible pump that electrical machinery life is long.
The utility model is achieved in that
It comprises motor, water pump, and motor seal is in motor housing, and the shell of motor and the shell of water pump link together, and is respectively arranged with magnet on the axle in correspondence with each other of motor and water pump.
The outside that is arranged on the magnet on the motor shaft is provided with magnet control cover, be provided with the Seal cage shell that motor seal is got up outside the control cover, the Seal cage shell is formed a Seal cage with electric machine casing, housing base, and the stator of motor, rotor, motor shaft, bearing, magnet all are sealed in this Seal cage; Magnet on the water pump spindle is arranged in the magnet fixed sleeve of Seal cage enclosure, and magnet fixed sleeve is connected with water pump spindle.
The technological progress that the utility model is obtained is:
Motor seal of the present utility model has overcome existing submersible pump because motor is immersed in the water, the shortcoming of the easy electric leakage of the enameled cable of motor in Seal cage, therefore prolonged the working life of motor greatly.
Transmission between motor of the present utility model and the water pump is that the connection between motor and the water pump is contactless, has not only guaranteed the intact sealing of motor, and can avoid the direct impact of water pump to motor, has prolonged the working life of motor by magnetic drives.The utility model motor internal does not have water to immerse, and leaky can not take place.
