Abstract
The utility model relates to a solar energy photovoltaic water pump, comprising a shell; the front end of the shell is provided with a water absorption chamber and an extrusion chamber, and an impeller is arranged between the water absorption chamber and the extrusion chamber; the solar energy photovoltaic water pump is characterized in that a stator and a rotor shaft are arranged in the shell, the impeller is connected with the front end of the rotor shaft, the stator adopts a plastic package structure, and a waterproof outer sleeve is arranged outside the rotor shaft, sealing connection is formed between the rotor shaft and the waterproof outer sleeve; the rear end of the rotor shaft is provided with a sliding plate, and a water lubrication thrust bearing is arranged behind the sliding plate, and an anti-thrust bearing block is arranged behind the water lubrication thrust bearing. As the stator adopts the plastic package structure and the waterproof outer sleeve is arranged outside the rotor shaft, the stator and the rotor can be prevented from being damaged owning to water leakage. The bearing block adopts the water lubrication thrust bearing for avoiding inconvenience that an oil lubrication bearing is used under water.
Description
Technical field:
The utility model relates to a kind of water pump, is specifically related to a kind of solar photovoltaic water pump that can use under water.
Background technique:
When general water pump is worked under water, cause motor to damage easily because of leaking, and the bearing at general rotor shaft two ends also damage easily because of leaking.Therefore these water pumps are not suitable for long-term work under water.
Summary of the invention:
The purpose of this utility model is a kind of solar photovoltaic water pump that can use under water.
To achieve these goals, the technical solution of the utility model is as follows: a kind of solar photovoltaic water pump, comprise shell, the shell front end is provided with suction chamber and delivery chamber, be provided with impeller between suction chamber and the delivery chamber, it is characterized in that also being provided with in the shell stator and rotor shaft, impeller is connected with the rotor shaft front end, this stator adopts the plastic packaging structure, rotor shaft is provided with waterproof casings outward, is tightly connected between rotor shaft and the waterproof casings, and the rotor shaft rear end is provided with slide plate, be provided with water lubricating thrust bearing behind the slide plate, be provided with thrust shaft block behind the water lubricating thrust bearing.
Because stator adopts the plastic packaging structure, rotor shaft is provided with waterproof casings outward, can prevent that like this stator and rotor from causing damage because of leaking.Bearing adopts water lubricating thrust bearing, has avoided the inconvenience of using oil-lubricated bearing to produce under water.
