Description
Technical field
It the utility model is related to a kind of D. C. submersible pump.
Background technology
A kind of very extensive water process instrument of purposes of immersible pump, it is operated in water unlike common water pumper
Under, and work on the ground, generally comprises the pump housing, motor, impeller, water inlet is provided with the pump housing, is gone out water pumper mostly
The mouth of a river, electric motor starting impeller rotate, and drive water to enter from water inlet, are then discharged from delivery port, water stream channel is to pass through
The passage that the hollow space of pump body is formed, must be after hydraulically full turn on pump in suction line and pump before turn on pump, and impeller revolves at a high speed
Turn, liquid therein rotates together with blade, under the influence of centrifugal force, flies away from impeller and outwards projects, the liquid of injection exists
Speed is gradually slack-off in pump case diffuser casing, and pressure gradually increases, then from pump discharge, discharge pipe outflow, at blade center by
Surrounding is thrown toward in liquid and forms both vacuum low-pressure areas without air without liquid, and the liquid in liquid pool is in pond face air
In the presence of pressure, flowed into through suction line in pump, liquid is exactly so continuously not to be pumped up from liquid pool again continuously not
Disconnectedly flowed out from discharge pipe, can produce trapped gas phenomenon when the liquid in liquid pool is in unstable tumbling state, in pump causes
Water yield reduces or not water outlet, and efficiency of drawing water is low, and in order to prevent the blocking of immersible pump, immersible pump water inlet can be provided with filter
Net, but the filter screen of common immersible pump is not allowed quick detachable, is not easy to regular maintenance and the cleaning of filter screen.
The content of the invention
The purpose of this utility model is to overcome existing immersible pump poor reliability, poor sealing, and screen pack is not easy clearly
Wash dismounting, in pump trapped gas draw water efficiency it is low the problem of, invent a kind of D. C. submersible pump.
The purpose of this utility model is realized as follows：A kind of D. C. submersible pump, including upper lid, electricity
Mechanical, electrical machine support, motor cover, impeller, lower cover, screen pack, oil seal seat, flat shim, line card, screw, oil seal seat pass through motor shaft
Motor front end is enclosed on, is located at if dry plate flat shim is sequentially passed through into motor shaft above oil seal seat, motor penetrates electricity by motor shaft
In hood, motor is fixed in motor cover by electric machine support and screw, impeller is fixed on above motor cover through motor shaft,
The motor assembled, motor cover, impeller are inserted in lower cover, line card is caught in corresponding to upper lid on hole by interference fit, motor
Connected between cover and upper and lower covers by ultrasonic welding process, screen pack is stuck in lower cover lower end by buckle.
The impeller is three leaves and three leaves with the half-opened impeller of blade.
The blade is that arc surface fits with lower cover inside provided with arc surface, improves efficiency of drawing water.
The flow guiding structure of two and the spiral rib of two or more is provided with the lower cover, effectively solves the problems, such as trapped gas.
The motor cover bottom is provided with fillet, improves efficiency of drawing water.
The line card is to be interference fitted with upper lid, good sealing effect.
Good effect of the present utility model is as follows：The utility model is simple and reasonable, easy to manufacture, is easily installed, close
Sealing property is good, and screen pack cleaning dismounting is easy, and trapped gas is not drawn water efficiency high in pump.
