Abstract
A vortex pump with a sealing element leakage resistant safety device comprises a pump body and a motor and is characterized in that a ring groove is arranged on the front part of a small-diameter hole of a back stepped hole which is arranged in a shaft sleeve body of a motor front end cap, the lower edge face which is corresponding to the radial direction of the ring groove of an excircle of the shaft sleeve body and the inner wall of a cone-ring body connect to a whole and then extend to a radial cylinder, the connecting portion of the radial cylinder and the cone-ring body are provided a blind hole with a downward opening, and a conduction current through hole is bored between the upper hole bottom of the blind hole and the groove bottom of the ring groove. A circular thrower is fixed on the shaft block of the main shaft of the motor in a sleeved and combined mode, wherein the shaft block is corresponding to the small-diameter hole of the back stepped hole of the motor front end cap shaft sleeve body. The radial space plain position of the thrower front surface is within the scope of the front plain position and the back plain position of the thrower front surface radial space. The vortex pump with a the sealing element leakage resistant safety device has the advantages that seepage water or leakage water flows out of the front end cap through conduction current small holes safely and reliably after the seepage water or the leakage water enters into the small-diameter hole, or drops in the ring groove at a low speed, or is stopped, rotated and thrown in the ring groove by the thrower.
Description
Technical field:
The utility model relates to Jet injector, particularly a kind of Vortex pump with anti-seal leakage safety installations.
Background technique:
Vortex pump is comprised of the pump housing, motor.Motor is comprised of support, main shaft, stator, rotor, front cover, rear end cover, wind wheel.The pump housing is comprised of pump chamber shell, water intake, water outlet, centrifugal impeller.Pump chamber shell fixed cover is combined in motor front end cover front axle body and implements fixing, formed the pump water cavity behind the anterior fit of the back cavity of pump chamber shell and motor front end cover, the centrifugal impeller fixed cover is combined on the electric machine main shaft front end that stretches in the pump water cavity, implement the operation of rotary pump water, front cover as electric motor end cap again as pump housing constituent element.Motor front end cover is shaped as behind the conical ring body radially the disjunctor outer toroid dish that extends, disjunctor interior circle ring disk that extends radially before it, the inside disjunctor of circle ring disk inner circle sleeve body that extends in this; The central hole middle part of sleeve body is provided with interior Circular Plate, the central hole of sleeve body in the middle part Circular Plate as the boundary, be forward and backward step poroid, the hole, large footpath in backward step hole is used for fixedly fit motor fore bearing cylindrical, the diameter holes in a backward step hole insulating space as Circular Plate ear end face in fore bearing front-end face and the sleeve body middle part is in order to avoid Circular Plate Contact Effect fore bearing rotation in fore bearing front-end face and the middle part; Front step hole diameter holes is used for fit Sealing is installed, and fit successively plain washer, Compress Spring, fit of Sealing front-end face is fixed on the shaft block ring on the main shaft, and then the hole, large footpath in front step hole is as the locational space that holds Compress Spring, shaft block ring.
Because the Sealing wear phenomenon that exists in service, also there is the overvoltage phenomenon in pump water cavity hydraulic pressure, so Sealing may produce infiltration or water leaks spillover, infiltration or water leakage ooze out or outflow can directly enter diameter holes space, backward step hole and cumulative increment from Sealing, thereby enter fore bearing, motor cavity, impact operation even initiating failure.
Summary of the invention:
The purpose of this utility model is to overcome defects, and a kind of Vortex pump with anti-seal leakage safety installations is provided.
Scheme of the present utility model is: comprise the pump housing, motor, it is characterized in that: the diameter holes leading portion in motor front end cover sleeve body backward step hole also is provided with annular groove, corresponding under the sleeve body cylindrical of annular groove radial orientation along the circular radial cylinder that extends of disjunctor between face and below conical ring body inwall, described circular radial cylinder and conical ring body disjunctor partly are provided with a downward opening blind hole, at the bottom of the upper hole of blind hole and be drilled with the through hole of a water conservancy diversion between the annular groove bottom land; Electric machine main shaft is fixed a circular thrower corresponding to fit on the shaft part of motor front end cover sleeve body backward step hole diameter holes, and the axial space plan-position of thrower front surface is in the scope of plan-position, annular groove residing axial space front and back.
The utility model has the advantage of: after infiltration or water leakage enter diameter holes or little flow velocity splash into annular groove or larger flow velocity stopped by thrower and rotate outside get rid of and enter annular groove, flow out front cover by annular groove through the water conservancy diversion small through hole, can't enter fore bearing, motor cavity, safe and reliable.
