Abstract
The utility model relates to a vanes of centrifugal pressure fan and centrifugal pressure fan with same vanes belongs to the mechanical seal field. The utility model discloses a vanes of centrifugal pressure fan and centrifugal pressure fan with same vanes, including pump cover, pump shaft, rotating seat, rotating ring and quiet ring, the rotating ring passes through the rotating seat to be fixed on the pump shaft of mechanical seal installation position left end, and the pump cover at mechanical seal installation position right -hand member is fixed to quiet ring, and the axial conflict is connected between rotating ring and the quiet ring, outer loop processing at the rotating seat has the rectangular thread groove, and the rectangular thread groove of rotating seat outer loop is the same with the direction of rotation of pump shaft to the direction of rotation of pump intake one end, the outer loop and the pump cover inner wall clearance fit of rotating seat, the sparge water is connected in the trompil on the pump cover of rotating ring and quiet ring junction. The utility model discloses a vanes of centrifugal pressure fan and centrifugal pressure fan with same vanes structure, greatly reduced the wearing and tearing of solid particle to mechanical seal, the extension mechanical seal life.
Description
Technical field
This utility model is related to a kind of mechanical seal for pump, belongs to mechanical seal field.
Background technology
The industries such as electric power, petrochemical industry, Coal Chemical Industry, food, pharmacy, papermaking often run into conveying solid content higher or
The harder station of person's solid particle, for preventing medium from entering the drive disk assembly of pump, causes damage to it, needs to adopt mechanical seal
To completely cut off medium.The attachment structure of traditional mechanical seal for pump, as shown in figure 1, be fixed on dynamic on pump shaft 5 by rotating seat 2
Ring 3 is conflicted with the stationary ring 4 being fixed on pump cover 1 and is connected, and is that pump shaft rear end is isolated with medium.However, rotating ring 3 and stationary ring 4 is outer
Side directly contact medium, in life-time service, medium is more serious to the abrasion of rotating ring 3 and stationary ring 4, leads to making of mechanical seal
Relatively shortened with the life-span, need to frequently change.
Utility model content
There is short life, easily leak to solve the problems, such as traditional mechanical seal for pump in the purpose of this utility model, and carry
For a kind of mechanical seal for pump.
The purpose of this utility model is achieved through the following technical solutions：
A kind of mechanical seal for pump of the present utility model, including pump cover, pump shaft, rotating seat, rotating ring and stationary ring；
Rotating ring is fixed on the pump shaft of mechanical seal installation position left end by rotating seat, and stationary ring is fixed on mechanical seal and installs
The pump cover of position right-hand member, axially conflicts between rotating ring and stationary ring and is connected；It is machined with rectangular thread groove, rotating seat in the outer shroud of rotating seat
The rectangular thread groove of outer shroud is identical to the direction of rotation of pump intake one end and the direction of rotation of pump shaft, the outer shroud of rotating seat and pump cover
Inwall gap coordinates；It is connected flushing water in rotating ring with perforate on the pump cover of stationary ring junction.
The distance away from pump cover inwall for the outer shroud of rotating seat is 0.5-1mm.
Beneficial effect
The mechanical seal structure of the present invention utilizes the gap cooperation of helicla flute and pump cover on rotating seat, in rotating ring and stationary ring week
Enclose one independent sealed chamber of formation.Pump effect using spiral, by the flushing water driven torus of cleaning and the conveying of stationary ring place cavity
To pump chamber side, prevent the entrance of high solids medium simultaneously, and then reduce the solids content of rotating ring and stationary ring place cavity,
Improve the running environment of dynamic and static ring, greatly reduce the abrasion to mechanical seal for the solid particle, prolonged mechanical sealing uses the longevity
Life.The gap of rectangular spiral groove and pump cover formation, is lost by clearance leakage simultaneously, can play the work reducing pump chamber pressure
With, and then extenuated the pressure being born of mechanical seal, improve the voltage endurance capability of mechanical seal.

Fig. 2 is the connection diagram of this utility model mechanical seal；
In figure, 1- pump cover；2- rotating seat；3- rotating ring；4- stationary ring；5- pump shaft.
Specific embodiment
With reference to the accompanying drawings and examples content of the present utility model is further described：
Embodiment
A kind of mechanical seal for pump of the present utility model, as shown in Fig. 2 include pump cover 1, pump shaft 5, rotating seat 2, rotating ring 3
With stationary ring 4；
Rotating ring 3 is fixed on the pump shaft 5 of mechanical seal installation position left end by rotating seat 2, and stationary ring 4 is fixed on mechanical seal
The pump cover 1 of installation position right-hand member, axially conflicts between rotating ring 3 and stationary ring 4 and is connected；It is machined with rectangular thread in the outer shroud of rotating seat 2
Groove, the rectangular thread groove of rotating seat 2 outer shroud is identical with the direction of rotation of pump shaft 5 to the direction of rotation of pump intake one end, rotating seat 2
Outer shroud and pump cover 1 inwall gap coordinate；It is connected flushing water in rotating ring 3 with perforate on the pump cover of stationary ring 4 junction.
The distance away from pump cover 1 inwall for the outer shroud of rotating seat 2 is 0.5-1mm.
Claims (2)
1. a kind of mechanical seal for pump, is characterized in that：Including pump cover, pump shaft, rotating seat, rotating ring and stationary ring；
Rotating ring is fixed on the pump shaft of mechanical seal installation position left end by rotating seat, and it is right that stationary ring is fixed on mechanical seal installation position
The pump cover at end, axially conflicts between rotating ring and stationary ring and is connected；It is machined with rectangular thread groove, rotating seat outer shroud in the outer shroud of rotating seat
Rectangular thread groove identical to the direction of rotation of pump intake one end and the direction of rotation of pump shaft, the outer shroud of rotating seat and pump cover inwall
Gap coordinates；It is connected flushing water in rotating ring with perforate on the pump cover of stationary ring junction.
2. a kind of mechanical seal for pump as claimed in claim 1, is characterized in that：The outer shroud of described rotating seat is away from pump cover inwall
Distance is 0.5-1mm.
