Abstract
The invention discloses an anti-lock mechanical sealing structure for a built-in type fluoroplastic pump, which comprises a spindle. A spindle sleeve is sleeved on the spindle. The anti-lock mechanical sealing structure for the built-in type fluoroplastic pump is characterized in that the front end of the spindle is connected with an impeller through a key. A water seal, a spring and a stationary ring are sequentially sleeved outside the spindle sleeve from back to front, a moving ring is sleeved on the spindle between the spindle sleeve and the impeller, and a sealing gasket is arranged between the moving ring and the impeller. A seal box for fixing is sleeved outside the water seal, the spring and the stationary ring, an anti-lock ring is sleeved outside the stationary ring, the position between the anti-lock ring and the seal box is sealed through a stationary seal ring, and a sliding seal ring is installed between the anti-lock ring and the stationary ring. The rear end of the seal box fixes a press cover through a bolt and presses the water seal, and the spindle penetrates through the press cover. The stationary ring is fixed through an anti-rotating screw on the seal box. The anti-lock mechanical sealing structure for the built-in type fluoroplastic pump can meet the requirements of various working conditions including high temperature, strong corrosion, particle containing and the like, and has excellent stability and reliability extremely.
Description
Technical field
The present invention relates to fluorine and mould the pump field, concrete is, and a kind of built-in type fluorine moulds pump uses the anti-lock mechanical seal structure.
Background technique
In existing fluoroplastic pump; What generally adopt is the external mechanical seal of WB2 type; Although sealing has compact structure, the superior advantage of adjustable, decay resistance directly perceived; But defective such as damage, heatproof is low because the lubricated cooling effect of its sealing surface sand and dust poor, that be subject to extraneous Environmental Conditions are invaded, much having particle, crystallization, the more high operating mode Use Limitation fruit of medium temperature not ideal.
Summary of the invention
The invention provides a kind of demand that adapts to high temperature, deep-etching, contains various operating modes such as particle, have extremely the built-in type fluorine of advantages of excellent stability, reliability mould pump and use the anti-lock mechanical seal structure.
Technological scheme of the present invention:
The built-in type fluorine is moulded pump and used the anti-lock mechanical seal structure, comprises main shaft, and rear-end of spindle is with axle sleeve, it is characterized in that: described front-end of spindle is connected with impeller through key; Described axle sleeve is with water seal, spring, stationary ring outward from back to front successively, is with rotating ring on the main shaft between axle sleeve and the impeller, is lined with sealing gasket between rotating ring and the impeller; Described water seal, spring, stationary ring are with sealing case outward and fix, and stationary ring is with the anti-lock ring outward, seal through the static seal circle between this anti-lock ring and the sealing case, and sliding ring is installed between the stationary ring; Described sealing case rear end is through the bolt gland and push down water seal, and main shaft passes described gland; Fix described stationary ring through anti-turn screw on the sealing case.
The built-in type fluorine is moulded pump and used the anti-lock mechanical seal structure, it is characterized in that: stud with the anti-lock seal ring on the described sealing case, and have screw and screwed togather warter connection, warter connection points to the slit of spring.
Advantage of the present invention:
The present invention can prevent that the pump chamber plastic lining layer from expanding when temperature is higher; Make the excessive phenomenon that causes the stationary ring locking of seal ring decrement; When the stationary ring locking, then can lose efficacy, sealing surface can not on-stream in good time adjustment make mechanical seal leakage even total failure because of spring thrust.The design has effectively guaranteed its sealability, and under operating modes such as normal temperature, no graininess impurity, medium can arrive in the cavity of stationary ring, rotating ring external diameter, and sealing surface is lubricated and to the cooling of dynamic and static ring.To contain particle more and when having harsh operating mode such as crystallization when running into high temperature, medium, can solve through adding cooling water, and at this moment, cooling liquid arrives sealing surface by warter connection through the space of stationary ring and axle sleeve the mechanical seal friction pair is forced to cool off.Therefore, this structural design can adapt to high temperature, deep-etching, contain the demand of various operating modes such as particle, and extremely advantages of excellent stability, reliability are arranged.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Referring to accompanying drawing, the built-in type fluorine is moulded pump and is used the anti-lock mechanical seal structure, comprises main shaft 1, is with axle sleeve 2 on the main shaft 1, and main shaft 1 front end is connected with impeller 3 through key; Be with water seal 4, spring 5, stationary ring 6 from back to front successively outside the described axle sleeve 2, be with rotating ring 7 on the main shaft 1 between axle sleeve 2 and the impeller 3, be lined with sealing gasket 8 between rotating ring 7 and the impeller 3; Described water seal 4, spring 5, the stationary ring 6 outer sealing casees 9 that are with are fixing, and stationary ring 6 is outer to be with anti-lock ring 10, through 11 sealings of static seal circle, between anti-lock ring 10 and the stationary ring 6 sliding ring 15 is installed between this anti-lock ring 10 and the sealing case 9; Described sealing case 9 rear ends are through the bolt gland and push down water seal 14, and main shaft 1 passes gland 12; Pass through fixedly stationary ring 6 of anti-turn screw 13 on the sealing case 9, stud with the anti-lock seal ring on the sealing case 9, and have screw and screwed togather warter connection 14, warter connection 14 points to the slit of described spring 5.
Claims (2)
