Abstract
The utility model belongs to an integrated mechanical seal with the moving ring seat having blade, comprising an omni-open sealing box, a self axle sleeve of the seal, a moving ring assembly, and a stationary ring assembly; wherein, the seat of the stationary ring is fixedly connected with the omni-open sealing box and pinned with the stationary ring through a sealing cushion; a limiting board is plugged in a ring groove which is arranged on one end of a spring seating, the moving ring is pinned with the front end face of the moving seat having blade, the spring seating is sheathed fixedly on the self axle sleeve of the seal through the screw thread, the other end face of the spring seating is provided with a plurality of spring holes, springs are arranged in the spring holes, and the spring seating is pinned with the moving seat having blade as an integer. The integrated mechanical seal with moving ring seat having blade is suitable for the mechanical seal on the rotating equipment including the operating condition of solid particle caustic slurry, as the moving ring seat is rotated with an axle, the pressure difference of the axial flow blade is produced on the moving ring seat, and a flow field is formed in the omni-open sealing box, which avoids that as the caustic slurry is deposited in the sealing cavity, the mechanical seal is abated. As the flushing liquid is not required in the sealing operation, the water resource is saved.
Description
Technical field
The utility model belongs to mechanical seal device, relates in particular to the blade-carrying integrated mechanical sealing of rotating seat on a kind of rotating equipment that is applicable to abrasion slip operating mode.
Background technique
Adopt the technology of mechanical seal ripe in oil, chemical industry and sewage treatment and municipal engineering field at Korrosionsmedium.Still unresolved in the industry for a long time for the mechanical seal that contains the solid particle slip, contain the sedimentation of solid particle slip in sealing and cause sealing failure owing to mechanical seal can't overcome, rotating equipment is leaked cause working environment to pollute.
The model utility content
Main purpose of the present utility model is to overcome above-mentioned technological deficiency, and provide a kind of rotating seat blade-carrying integrated mechanical sealing, be applicable to the mechanical seal on the rotating equipment that contains solid particle erosion slip operating mode, solved contain the solid particle slip in sealing sedimentation and cause the problem of seal failure.
For realizing the purpose of this utility model, the technological scheme that adopts is, the blade-carrying integrated mechanical sealing of a kind of rotating seat, it is characterized in that: mainly contain full open type sealed case, sealing carries axle sleeve, the rotating ring assembly, stationary ring assembly and limiting board, described stationary ring assembly mainly contains stationary seat, stationary ring, wherein stationary seat is affixed with full open type sealed case, stationary ring is by sealing gasket and stationary seat pin joint, described limiting board is plugged in the annular groove of spring socket sleeve one end, described rotating ring assembly mainly contains rotating ring, the rotating seat and the spring socket sleeve of band blade, rotating ring is by the rotating seat front-end face pin joint of sealing gasket with the band blade, spring socket sleeve is sleeved on sealing, and to carry the axle sleeve screwing affixed, another interior edge face of spring socket sleeve is provided with some spring eyes, in spring eye, be equipped with spring, spring socket sleeve is an one with the rotating seat pin joint of band blade, and described stationary ring end face and rotating ring end face are end face seal by spring and fit.
Blade shape on the described rotating seat is axial flow, mixed-flow or centrifugal.
The die cavity geometrical shape of described sealed case is cylindrical, taper shape or circular arc.
The beneficial effects of the utility model are the mechanical seal that is applicable on the rotating equipment that contains solid particle erosion slip operating mode, rotating seat rotates the axial blade that makes on the seat with axle and produces pressure reduction, in full open type sealed case, form the flow field, avoid carrying abrasion slip sedimentation in Seal cage to cause mechanical seal to be lost efficacy.Need not add washing solution during seal operation, effectively save water resources.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Please refer to accompanying drawing, the blade-carrying integrated mechanical sealing of a kind of rotating seat, it is characterized in that: mainly contain full open type sealed case 15, sealing carries axle sleeve 1, the rotating ring assembly, stationary ring assembly and limiting board 13, described stationary ring assembly mainly contains stationary seat 11, stationary ring 10, wherein stationary seat 11 is affixed by bolt 14 with full open type sealed case 15, stationary ring 10 is by L grommet type seal 16 and stationary seat 11 pin joints, described limiting board 13 is plugged in the annular groove of spring socket sleeve 6 one ends, described rotating ring assembly mainly contains rotating ring 2, the rotating seat 3 and the spring socket sleeve 6 of band blade 20, rotating ring 2 is by the rotating seat 3 front-end face pin joints of L grommet type seal 17 with the band blade, spring socket sleeve 6 is sleeved on sealing and carries on the axle sleeve 1 affixed with Cock screw 9, spring socket sleeve 6 another interior edge faces are provided with some spring eyes, in spring eye, be equipped with spring 5, spring socket sleeve 6 is one with the rotating seat 3 of band blade 20 by pin 8 pin joints, and the blade 20 on the described rotating seat is shaped as axial flow, mixed-flow or centrifugal.Described stationary ring 10 end faces and rotating ring 2 end faces make both ends of the surface be the sealing fit-state under spring 5 effects.Stationary ring 10 adopts pressureless sintering Carborundum stupalith with rotating ring 2.Axle is equipped with seal ring 4,7,12,18 respectively with each cover place of connection.Its working principle is to adopt full open type sealed case, seal operation cavity 19 directly communicates with the slurry pressure chamber 21 of main frame, do not establish any throttling or isolation mounting in the middle of two cavitys, the die cavity geometrical shape is cylindrical, taper shape or circular arc, so make the solid particle that is difficult for around the seal face in the deposition slurry.Being fixed on rotating seat that the spring socket sleeve 6 on the running shaft drives the band blade with rotation is solidified as a whole produces pressure reduction when it rotates with axle, between the rotating seat of full open type sealed case and band blade, form the flow field, take away the heat of friction pair generation and make not sedimentation of solid particle and accumulation in the slurry, simultaneously because stationary ring 10 end faces are both ends of the surface with rotating ring 2 end faces under spring 5 effects is tightly connected, reaches the effect that seals running shaft.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
