The purpose of this utility model provides a kind of suitable pressure can reach 4.0MPa, and shaft (axle sleeve) external diameter can reach 180mm, adopts more reliable packaging type design, and it is time saving and energy saving to install, and can guarantee the mechanically-sealing apparatus of installation quality.
The purpose of this utility model is achieved in that a kind of autoclave integrated mechanical sealing device, is characterized in: the sealing device comprises bottom filling sealing, retaining oil jacket, bottom mechanical seal, middle stationary seat, middle part mechanical seal, double row self aligning spherical roller bearing, goes up seal chamber, top mechanical seal, O-ring seals, goes up stationary seat, locating piece, centring ring, splits snap ring, power transmission shaft, pressurizer, compensator, screw, hand pump, lower seal cavity, stationary seat and axle sleeve down.
Above-mentioned autoclave integrated mechanical sealing device, be characterized in: arranged in series is adopted in the mechanical seal of sealing device, the Seal Oil regulating system control of each seal face load by being made up of pressurizer, compensator and hand pump makes it to remain in the reasonable range.
Above-mentioned autoclave integrated mechanical sealing device, be characterized in: the sealing device adopts centring ring, split snap ring and screw compresses axle sleeve reliably, adopt the relative position of locating piece, and any variation took place in anti-relative position here before installing and using with the dynamic and static part of definite sealing.
Accompanying drawing 1 is a structural representation of the present utility model.
In the accompanying drawing: the sealing of 1-bottom filling; 2-keeps off oil jacket; The mechanical seal of 3-bottom; Stationary seat among the 4-; 5-middle part mechanical seal; The 6-double row self aligning spherical roller bearing; The last seal chamber of 7-; The mechanical seal of 8-top; 9-O shape sealing ring; The last stationary seat of 10-; The 11-locating piece; The 12-centring ring; 13-splits snap ring; The 14-power transmission shaft; The 15-pressurizer; The 16-compensator; The 17-screw; The 18-hand pump; 19-lower seal cavity; Stationary seat under the 20-; The 21-axle sleeve.
The utility model will be further described below in conjunction with accompanying drawing:
The utility model is a kind of autoclave integrated mechanical sealing device, and its structure is seen accompanying drawing 1.The sealing device comprises bottom filling sealing 1, retaining oil jacket 2, bottom mechanical seal 3, middle stationary seat 4, middle part mechanical seal 5, double row self aligning spherical roller bearing 6, goes up seal chamber 7, top mechanical seal 8, O-ring seals 9, goes up stationary seat 10, locating piece 11, centring ring 12, splits snap ring 13, power transmission shaft 14, pressurizer 15, compensator 16, screw 17, hand pump 18, lower seal cavity 19, stationary seat 20 and axle sleeve 21 down.Power transmission shaft 14, go up seal chamber 7, lower seal cavity 19 is assembled into one with bottom mechanical seal 3, middle part mechanical seal 5, top mechanical seal 8, be provided with below the lower seal cavity 19 to prevent the retaining oil jacket 2 that leaks in the Seal Oil and prevent the bottom filling sealing 1 that powder enters seal chamber in the still.The axial restraint of axle sleeve 21, adopt centring ring 12 and split snap ring 13 and tighten screw 17 and realize, two locating pieces 11 are fastening in place after the product export debugging is finished, and its effect is axially to produce excessive relative displacement when limiting the dynamic and static part of a whole set of sealing device in transit with lifting.Last seal chamber 7, lower seal cavity 19 with middle stationary seat 4, go up stationary seat 10, the faying face of stationary seat 20 adopts O-ring seals 9 to guarantee installation accuracy down.In addition, also be provided with the sealing oil pressure regulating system, so that upward annular seal space 7, lower seal chamber 19 interior sealing oil pressures remain within the scope of setting, in order to keep the reasonable load on each mechanical seal end surface.Sealing oil pressure regulating system is made up of pressurizer 15, compensator 16 and hand pump 18 etc.
The utility model compared with prior art has the following advantages: 1, the scope of application enlarges, and annular seal space pressure can Reach 4.0MPa, axle (axle sleeve) external diameter can reach 180mm; 2, be provided with the gear oil jacket of collecting leakage in the Seal Oil, in But leak the Seal Oil regular discharge, pollute to avoid material, improve the quality of products; 3, be provided with the bottom filling sealing, Prevent that powder enters seal chamber in the still, but the life-span of prolonged mechanical sealing also can be prevented what Queensland only in time discharged Interior leakage of oil enters in the still; 4, arranged in series is adopted in mechanical seal, and the load of each seal face is tending towards rationally, Be conducive to prolong the service life of sealing; 5, the faying face between each seal chamber and each stationary seat adopts O shape Circle sealing is conducive to guarantee the installation accuracy that seals; 6, a whole set of sealing not only comprises axle sleeve and seal chamber etc. Parts, but also comprise axle, comprise all sealing installation questions that seal between axle sleeve and the axle thereby solved, Further simplify installment work, improved installation accuracy and the installation quality of sealing; 7, axle sleeve is axially fixed The position design is applicable to the high pressure operating mode, compares with the axial location mode of holding screw, can bear bigger axial force, Avoid axial location to become flexible phenomenon.
