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:
