Description
Technical field
The utility model relates to machining class field, particularly a kind of working machine Sealing.
Background technique
Mechanical seal refers to and under the effect of hydrodynamic pressure and compensation mechanism elastic force and under the cooperation of auxiliary seal, keeps laminating by least one pair of end face perpendicular to spin axis and relative sliding and device that the anti-fluid that forms is leaked.Elastic force load maintainer and auxiliary seal be metallicity line pipe mechanical seal we be called the wavy metal seal of tube.In light seal, also have and use rubber corrugated pipe to make auxiliary seal, rubber corrugated pipe elastic force is limited, generally to need being aided with spring and meets loading elastic force." mechanical seal " usually by people referred to as " machine envelope ".Mechanical seal is a kind of gland seal device of rotating machinery.The equipment such as such as centrifugal pump, centrifuge, reactor and compressor.Because transmission shaft is applied in inside and outside equipment, like this, there is a circumferential clearance between axle and equipment, medium in equipment passes through this gap to external leakage, if equipment internal pressure is lower than barometric pressure, then air is to equipment internal leakage, and one therefore must be had to stop the gland seal device leaked.The kind of shaft seal is a lot, the advantage such as to grow, so mechanical seal is in the topmost shaft sealing mode of these equipment in the world today because mechanical seal has leakage rate few and life-span.Mechanical seal is named end face seal again, is like this definition in relative national standards: " is kept fitting under hydrodynamic pressure and the effect of compensation mechanism elastic force and the cooperation of auxiliary seal by least one pair of end face perpendicular to spin axis and relative sliding and the device of anti-fluid leakage that forms.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of delicate structure, the design of the front and rear covers increased can each part of effective press seal part, the working machine Sealing of the seal of long-acting maintenance Sealing, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technological scheme: a kind of working machine Sealing, by main shaft, compress bonnet, L-type seal ring, stationary ring, rotating ring, O-ring seal, pad, spring, the tight screw of bolt and compression protecgulum composition, compressing bonnet is enclosed within main shaft, L-type seal ring is enclosed within main shaft, press-in compresses in the groove of bonnet, stationary ring is enclosed within main shaft, in the groove of stationary ring press-in L-type seal ring, moving ring sleeve is on main shaft, withstand stationary ring, O-ring seal is enclosed within main shaft, pad is enclosed within main shaft and compresses O-ring seal, spring housing is on main shaft, compressing protecgulum is enclosed within main shaft, holddown spring, by bolt tight screw, compression protecgulum is fixed.
Preferably, the tight screw of described bolt is hexagon nut, is provided with cross bore above.
