Abstract
The utility model provides a mechanical seal transmission device with shaft seal. The mechanical seal transmission device with the shaft seal comprises a moving ring shaft sleeve (1), a transmission ring (3), the shaft seal (2), a clamping ring (4), a set screw (5) and a clamping ring draw-in bolt (7). The mechanical seal transmission device with the shaft seal is characterized in that a seam allowance groove (32) is arranged in the inner ring surface of the transmission ring (3) and matched with the outer end of the moving ring shaft sleeve (1) to form a compressed closed cavity, and soft graphite material shaft seal (2) is arranged in the closed cavity. An anti-rotating pin hole (60) is formed in the matching surface of the clamping ring (4) and the moving ring shaft sleeve (1), and an anti-rotating pin (6) is arranged on the anti-rotating pin hole (60). Sealing function is achieved by squeezing soft graphite, sealing effect and anti-corrosion and anti-high-temperature are good, and reliability of matching transmission of the clamping ring (4) and the moving ring shaft sleeve (1) is good by the anti-rotating pin (6).
Description
Technical field
The utility model relates to mechanical seal device, particularly the sealing transmission joint of the rotating ring axle sleeve of mechanical seal device and axle.
Background technique
At high temperature and having under the aggressive medium condition,
The rotating ring axle sleeve of integrated mechanical seal device and the sealing of between centers are namelyShaft seal can not adopt O shape circle and other cushion rubber, and the structure of seal ring is done in the sealing between pump shaft and the rotating ring axle sleeve usually employing extrusion industry fine aluminium or teflon between axle sleeve and transmission ring.The commercial-purity aluminium temperature tolerance is good, but corrosion-resistant unsatisfactory, and teflon is corrosion-resistant good, but high temperature resistant poor.So cause this integrated form
Mechanical seal deviceVersatility not strong.Aspect transmission, prior art is to lean on fine aluminium or teflon shaft seal banding in the transmission of axle realization axle and rotating ring shaft room power fully in addition, and shaft seal and axle produce the situation of relative sliding easily, affect reliable transmission.
The model utility content
The purpose of this utility model is to improve for the shortcoming of above-mentioned prior art, provide a kind of corrosion resistance and heat-resisting quantity good, and reliable transmission is good
With the rotating ring axle sleeve of the mechanical sealed driving device of shaft seal, particularly integrated mechanical seal device and the sealing transmission joint of axle.
The utility model is with the mechanical sealed driving device of shaft seal, include rotating ring axle sleeve 1, transmission ring 3, shaft seal 2, snap ring 4, Cock screw 5, snap ring turnbuckle 7, it is characterized in that offering rabbet groove 32 at the inner ring surface of transmission ring 3, the trapezoidal rabbet groove 32 that rabbet groove 32 is preferably formed by axial plane 30 and radial 31, outer end with the rotating ring axle sleeve 1 of inner conical surface 10 cooperates with the trapezoidal rabbet groove 32 of transmission ring 3, the trapezoidal rabbet groove 32 of transmission ring 3 cooperates the compressible closed chamber of formation with the outer end of rotating ring axle sleeve 1, in the trapezoidal rabbet groove 32 of transmission ring flexible graphite material shaft seal 2 is set; Fitting surface at snap ring 4 and rotating ring axle sleeve 1 offers anti-rotation pin-and-hole 60, at this anti-rotation pin-and-hole 60 stop pin 6 is set.
The utility model is simple in structure, makes easy.Transmission ring 3 relative prior art transmission structure of rings have increased and the cooperating of rotating ring axle sleeve 1, namely offering trapezoidal rabbet groove 32 at transmission ring 3 makes between rotating ring axle sleeve 1 and transmission ring 3 and pump shaft and has formed confined space, flexible graphite material shaft seal 2 is set in this confined space, reach the effect of sealing by the extruding Expanded graphite, good sealing effect not only, and corrosion resistance and heat-resisting quantity are good, have improved the application power of product, and the product versatility is good.Mill out respectively the semicircle orifice that matches and form anti-rotation pin-and-hole 60 on the fitting surface of snap ring 4 and rotating ring axle sleeve 1, reach snap ring 4 and rotating ring axle sleeve 1 mandatory anti-rotation by settling stop pin 6 to cooperate, avoid producing relative sliding, reliable transmission is good.
