Abstract
The invention relates to a mechanical sealing drive device with a shaft seal. The mechanical sealing drive device with the shaft seal comprises a rotating ring sleeve (1), a drive ring (3), the shaft seal (2), a clamping ring (4), a set screw (5) and a clamping ring tension bolt (7). The mechanical sealing drive device is characterized in that the inner ring surface of the drive ring (3) is provided with a stopping groove (32) matching with the outer end of the rotating ring sleeve (1) to form a compressible sealing cavity, and the shaft seal (2) made of flexible graphite material is arranged in the sealing cavity; and a matching surface of the clamping ring (4) and the rotating ring sleeve (1) is provided with an anti-rotating pin hole (60), and an anti-rotating pin (6) is arranged on the anti-rotating pin hole (60). The flexible graphite is extruded to achieve sealing, sealing effect, corrosion resistance and high temperature resistance are high, and drive reliability is high by matching the clamping ring (4) and the rotating ring sleeve (1) through the anti-rotating pin (6).
Description
Technical field
what the present invention relates to is mechanical seal device, particularly the sealing transmission joint of the rotating ring axle sleeve of mechanical seal device and axle.
Background technique
High temperature with have under the aggressive medium condition,
The rotating ring axle sleeve of integrated form mechanical seal device and the sealing of between centers are promptlyAxle envelope can not adopt O shape circle and other cushion rubber, and the sealing between pump shaft and the rotating ring axle sleeve is employed in the structure that extrusion industry fine aluminium between axle sleeve and the transmission ring or teflon are made seal ring usually.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.In addition aspect transmission, existing technology is to lean on fine aluminium or teflon axle envelope banding on axle, to realize the transmission of axle and rotating ring shaft room power fully, and axle envelope and spool be easy to generate the situation of slide relative influences reliable transmission property.
Summary of the invention
The objective of the invention is to improve to the shortcoming of above-mentioned existing technology; Provide a kind of corrosion resistance and heat-resisting quantity good; And good
of reliable transmission property have the sealing transmission joint of a rotating ring axle sleeve of the mechanical seal transmission device, particularly integrated form mechanical seal device of envelope and axle.
the present invention has the mechanical seal transmission device of axle envelope; Include rotating ring axle sleeve 1, transmission ring 3, axle envelope 2, snap ring 4, Cock screw 5, snap ring turnbuckle 7; It is characterized in that on the inner ring surface of transmission ring 3, offering seam groove 32; The trapezoidal seam groove 32 that seam groove 32 is preferably formed by axial plane 30 and radial 31; The outer end that has the rotating ring axle sleeve 1 of inner conical surface 10 cooperates with the trapezoidal seam groove 32 of transmission ring 3, and the trapezoidal seam groove 32 of transmission ring 3 cooperates the compressible closed chamber of formation with the outer end of rotating ring axle sleeve 1, and flexible graphite material axle envelope 2 is set in the trapezoidal seam groove 32 of transmission ring; On the fitting surface of snap ring 4 and rotating ring axle sleeve 1, offer anti-rotation pin-and-hole 60, on this anti-rotation pin-and-hole 60, stop pin 6 is set.
the present invention is simple in structure, makes easy.The structure of transmission ring 3 relative existing technology transmission rings has increased and the cooperating of rotating ring axle sleeve 1; Promptly make between rotating ring axle sleeve 1 and transmission ring 3 and pump shaft and formed confined space offering trapezoidal seam groove 32 on the transmission ring 3, flexible graphite material axle envelope 2 is set in this confined space, reach the effect of sealing through 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.On the fitting surface of snap ring 4 and rotating ring axle sleeve 1, mill out the semicircle orifice that matches respectively and form anti-rotation pin-and-hole 60, reach snap ring 4 and rotating ring axle sleeve 1 mandatory anti-rotation through settling stop pin 6 to cooperate, avoid producing slide relative, reliable transmission property is good.
