Abstract
The utility model provides a vapor-liquid full flow screw power machine mechanical seal device, which comprises a moving ring (1) disposed on a rotor shaft (5) or a shaft sleeve (51), a corrugated pipe compensation static ring (2) disposed at the left side of the moving ring (1), and a spring compensation radial dual end face static ring (3) disposed at the right side of the moving ring. The utility model is characterized in that an axial dual end face mechanical seal mechanism and a radial dual end face mechanical seal mechanism are formed. The utility model has advantages of possessing simple structure and long service life, improving the work reliability of a friction sealing end face.
Description
Technical field
The utility model relates to the mechanical device that is converted to power with steam or liquid or vapour-liquid mixed medium, i.e. steam-water helical screw power machine, particularly its mechanical seal device.
Background technique
Steam-water helical screw power machine comprises that casing, a pair of helical rotor that is rotatably assorted mutually, mechanical seal device, synchromesh gear, low voltage terminal seat, high voltage terminal seat constitute, intermeshing helical rotor is installed in the casing, the synchromesh gear of helical rotor axle, bearing, mechanical seal device are installed in respectively in low voltage terminal seat, the high voltage terminal seat, offer the admission mouth of pipe and steam outlet pipe mouth respectively at the casing two ends.High pressure carbonated drink is entered by steam inlet, and the effect helical rotor rotates, and is discharged by steam ouput again, and pressure medium is converted to power output.
Mechanical seal is the critical component of screw power machine and unique easily damaged parts, and its quality directly influences applying and working life and repair cycle of this equipment.What the mechanical seal for axle of prior art screw power machine adopted is a kind of spring axial double mechanical seal device, shown in accompanying drawing 2, it is by being installed in spring compensation rotating ring b, the c on the moving ring sleeve a and constituting with rotating ring b, stationary ring d, the e that c matches of spring compensation respectively, forming spring axial double mechanical seal device.This mechanical seal device working environment medium is high temperature, high pressure steam or hot water, the spring of mechanical seal device and rubber auxiliary seal ring long period of soaking with contact this medium, because fouling and Temperature Influence spring force are inhomogeneous, and be easy to generate jam, fracture, it is aging after the rubber secondary seal easily is heated, cause mechanical seal compensated loop servo-actuated difference and premature failure, to produce medium or cooling water after the seal failure and enter the Bearing gear chamber of mechanical seal device rear side, cause emulsification of lubricant, have a strong impact on the lubricated of bearing and gear.
The model utility content
The purpose of this utility model is to improve at above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, uses reliably good stability, the mechanical sealing device of vapour-liquid full flow screw power machine of good seal performance.
The utility model steam-water helical screw power machine mechanical seal for axle is made of the spring compensation radial direction double end-face stationary ring 3 on rotating ring 1, the bellows compensation stationary ring 2 that is separately positioned on rotating ring 1 left side and right side, form axial Double End and radial double mechanical seal mechanism, on radial direction double end-face stationary ring 3, communicate and offer drain boles 33, offer drain hole 45,65 in correspondence on the stationary seat 4 and on the end seat 6 with the groove 30 of 32 of outer shroud seal face 31 and interior ring seal faces.
The utility model is simple in structure, long service life, reliable operation.Bellows compensation stationary ring 2 is not owing to there is auxiliary seal, anti-jam ability is strong, the even compensation performance of elastic force is good, mechanical seal device outer shroud waterway is by the bellows heat exchange, and temperature that can effectively reduction sealing medium promptly reduces bellows compensation stationary ring 2 internal ring portion medium temperatures, and make steam medium be condensed into water, reduce the operating ambient temperature of friction pair, improved on friction sealed end face working environment, improved the functional reliability of friction sealed end face.The radial direction double end-face stationary ring 3 on rotating ring 1 right side not only cooperates with rotating ring 1 with wave duct compensation stationary ring 2 and forms axial both-end sealing, prevent that medium from leaking vertically, and radial direction double end-face stationary ring 3 is radially forming the both-end sealing with rotating ring 1, from mechanical seal device outer shroud waterway infiltrate external loop diameter to the cooling water of seal face 31 by groove between radial direction double end and the drain boles discharge that is communicated with this groove, can not mix with lubricant oil by the lubricant reservoir that interior ring radial seal end face 32 enters rear side, prevent to cause emulsification of lubricant, influence the lubricated of bearing and gear.Can judge the working condition of sealing by observing the drain boles discharge capacity in addition, the repair and replacement sealing determines when to select a good opportunity.
