Abstract
The utility model relates to a modified general mechanical seal with integrated mechanical sealing performance, which comprises a shaft, a mechanical sealing gland, a rotating mechanical seal ring and a static mechanical seal ring. The modified general mechanical seal is characterized in that a shaft sleeve is sleeved at the mounting position of the mechanical seal on the shaft, a positioning end surface in the middle of the shaft sleeve corresponds to the mechanical seal gland, the rotating mechanical seal ring and the static mechanical seal ring, the shaft sleeve on the outer side of the mechanical seal gland is provided with positioning screw holes, a connecting shaft is fixed in the positioning screw hole, a sealing groove is arranged below the shaft sleeve on the inner side of the rotating mechanical seal ring, and an O-shaped seal ring arranged in the sealing groove corresponds to the shaft. Besides, the positioning screw holes arranged on the shaft sleeve are distributed uniformly and radially, and the shaft sleeve is provided with scale marks which have eleven and are distributed at intervals of 1mm. The modified general mechanical seal has the advantages of having dual adjustment functions, high installation precision, low loss and long service life and capacity of designing the mechanical seal gland and connectors optionally according to requirements.
Description
Technical field
The utility model relates to a kind of mechanical seal, particularly a kind of modified type conventional machinery sealing with integrated mechanical sealing performance.
Background technique
In a very long time, the motive sealing machinery equipment of require adjusting rotor-position and being not easy to install mechanical seal generally all is to use packing seal, this helps installing adjustment requirement and the low price of changing and being adapted to rotor, but progress and development along with mechanical sealing technology, mechanical seal serviceability temperature and working pressure are more and more higher, price is more and more cheap, and leak few, environmental protection, therefore can be competent at the out of use high pressure of packing seal fully, high temperature and the occasion that environmental requirement is arranged are so mechanical seal is more and more adopted in the sealing of above-mentioned machinery equipment.Conventional machinery sealing highly versatile, low price, easily purchase, but nose balance is less, and in some structure, be not easy to install and change, more improper use is in some specific applications.And use integrated mechanical sealing to cost an arm and a leg, and interfaces such as flushing, Seal cage relief opening to be that manufactory is fixing produce, so dumb.Sometimes heavy axle or major axis just need in order to handle the position that mechanical seal is installed to carry, numerous and diverse processing is prepared and bigger handling machine equipment, cause cost very high even sometimes cannot handle.Simple in structure, easy to process, precision advantages of higher that optical axis has, but we usually change multidiameter shaft into or do not stint the structure that changes other parts and reduce the complete machine performance and guarantee to be optical axis in order to select mechanical seal.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above in the prior art, a kind of modified type conventional machinery sealing with integrated mechanical sealing performance is provided, a kind of modified type conventional machinery sealing of the utility model design with integrated mechanical sealing performance, comprise axle, mechanical seal cover, mechanical sealing linkage ring, mechanical sealing static ring, it is characterized in that: mechanical sealing part is installed on axle is with an axle sleeve, the corresponding mechanical seal cover of the positioning end face at the middle part of axle sleeve, mechanical sealing linkage ring, mechanical sealing static ring, on the axle sleeve in the outside of mechanical seal cover, offer positioning screw hole, the Cock screw coupling shaft is arranged in positioning screw hole, below the axle sleeve of mechanical sealing linkage ring inboard, seal groove is arranged, the O RunddichtringO is arranged in the seal groove corresponding to axle.The positioning screw hole of offering on axle sleeve radially evenly distributes.On axle sleeve, offer graduation line.The graduation line of offering on axle sleeve has 11, and it is spaced apart 1 millimeter.The utility model has the advantages that 1, have dual adjustment function.Immediate shipment timing axle can axially move in axle sleeve arbitrarily, has adjustment capability fully freely, assembling finishes the back by set screw hole on the above-mentioned requirements spooling and fixing, can utilize screw hole can adjust 7mm under no longer urgent prerequisite of deciding screw hole in the using process.2, have and install and change advantage easily.All positioning screwns all are to install in free situation or cavity outside during installation, are not subjected to spatial constraints substantially, only need take mechanical seal cover during replacing apart just with its whole taking-ups.3, installation precision height, the loss of mechanical seal are few, the life-span is long.Utilize dual adjustment function can adjust the impacting force of mechanical seal at any time, its friction pair is operated in the optimal environment.4, all need not consider to install the problem of mechanical seal at aspects such as the design of axle, processing, heat treatments, all are all excessively realized by this less part of axle sleeve.5, low price, part are easily bought and can be designed mechanical seal cover and interface as requested arbitrarily.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Accompanying drawing 1 is a structural representation of the present utility model; Accompanying drawing 2 is a graduation line schematic representation of the present utility model;
Embodiment
Comprise axle 1, mechanical seal cover 2, mechanical sealing linkage ring 3, mechanical sealing static ring 4, it is characterized in that: mechanical sealing part is installed on axle 1 is with an axle sleeve 5, the corresponding mechanical seal cover 2 of the positioning end face at the middle part of axle sleeve 5, mechanical sealing linkage ring 3, mechanical sealing static ring 4, on the axle sleeve 5 in the outside of mechanical seal cover 2, offer positioning screw hole 6, Cock screw 7 coupling shafts 1 are arranged in positioning screw hole 6, below the axle sleeve 5 of mechanical sealing linkage ring 3 inboards, seal groove 8 is arranged, O RunddichtringO 9 is arranged in the seal groove 8 corresponding to axle 1.The positioning screw hole of offering on axle sleeve 56 radially evenly distributes.On axle sleeve 5, offer graduation line 10.The graduation line of offering on axle sleeve 5 10 has 11, and it is spaced apart 1 millimeter.
By above-mentioned requirements manufacturing machine sealing gland 2 and axle sleeve 5.Earlier mechanical seal is installed during assembling and be fixed on the axle sleeve 5 that O RunddichtringO 9 is housed, again it is installed on the axle 1 and puts mechanical seal cover 2, adjust the position of axle 1 then, get final product by the positioning screw hole on the above-mentioned requirements spooling 16 and with Cock screw 7 tightenings at last.Only need release mechanism sealing gland 2 and axle sleeve 5 and the Cock screw 7 of axle 1 just can split out fully during dismounting.The process that re-uses is adjusted as required and finished, and is just passable with 6 tightenings of nearest positioning screw hole.(positioning screw hole 6 can be only made a call in the small-sized machine sealing on axle sleeve 5, directly be fastened on the axle 4 that does not have the tightening hole with Cock screw 7.)
The utility model is mainly used in require to adjust the rotor axial position and be not easy to install the motive sealing machinery equipment of conventional machinery sealing and be inconvenient to and changes mechanical seal and be inconvenient to handle in the structure at the mechanical position of installation, also can be applied to structural design and be the occasion that optical axis still cannot selection standard mechanical seal model; Such as condensate pump, vertical multi-stage Piping Centrifugal Pumps, the pump of opening (half-open) formula impeller, slag stock pump etc.
