The mechanical sealing stationary ring device comprises a rotary pressure cover, a stationary ring, a stationary ring seat and a stationary ring sealing ring, a plurality of U-shaped bolt holes are evenly arranged in the rotary pressure cover which is also provided with a conical groove and can randomly rotate by matching the conical groove thereof and a conical lug boss of the stationary ring seat, and the mechanical sealing stationary ring device is mounted in any position of a base. The utility model has good sealing effect, convenient dismounting, simple manufacture, low price and wide market prospects.
Description
Technical field
The utility model relates to a kind of mechanical seal device.
Background technique
Full-fledged along with the modern mechanical seal arrangement, the application of mechanical seal more and more widely.Mechanical seal is by a pair of or several the end face of making slide relative perpendicular to axle is kept down fitting and is equipped with auxiliary seal and reaches the gland seal device of resistance leakage in elastic force (or magnetic force) effect of hydrodynamic pressure and compensation mechanism.The conventional machinery sealing configuration, be made up of elements such as stationary ring (stationary ring), rotating ring (rotating ring), elastic element, spring seat, Cock screw, rotating ring auxiliary seal ring and stationary ring auxiliary seal rings, stop pin is fixed on the gland to prevent that stationary ring from rotating.Whether rotating ring and stationary ring can have the nose balance ability according to them toward contact is called compensated loop or uncompensated ring.Mechanical seal and soft packing seal relatively have following advantage: the sealing reliability height, and macrocyclic in service, sealing state is very stable, and leakage rate is very little, and by rough Statistics, its leakage rate is general only to be 1/100 of soft packing seal; Long service life generally can reach 1～2 year or the longer time in oil, water class medium, also can reach more than half a year usually in chemical medium; Friction horsepower consumes little, and the friction horsepower of mechanical seal only is 10%～50% of soft packing seal, and axle or axle sleeve are not subjected to abrasion basically; Service cycle is long, can compensate automatically behind the end wear, generally speaking, does not need regular maintenance; Good anti-vibration, insensitive to vibration, beat and the axle of running shaft to the deflection of Seal cage; Applied widely, mechanical seal can be used for low temperature, high temperature, vacuum, high pressure, different rotating speeds, and various Korrosionsmedium and contain the sealing of abrasive particle medium etc.But its shortcoming has: structure is complicated, to making the processing request height; Installation is cumbersome with replacing, and requires the workman that certain mounting technique level is arranged; When the contingency accident takes place, handle difficulty; The one-time investment height.Problem particularly easy for installation and disassembly make us pay close attention to.So solving installation is the emphasis of field of sealing technology scientific research with the dismounting problem always.
Summary of the invention
For addressing the above problem, the utility model provides a kind of mechanical seal device, and this device can reach installs and change purpose simply and easily.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of mechanical seal device, comprise mechanical sealing static ring device, mechanical sealing linkage ring device, rotating shaft, described mechanical sealing static ring device and mechanical sealing linkage ring device are enclosed within the rotating shaft, described mechanical sealing static ring device comprises rotary gland, stationary ring, stationary seat, stationary ring seal ring, described rotary gland poor matches with the cone boss of stationary seat so that its taper is recessed, stationary ring be installed in the stationary ring of stationary seat poor in and the stationary ring seal ring is installed in the sealing of stationary seat is pickled with grains or in wine.
For easy accessibility, described rotary gland matches with the cone boss of stationary seat with recessed being pickled with grains or in wine of its taper.
For easy for installation, five equilibrium has the plurality of U-shaped bolt hole on the described rotary gland.
For making better, the convenient disassembly of sealing effect, the span of the recessed poor taper angle theta of described taper is 0～10 °.
The utility model good sealing effect, easy accessibility, manufacturing are simple and cheap, have good market prospects.
