Abstract
The utility model provides a container type mechanical sealing, which assembles all components as one component which can be arranged on a shaft, and the utility model can work after tightening screws, wherein a moving ring 6 is embedded on a moving ring seat 4, a spring 17 is arranged in the moving ring seat 4, the spring and the moving ring seat can both be sealed by a moving ring sealing ring 3 and a shaft sleeve 2, and a rotating part can be formed by the fixing ring 14 and fastening screws 16. A static ring 8 is arranged on a pressing cover 10 via a static ring sealing ring 9 so as to form a stationary part. The moving ring 6 and the static ring 8 are in surface contact and can relatively move. The utility model is characterized in that the inner side of the pressing cover 10 is a built-in type in a sealing cavity, and the fastening screws 16 are arranged outside the pressing cover 10, namely out of the sealing cavity.
Description
The utility model belongs to the mechanical seal field, specifically a kind of fluid machineries such as centrifugal pump, blower fan, reactor that are applied to, a kind of envelope that stops fluid to leak outside.
Common mechanical is sealed in the axle of fluid machinery and goes up palpus cleaning when installing, measures, and part of a part is installed, adjusted then, and it is loaded down with trivial details to work, and the amount of labour is big.
The purpose of this utility model then is the problem that exists at above-mentioned prior art, provide a kind of parts of all part assemblings becoming, then these parts are loaded on the axle, tighten screw and get final product work, be suitable for quick maintenance, easy-to-install integrated mechanical sealing.
The purpose of this utility model can reach by following measure:
A kind of integrated mechanical sealing, comprise that rotating ring, stationary ring, compensation mechanism, seal ring form, wherein be rotating ring 6 inserts on rotating seat 4, spring 17 is loaded in the rotating seat 4, and seal, and form rotatable parts by retaining ring 14, Cock screw 16 by seal ring of moving ring 3 and axle sleeve 2; Stationary ring 8 is loaded on the gland 10 by stationary ring seal ring 9 forms static part; Rotating ring 6 contacts with 8 of stationary rings, and does relative movement, it is characterized in that in Seal cage, and gland 10 inboards are built-in type, and fastening screw trip bolt 16 is rotating part fixedly, and in gland 10 outsides, promptly outside the Seal cage.
The utility model has following advantage compared to existing technology:
1, gland is a waist shape gland.
2, with the encapsulation screw retaining ring and axle sleeve are fixed.
3, spring places in the rotating seat, does not contact with fluid during work, and the protection spring is not subjected to flow-induced corrosion.
4, sealing surface has the partial relief effect, is balanced mechanical seal.
5, whole parts all give and being fitted together, and are convenient to manufactory and ensure the quality of products, and have saved disputing over trifles of manufactory and user.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model gland side schematic view.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is made up of parts such as rotating ring 6, axle sleeve 2, stationary ring 8, spring 17, glands 10.Sleeve sealing circle 1 is the sealing between axle sleeve 2 and the axle, rotating ring 6 inserts and are sealed by seal ring of moving ring 3 and axle sleeve 2 on rotating seat 4, and driving pin 5 drives rotating rings 6 and rotates, spring 17 is installed in the rotating seat 4, forms rotatable parts by retaining ring 14, Cock screw 16 and rotates with the axis.One circle screw is arranged on the retaining ring 14, be Cock screw 16, positioning block screw 12 and encapsulation screw 15, wherein Cock screw 16 passes retaining ring 14 and axle sleeve 2 is fixed in retaining ring 14 and axle sleeve 2 on the axle, positioning block screw 12 is fixed on positioning block 13 on the retaining ring 14, and encapsulation screw 15 dress retaining rings 14 are fastened on and make it on the axle sleeve 2 to rotate with axle sleeve 2.And stationary ring 8, gland 10 are loaded on the stuffing box, by stop pin 11 anti-rotations, as static part, and stop fluids to leak outside by stationary ring seal ring 9 and pad 7.Positioning block 13 has fixing size, between gland 10 and retaining ring 14, with the gap between stationary gland 10 and the retaining ring 14, positioning block 13 is fixed on the retaining ring 14 by positioning block screw 12 before installation, and installation is taken off positioning block 13 and positioning block screw 12 after finishing.Rotating ring 6 and stationary ring 8 are the main obturators of these parts, and do relative movement, and in Seal cage, gland 10 inboards are built-in type, and fastening screw trip bolt 16 is in gland 10 outsides, promptly outside the Seal cage.
This structure fits together whole parts by axle sleeve 2, gland 10, encapsulation screw 15 is used for component package, prevent dismounting, with positioning block 13 and positioning block screw 12 levelling springs 17 active lengths, removing positioning block 13 during work can turn round in work, maintenance, replacing to mechanical seal are all convenient, and are easy to install.
Claims (2)
