Description

Gas electricity generator mechanically-sealing apparatus
Technical field
It the utility model is related to a kind of mechanically-sealing apparatus on gas electricity generator.
Background technology
Mechanical seal is a kind of gland seal device of rotating machinery.For example centrifugal pump, centrifuge, reaction kettle and compressor etc. are set It is standby.Since transmission shaft is applied in inside and outside equipment, in this way, there are a circumferential clearance between axis and equipment, the medium in equipment leads to The gap is crossed to outward leakage, if pressure subatmospheric in equipment, air are revealed into equipment, it is therefore necessary to have a resistance The gland seal device of stopping leak dew.The species of axle envelope is very much, since mechanical seal has the advantages that leakage rate is few and long lifespan, so ought Modern mechanical seal in the world is in the most important sealing mode of these equipment.Mechanical seal is called end face seal, has in country It is defined as in the standard of pass:" by least a pair perpendicular to the end face of rotation axis in Fluid pressure and compensation mechanism elastic force (Or magnetic force)Effect and auxiliary seal cooperation under keep be bonded and formed with respect to slip prevent fluid leak dress Put.”
Gas electricity generator is a kind of using fuel gas such as liquefied gas, natural gases as comburant, instead of gasoline, diesel oil as hair New, the efficient generation of electricity by new energy machine of motivation power.Since gas electricity generator is gaseous medium so that be dry between dynamic and static ring Friction, its abrasion is very fast, greatly reduces the service life of mechanically-sealing apparatus.
Utility model content
In view of this, the utility model provides a kind of gas electricity generator mechanically-sealing apparatus, and flushing water is introduced and is sealed End face forms thin liquid film and is lubricated.
To solve above technical problem, the technical solution of the utility model is to use a kind of gas electricity generator mechanical seal Device, includes the rotating ring and stationary ring of the sealing that cooperates;The rotating ring is fixed on main shaft, and the stationary ring is fixed on pump case; The rotating ring and stationary ring are two groups of front and rear installation, and two rotating rings are arranged on two stationary rings in inner side and are arranged on outside;Two rotating rings Between be provided with the fixed mounting ring being placed on main shaft, described two end faces of mounting ring are provided with rotating seat;Described two rotating rings It is connected in respectively in two rotating seats, and rotating ring rear is provided with the counterbalance spring for pretension;The rotating ring and compensation bullet Throw-out collar is provided between spring;In the rotating ring some grooves, the groove are provided with the seal face of one close with medium The sensible rotating ring outer ring surface in one end.
As an improvement the groove is T-slot.The sensible rotating ring outer ring surface of its one end, in addition both ends it is close to be located at rotating ring In end-blocking face.Flushing water is introduced at the driven torus outer ring surface of T-slot one end, in addition both ends are responsible for flushing water to be distributed to seal face On.
As a kind of further improvement, the groove is located at being provided at both ends with for drainage on ring seal end face Slope.Had a common boundary by slope and seal face, flushing water is inducted into seal face.
As another further improvement, some grooves are distributed along rotating ring even circumferential.
The utility model is beneficial in that:Gas electricity generator mechanically-sealing apparatus with said structure, passes through Flushing water is introduced to the lubrication of seal face formation thin liquid film progress seal face, greatly reduces the abrasion between dynamic and static ring, The service life of mechanically-sealing apparatus is added, improves economic benefit.

Embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to specific implementation The utility model is described in further detail for mode.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model includes the rotating ring 2 and stationary ring 1 sealed that cooperate;The rotating ring 2 It is fixed on main shaft, the stationary ring 1 is fixed on pump case;The rotating ring 2 and stationary ring 1 are two groups of front and rear installation, two rotating rings 2 It is arranged on two stationary rings 1 in inner side and is arranged on outside;The fixed mounting ring 3 being placed on main shaft is provided between two rotating rings 2, it is described 3 two end faces of mounting ring are provided with rotating seat;Described two rotating rings 2 are connected in two rotating seats respectively, and 2 rear of rotating ring It is provided with the counterbalance spring 4 for pretension;Throw-out collar 5 is provided between the rotating ring 2 and counterbalance spring 4;In the rotating ring 2 with Jie Some grooves 6, sensible 2 outer ring surface of rotating ring in 6 one end of groove are provided with the close seal face of one of matter.The groove 6 For T-slot, sensible 2 outer ring surface of rotating ring of its one end, in addition both ends be located in 2 seal face of rotating ring.Groove 6 is located at ring seal end The slope being provided at both ends with for drainage on face.Groove 6 is 6, and is distributed along 2 even circumferential of rotating ring.
When work, rotating ring 2 is with main axis and stationary ring 1 is fixed.Flushing water cools down rotating ring 2 and quiet 1 ring.By In the groove 6 that its sensible outer ring surface is provided with rotating ring 2 so that flushing water enters seal face by groove 6, and is uniformly divided Cloth forms the thin liquid film for lubricating.
It the above is only the preferred embodiment of the utility model, it is noted that above-mentioned preferred embodiment should not regard For the limitation to the utility model, the scope of protection of the utility model should be subject to claim limited range.For For those skilled in the art, without departing from the spirit and scope of the utility model, it can also make some Improvements and modifications, these improvements and modifications also should be regarded as the scope of protection of the utility model.
