Description
Technical field
What the present invention relates to is mechanical seal device, particularly
pump is usedthe cooling body of mechanical seal device.
Background technique
Mechanical seal can produce frictional heat and heat of stirring in the running, if these heats shed not in time can affect the usability of mechanical seal, therefore needs to take corresponding cooling method to come to lower the temperature to mechanical seal.Cooling scheme conventional single mechanical end face seal is had, the gland of mechanical seal offers pass liquid hole respectively, by the built-in pumping ring in mechanical seal chamber by the medium transport of gland inner chamber to external heat exchanger, after heat exchange, return gland inner chamber again.In this cooling scheme, the circulating effect quality of cycling mechanism to cooling liquid has a great impact cooling effect.
The cooling body of current mechanical seal device as shown in Figure 1, comprise gland 1, static components 2, moving ring assembly 4, pumping ring 6, gland 1 offers circulating liquid outlet 7, circulating liquid entrance 8, static components 2 is arranged on gland 1, moving ring assembly 4 is arranged on axle or axle sleeve and rotates with axle, the friction ring of moving ring assembly 4, the friction ring of static components 2 rotates to coordinate and forms mechanical seal, on the tailstock that pumping ring 6 is fixedly connected on moving ring assembly 4, follow-up ring assembly rotates together, the circulating liquid outlet 7 that the corresponding gland 1 of the outer portion of pumping ring 6 is offered coordinates with gland 1 inner chamber anchor ring and forms centrifugal pumping mechanism, medium pump in mechanical seal cover 1 inner chamber E is delivered to the heat exchanger that equipment (pump) arranges outward and carry out recuperated cycle, make medium continuous cycle heat exchange between mechanical seal cover 1 inner chamber E and heat exchanger.
Its shortcoming of the prior art is, owing to limiting by equipment (pump) external structure, as suspension opening direction or the restriction of arranging that handles money of outside, the circulating liquid outlet 7 that gland 1 is offered and circulating liquid entrance 8 are generally mutually be into 90 or 180 or 270 degree of angles to distribute and offer, under the effect of pumping ring 6, circulating liquid enters into from entrance 8 and flows out from outlet 7 like this, the cooling circulation liquid entering mechanical seal cover inner chamber E can only to flow 1/4 or 1/2 or 3/4 circle at mechanical seal cover inner chamber E, there is 3/4 or 1/2 or 1/4 circle ' dead band ', it is short that the cooling circulation liquid entering mechanical seal cover inner chamber E flows through path, medium circulation in mechanical seal cover inner chamber E is insufficient, the cooling effect of impact to mechanical seal cover inner chamber E.
Summary of the invention
The object of the invention is to improve for above-mentioned the deficiencies in the prior art, a kind of cooling body of mechanical seal device of good cooling results is provided.
The cooling body of mechanical seal device of the present invention, comprise gland 1, static components 2, moving ring assembly 4, pumping ring 6, gland 1 offers circulating liquid outlet 7, circulating liquid entrance 8, static components 2 is arranged on gland 1, moving ring assembly 4 is arranged on axle or axle sleeve and rotates with axle, friction ring and the friction ring of static components 2 of moving ring assembly 4 rotate to coordinate and form mechanical seal, on the tailstock that pumping ring 6 is fixedly connected on moving ring assembly 4, follow-up ring assembly rotates together, the circulating liquid outlet 7 that the corresponding gland 1 of the outer portion of pumping ring 6 is offered coordinates with gland 1 inner chamber anchor ring and forms centrifugal pumping mechanism, it is characterized in that, offer groove 60 in the middle part circle distribution of the pump anchor ring 61 of pumping ring 6 and form blade 61, labyrinth seal groove 65 is offered respectively in the left and right sides portion of the pump anchor ring 61 of pumping ring 6, 61, the blade of corresponding pumping ring 6 has circulation groove 16 on gland 1 inner ring surface 10, it is not open-minded that the circulating liquid of this circulation groove 16 on corresponding gland 1 exports 7 places, form one and cut off convex gear 15, circulation groove 16 bottom surface, front side of convex gear 15 is opened and exports 7 drainages communicated with circulating liquid and portal 7 ', on gland 1 inner ring surface 10, have in the rear lateral portion (turn to pumping ring 6 and determine direction) near circulating liquid entrance 8 axis communicated with circulation groove 16 and enter liquid groove 17, circulation groove 16 is communicated with the rear lateral portion of circulating liquid entrance 8.
When pumping ring 6 follow-up ring assembly 4 of the present invention rotates, medium in circulation groove 16 produces flowing under pumping ring 6 with the acting in conjunction of its blade 61, medium not only under centrifugal action from drainage portal 7 ' flow out, and medium is subject to convex gear 15 and stops when circulation groove 16 flows, under pressure to drainage portal 7 ' flow out, improve the pumping capacity of pumping ring 6.Medium simultaneously in mechanical seal cover inner chamber E, revolution is produced under the effect of pumping ring 6, medium in circulation groove 16 enters liquid groove 17 by the axis communicated with circulation groove 16 and supplements, and axially enter the rear lateral portion that liquid groove 17 is opened in close circulating liquid entrance 8, after the cooling medium entering mechanical seal cover inner chamber E like this from circulating liquid entrance 8 runs nearly one week in mechanical seal cover inner chamber E, circulation groove 16 is entered again from entering liquid groove 17, no matter circulating liquid outlet 7 and the circulating liquid entrance 8 offered at gland 1 are mutually into 90 or 180 or 270 degree of angles to distribute and offer, after the cooling medium entering mechanical seal cover inner chamber E from circulating liquid entrance 8 all must run nearly one week in mechanical seal cover inner chamber E, circulation groove 16 is entered again from entering liquid groove 17, there is not 3/4 or 1/2 or 1/4 circle ' dead band ', the cooling circulation liquid entering mechanical seal cover inner chamber E flows through path length, abundant to the medium circulation in mechanical seal cover inner chamber E, substantially increase the cooling effect to mechanical seal cover inner chamber E.
