Description

A kind of cooling flusher of high speed machine sealing
Technical field
The utility model relates to the cooling flushers of mechanical seal more particularly to the cooling of high speed machine sealing to rinse dress It sets.
Background technique
Traditional mechanical seal rinsing type of cooling is divided into interior flushing and outer flushing.Interior rinse utilizes the close of working host Medium is sealed, seal chamber is introduced by pipeline by the outlet end pumped, is drawn by the road again after rinsing cooling;Outer flushing introduces external system The cleaning fluid compatible with sealed medium to seal chamber is rinsed cooling.When the excessively high (turn up of high speed revolution speed When 30000rpm) it is drawn from pump discharge side and rinses cooling liquid hypertonia and can destroy sealing structure, and when revolving speed is excessively high, sealing Rotating ring high speed rotation can motivate contact liq to generate whirlpool to hinder to rinse cooling liquid and seal exchanging for fluid between dynamic and static ring, And then influence is to the cooling flushing effect of sealing;Furthermore because of the high-speed friction of rotating ring and stationary ring, cause calorific value excessive, if cannot Cooling will lead to liquid in sealing surfaces coking or seal structure damage in time.
Summary of the invention
The purpose of the utility model is to provide a kind of cooling flushers of high speed machine sealing.
The utility model is a kind of cooling flusher of high speed machine sealing, includes inlet tube 1, sparge ring 2, spray-hole 2a, ring baffle 2b, sealed support 4, axis 6, floating carbon ring seal the 7, first liquid back pipe 8, stationary ring bracket 9, stationary ring 10, rotating ring 11, the second liquid back pipe 13, restrictor ring 14, rotating ring 11 and axis 6 are fastenedly connected and can rotate with axis 6, constitute rotor part;Stationary ring 10 It is fixed on stationary ring bracket 9 by spring, is connect with rotating ring 11 by the pair that rubs;Floating carbon ring sealing 7 and stationary ring bracket 9 are solid It is scheduled on sealed support 4;Entire seal assembly is fixed on shell;Restrictor ring 14 is fixed on shell;Sparge ring 2 is fixed on shell On body.
Compared with the background art, what is had has the advantages that the utility model: the utility model is in traditional sealing knot Sparge ring 2 is increased on the basis of structure, injection is flooded in formation, and coolant liquid rinses coolant seal surface, and it is cold to accelerate sealing surfaces circulation But the flow velocity of liquid changes the cooler environment in seal chamber, to guarantee stable operation and the longer life of sealing;And in sparge ring Increase ring baffle 2b in 2 structures, eliminates moving sealing ring 11 and motivate the whirlpool of surrounding liquid formation to the shadow of 2 jet stream of sparge ring It rings, and the top of rotating ring 11 close to stationary ring end is changed to the conical surface, that accelerates groove liquid and coolant liquid between dynamic and static ring exchanges speed Degree, to reach ideal cooling effect.

Specific embodiment
As shown in Fig. 1~Fig. 6, the utility model is a kind of cooling flusher of high speed machine sealing, includes inlet tube 1, sparge ring 2, spray-hole 2a, ring baffle 2b, sealed support 4, axis 6, floating carbon ring seal the 7, first liquid back pipe 8, stationary ring branch Frame 9, stationary ring 10, rotating ring 11, the second liquid back pipe 13, restrictor ring 14, rotating ring 11 and axis 6 are fastenedly connected and can rotate with axis 6, constitute Rotor part;Stationary ring 10 is fixed on stationary ring bracket 9 by spring, is connect with rotating ring 11 by the pair that rubs;Floating carbon ring sealing 7 It is fixed on sealed support 4 with stationary ring bracket 9;Entire seal assembly is fixed on shell;Restrictor ring 14 is fixed on shell;Spray Ring 2 is penetrated to be fixed on shell.
As Figure 1 and Figure 4, sparge ring 2 is equipped with ring baffle 2b.
As Figure 1 and Figure 4, spray-hole 2a is opened up on sparge ring 2, number is 8 ~ 16.
As shown in Figure 2, Figure 4 shows, spray-hole 2a, the axis of the center line OO ' and spray-hole 2a of sparge ring 2 are opened up on sparge ring 2 Line O1O2Angle theta is 120 ° ~ 150 °.
As Figure 1 and Figure 4, sparge ring 2 is equipped with ring baffle 2b, and end face development length is no more than spray-hole 2a The extended line AB of center line, end face corner cut ∠ ABC are consistent with spray-hole 2a tiltangleθ.
As shown in Fig. 1, Fig. 5, Fig. 6, cone structure is used at the top of rotating ring 11, taper is 0 ~ 30 °.
As shown in Figure 1, entire seal assembly is fixed on shell by hexagon socket head cap screw 3.
As shown in Figure 1, restrictor ring 14 is fixed on shell by socket cap screw.
As shown in Figure 1, sparge ring 2 is fixed on shell by countersunk head soket head cap screw 12.
As shown in Fig. 1 ~ Fig. 6, a kind of high speed machine of the utility model seals cooling flusher, include oil inlet pipe 1, Sparge ring 2, spray-hole 2a(at least 16), ring baffle 2b, hexagon socket head cap screw 3, sealed support 4, hexagon socket head cap screw 5, axis 6, floating carbon ring seals the 7, first liquid back pipe 8, stationary ring bracket 9, stationary ring 10,12, second times rotating ring 11, countersunk head soket head cap screw liquid Pipe 13, restrictor ring 14.Rotating ring 11 is close to axis 6, is rotated with axis 6, and rotor part is constituted.Stationary ring 10 passes through the bullet on stationary ring bracket Spring pressing is on rotating ring 11.Floating carbon ring sealing 7 and stationary ring bracket 9 are fixed on sealed support 4 by hexagon socket head cap screw 5.It is whole A seal assembly is fixed on shell by hexagon socket head cap screw 3.Restrictor ring 14 is fixed on shell by socket cap screw On.Sparge ring 2 is fixed on shell by countersunk head soket head cap screw 12.
The course of work of the utility model is as follows: sealing uses two seals, and first is that single end face little spring is static Type mechanical seal mechanical seal, second are floating carbon ring sealing.When seal operation, fluid is right into sparge ring 2 through oil inlet pipe 1 Seal assembly is rinsed cooling, floods injection to be formed, and accelerates the flow velocity of sealing surfaces circulating cooling liquid, changes seal chamber Interior cooler environment, to guarantee stable operation and the longer life of sealing;Simultaneously flow through the fluid of rear bearing through restrictor ring 14 into Enter seal chamber to accelerate to rinse the circulation rate of cooling system, coolant liquid finally returns to express pump through the second liquid back pipe 13 in seal chamber Import, under high temperature, high speed, this, which is sealed with, has micro-leakage, and the medium of outer leakage is stopped by floating carbon ring sealing 7 to real Existing zero leakage.When rotating ring 11 works in seal assembly, surrounding liquid can be motivated to form huge whirlpool in seal chamber, seriously affected Sparge ring 2 floods the effect of spray cooling, therefore when design 2 structure of sparge ring, making it, there are ring baffle 2b above rotating ring 11 Caused whirlpool is motivated by rotating ring 11 to destroy, and 11 top of rotating ring is changed to the conical surface close to 10 end of stationary ring, is accelerated dynamic The exchange velocity of groove liquid and coolant liquid between stationary ring, to reach ideal cooling effect.
