Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, a kind of mechanical seal being applicable to thin film evaporator is provided.
The technological scheme that the present invention is adopted for achieving the above object is: the mechanical seal being applicable to thin film evaporator, comprise rotating ring, interior compensated loop, external compensation ring, inner spring, outer spring, spring seat, described spring seat, interior compensated loop is sleeved on axle sleeve successively, and respectively and between axle sleeve Sealing is installed, between described interior compensated loop and spring seat, inner spring is installed, described external compensation ring set is contained in outside interior compensated loop, therebetween sealing liquid chamber is formed, described spring seat is offered the sealing liquid entrance that communicates with sealing liquid chamber and sealing liquid exports, between described external compensation ring and spring seat, outer spring is installed, and between described external compensation ring outer side surface and spring seat, Sealing is installed, described rotating ring is sleeved on axle, therebetween Sealing is installed, described rotating ring end face and interior compensated loop, the seal face laminating of external compensation ring.
Be provided with flush end transmission screw between described external compensation ring and interior compensated loop, compensated loop and external compensation ring in the clamping of described flush end transmission screw top, bottom is screwed in spring seat.
Between described interior compensated loop and inner spring, throw-out collar is installed.
Sealing between described interior compensated loop and axle sleeve adopts cambridge ring.
Described cambridge ring adopts polytetrafluoroethylmaterial material.
Sealing between described rotating ring and axle adopts cambridge ring.
Described cambridge ring adopts polytetrafluoroethylmaterial material.
Described external compensation ring adopts insert structure.
Feature of the present invention is: adopt inside and outside two cover sealings, without the need to configuring Seal cage, shorten axial installation dimension greatly, and have the Corrosion Protection led, the reliability of sealing is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, rotating ring 2, cambridge ring 3, interior compensated loop 4, external compensation ring 5, outer spring 6, throw-out collar 7, inner spring 8, flush end transmission screw 9, sunk screw 10, axle sleeve 11, spring seat 12, location grab 13, socket head screw 14, oil nozzle 15, distance ring 16, locking plate 17, jump ring 18, nut 19, screw.
Embodiment
As shown in Figure 1, the present invention adopts radial direction double end-face, many springs, state type arrangement, comprise rotating ring 1, interior compensated loop 3, external compensation ring 4, inner spring 7, outer spring 5, spring seat 11, described spring seat 11, interior compensated loop 3 is sleeved on axle sleeve 10 successively, and respectively and between axle sleeve 10 Sealing is installed, between described spring seat 11 and axle sleeve 10, Sealing adopts O type circle and square ring, described spring seat 11 is fixed on axle sleeve 10 by sunk screw 9, between described interior compensated loop 3 and spring seat 11, inner spring 7 is installed, between described interior compensated loop 3 and inner spring 7, throw-out collar 6 is installed, described external compensation ring 4 is sleeved on outside interior compensated loop 4, between described external compensation ring 4 and spring seat 11, outer spring 5 is installed, and between described external compensation ring 4 outer side surface and spring seat 11, Sealing is installed, Sealing adopts O type circle, because the atmospheric side pressure reduction of mechanical seal is larger than side medium pressure reduction, so described external compensation ring 4 adopts insert structure, intensity increases, improve the reliability of sealing, sealing liquid chamber is formed between described interior compensated loop 3 and the radial direction double end-face of external compensation ring 4, described spring seat 11 offers the sealing liquid entrance communicated with sealing liquid chamber and sealing liquid exports, and oil nozzle 14 is installed, sealing liquid is interior, the effect of lubrication is played between outer two cover sealings, thus do not need for seal arrangement Seal cage, shorten axial installation dimension greatly, and between described external compensation ring 4 and interior compensated loop 3, flush end transmission screw 8 is installed, compensated loop 3 and external compensation ring 4 in the clamping of described flush end transmission screw 8 top, bottom is screwed in spring seat 11, thus prevent interior compensated loop 3 and external compensation ring 4 play, described rotating ring 1 is sleeved on axle, therebetween Sealing is installed, described rotating ring 1 end face and interior compensated loop 3, the seal face laminating of external compensation ring 4, namely in, compensated loop 3 and external compensation ring 4 share a rotating ring 1, thus decrease the error installed, add the ability that the anti-footpath of sealing is jumped, the cambridge ring 2 that Sealing between described interior compensated loop 3 and axle sleeve 10 and the Sealing between described rotating ring 1 and axle all adopt polytetrafluoroethylmaterial material to make, thus play etch-proof effect, described rotating ring 1 is connected with locking plate 16 by pin, mechanical seal is by locking plate 16 transmission locking, described locking plate 16 adopts splitted structure, by screw 19, nut 18 connects fastening, and jump ring 17 is installed, at rotating ring 1, distance ring 15 is installed between locking plate 16, described distance ring 15 is sleeved on axle, location grab 12 is installed outside described rotating ring 1, location grab 12 is fixed on spring seat 11 by socket head screw 13.
During use by mechanical connection on thin film evaporator, and jump ring 17 to be loaded in locking plate 16, and fixes inner bolt 19 and nut 18, before driving, disassemble location grab 12 and socket head screw 13, and sealing liquid of first having friendly relations, avoid sealing surface dry friction.
