Abstract
The utility model relates to a clip-on shaft seal device for turning machinery, comprising a spindle sleeves, the first swivel group, the first shaft collar, a cover, the second swivel group and the second shaft collar, and assembling on the spindle of the turning machinery to seal the shaft hole for leakage-proof. By the peripheral region of the second swivel employing the design of stream guidance emargination, wherein the second swivel in the second swivel group is moved with the spindle, the forced circulation stream guidance action is generated from the cooling circulating liquid in the circulation cover with the circulating liquid nonpressurized, and the leakage-proof effect can be assured by the internal pressure of the liquid in the spring counterbalance machinery and the design of the shaft seal device for preassembling and measuring.
Description
The clamping type gland seal device that the design uses about a kind of rotary machine refers to especially a kind ofly can assemble pressure measurement in advance, and can effectively prevent leak of liquid, and possesses active heat removal and the splendid clamping type gland seal device of cool cycles.
As shown in Figure 5, be applied at present as the gland seal device in the rotary machine of the class of pumping, this gland seal device has one and is sheathed on last and moving together with axle (81) axle sleeve (90) of rotary machine (80) axle (81), axle sleeve (90) outside device is fixedly arranged on the axle envelope seat (91) of rotary machine (80) side with sealing axis hole (82) by some bolts relatively, enclosing cover (92) in other end device one same sheathed axle sleeve (90) outside of axle envelope seat (91), and the containing space (93) of the corresponding connection of formation between axle envelope seat (91) and enclosing cover (92), and the change group (94) that device is made up of some changes (941) polyphone in this containing space (93), keep the runner (931) that the cooling circulation liquid circulation is provided between change group (94) and containing space (93), and in axle envelope seat (91), enclosing cover (92) is respectively established at least one perforation (911) (921) that connects from the outside to runner (931), perforation (911) (921) and external cooling circulation liquid pressurized equipment, as the gateway in the cooling circulation liquid turnover gland seal device, and between change (941) and change and axle envelope (91), between enclosing cover (92) and install O shape ring as leakproof.
During use, see also shown in the 5th figure, when the axle (81) of rotary machine (80) is rotated with fluid transfer, by gland seal device in its lateral end seal leakproof, and some changes (941) of gland seal device Intermediate shaft sleeve (90) and change group (94) are with axle (81) rotation, and cooling circulation liquid is entered from the one perforation by pressurized equipment, and the runner of flowing through (931) absorbs its assembly because of after spin friction generates heat, the multiple perforation by another discharged, and reaches the purpose of its sealed against leakage and cooling heat dissipation.
But, though the aforementioned axis seal apparatus provides the device of axle one sealed against leakage and the cooling function of rotary machine, still have following shortcoming in its single unit system design, wherein:
