Description

Oil sealing mechanical sealing assembly
Technical field
The utility model relates to sealing element technical field, a kind of specifically oil sealing mechanical sealing assembly.
Background technique
Mechanically-sealing apparatus is by least a pair of end face perpendicular to rotation axis in Fluid pressure and compensation mechanism elastic force Under the action of and the cooperation of auxiliary seal under keep fitting, and the device for preventing fluid leakage constituted with respect to sliding.
Traditional mechanically-sealing apparatus is mainly by: end face seal pair (stationary seal ring and rotary packing ring), elastic element (such as bullet Spring), auxiliary seal (such as O-ring), driving member (such as trundle and transmission screw), rotation preventing device (such as stop pin) and fastener (such as Spring base, throw-out collar, gland, holding screw and axle sleeve) etc. composition.
In use, most of mechanical seals belong to contact seal.Its mechanism be by rotary packing ring with it is quiet close The contact face of seal ring fits closely under the action of sealing-fluid pressure and elastic element pressing force, and reaches with respect to sliding Sealing.Phenomena such as friction, sliding are with abrasion occurs when work, on mechanical seal end surface simultaneously, friction is its essential characteristic.Machine The operating condition of tool seal face friction is generally divided into: fluid friction, mixed film friction and boundary friction three classes, but absolutely cannot be for a long time Dry friction.
When seal face is in dry condition, direct contact is caused play by the surface of solids micro-bulge between both ends of the surface Strong abrasion, usually adds lubricating oil on seal face thus, and there are serious problems for lubricating oil addition manner at present, i.e., with Seal face rotation, lubricating oil can along at the gap between static seal end face and dynamic sealing end face leak, cause lubricating oil Waste.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of oil sealing mechanical sealing assemblies, can effectively prevent dynamic The leakage of lubricating oil between sealing ring and stationary seal ring.
Technical solution adopted in the utility model is: it includes a retainer, is equipped with rotating seat and stationary ring in retainer Seat, retainer are fitted closely by elastic component and stationary seat, are respectively equipped with rotary packing ring and static seal on rotating seat and stationary seat Ring, rotary packing ring and stationary seal ring palette and can be in relative rotation be equipped with sealing ring, move between rotating seat and rotary packing ring Sealing ring outer diameter is equipped with fan, and the end face that rotary packing ring is bonded with stationary seal ring is equipped with two grooves being parallel to each other, phase Ying Di, stationary seal ring end face be equipped with two matched bulge loops being parallel to each other, bulge loop is mutually chimeric with groove, two bulge loops it Between be equipped with oil groove for storing lubricating oil, a protrusion is formed between two grooves, protrusion is located in groove, in groove Raised cross section be it is arc-shaped, groove and convex to form sealing.
Preferably, groove cross section is triangle, and bulge loop cross section is semicircle.
A kind of oil sealing mechanical sealing assembly of the utility model, advantage are as follows: rotary packing ring is bonded with stationary seal ring End face is equipped with two grooves being parallel to each other, correspondingly, what stationary seal ring end face was parallel to each other equipped with matched two Bulge loop, bulge loop is mutually chimeric with groove, the lubricating oil in oil groove between two bulge loops due to bulge loop and groove it is mutually chimeric without It can reveal;Groove cross section is triangle, and bulge loop cross section is semicircle, i.e., has no completely between bottom portion of groove at the top of bulge loop It is chimeric, a closed space is formed, lubricating oil is flow in the space, moreover it is possible to and it is outer without leaking to play storage lubricating oil, Further for the lubrication at bulge loop place chimeric with groove, without will cause lubricating oil waste, a protrusion is formed between two grooves, it is convex Rise and be located in groove, raised cross section in groove be it is arc-shaped, groove and convex to form sealing, raised cross section is to justify Arc not only increases the surface area in oil groove, therefore increases storage capacity of lubricating oil, and facilitates stationary seal ring and move The installation of sealing ring, i.e. arc-shaped convex can play two sealing rings and be fitted into guiding role.
Detailed description of the invention

Fig. 2 is enlarged drawing at A in Fig. 1.
Wherein, 1, retainer, 2, rotating seat, 3, stationary seat, 4, elastic component, 5, rotary packing ring, 6, stationary seal ring, 7, sealing Circle, 8, fan, 9, groove, 10, bulge loop, 11, oil groove, 12, protrusion.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the utility model provides a kind of oil sealing mechanical sealing assembly, it includes a retainer 1, retainer 1 Interior to be equipped with rotating seat 2 and stationary seat 3, retainer 1 is fitted closely by elastic component 4 with stationary seat 3, on rotating seat 2 and stationary seat 3 It is respectively equipped with rotary packing ring 5 and stationary seal ring 6, rotary packing ring 5 and 6 palette of stationary seal ring and can be in relative rotation, rotating ring Sealing ring 7 is equipped between seat 2 and rotary packing ring 5,5 outer diameter of rotary packing ring is equipped with fan 8, and fan 8 is rotated with rotary packing ring 5 And rotate, it radiates for generating heat with 6 relative friction of stationary seal ring to rotary packing ring 5, as shown in Fig. 2, rotary packing ring 5 The end face being bonded with stationary seal ring 6 is equipped with two grooves 9 being parallel to each other, and correspondingly, 6 end face of stationary seal ring is equipped with matches therewith Two bulge loops 10 being parallel to each other closed, bulge loop 10 is mutually chimeric with groove 9, is equipped between two bulge loops 10 for storing lubricating oil Oil groove 11, design corresponding two bulge loops 10 of two grooves 9 here, it is therefore intended that the lubricating oil in oil groove 11 between being located at is let out Leakage, if only opening an independent groove 9 and bulge loop 10, lubricating oil still can leak as time goes by, and two grooves 9 are right Two bulge loops 10 are answered, two confined spaces of formation can further prevent oil leak tight to outside and by lubricating oil Lock the contact surface in confined space, between sufficient lubrication groove 9 and bulge loop 10.
9 cross section of groove is triangle, and 10 cross section of bulge loop is semicircle, so that 9 bottom of groove and 10 top shape of bulge loop At confined space have sufficiently large capacity and contact surface so that flow to the lubricating oil sufficient lubrication groove 9 of the confined space with 10 face of bulge loop.
A protrusion 12 is formed between two grooves 9, protrusion 12 is located in groove 9,12 cross section of protrusion in groove 9 To be arc-shaped, groove 9 and protrusion 12 are formed and are sealed, raised 12 cross sections be it is arc-shaped, not only increase the surface in oil groove 11 Product, therefore storage capacity of lubricating oil is increased, and facilitate the installation of stationary seal ring 6 Yu rotary packing ring 5, i.e. arc-shaped convex 12, which can play two sealing rings, is fitted into guiding role.
The utility model preferred embodiment is described above, but is not to be construed as limiting the scope of the invention. The utility model is not only limited to above embodiments, and specific structure is allowed to vary, all in the utility model demand for independence Made various change is within the protection scope of the present utility model in protection scope.
