Technical field
The utility model relates to the water hinge and makes the field, relates in particular to a kind of water hinge that adopts mechanical end face seal.
Background technology
Radar water hinge is the web member between radar matrix and the antenna, and it has two functions, the one, transmit liquid coolant to antenna, the 2nd, realize freely rotating of radar antenna, its feature is that the pressure of sealing liquid coolant is low, the hinge rotational speed is slow, require good airproof performance, long service life etc.
The seal form of existing water hinge mainly contains two kinds: a kind of is flexible sealing, and a kind of is mechanical dynamic seal.
Flexible sealing mainly is to seal by rubber ring, and it is simple in structure, and cost is low, but easily wearing and tearing and aging of rubber ring produce and leak, and need often to change O-ring seal.
Mechanical dynamic seal claims again butt-end packing, is the device that a kind of restraint of labour fluid leaks along rotating shaft.Usually formed by stationary ring (stationary ring), swivel eye (rotating ring), elasticity or the parts such as magnetic element, swivel eye driving member and auxiliary seal ring.Two binding faces and auxiliary seal are realized its sealing function in relative rotation to utilize swivel eye and stationary ring during work.Can mechanical seal work and depend on that can both ends of the surface set up stable, reliable lubricating film and in time heat of friction is derived.It is reliable that mechanical dynamic seal has sealing, and leakage rate is little, long working life, end face can auto-compensation, need not the advantages such as often maintenance, shortcoming is high to the processing of seal and assembly precision, and manufacturing cost is high, be difficult for when breaking down taking emergency measures, and the rotating ring of used mechanical seal and stationary ring adopt stupalith, although have wear-resistant, corrosion-resistant, temperature tolerance, on-deformable advantage, ceramic hardness is high, high-precision friction pair difficulty of processing is large, and processing cost is high.
The utility model content
The purpose of this utility model is to address the above problem, a kind of water hinge that adopts mechanical end face seal is provided, and it has advantages of, and sealing is reliable, the friction pair difficulty of processing is little, cost is low, have compensation rate between the friction pair, working condition requirement is low and long working life.
The utility model is by the following technical solutions:
A kind of water hinge that adopts mechanical end face seal, comprise interior ring and in relative rotation water inlet pipe component and return pipe assembly disposed thereon, described water inlet pipe component and described return pipe assembly and described interior ring joint are provided with mechanical end face seal, described mechanical end face seal comprises and the close-fitting stationary ring of described interior ring and rotating ring, fit tightly between described stationary ring and the described rotating ring, it is matrix that described rotating ring adopts stainless steel, the manufacturing of surface spraying high-abrasive material forms, and described stationary ring adopts graphite or graphite+polytetrafluoroethylmaterial material manufacturing to form.By adopting mechanical end face seal that the water hinge is sealed, simultaneously rotating ring employing stainless steel is matrix, the surface spraying high-abrasive material, can utilize like this that the whole processability of stainless steel material is good, surface spray coating process is ripe, reduce production difficulty and production cost, stationary ring adopts graphite or graphite+polytetrafluoroethylmaterial material to make, then because the graphite wearing quality is good, lubricating ability is strong, the characteristics of good processability, make stationary ring easily reach the accuracy requirement of sealing surfaces, and processing cost is significantly smaller than pottery processing.
Further, described mechanical end face seal has quadruplet, and described water inlet pipe component and described return pipe assembly seal by the described mechanical end face seal of two covers respectively, described water inlet pipe component and described return pipe assembly all are supported and fixed on the described interior ring by rolling bearing, and described water inlet pipe component and described return pipe assembly are bolted as a whole.
Further, in a side of described stationary ring, the described water inlet pipe component spring is set, so that described stationary ring and described rotating ring are realized the auto-compensation of seal pressure and wearing and tearing.
Further, in a side of described stationary ring, the described return pipe assembly spring is set, so that described stationary ring and described rotating ring are realized the auto-compensation of seal pressure and wearing and tearing.
Preferably, at described rotating ring surface spraying high-abrasive material, described high-abrasive material is stupalith.
Be more preferably, described stupalith is silit or silicon nitride.
Further, surface of contact at described water inlet pipe component and described interior ring arranges the O RunddichtringO, the O RunddichtringO also is set on the surface of contact of described return pipe assembly and described interior ring, the setting that matches with described mechanical end face seal of described O RunddichtringO is to realize the auxiliary seal to the water hinge.
Preferably, described O RunddichtringO adopts polytetrafluoroethylmaterial material to make, and in described interior ring outer ring, with described O RunddichtringO contact position spraying chromium oxide so that the surface quality of described interior ring optimizes more, thereby reduce the wearing and tearing of O RunddichtringO.Because ring is generally aluminium material in the water hinge at present, be equivalent to a fixing axle, surface treatment is not now all carried out on its surface, the O RunddichtringO wearing and tearing of auxiliary seal are larger, and at the contact position spraying silicon nitride of interior ring and O RunddichtringO, not only can optimize the surface quality of interior ring, reduce the wearing and tearing of O RunddichtringO, can also increase the points hardness of interior ring, the serviceable life of ring in prolonging.
The beneficial effects of the utility model are: by with the water hinge by mechanical end face seal as the primary seal form, it is matrix that its rotating ring adopts stainless steel, the surface spraying high-abrasive material, can utilize so the whole processability of stainless steel material good, surface spray coating process is ripe, reduce production difficulty and production cost, high-abrasive material adopts stupalith simultaneously, can increase bulk strength and the wearing quality of rotating ring, effectively prolong the serviceable life of rotating ring, stationary ring adopts graphite or graphite+polytetrafluoroethylmaterial material to make, then can utilize the graphite wearing quality good, lubricating ability is strong, the advantage of good processability, reduce manufacture difficulty and processing cost, make the precision of sealing surfaces more easily reach requirement, whole water hinge is reduced working condition requirement, mission life increases; By spring is set, so that stationary ring and rotating ring are realized the auto-compensation of seal pressure and wearing and tearing, reduce the maintenance frequency of whole mechanical end face seal behind stationary ring; By the O RunddichtringO all is set on the surface of contact of water inlet pipe component, return pipe assembly and interior ring, the O RunddichtringO is as auxiliary sealing device, can not only prevent from revealing, can also cushion and compensate beating and process the error cause is installed by interior ring, contrast prior art, this water hinge have advantages of that sealing is reliable, the friction pair difficulty of processing is little, cost is low, have compensation rate between the friction pair, working condition requirement is low and long working life.
