Description
Technical field
The invention belongs to sealing detection technical field, be specifically related to a kind of lip sealing-in contact area oil film characteristic proving installation.
Background technology
Can plant equipment run well, and performance could well play, and is closely bound up with the quality of the design of hermetically-sealed construction, seal element sealing property.If seal failure, the loss that so leakage of actuating medium or lubricating fluid causes is very surprising, has both increased the friction of machine, wearing and tearing and power consumption, shortens the mission life of machine, also pollution, etching apparatus and the working environment of environment can be caused because of leakage.More serious also can therefore blast of catching fire, cause the security incident of the person, equipment.So carrying out the research of Sealing Technology has been one of key research projects in current techniques work.Lip-shaped sealed ring because of its structure simple, compact, dependable performance, can realize " zero leakage " on definite meaning, and have adaptability widely, and become one of the most frequently used and most important seal.
Both at home and abroad the research that lip envelope is theoretical is had to the course of 50 years nearly, from initial surface tension sealing theory reverse Pumping mechanism by now, the sealing that lip envelope that namely what researcher paid close attention to the most be and the contact area oil film characteristic that is coupling cause and lubrication mechanism.Therefore, monitoring contact region oil film characteristic not only can proof theory model to improve lip sealing property theoretical system, what is more important can provide theoretical foundation for evaluating the O-ring seal life-span by the change contacting oil film characteristic, and the evaluation that lip seals the life-span is that domestic outer lip envelope studies the problem of still needing and solving.Therefore, the proving installation of lip sealing-in contact area oil film characteristic is seemed particularly important.
At present, also lack effective technological means to the monitoring of lip sealing-in contact area oil film characteristic, the correctness therefore for proof theory also has a lot of work not complete.The domestic patent of invention to the monitoring of lip sealing-in contact area oil film is few, the main means of testing adopted is that the static and oil pocket of axle sleeve is by driven by motor in the world, but this method cannot get rid of the impact because centrifugal force brings, so the oil film characteristic of test is not the oil film characteristic under real working condition.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of lip sealing-in contact area oil film characteristic proving installation, can under simulation actual condition, monitoring lip sealing-in contact area oil film characteristic and width of contact region; This device utilizes two identical O-ring seals, is convenient to dismounting and current method can be utilized to obtain suffered friction torque.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of lip sealing-in contact area oil film characteristic proving installation, comprise the oil pocket supporting seat 3 in order to fixing oil pocket 5, wherein the two ends of oil pocket 5 are equipped with the first lip envelope 4 and the second lip envelope 6 respectively, also comprise the organic glass axle sleeve 7 be socketed on alternating current generator 8 output shaft, organic glass axle sleeve 7 in the first lip envelope 4 and the second lip envelope 6 with the two close contact, the stiff rod mirror 2 being fixed on high-speed camera 1 camera lens front end is towards the first lip envelope 4.
Described alternating current generator 8 is connected with frequency converter the electrodeless variable-speed realizing 0 ~ 6000rpm.
Described organic glass axle sleeve 7 is coaxial with oil pocket 5.
It is consistent that described first lip envelope 4 and the second lip seal 6 structures, and internal diameter is all between 50 ~ 150mm.
Compared with prior art, present invention employs the minimum oil film characteristic of cost monitoring lip-shaped sealed ring contact and the serviceable life of width of contact region and O-ring seal, the geometric ratio performance test of other form O-ring seals can also be used for.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is oil recess structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
As shown in Figure 1, a kind of lip sealing-in of the present invention contact area oil film characteristic proving installation, T-slot platform 10 is bolted mounted motor base plate 9, and alternating current generator 8 is fixed on electric baseboard 9.Organic glass axle sleeve 7 is socketed on the motor shaft of alternating current generator 8, and is fixed by round nut.Oil pocket supporting seat 3 is bolted on platform 10, utilizes testing tool to ensure the axis coaxle of alternating current generator 8 axis and oil pocket supporting seat 3 center pit before bolted.Oil pocket 5 is bolted on supporting seat 3, the two ends of oil pocket 5 are equipped with the first lip envelope 4 and the second lip envelope 6 respectively, organic glass axle sleeve 7 first lip envelope 4 and second lip envelope 6 in the two close contact, be fixed on the stiff rod mirror 2 of high-speed camera 1 camera lens front end towards the first lip envelope 4, by adjustment camera height, determine that suitable position is tested.
Figure 2 shows that the structure of oil pocket 5, the oil-in 11 on it and oil-out 12 are connected with the import and export of oil feed pump respectively, are used to provide recycle oil during experiment.
Principle of work of the present invention is:
During work, alternating current generator 8 is connected with frequency converter, changes by frequency converter the electrodeless variable-speed that frequency realizes alternating current generator 0 ~ 6000rpm; Adjustment stiff rod mirror 2 and high-speed camera 1, determine suitable position, utilize the light transmission that organic glass axle sleeve 7 is good, can test contact region oil film characteristic and can obtain width of contact region by simple data processing; Owing to using identical O-ring seal, therefore utilize current method can determine the output power of motor, the friction torque of single O-ring seal can be obtained by simple data processing.
Utilizing this device by monitoring different time contact region oil film characteristic and width of contact region, revealed until O-ring seal loses efficacy to produce, the oil film characteristic theoretical curve in O-ring seal serviceable life can be obtained evaluating by setting up oil film characteristic variation tendency.
In sum, the present invention is utilized successfully to achieve the monitoring of contact region oil film characteristic under O-ring seal duty; Achieve 0 ~ 6000rpm stepless time adjustment, obtain the change of oil film characteristic under different rotating speeds and width of contact region change and friction torque; By changing the size of organic glass axle sleeve 7 and oil pocket 5, the test of the lip-shaped sealed ring of different inner diameters can be adapted to.
