Abstract
Lip seal contact zone oil film property test equipment comprises oil chamber support seats which are used for fixing an oil chamber. First lip seals and second lip seals are respectively installed at two ends of the oil chamber. The lip seal contact zone oil film property test equipment further comprises an organic glass shaft sleeve which is connected on an output shaft of an alternating current dynamo in a sleeve mode. The organic glass shaft sleeve is tightly contacted with the first lip seals and the second lip seals. A hard rod lens fixed at the front end of a high-speed camera lens faces toward the first lip seals. The lip seal contact zone oil film property test equipment is adopted lowest cost to test property of the oil film contacted by a lip-shaped seal ring, width of the contact zone and service life of the seal ring. The lip seal contact zone oil film property test equipment can also be used on equal ratio performance test of other type seal rings.
Description
Technical field
The invention belongs to the 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 be brought into play, and is fine or not closely bound up with the design of hermetically-sealed construction, seal element sealing property.If seal failure, the loss that causes of the leakage of actuating medium or lubricating fluid is very surprising so, has both increased friction, wearing and tearing and the power consumption of machine, shortens the mission life of machine, also can cause because of leakage pollution, etching apparatus and the working environment of environment.More serious also can be therefore and the blast of catching fire causes security incident personal, equipment.So the research of carrying out Sealing Technology has been one of key research projects in the current techniques work.Lip-shaped sealed ring is simple in structure, compact because of it, and dependable performance can realize " zero leakage " on the definite meaning, and widely adaptability is arranged, and becomes the most frequently used and one of most important seal.
To the existing course in 50 years nearly of the theoretical research of lip envelope, from initial surface tension sealing theory reverse Pumping mechanism by now, what the researcher paid close attention to the most namely is that lip seals sealing and the lubrication mechanism that causes with the contact area oil film characteristic that is coupling both at home and abroad.Therefore, monitoring contact region oil film characteristic not only can the proof theory model to improve lip sealing property theoretical system, what is more important can provide theoretical foundation for estimating the O-ring seal life-span by the variation of contact oil film characteristic, and the evaluation in lip envelope life-span is the problem that the research of domestic outer lip envelope is still needed and solved.Therefore, the proving installation of lip sealing-in contact area oil film characteristic seemed particularly important.
At present, the monitoring of lip sealing-in contact area oil film characteristic is also lacked effective technological means, therefore the correctness for proof theory also has a lot of work not finish.Domestic patent of invention to the monitoring of lip sealing-in contact area oil film is few, the main means of testing that adopts is that the static and oil pocket of axle sleeve is by driven by motor in the world, the impact that centrifugal force brings but this method can't be got rid of is so the oil film characteristic of test is not the oil film characteristic under the 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 be under the 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 can utilizes current method 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 in order to the fixing oil pocket supporting seat 3 of oil pocket 5, wherein the first lip envelope the 4 and second lip envelope 6 is equipped with respectively at the two ends of oil pocket 5, also comprise the organic glass axle sleeve 7 that is socketed on alternating current generator 8 output shafts, organic glass axle sleeve 7 in the first lip envelope the 4 and second lip envelope 6 with the two close contact, be fixed in the stiff rod mirror 2 of high-speed camera 1 camera lens front end towards the first lip envelope 4.
Described alternating current generator 8 is connected to realize the electrodeless variable-speed of 0～6000rpm with frequency converter.
Described organic glass axle sleeve 7 is coaxial with oil pocket 5.
It is consistent that described the first lip envelope 4 and the second lip seal 6 structures, and internal diameter is all between 50～150mm.
Compared with prior art, the present invention has adopted the oil film characteristic of minimum cost monitoring lip-shaped sealed ring contact and the serviceable life of width of contact region and O-ring seal, can also be used for the geometric ratio performance test of other form O-ring seals.
Description of drawings
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 is bolted mounted motor base plate 9 at T-shaped groove platform 10, and alternating current generator 8 is fixed on the electric baseboard 9.Organic glass axle sleeve 7 is socketed on the motor shaft of alternating current generator 8, and fixes by round nut.Oil pocket supporting seat 3 is bolted on the platform 10, utilizes testing tool to guarantee the axis coaxle of alternating current generator 8 axis and oil pocket supporting seat 3 center pits before the bolted.Oil pocket 5 is bolted on the supporting seat 3, the first lip envelope the 4 and second lip envelope 6 is equipped with respectively at the two ends of oil pocket 5, organic glass axle sleeve 7 in the first lip envelope the 4 and second lip envelope 6 with the two close contact, be fixed in the stiff rod mirror 2 of high-speed camera 1 camera lens front end towards the first lip envelope 4, by adjusting camera height, determine that suitable position tests.
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, the recycle oil when being used to provide experiment.
Principle of work of the present invention is:
During work, alternating current generator 8 is connected with frequency converter, changes the electrodeless variable-speed that frequency realizes alternating current generator 0～6000rpm by frequency converter; Adjust stiff rod mirror 2 and high-speed camera 1, determine suitable position, utilize the good light transmission of organic glass axle sleeve 7, can test the contact region oil film characteristic and process by simple data to obtain width of contact region; Owing to using identical O-ring seal, therefore utilize current method can determine the output power of motor, process the friction torque that can obtain single O-ring seal by simple data.
Utilize 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, can obtain estimating the O-ring seal oil film characteristic theoretical curve in serviceable life by setting up the oil film characteristic variation tendency.
In sum, utilize the present invention successfully to realize the monitoring of contact region oil film characteristic under the O-ring seal duty; Realize 0～6000rpm stepless time adjustment, obtained the oil film characteristic under the different rotating speeds and width of contact region changes and the variation of friction torque; By changing the size of organic glass axle sleeve 7 and oil pocket 5, can adapt to the test of the lip-shaped sealed ring of different inner diameters.
