Abstract
The utility model discloses a device matched on a pull-press fatigue tester and used as a high inner pressure fatigue source. For provided with a water cooling system and an oil replenishment structure, the device enhances work efficiency under high-pressure, has convenience for oil replenishment and provides a good high pressure source for various experimental investigations of small-size high-pressure containers.
Description
The tired source apparatus of high interior pressure that the utility model relates to is applicable to the minitype high voltage container is done multiple experimental study.
On in July, 1975 " second international high pressure engineering meeting ", three people such as M.Nishihara have delivered " Fatigue Design of ultrahigh pressure vessel " literary composition, mention the torture test and the device thereof of high pressure vessel in the literary composition, and with the device synoptic diagram that constitutes by plunger, gland, sealing, high pressure cylinder, oil hole.But because of installing no cooling system, make its can only be under extremely low frequency (0.1～0.3Hz) work; The fluid supply also bothers; And test specimen can only be placed in the device and test, and trial stretch is restricted.
Task of the present utility model provides a kind of improved high pressure vessel fatigue experimental device.It can enlarge usable range; Increase work efficiency 10～50 times; And made things convenient for the supply of fluid.
Task of the present utility model is finished with following method: high pressure vessel is when carrying out Stromeyer test research, the friction because of sealing place often causes the overheated seal failure that makes, thereby having limited the frequency in the Stromeyer test can not improve, in order to improve test frequency, the utility model has been set up water-cooling system on plunger and high pressure cylinder, in order to coolant seal, further increasing work efficiency is test frequency.The water-cooling system of plunger according to the needs of processing technology, has selected for use water channel to add dividing plate, and in order to the controlled water flow route, lengthening water channel length improves cooling effect.Add that turnover water nozzle and sealing plug have constituted complete plunger water-cooling system.
In order to enlarge usable range, high-voltage power supply is drawn, set up the exhaust pressure transmission hole on the plunger, the exhaust pressure transmission hole is made up of upright opening and lateral aperture.It is that high pressure chest is with one of extraneous path.This exhaust pressure transmission hole can play degassing function to high pressure cylinder make-up oil liquid the time, when high pressure cylinder work, high-voltage oil liquid can be sent into tested container so that carry out the experimental studies such as fatigue strength, self-enhancement processing, explosion of container.
Water-cooling system on the high pressure cylinder is located at the sealing position, and water annulus is centered around the outside of sealing like square, adds that sealing plug and turnover water nozzle constitute complete high pressure cylinder water-cooling system.
The oiling plug is located on the oil hole of high pressure cylinder bottom, and the oiling plug links with screw thread with oil hole, itself is the bolt that one one end has spherical surface.Along a center oilhole is arranged on its center line, but do not pass sphere.The conical surface that is close to bulb has together that center line becomes 30 ° side oilhole, and two oilholes communicate, so can guarantee when the oiling plug unscrews, fluid can pass through the center oilhole, the side oilhole, walks around bulb, enters high pressure cylinder from oil hole.When the oiling plug screwed, bulb had sealed oil hole tightly, and the hydraulic oil in the high pressure cylinder can not be missed from here, had guaranteed the operate as normal of high pressure cylinder.
Characteristics of the present utility model are to have improved work efficiency, have enlarged trial stretch, have made things convenient for the supply of fluid.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the utility model.
Fig. 2 is Figure 1A-A cut-open view.
With reference to Fig. 1, plunger (1) is packed in the high pressure cylinder (8), and utilizes sealing (6) and gland (4) to guarantee that plunger is with the sealing between the high pressure cylinder.In order to cool off plunger (1), be drilled with two vertical water channels (5) (blind hole) and a horizontal water channel (5 ') (through hole) on the plunger (1) under high pressure with the heat that produces between the sealing (6).Vertical water channel (5) same level water channel (5 ') is intercommunication.Nozzle and spout (2) (2 ') is installed at horizontal water channel two ends respectively, insert dividing plate (3) in the two vertical water channels, shut the semicircle orifice of dividing plate both sides with sealing plug (16) at (notice that dividing plate is not inserted into the end, should reserve the necessary passage that chilled water passes through) top.Except that above-mentioned water-cooling channel, plunger (1) is gone up also has an exhaust pressure transmission hole (15,15 '), and the exhaust pressure transmission hole is made up of a upright opening (15) and lateral aperture (15 '), and this two hole is blind hole, and intercommunication.Guaranteed that high pressure chest (9) is with extraneous UNICOM.
See figures.1.and.2, pass to the heat of high pressure cylinder (8) for coolant seal (6), the through hole (also can be the blind hole of 4 UNICOMs) that has bored 4 mutual UNICOMs in the periphery of high pressure cylinder sealing place makes them constitute the belt water channel (17) of pros, and nozzle and spout (7) (7 ') is installed respectively on the diagonal angle.And seal all the other apertures with sealing plug (16 '), the water-cooling system of high pressure cylinder (8) can constitute.
On the oil hole (10) of high pressure cylinder (8) bottom, also be connected to an oiling plug (13), link with screw thread between them.The front end of oiling plug (13) is a sphere termination (14), and there is a blind hole at the center, and promptly center oilhole (12) leads to the sphere end, and communicates with side oilhole (11) that the sphere termination is faced mutually.Its tail end links with fuel feed pump.
When unscrewing oiling plug (13), can utilize and carry plunger (1) fluid is sucked from oil feeding reservoirs in the high pressure cylinder (8).Utilize exhaust pressure transmission hole (15,15 ') that the original gas in the high pressure cylinder (8) is discharged then, and make plunger (1) reach the requirement height.Screw oiling plug (13), block oil hole.This device is placed on the repeated tension and compression test machine, and with exhaust pressure transmission hole (15,15 ') with tested container UNICOM.The powerful fluctuation pressure that can utilize the fatigue test of materials machine to produce acts on the plunger, makes the liquid in the high pressure cylinder produce high pressure, thereby tested container is carried out the interior torture test of pressing.
This example is at 3Hz, 1500kgf/cm
2Press fatigue life test in down high pressure vessel being carried out.
