Abstract
The invention relates to a leakage test device for an oil bottom shell. The leakage test device for the oil bottom shell is provided with a hand wheel, a compression plate, the oil bottom shell, sealing rubber, a working table, a bubble water tank, a gas tank, an air inlet pipe, a pressure testing rubber tube, an air inlet hole, a magnetic valve, a pressure regulating valve and a pressure gage, wherein the oil bottom shell is fixedly installed on the sealing rubber through the hand wheel and the compression plate, and the sealing rubber is fixed on the working table. The bubble water tank is arranged on the right side of the working table, and the air inlet hole is arranged in the middle of the working table. The pressure gage is arranged on the lower side of the working table, and the lower side of the air inlet hole is connected with the pressure testing rubber tube. The other end of the pressure testing rubber tube is connected with the magnetic valve, the magnetic valve is connected with the pressure regulating valve, and the pressure regulating valve is connected with the gas tank through the air inlet pipe. The leakage test device for the oil bottom shell has the advantages of being high in detection efficiency and obvious in leakage test effect and remarkably improving the product percent of pass and the like.
Description
Technical field
The present invention relates to a kind of device that weldment is carried out the leak test check, specifically a kind of oil sump leakage testing device.
Background technology
We know, when carrying out the leak test check in the welding position to oil sump, generally adopted the liquid leakage testing device in the past, this kind method only relies on the own wt of current to permeate to carry out leak test, often can not really test out the defective part of welding position in short time, lack the leak test link of pressure by this kind, substandard product often occurs in the product use procedure, diminish goodwill.
Summary of the invention
Technical matters to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and detects bleeder vent by applying certain pressure, and the leak test successful improves, oil sump leakage testing device that product percent of pass significantly improves.
the present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of oil sump leakage testing device, be provided with handwheel, pressure strip, oil sump, caulking gum, worktable, the foam tank, the copper packing case, the plug screw case, gas tank, draft tube, the pressure testing sebific duct, air admission hole, solenoid valve, pressure regulator valve, tensimeter, oil sump is fixedly mounted on caulking gum by handwheel and pressure strip, caulking gum is fixed on worktable, the worktable right side is provided with the foam tank, the worktable left side is provided with copper packing case and plug screw case, in copper packing case and plug screw case, copper packing and plug screw are housed respectively, the worktable middle part is provided with air admission hole, the worktable below is provided with tensimeter, connect the pressure testing sebific duct under air admission hole, the pressure testing sebific duct other end is connected with solenoid valve, solenoid valve is connected with pressure regulator valve, pressure regulator valve is connected with gas tank by draft tube.
The present invention is owing to adopting said structure, with handwheel, pressure plare, copper packing and plug screw, oil sump is fixedly mounted on caulking gum according to manometric force value, by controlling the pressure of pressure regulator valve, gas in gas tank is entered in oil sump by air admission hole, then by smear the foam water in the foam tank in the welding position, can be rapidly the leakage hole of position judgment oil sump welding position by Bubble formation, thereby whether the oil sump after the judgement welding is specification product.The present invention has that detection efficiency is high, leak test successful and the remarkable advantage such as improving product qualification rate.
Description of drawings
Fig. 1 is structural representation of the present invention.
Be labeled as in figure: 1. handwheel, 2. pressure strip, 3. caulking gum, 4. worktable, 5. foam tank, 6. copper packing case, 7. plug screw case, 8. gas tank, 9. draft tube, 10. pressure testing sebific duct, 11. air admission holes, 12. solenoid valves, 13. oil sumps, 14. pressure regulator valves, 15. tensimeters.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
as shown in Figure 1, the present invention relates to a kind of oil sump leakage testing device, be provided with handwheel 1, pressure strip 2, oil sump 13, caulking gum 3, worktable 4, foam tank 5, copper packing case 6, plug screw case 7, gas tank 8, draft tube 9, pressure testing sebific duct 10, air admission hole 11, solenoid valve 12, pressure regulator valve 14, tensimeter 15, oil sump 13 is fixedly mounted on caulking gum 3 by handwheel 1 and pressure strip 2, caulking gum 3 is fixed on worktable 4, worktable 4 right sides are provided with foam tank 5, worktable 4 left sides are provided with copper packing case 6 and plug screw case 7, interior copper packing and the plug screw of being equipped with respectively of copper packing case 6 and plug screw case 7, by copper packing and the plug screw degree of tightness to oil sump 13, make the tensimeter 15 of worktable 4 belows meet the requirements of force value, worktable 4 middle parts are provided with air admission hole 11, worktable 4 belows are provided with tensimeter 15, air admission hole connects pressure testing sebific duct 10 11 times, pressure testing sebific duct 10 other ends are connected with solenoid valve 12, solenoid valve 12 is connected with pressure regulator valve 14, pressure regulator valve 14 is connected with gas tank 8 by draft tube 9.
when the present invention uses, at first according to the manometric required value in worktable below, take out respectively copper packing and plug screw in copper packing case and plug screw case, fly and pressure strip are worth oil sump on request to be fixed and install, then regulate pressure regulator valve and reached needed atmospheric pressure value, then open solenoid valve, make gas finally reach air intake opening from gas tank by draft tube and pressure testing sebific duct, enter oil sump inside, effect due to caulking gum, make pressed gas all spray to the welding position of oil sump below oil sump, then dip foam water by hairbrush in the foam tank, spread upon the welding position of oil sump, when there is bleeder vent the welding position, will form foam, thereby judge rapidly the position of the bleeder vent of oil sump, then with the pen mark, rear ventilative position is repaired wait unloading.If there is no foam, prove that this product is specification product.
