Abstract
The utility model relates to a lifting water leakage checking machine, which carries out leakage checking through adopting air-compressed lifting water to flood work pieces. The utility model comprises a water tank, a flange disc, a water guide barrel, etc., wherein, the water tank is divided into an upper and a lower parts by a table plate; the lower water tank is sealed; the upper part of a tank body is provided with an air inlet and an air outlet respectively; the flange disc which is installed in the utility model is connected with an electromagnetic change-over valve; the water guide barrel is arranged in the lower water tank, and the top end of the water guide barrel passing through the table plate is communicated with the upper and the lower water tanks. The lifting water leakage checking machine has the advantages of simple structure, low cost, high checking efficiency, etc., and is an ideal checking machine for each production line.
Description
The utility model belongs to the technical field of measurement and test of machine or structure member fluid sealability, is specifically related to a kind of employing lifting water leak tester that the lifting water logging there is not workpiece to hunt leak of calming the anger.
At present, domestic and international leak detection to the motorcycle engine parts has two kinds of methods.A kind of is to utilize leak detector that its parts are compared the formula leak test, and its method is directly part or parts and standard component (leaking anything but) thereof to be inflated simultaneously.After gaseous tension reaches setting, by sensor to whether the leak gas judgement of the formula that compares of its workpiece.This method is because detection time is long, and instrument requires high, adds that domestic accuracy of instrument is low, high-precision instrument has only dependence on import, cost an arm and a leg, so most production units seldom adopts this method, more have no talent and adopt this method in especially online leak detection aspect.So people have adopted another kind of leak hunting method one water inspection again.The inspection of traditional water is that each hole with workpiece carries out shutoff, and charges into and calm the anger, then with its submerged, observe it and whether produce bubble and judge and leak or do not leak, and the position of leaking.This method is except the hole that needs workpiece carries out the mechanism of shutoff, also needs a cover workpiece and plugging mechanism are sent into mobile device in the water in the lump, so just makes that mechanism is huge, complex structure, and also efficient is not high yet.
The purpose of this utility model is at existing leakage detection apparatus complex structure, bulky, efficient is low etc. shortcoming, provide a kind of pressurized air that adopts to make liter waterborne flood the sealing position of workpiece, observation charges into whether the cavity volume of calming the anger leaks gas and the lifting ability of swimming leak tester of definite leakage position, simple in structure, detect rapidly.
The technical solution of the utility model is as follows:
Lifting water leak tester comprises water tank, and water tank is divided into two parts up and down by platen, lower header is airtight, and casing top respectively has inlet, outlet, mounting flange, ring flange connects solenoid directional control valve, is provided with the water guide tube in the lower header, and its top is passed platen and is communicated with upper water box.Tank top is also established crossbeam, establishes oil cylinder or cylinder on the crossbeam, and crossbeam is divided into pressing plate, is threaded between oil cylinder, cylinder and the pressing plate.Screen pack is established on water guide tube top, and in upper water box, water guide tube top upper position has installed water retaining cover.The platform place that connects of ring flange and lower header air inlet/outlet is provided with O-ring seal, and platen and upper and lower water tank joint all seal with O-ring seal.
The characteristics of this leak tester:
1. this lifting water leak tester is compared with the traditional used travel mechanism of leak detecting of sinking to, and structural refinement is simple, and corresponding manufacturing cost reduces.
2. the time of premium on currency time ratio travel mechanism travelling workpiece will lack, and can reduce the running time, improves detection speed.
3. this leak tester can be widely used in the parts of motorcycle engine, the leaking hunting of pipeline, oil pump nozzle and the valve member etc. of gas heater, water tank air conditioner, but also applicable to the multiple medium that leaks hunting, as water, wet goods.
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the utility model structural drawing.
Among the figure: 1. lower header 2. 3. platen 4. ring flanges 5. solenoid directional control valves 6. O-ring seals 7. upper water boxs 3. water guide tubes 9. water retaining covers 10. screen pack 11. crossbeams, 12. oil cylinders (cylinder) 13. pressing plates of medium (water or oil) that leak hunting
Embodiment: as shown in the figure, this lifting water leak tester comprises compressing on water tank and its, packoff, water tank is divided into upper water box 7 and lower header 1 by platen 3, lower header 1 is airtight, the interior medium (water or oil) 2 that leaks hunting of adorning, air intake opening and gas outlet are arranged respectively at lower header 1 top, and inlet, outlet is by screw mounting flange 4, and ring flange 4 connects solenoid directional control valve 5.Establish water guide tube 8 in the lower header 1, the upper and lower water tank 7,1 of platen 3 conductings is passed on water guide tube 8 tops, and screen pack 10 is established on water guide tube 8 tops, and water retaining cover 9 correspondences are located at top position, water guide tube 8 top.Platen 3 seals with O-ring seal 6 with upper and lower water tank 7,1 joint, and ring flange 4 is also used O-ring seal 6 sealings with inlet, outlet joint edge.Compressing on the water tank, packoff comprise the oil cylinder or cylinder 12 and the pressing plate 13 that are subjected to crossbeam 11 supportings that is fixed on the water tank, establish oil cylinder or cylinder 12 on the crossbeam 11, and crossbeam 11 is divided into pressing plate 13, between oil cylinder or cylinder 12 and the pressing plate 13 with being threaded.
The operating process of this leak tester is as follows:
To be put on the upper water box anchor clamps by test specimen, the piston rod of oil cylinder 12 is descending, and pressing plate 13 is pushed down by test specimen and each hole of shutoff, and right solenoid directional control valve 5 is opened, and pressurized air is entered on 2 in the medium of leaking hunting in the lower header 1 by the direction of arrow.Leak hunting 2 in medium of pressurized rises to upper water box 7 along water guide tube 8, and until flooding each sealing surface of test specimen, right solenoid valve 5 cuts out.In the premium on currency process, another gas circuit is inflated the test specimen cavity volume.After treating that pressure reaches setting, stop to inflate and detecting.After detect finishing, left solenoid valve 5 is opened, and the pressurized air on 2 in the medium of leaking hunting is discharged thus, and the medium 2 that leaks hunting descends along water guide tube 8 again, and when reducing to down water level, pressing plate 13 is unclamped in the dismounting shutoff, unloads test specimen, and a complete test loop process promptly finishes.
