Description
Technical field
The utility model relates to air tightness test technical field, especially a kind of hydraulic type air-tightness tester.
Background technology
Hydraulic pressure air tightness test mainly inspection pressure container water pressure resistance test, and whether each point of attachment has leakage phenomenon, especially medium toxic degree be higher, highly harm or design do not allow the pressure vessel of micro-leakage, must hydraulic pressure air-tight test be carried out.This type of testing tool of current most domestic also rests on the semi-automatic pressure measurement stage, carry out manual-lock bleed pressure by the numerical value of artificial visually examine's pressure and reach pressure controlled object, whether range estimation has leakage to judge workpiece quality, manual entry data also provide the modes such as data statistical tables and reports, this operation controls and typing mode exists very large human factor, accurate controlled pressure cannot be accomplished, real-time recorded data, thus cause test data inaccurate, unreliable and the defect that just exists in production run of Timeliness coverage product and later stage defective products can not dispatch from the factory and make producer produce unnecessary loss.
Utility model content
The utility model is for the deficiencies in the prior art, and propose a kind of hydraulic type air-tightness tester, structure is ingenious, easy to use.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme: a kind of hydraulic type air-tightness tester, comprise hydraulic pump, fluid pressure detects valve, source of the gas filtration unit, pressure transducer, supercharge pump and pressure-display device, described hydraulic pressure delivery side of pump and described fluid pressure detect valve and are communicated with, and described fluid pressure detects the valve other end and is communicated with testing container; The described source of the gas filtration unit be connected with high-pressure air source exports and is connected with described pressure transducer, then is communicated with described supercharge pump, and described supercharging delivery side of pump and described fluid pressure detect the pipeline communication between valve and described testing container; Described fluid pressure detects valve and is all connected with described pressure-display device with described pressure transducer.
Further, the described fluid pressure pipeline detected between valve and described testing container is set in parallel two.
Further, described supercharging delivery side of pump and described fluid pressure detect a pipeline communication between valve and described testing container.
Further, the pipe downstream that described booster pump outlet is communicated with offers the emptying passage of bypass.
Further, described hydraulic pump is provided with the outlet with described emptying channel connection.
Compared with prior art, the utility model has the following advantages: adopt high-precision liquid pressure valve and gas pressure valve detection and control simultaneously, realize high-acruracy survey and real time data monitoring, decrease all drawbacks artificially participating in producing, ensure the safety of personnel, prevent the cheating of test data, help to improve the quality control of parts production runes, the greatly lower disqualification rate that dispatches from the factory of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Be described in detail the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of hydraulic type air-tightness tester as shown in Figure 1, comprise hydraulic pump 2, fluid pressure detects valve 3, source of the gas filtration unit 6, pressure transducer 7, supercharge pump 8 and pressure-display device 9, liquid enters hydraulic pump 2 through manual modulation valve 1, outlet and the described fluid pressure of hydraulic pump 2 detect valve 3 and are communicated with, the other end that described fluid pressure detects valve 3 and testing container are communicated with pipeline 5 through two pipelines 4 in parallel, the described source of the gas filtration unit 6 be connected with high-pressure air source exports and is connected with described pressure transducer 7, be communicated with described supercharge pump 8 again, the pipeline 4 that outlet and the described fluid pressure of described supercharge pump 8 detect between valve 3 and described testing container is communicated with, described fluid pressure detects valve 3 and is all connected with described pressure-display device 9 with described pressure transducer 6.
The downstream that described supercharge pump 8 exports the pipeline 4 be communicated with offers the emptying path 10 of bypass, and described hydraulic pump 8 is provided with the outlet be communicated with described emptying path 10.Gas channel also can add PID valve, electrically-controlled valve, be convenient to automatic control.
The utility model adopts bite type high pressure resistant stainless steel pipeline as the flow-through substrate of pressure source, has the features such as high pressure resistant, easy for installation, not corrosion of pipeline itself, long service life; Equipment realizes high-precision pressure control, high-acruracy survey, real-time data record, automatic printing testing journal sheet to realize the Automatic Control of test process by host computer pid algorithm (ratio (P), integration (I) and differential (D)), decrease all drawbacks artificially participating in producing, ensure the safety of personnel, prevent the cheating of test data.Help to improve the quality control of parts production runes, the greatly lower disqualification rate that dispatches from the factory of product.
Compared with current manual testing's mode, this product realizes the automation mechanized operation of equipment, high precision step control, realtime curve and the function such as storage, autoreport printing completely, avoids the severe compromise of manual operation simultaneously.
