Air-tightness detects technical current situation and detect efficiency improves a method

1Pa (detect precision and test condition are concerned) . High accuracy, efficient, low cost is the advantage of the biggest competition of this series product, in addition instrument interface is friendly, the operation is simple, and still deploy all sorts of communication interface, have powerful patulous function. The air-tightness that applies extensively at component of all sorts of a powerful person, pump, car, pipeline, engine, muffler to wait detects. Air-tightness detects the air-tightness that efficiency improves a method to be based on difference pressing to measure detects although the technology is mixed detect traditionally methodological photograph is compared, rose to detect efficiency and automation degree, but the requirement that still cannot satisfy manufacturing efficiency in some circumstances, accumulate when the content of the workpiece that be measured especially bigger when, detect certainly to assure precision, must assure to aerate enoughly time and balance time. Because, aerating in the process, aeriform temperature can produce change, if aerate,time and balance time inadequacy grow quite, temperature change cannot be stabilized come down, enter detect when the process, temperature change can cause the change that difference presses, make detect precision drops. Right now, detect precision and detect efficiency concerns with respect to what became contradiction. Detect to raise leak efficiency, a few more domestic and international the research organization offerred a few theory and means respectively, if aerate quickly method of compensation of law, temperature, add outfit filler to decrease to be measured the method such as the cubage inside workpiece. These detecting efficiency improved measure to get test and verify and development in applying actually. The air-tightness that like Beijing develop limited company of strange star automation is some gear-box to produce manufacturer to offer detects machine, after improving measure through using afore-mentioned efficiency, working metre rises 1 times by 2 original minutes every for every 1 minute 1, detect efficiency rose 50% . In addition, to satisfy the need that automation produces, this company developed the material on all sorts of collect again on the foundation of air-tightness detector, , detect, show, call the police, the function such as discharge the automation leak at an organic whole detects equipment. Graph 3 for Beijing limited company of Ta Jixing automation develops production and the device of automation leak hunting that already used product line of Yu Mou transmission at present. Graph 3 LTSA30 transmission / clutch housing air-tightness detects equipment afore-mentioned air-tightness detect although the technology can detect workpiece leak, but the specific position that cannot determine leak. In certain circumstance, detect when workpiece unqualified when, need puts work into cistern, the kind that carries water check decides leakage chooses the place. Detect to rise efficiency, new leak hunting machine often detects air-tightness (dry type leak hunting) as compound as water check function in an equipment. After the workpiece that be measured enters leak hunting plane, undertake doing type leak hunting above all, if workpiece is eligible, send work. Sink workpiece if workpiece is unqualified automatically in the cistern of lower part of leak hunting plane, undertake water check choose the place in order to decide leakage, the automation rate that raised air-tightness to detect further so and detect efficiency. In addition, college of Beijing grain industry detects technology and automation unit institute still began a research to work recently, use namely infra-red photograph what combine image to handle a technology to have leak place like appearance to detect, its fundamental is fill to the middle of workpiece than environmental temperature slightly low gas, use infra-red photograph film like appearance the temperature field image of the surface outside workpiece, if workpiece has leak, there is strange place in temperature field image, handle a technology through image this temperature curious aspect extraction comes out to be able to determine leak position. This method and the methodological posture that adopt water check to decide leakage chooses the place are compared, because do not need to undertake to workpiece follow-up dry cleanness is handled, can rise greatly detect efficiency. At present this research still is in lab phase, predict to be in not far can apply at production in the future actual. As the computer, electron, flying development that conducts feeling technology, leak detects technical development will welcome new development chance. Prospective air-tightness detects the technology develops the way that changes to high accuracy, efficient, intelligence further. Contemporary air-tightness detects the wide application of equipment also will pledge to assure a product quantity, safeguard produces the effect with raise business economic benefits to develop safe, mainer and mainer. Detect to raise leak efficiency, a few more domestic and international the research organization offerred a few theory and means respectively, if aerate quickly method of compensation of law, temperature, add outfit filler to decrease to be measured the method such as the cubage inside workpiece. These detecting efficiency improved measure to get test and verify and development in applying actually.
