How to reduce the error of Dalian leak testing machine and improve the stability of detection

In the production of industrial airtightness testing, the Dalian leak testing machine has large testing errors, data fluctuations, and poor repeatability, which are common problems that affect product yield and quality inspection credibility. Small detection deviations can easily cause problems such as misjudging and scrapping of good products, and the outflow of defective products. Therefore, by standardizing operations, optimizing equipment status, and stabilizing the detection environment, it is possible to effectively reduce errors in leak testing and greatly improve equipment detection stability and data accuracy.

Stable gas source pressure is the fundamental prerequisite for reducing detection errors. Pressure fluctuations are the primary cause of data drift in leak testing. During the production process, it is necessary to ensure stable air supply from the air compressor, promptly drain the accumulated water and oil inside the filter, and check whether the air pipe is bent, aged, or leaking. Regularly adjust and stabilize pressure to ensure consistent air pressure during each test and avoid data deviation caused by fluctuating air pressure.

Keep the tooling and equipment clean and prevent impurities from interfering with the detection. During the long-term mass production process, dust, oil stains, and debris are prone to accumulate in the gaps of the tooling, sensor surfaces, and sealing gaskets, leading to poor sealing and sensing failure. Clean the testing station before and after starting work every day, check whether the sealing rubber ring is worn, deformed, or cracked, replace aging parts in a timely manner, ensure that the sealing conditions for each test are consistent, and reduce system errors from the hardware level.

Standardized operating procedures and regular parameter calibration are important. Operators need to place the workpiece in a unified posture and fitting position to avoid detection differences caused by displacement. After each shift starts up, it is necessary to perform no-load calibration and retest of standard parts to correct equipment parameter deviation issues. At the same time, avoid long-term continuous overload operation of the equipment, perform scheduled shutdown self inspection, and ensure stable working status of precision components such as sensors and solenoid valves.

In summary, by stabilizing air pressure, cleaning fixtures, calibrating parameters, and operating according to regulations, the detection error of the Dalian leak testing machine can be effectively reduced, data repeatability can be improved, and the equipment can maintain a precise and stable detection state for a long time, providing reliable guarantee for quality control of the production line.
