The following methods can help pinpoint the root cause before requesting repairs or replacing equipment:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Diagnostic Procedure: Step 1\u2014Run the machine empty (without a packaging bag, with the lid closed). If the vacuum gauge reads \u2265 -90 kPa \u2192 The vacuum pump and chamber are functioning properly \u2192 Proceed to Step 2. If the vacuum gauge reads below -70 kPa \u2192 The equipment itself is malfunctioning \u2192 Proceed to Step 3.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Step 2\u2014Conduct the test using brand-new, undamaged packaging bags that have passed batch inspection. If the vacuum is maintained \u2192 The original packaging bags are defective (minor punctures, incorrect material selection, poor barrier properties). If the vacuum is still ineffective \u2192 Check the positioning of the packaging bags and their alignment with the sealing strip.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Step 3\u2014Equipment Troubleshooting:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1002\" height=\"447\" src=\"http:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-17.png\" alt=\"\" class=\"wp-image-5194\" style=\"aspect-ratio:2.2416541405949593;width:717px;height:auto\" srcset=\"https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-17.png 1002w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-17-300x134.png 300w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-17-768x343.png 768w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-17-18x8.png 18w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-17-600x268.png 600w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-17-150x67.png 150w\" sizes=\"auto, (max-width: 1002px) 100vw, 1002px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The primary cause that is most often overlooked: vacuum pump oil. Rotary vane vacuum pumps require an oil change every 500\u2013800 hours of operation (approximately once every 3 months under single-shift production conditions). Stale or contaminated oil can significantly reduce the ultimate vacuum and accelerate equipment wear. This is the most common cause of gradual performance decline, which operators often mistakenly attribute to \u201cmachine aging.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">YGPACK Service Advantages: All YGPACK equipment comes standard with an initial vacuum pump oil fill kit and a maintenance log card.
