The high-pressure air tightness testing equipment utilizes a high-pressure air source as the primary power source to conduct high-pressure air tightness testing on the products being tested. The testing platform is controlled by a PLC and features a touch screen display in Chinese for operation. It employs pneumatic principles for rapid product clamping, utilizes wear-resistant silicone as the sealing component, and utilizes a high-precision pressure transmitter to detect pressure variations within the product and determine the product's air tightness based on the resulting pressure upper and lower limits. The clamping fixture, designed according to customer-provided product designs, achieves a versatility of over 90% for diversified products. The testing process is distributed, with products that pass (OK) automatically proceeding to the next step of testing, while products that fail (NG) are indicated by a corresponding light and an audible and visual alarm. The accessories used in the testing equipment are sourced from both imported and domestic renowned brands, ensuring stable and reliable operation
