Quick question and answer: differential pressure airtightness tester must use standard parts? Jingcheng Engineering in-depth analysis

This article discusses whether the differential pressure airtightness tester needs to be used with standard parts. Daily testing equipment can be calibrated to directly measure the product, but equipment calibration, comparison, quality certification and customer acceptance, the standard parts are essential to enhance the reliability of testing. Precision Engineering suggests that the daily testing of direct measurement of the workpiece, verification with standard parts comparison, certification audit to provide standard parts traceability data.

Airtightness, IP rating, ATM waterproofing...one article to understand the product sealing thing!

This article discusses the importance of airtightness testing, the definition and relationship between IP protection level and ATM waterproof rating, and the professional leakage testing solutions provided by Precision Engineering. Airtightness is the basis for products to realize waterproof and dustproof performance, while IP protection level and ATM waterproof level are important standards to measure sealing performance.

Sealability Testing: Concepts, Methods and Equipment Selection Guide

This article provides a comprehensive analysis of seal testing, covering related concepts, common methods and equipment selection. Sealability testing is crucial for many products to prevent gas or liquid leakage and to ensure normal operation and service life of the products. The paper introduces the concepts of sealing and leakage, describes the testing methods such as water immersion method and pressure decay method, and recommends equipment such as airtightness tester and true water tester.

Quick question and answer: What are the two types of equipment that are resistant to vandalism and whether or not the product leaks the working medium, respectively?

The article introduces two methods for testing the safety and reliability of industrial equipment: strength test and hermeticity test. The strength test uses a bursting tester to assess the equipment's resistance to damage and pressure-bearing performance; the hermeticity test uses a differential pressure hermeticity tester, which is highly accurate and fast, and can effectively assess the equipment's hermeticity performance. The article also mentions the customized solutions and successful cases of Precision Engineering's airtightness team, demonstrating its technical advantages and application achievements in the industry.

Popularization: product sealing leakage test rating standards and methods for details

This paper describes the rating criteria and methods for product leakage tests for sealing. Leakage is the migration process of gas molecules driven by differential pressure, and the leakage rate is the measurement index. Test rating needs to consider the leakage medium, leakage rate, test pressure and time and other factors. Commonly used methods include immersion method, pressure decay method, differential pressure comparison method and tracer gas method.
