Explanation of the design and use of a bearing airtightness tester

The bearing airtightness tester is designed to effectively solve the problem of bearing airtightness testing. With the development of industrial automation, the use of automated office equipment, automobiles, and household appliances is becoming increasingly widespread. Bearings are key components in the operation of automated equipment, and their compact design and sealing will directly affect the functionality and service life of the equipment. The emergence of bearings effectively solves the problems of low precision, poor anti-interference ability, and low efficiency in general airtightness detection.

Because the use of bearings has higher requirements for airtightness, the use of bearing airtightness testers and measurement data should also be more accurate. Bearing manufacturers must ensure the airtightness of bearings to meet the higher requirements of users working in underwater, high-pressure, and other environments. Because of this, bearing manufacturers also have higher requirements for the design of airtightness detectors. As a precision instrument and experimental measurement tool, the bearing airtightness instrument has very strict and standardized requirements for its operating environment temperature, humidity, shock resistance, fixture design, pipeline selection, and even connector selection.

The design principle of the bearing airtightness tester is the same as that of other airtightness measuring instruments. Compressed gases such as air, nitrogen, or helium are injected into the sealed container and workpiece, and then the leakage rate is measured by the pressure difference between the container or workpiece and the atmosphere. The use of the bearing airtightness tester is to measure the gas leakage rate value of the bearing within a unit of time, and determine whether the airtightness of the bearing meets the standard according to the set limit value. To ensure the accuracy of the measurement results, as with other measurement and testing equipment, before using the bearing airtightness instrument, the instrument should be tested first, and the performance of the leak detector needs to be calibrated so that the test results are accurate and effective.
