Analysis of Durability Testing Process And Key Points for Rotary Joints

Durability testing is one of the key steps in evaluating the performance of rotary joints, mainly by simulating actual usage conditions to test the durability and stability of rotary joints.  The following are the general steps and methods for durability testing:

1、 Preparation stage

①　Determine testing objectives: Clarify the functional and performance requirements of the rotary joint in specific application scenarios, including working pressure, temperature range, speed, etc.

②　Develop a testing plan: Based on the testing objectives, develop a detailed testing plan, including testing equipment, testing methods, testing cycles, etc.

③　Prepare testing equipment: Prepare necessary testing equipment such as durability testing machines, pressure sensors, temperature sensors, speed sensors, etc.

2、 Testing phase

①　Installation and Debugging: Install the rotary joint onto the testing equipment and perform necessary debugging to ensure that the testing equipment can accurately measure the performance parameters of the rotary joint.

②　Apply pressure and speed: According to the test plan, apply the specified pressure and speed to the rotary joint to simulate actual usage conditions.

③　Monitoring and recording: During the testing process, real-time monitoring of the performance parameters of the rotary joint, such as leakage rate, pressure fluctuations, temperature, etc., and recording of relevant data.

④　Regular inspection: During the testing process, regularly inspect the rotating joint, including the wear of the sealing surface, the lubrication condition of the bearing, etc.

3、 Evaluation phase

①　Data analysis: Analyze the data recorded during the testing process to evaluate the durability and stability of the rotary joint.

②　Fault analysis: In case of leakage, fracture or other faults, fault analysis is required to identify the cause of the fault and propose improvement measures.

③　Evaluation report: Based on test data and fault analysis results, write a durability test evaluation report, summarize the performance of the rotary joint, and propose improvement suggestions.

4、 Precautions

①　Testing environment: The testing environment should be as close as possible to the actual usage environment of the rotary joint to ensure the accuracy of the test results.

②　Test cycle: The test cycle should be determined based on the expected service life of the rotary joint to ensure that the test can fully reflect the durability of the rotary joint.

③　Safety measures: Necessary safety measures should be taken during the testing process, such as setting up safety valves, pressure limiters, etc., to prevent safety accidents caused by excessive pressure or speed.

5、 Testing standards

Durability testing should follow relevant industry standards and specifications, such as JB/T and other standards related to rotary joints.  These standards specify the requirements for testing methods, testing conditions, testing cycles, and other aspects of rotary joints, which helps ensure the accuracy and comparability of test results.

In summary, durability testing is one of the important means to evaluate the performance of rotary joints.  Through scientific testing methods and strict testing standards, the durability and stability of rotary joints can be comprehensively evaluated, providing strong support for product design and improvement.
