To select the appropriate hydraulic hose testing equipment, you need to consider the following aspects:

1. Purpose of testing
① Pressure test: If the main purpose is to test the maximum pressure that the hydraulic hose can withstand, you can choose a hydraulic hose pressure test bench, such as the TWS8-ST-1200 pressure test bench of Beijing Haifuda Technology Co., Ltd., whose test pressure can reach 0~1200bar, and can accurately test whether the hose has leakage defects.
② Pulse fatigue test: For situations where the fatigue performance of hydraulic hoses under repeated pressure changes needs to be evaluated, the hydraulic hose pulse test bench is a suitable choice, such as the hydraulic hose assembly pulse test machine provided by Tianjin Getes Testing Equipment, with a maximum pulse pressure of 100MPa and a pulse frequency of 0.5~1.25Hz that can be set arbitrarily.
③ Burst test: If you want to determine the burst pressure of the hydraulic hose, you need to use a hydraulic hose burst test machine, such as the hydraulic hose burst test machine of Simingte (Jinan), with a test pressure of 0~200MPa, which can be used for pressure burst tests of hydraulic hoses, hydraulic valves, etc.
2. Applicable standards
For different industries and application scenarios, hydraulic hose testing must follow corresponding standards. For example, in the aviation field, it is necessary to follow standards such as HB6133-2018, and the corresponding testing equipment should be able to meet the requirements of the standard for test pressure, pulse frequency, temperature range and other parameters; hydraulic hose testing in the automotive industry often refers to standards such as GB/T5563, and the equipment should comply with the performance parameters and test methods specified in these standards.
3. Hose specifications
① Pipe diameter: The pipe diameter of the testing equipment must match the pipe diameter of the hydraulic hose being tested. For example, the hydraulic hose assembly comprehensive test bench of Jinan Seist Fluid System Equipment Co., Ltd. has a pipe diameter of 6~51mm, which is suitable for flexural pulse testing of steel wire reinforced rubber and plastic hoses with pipe diameters within this range.
② Length: Some testing equipment has certain requirements for the length of the sample. It is necessary to select the appropriate equipment according to the actual length of the hydraulic hose to be tested. For example, some test benches require the sample length range to be 200-1000mm.
4. Detection accuracy
① Pressure accuracy: High-precision pressure sensors and control components can more accurately measure and control the test pressure. Generally, the pressure display accuracy is required to reach 0.01MPa or higher. For example, the burst test accuracy of Hongzhong expansion hose burst detection test instrument can reach 0.01MPa.
② Measurement resolution: Higher measurement resolution helps to detect pressure changes more accurately. For example, the pressure value resolution of the TWS8-ST-1200 hydraulic hose pressure test bench is 1bar.
5. Test medium
Common test media include water, hydraulic oil, emulsion, etc. Appropriate test equipment should be selected according to the actual working medium and test requirements of the hydraulic hose. For example, the test medium of the hydraulic hose comprehensive test equipment of Simingte Technology can be clean water, hydraulic oil, emulsion, etc.
6. Equipment function
① Automation degree: Equipment with high automation degree can improve the detection efficiency and reduce human errors. For example, computer-controlled test equipment can realize automatic pressure increase, pressure maintenance, data collection and analysis, test report generation and other functions. For example, the pulse test machine corresponding to the HB6133-2018 standard can control the pressure increase rate by computer, display the pressure curve in real time, and print the test report.
② Multi-station detection: Multi-channel and multi-station detection equipment can detect multiple hydraulic hoses at the same time to improve work efficiency. For example, some hydraulic hose test benches have 2-8 The test pipeline can be tested simultaneously without affecting each other.
③Data recording and analysis: Equipment with data recording and analysis functions can easily view and process test data, providing a basis for evaluating the performance of hydraulic hoses. For example, the hose high-pressure pulse tester tested by Reiter is equipped with a data acquisition system that can record the data of each test and analyze and process it.
7. Equipment reliability and stability
The reliability and stability of the testing equipment directly affect the accuracy and repeatability of the test results. Brands and models with a good reputation and market verification should be selected. At the same time, the material, manufacturing process and quality assurance system of the equipment should be checked to ensure that the equipment can operate stably for a long time.
8. Budget and cost
The prices of hydraulic hose testing equipment of different brands, models and functions vary greatly, and it is necessary to choose the appropriate equipment according to your own budget. On the premise of meeting the testing requirements, comprehensively consider factors such as the purchase cost, use cost (such as energy consumption, maintenance cost, etc.) and service life of the equipment to achieve the best cost-effective choice.
