SAE Hydraulic Hose Is Widely Used In Various Types Of Hydraulic Equipment


SAE hydraulic hose with good flexibility, pressure capacity, easy connection, etc., widely used in various types of hydraulic equipment, its reliability is directly related to the reliability of hydraulic equipment.

SAE hydraulic hose is usually composed of inner tube, reinforced layer, joint and so on. It is a flexible pipe element used to transmit hydraulic power. It has the advantages of good flexibility, strong pressure and easy connection. It is widely used in hydraulic equipment. SAE hydraulic hose Due to the impact of hydraulic shock, working environment temperature, oil pressure, load bending and torsion and other multi-field stress

SAE hydraulic hose selection method and routine maintenance points. Secondly, the reliability evaluation is based on the reliability data. According to the different reliability data of SAE hydraulic hoses, two kinds of reliability evaluation methods based on test data and field information are proposed. SAE hydraulic hose The former is the use of mathematical statistics method to deal with the test data to find out the form of failure distribution and then the reliability assessment; the latter is the use of fuzzy evaluation methods, different working conditions, different conditions of use under the conditions of SAE hydraulic hose reliability Fuzzy evaluation. Again, in order to obtain the test data for reliability assessment, SAE hydraulic hose according to the test technical requirements, the design of the reliability test bed. The pulsed test rig was designed by electro - hydraulic servo technology and virtual instrument technology. The pressure - resistant blasting test - bed was designed by gas - liquid element and virtual instrument technology such as gas - liquid pump. Finally, a batch of polytetrafluoroethylene hose assemblies were selected for the pulsed test and the pressure-resistant blasting test on the reliability test stand, respectively, SAE hydraulic hose and the reliability of the test data was evaluated by the proposed reliability evaluation method based on the experimental data , The results show that the batches of the hose assembly meet the design requirements, and verify the reliability of the proposed method of assessment of the feasibility.

SAE hydraulic hose is mainly used for mine hydraulic support, oil field mining, suitable for engineering construction, lifting transport, metallurgical forging, mining equipment, ships, SAE hydraulic hose injection molding machinery, agricultural machinery, various machine tools and industrial sectors mechanized, automated hydraulic system (Such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil and water emulsions, water) and the like, SAE hydraulic hose and liquid drives With the maximum resistance to working pressure up to 60MPa.
