What are the compatibility test and selection points of Hydraulic Hose in complex fluid media?

In many industrial fields, hydraulic systems play an extremely critical role, and Hydraulic Hose, as an important connecting component in hydraulic systems, its performance in complex fluid media is directly related to the operating reliability and safety of the entire system.
First of all, compatibility testing is the core link to evaluate whether Hydraulic Hose can adapt to specific complex fluid media. This test covers many aspects, among which chemical compatibility is particularly critical. Different fluid media have different chemical compositions. For example, in some industrial environments containing strong acids, strong alkalis or special solvents, the material of hydraulic hoses must be able to withstand the erosion of these chemicals, otherwise it will cause rapid aging, hardening, embrittlement or even rupture of the hoses, causing serious hydraulic leakage accidents. We simulated actual working conditions, immersed hydraulic hose samples in specific fluid media, observed and tested them under different temperature, pressure and time conditions, and recorded the changes in their physical and chemical properties to determine their chemical compatibility.
In addition, temperature compatibility cannot be ignored. Complex fluid media are often accompanied by temperature changes. High temperatures may soften the rubber material of the hose and reduce its strength, while low temperatures may cause it to become hard and brittle. Therefore, we need to test the performance of hydraulic hoses in extreme temperatures and environments with frequent temperature fluctuations to ensure that they can maintain good flexibility, sealing and strength within the operating temperature range.
When choosing a Hydraulic Hose, there are several key points that must be kept in mind. First, accurately match the material of the hose according to the type of fluid medium. For example, for petroleum-based hydraulic oil, nitrile rubber (NBR) hoses are usually selected; for biodegradable hydraulic oil, special environmentally friendly rubber materials may be required. Second, consider the working pressure requirements. The hydraulic system will generate different degrees of pressure during operation. The selected hydraulic hose must have sufficient pressure resistance and a certain safety margin to prevent the hose from bursting due to excessive pressure. Third, pay attention to the size specifications of the hose. The appropriate inner diameter and outer diameter can ensure the smooth flow of hydraulic oil and reduce pressure loss, and it must also perfectly match other pipes and joints in the system.
