    basic introduction

    The hose (hose) assembly is an auxiliary device commonly used in hydraulic systems. It is made of high-pressure steel wire braided or wound hose and steel fittings withheld by special equipment. It is used to connect various hydraulic components in the hydraulic system. It is mainly used for hydraulic power under the working temperature of -40℃ to +100℃ Transmit or transport water, gas, oil and other high-pressure media to ensure the circulation of liquid and transfer liquid energy.

    Hose is widely used in automotive, aerospace, petroleum, chemical, marine, engineering machinery and other fields. In the automobile, it is mainly used for the major assemblies of brake, transmission, engine, air conditioning system, heat dissipation system, etc.; it is related to the braking safety and performance of the car. Considering the importance of the hose assembly in the system, there are many standards and specifications for hose testing at home and abroad. Each new model development and improvement will complete various hose tests in accordance with the corresponding test specifications of the OEM.
