Hydraulic double ferrule tube fitting is an important connecting component in hydraulic systems, widely used in industrial equipment, engineering machinery, aerospace and other fields. Its core function is to ensure the high-pressure sealing and reliability of hydraulic pipelines, while also having the characteristics of easy installation and simple maintenance. With the continuous development of hydraulic technology, the design and performance of double ferrule tube fittings have also been continuously optimized, becoming an indispensable key component in modern hydraulic systems.
1, Basic structure of hydraulic double ferrule tube fitting
The hydraulic double ferrule tube fitting mainly consists of the following parts:
(1) fitting body : The main body of the fitting, usually made of materials such as stainless steel, carbon steel, or brass, with high strength and corrosion resistance.
(2) Front ferrule : located between the fitting body and the pipeline, its main function is to seal the connection between the pipeline and the fitting body.
(3) Rear ferrule: Used to fix pipelines and prevent them from loosening or falling off under high pressure.
(4) Nut : Tighten the ferrule and fitting body together through threaded connection to ensure stability and sealing of the connection.
2, Working principle of hydraulic double ferrule tube fitting
The working principle of hydraulic double ferrule tube fitting is based on the elastic deformation and mechanical fastening of the ferrule. When the nut is tightened, the front and rear ferrules undergo elastic deformation under pressure. The front ferrule tightly adheres to the outer wall of the pipeline to form a seal, while the rear ferrule is fixed by biting the outer wall of the pipeline. This design can not only withstand high pressure, but also effectively prevent the pipeline from loosening due to vibration or pressure fluctuations.
3, Advantages of hydraulic double ferrule tube fitting
(1)High sealing : The dual ferrule design can effectively prevent hydraulic oil leakage and is suitable for high-pressure, high-temperature, and corrosive environments.
(2)Easy Installation : No special tools are required, just tighten the nut to complete the installation, greatly improving work efficiency.
(3)High reliability: The interlocking design between the double ferrule and the pipeline can withstand large vibrations and impacts, ensuring long-term stability of the connection.
(4) Wide applicability : Can be used for pipelines made of various materials, such as stainless steel pipes, copper pipes, and carbon steel pipes.
4, Application fields of hydraulic double ferrule tube fitting
(1)Construction Machinery : In equipment such as excavators and bulldozers, hydraulic double ferrule tube fittings are used to connect components such as hydraulic cylinders, hydraulic pumps, and hydraulic valves.
(2)Aerospace : Double ferrule tube fittings are widely used in hydraulic systems of aircraft and spacecraft due to their high reliability and lightweight design.
(3) Industrial equipment: In machine tools, injection molding machines, and other equipment, double ferrule tube fittings are used to transmit high-pressure hydraulic oil to ensure the normal operation of the equipment.
(4) Energy industry : In fields such as oil, natural gas, and wind power, double ferrule tube fittings are used to connect high-pressure pipelines and withstand pressure and temperature in extreme environments.
