The brake system mostly uses metal pipes. Because metal has no elasticity, it will not expand at any time due to the increase in the pressure of the liquid, which can fully ensure the transmission of braking force. The main feature is: a "medium" that uses liquid (oil) pressure to transmit the braking energy of the hydraulic system, and plays the role of energy transmission, system lubrication, anti-corrosion, rust prevention, and cooling in the hydraulic system. Therefore, the requirements for this "high-pressure" pipeline for transferring energy are very strict, and it is not a common material that can be substituted. Nowadays, metal materials are mostly used, but there are more wire-like wraps when it comes to the brake disc (disc). The reason for the rubber tubing is determined by the steering changes of the tires and the flexibility of the components to follow.
More mechanical or electronic power-assisted systems are used. When the power-assisted pump is working (mechanical non-stop working, electronic working under the control of the control unit at the right time), it is driven by the kinetic energy of the engine (mechanical) or an independent drive motor Drive (electronic) to drive the oil pressure in the electronic hydraulic pump to output in a high-pressure state to make the hydraulic system piston move in a certain direction, thereby reducing the intensity of "manual" operation and achieving the purpose of "saving labor". For this kind of oil pipe, it is also a special oil pipe that requires multiple functions such as pressure resistance, temperature resistance, lubrication, anticorrosion, rust prevention, and cooling.
The "liquid" (freon) of the air-conditioning system flows and forms high-pressure gas after vaporization (atomization).
Different from household air conditioners, both cold and heat need to be obtained through compressor work. The car’s air conditioner design requires compressor work when cooling, and the hot air state can be provided by the engine part. When refrigerating, the high-temperature and high-pressure gas from the compressor is cooled by the unique structure inside the condenser to form a liquid state, and then flows through the throttle valve to reach the control pressure, adjust the pressure, and enter the evaporator.....It can be seen that The high-temperature and high-pressure gas (or liquid) flow direction needs to be "taken" by pipelines that can withstand high pressure. Therefore, the air-conditioning high-pressure pipe plays a very important role. It is common in metal materials and also has special colloidal pipes. The design of the car model.
