简体中文Analysis of the application of special high heat-resistant materials for hydraulic solenoid valve coils
The heat resistance of the coil material selection of hydraulic solenoid valve coils, special heat-resistant materials play an important role in ensuring the stable operation of hydraulic solenoid valves under high temperature, high pressure and harsh working environment. The following is a more detailed introduction to special heat-resistant materials:
High-temperature alloys:
High-temperature alloys are a type of metal material that can work for a long time under high temperature above 600℃ and certain stress, and has good organizational stability. High-temperature alloys usually have a high melting point, good thermal strength, good oxidation resistance and thermal corrosion resistance, as well as good thermal fatigue performance and fracture toughness. In hydraulic solenoid valve coils, high-temperature alloys can effectively resist the thermal expansion, thermal stress and oxidation corrosion of the coil in a high temperature environment, ensuring the long-term stable operation of the coil.
Ceramic materials:
Ceramic materials are various products made of materials made of natural clay and various natural minerals as the main raw materials through crushing, mixing, molding and calcining. Ceramic materials have extremely high high temperature resistance, and some ceramic materials can even remain stable at high temperatures above 1000℃. In addition, ceramic materials also have good insulation, corrosion resistance and mechanical strength. In hydraulic solenoid valve coils, ceramic materials can be used to make coil skeletons or insulation layers to improve the heat resistance and insulation performance of the coils.
Graphite and composite materials:
Graphite is an allotrope of the non-metallic element carbon, which has good electrical conductivity and high temperature resistance. Graphite composite materials are new materials that combine graphite with other materials (such as resins, metals, etc.). Graphite and its composite materials not only inherit the high electrical conductivity and high temperature resistance of graphite, but also improve the mechanical strength and corrosion resistance of the material through compounding. In hydraulic solenoid valve coils, graphite and its composite materials can be used to make conductive elements or high temperature resistant insulation layers to improve the heat resistance and electrical conductivity of the coils.
