Analysis of knowledge about hydraulic pipe fittings
Hydraulic fittings are connectors between the oil pipe and the oil pipe, oil pipe and hydraulic components, should meet the requirements of solid connection, reliable sealing, small overall size, small pressure drop, large flow, easy disassembly and assembly, and good process performance, especially the sealing performance of the fittings is an important factor that affects the leakage of the system. Therefore, sufficient attention should be paid to the pipe joints.
In the hydraulic system, the outer diameter of more than 50 mm metal pipe is generally connected with a flange. For small diameter oil pipe fittings, there are many kinds of commonly used pipe fittings, which can be categorized into straight-through, angular, three-way and four-way according to their number of channels and flow direction. According to the oil pipe, it can be divided into flare type, welding type, collar type and so on.
Corrugated metal hose Model: tcJR metal hose nominal diameter: DN8 ~ DN400 working pressure: 0.6 ~ 1.0 (MPa)
Stainless steel metal hose is made of stainless steel bellows outer braided one or more layers of steel wire or steel belt mesh sleeve, two ends with a connector or flange head, used to transport stainless steel metal hose a variety of media, flexible components. II. Features:Corrosion resistance, high temperature resistance, low temperature resistance (-196 ℃ ~ +420 ℃), light weight, small size, good flexibility. Widely used in aviation, aerospace, petroleum, chemical industry, metallurgy, electric power, papermaking, wood, textile, construction, medicine, food, tobacco, and other industries. 1. Conveying corrosive chemical medium or organic solvent. (For example: loading and unloading ammonia, acetone, etc.) 2. Conveying high temperature gas, hot oil and other high temperature media. (e.g. hot steam, thermal oil, etc.) 3. Conveying low-temperature or ultra-low-temperature media. (e.g. liquid nitrogen) 4. Conveying water, steam, oil and other media in high temperature environment. (eg: coking, steelmaking, continuous casting equipment in the water vapor system and hydraulic system) 5. Need to dampen or eliminate the noise of the pipeline. (For example: pump import and export)
