Oil-resistant hoses are used in oilfield development, engineering construction, hoisting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and machinery and equipment in various industries, as well as pressure and temperature-based oil transportation in automatic hydraulic systems. (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricants) and water-based liquids (such as emulsions, oils, emulsions, water) and liquid pipelines.
What aspects should be considered in the selection process of oil-resistant hose?
Different types of oil-resistant hoses have different working pressures. When choosing a hose, first determine the working pressure of the system, and then select the working pressure of the corresponding hose. If the system is subject to frequent pressure shocks, increase the working pressure when selecting a hose with a higher pulse life. When choosing the inner diameter of the oil-resistant hose, it is especially important to consider the size of the inner diameter.
If the inner diameter is too small, it will increase the flow speed of the medium, make the system heat up, reduce the work efficiency, and affect the working performance of the system. If the inner diameter is too large, it will increase the cost. Therefore, the inner diameter of the appropriate size should be selected according to the flow of the medium. All oil resistant hoses have an allowable operating temperature range.
Appropriate operating temperature can ensure the life and pressure resistance of the hose. If the long-term working temperature of the equipment exceeds the allowable temperature range of the hose, it is necessary to buy a special hose, or an oil-resistant hose with a special protective cover. If the conveyed medium is special, it is also necessary to ensure that the material of the hose is compatible with the medium.
