High-pressure oil pipes require a certain oil pressure and a certain fatigue strength. Taking the practical application as an example, the high-pressure oil pipe needs to meet the power of the diesel engine and the direct-injection gasoline engine of the high-pressure injection of the high-pressure oil pipe of the vehicle, and can accept the oil pressure required in the working process of the engine. Therefore, in the material selection and structural planning of high-pressure oil pipes, the influencing factors faced by these practical applications cannot be ignored.
The current high-pressure oil pipe is generally composed of a steel wire wound skeleton layer and a surface oil-resistant and corrosion-resistant synthetic rubber to form a high pressure. The planning of the steel wire wound rubber pipe has the advantage of being simple in planning. Compared with the viewpoint allocation planning method, only the planning program and parameter selection and calculation Different, the manufacturing process of the high-pressure oil pipe is exactly the same, and the axial deformation of the product is relatively small.
The non-uniform stress of the high-pressure tubing steel wire is an important part of summarizing the modification coefficient, and the non-uniform stress includes process elements and structural elements. The high-pressure oil pipe is planned by the structure and other stroke planning methods. The calculation of the burst pressure of the steel wire wound hose can be adjusted by the change value of the material strength utilization rate to adjust the summary modification coefficient, thereby reducing the influence of structural factors. Stroke planning methods such as the structure of the high-pressure oil pipe wire wound rubber hose can be used as visual distribution, and the tolerance planning of the construction stroke in the neutral angle planning can provide a reliable basis.
Hydraulic hoses are generally divided into steel wire woven hydraulic hoses and steel wire wound hydraulic hoses. Due to the variety of hydraulic hoses, it also determines the correct use and maintenance. Therefore, even if the quality of the hydraulic hose is extremely high, if it is not properly used and maintained, the quality and life of the hydraulic hose will be seriously affected, and major accidents that should not happen will damage the assets. structure and use.
hydraulic hose.
1. Hydraulic hose structure: It is mainly composed of a liquid-resistant synthetic rubber inner rubber layer, a middle rubber layer, a multi-layer reinforcement layer and a weather-resistant synthetic rubber outer rubber layer. The inner rubber layer has the effect of making the conveying medium bear the pressure and keeping the steel wire or wire fiber from corroding, and the outer rubber layer keeps the reinforcement layer from damage, and the reinforcement layer is the skeleton data.
2. Use of hydraulic hose: Mainly used for mine hydraulic support, oil field development, suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection machinery, agricultural machinery, various machine tools and the mechanization of various industrial sectors , Petroleum-based (mineral oil, soluble oil, hydraulic oil, fuel, lubricating oil) and water-based liquid (emulsion, oil-water emulsion, water) and liquid transmission with certain pressure and temperature in the automatic hydraulic system. Its corrosion resistance and energy saving effect are remarkable.
