Characteristics and classification of hydraulic hoses

        At present, the hydraulic hose joints on the market mainly include threaded connection, flange connection, quick connector connection and other types. Different types have different purposes. The main parts of the hydraulic hose are made of stainless steel, which ensures the good temperature resistance and corrosion resistance of the hydraulic hose. Moreover, there are many types of hydraulic hose joints, Specifications are mainly based on the size of the inner diameter to select the appropriate products. The breakage of hydraulic hose is usually not caused by very little apparent pressure, or it is related to the intensity of pressure influence and times. During the operation of construction machinery, the sudden increase or decrease of oil pressure will occur repeatedly in the oil pipe, which will form a severe pressure impact on the hydraulic hose, resulting in the damage and intensification of the oil seal of each part, the blistering and rupture of the rubber hose and the loosening and leakage of the pipe plug. Therefore, in manual operation, the pulling of the valve rod should not be so fierce, and it should be flat.
Hydraulic hose
        When installing the hydraulic hose, if the pressure is too large, or the plug and hose are too loose, the hose may come out of the joint at the end of use under the action of oil pressure; If the crimping amount is too small and the plug and rubber hose are pressed so tightly, it is not easy to cause local damage to the inner layer of the rubber hose, resulting in cracks. The high-pressure oil will indirectly transfer into the steel wire layer from the fracture, and then flow to the tail of the jacket along the gap between the steel wires, or always accumulate somewhere along the steel wire layer, causing bulge and fracture of the outer rubber. Characteristics and classification of hydraulic hose. The hydraulic hose is mainly made of stainless steel and has high corrosion resistance. The working temperature range of hydraulic hose is wide, ranging from - 196 to 600 ℃, with good high and low temperature resistance.
        The hydraulic hose body is hydraulically formed, with good flexibility, good flexibility, strong bending and seismic capacity, bending resistance, tensile resistance, lateral pressure resistance and so on. The hydraulic hose has good wear resistance, can prevent rat bite, and can protect the internal wires from damage. There are many types of high-pressure water cleaning joints. Appropriate joints should be selected, and the joint sleeve design should be standard and reasonable. Sharp grooves and irregular dimensions will break the steel wire reinforcement layer. When crimping the joint, the amount of crimping shall be determined according to the inner diameter and outer diameter of the hose. The hydraulic hose is equipped with many joints, which is easy to connect with other equipment. Both ends of the hose can also be made into other connection methods other than threads, also known as flanges, flanges or flanges, which is convenient to connect and use with other equipment. The hydraulic hose is easy to thread, install and locate, which is not only suitable for matching with the rotary joint, but also widely used in the soft connection of the transportation of a variety of fluid media (decisive substances).
Hydraulic hose
        What are the classifications of hydraulic hoses? Threading hydraulic hoses: threading hydraulic hoses are mainly made of stainless steel, with excellent flexibility, corrosion resistance and tensile resistance, high temperature resistance and wear resistance (a basic type of parts failure). They are mainly used as maintenance tubes for wires and cables. The hydraulic hose connector is made of high-quality carbon steel or stainless steel, and advanced crimping equipment and technology are adopted. Ultra high pressure hose is also widely used in our daily life. Corrugated hydraulic hose: corrugated hydraulic hose is mainly composed of corrugated pipe, mesh sleeve and joint. Corrugated pipe plays a flexible effect in corrugated hydraulic hose. It is made of thin-walled stainless steel with spiral or annular waveform. The mesh sleeve is woven by hydraulic wires or hydraulic belts interspersed with each other in a certain order. It is installed on the outer surface of the hydraulic bellows and has the effect of strengthening and shielding. The structural methods of joints are generally divided into three categories: screw type, flange type and quick type. For different application requirements, the connection methods between bellows, mesh sleeve and joint include welding type, mechanical clamping type and hybrid type. Plastic coated hydraulic hose: plastic coated hydraulic hose is a new type of hose. Its inner layer is specially treated with stainless steel hose or galvanized hose, and its outer layer is made of PVC material, which has the characteristics of anti ultraviolet and anti-aging.
