Hydraulic rubber hoses are classified in several ways: 1. by application; 2. by structure; 3. by core wire type; 4. by length; 5. by material. Generally, hydraulic rubber hoses are classified by diameter as follows: 0.5mm and 2.0mm. Different materials are selected according to the application, mainly for liquid transportation or hydraulic systems. Hydraulic rubber hoses are prone to fatigue damage due to vibration or bending during operation, therefore requiring good high-pressure resistance and tensile strength. High-strength special engineering plastics (such as polytetrafluoroethylene) are typically used. To avoid bending damage and leakage, the hose body is well-sealed and wound with high-strength steel wire.
Hydraulic rubber hoses are mainly divided into two types: wound steel wire and braided steel wire.
Wound steel wire hoses generally do not experience tangling during use. If winding steel wire is required, braided steel wire is generally used. If wound steel wire is used, special equipment and molds are required for forming. Therefore, the braiding and winding processes for hydraulic rubber hoses have different requirements for different applications. Braided rubber hoses and rubber cable hoses differ significantly in materials, which will be noticeable when purchasing. 1. One or more braided rubber hoses with a diameter of 20 mm to 80 mm are cut into round wires, wound with rubber rollers, and then vulcanized.
Features of rubber cable hoses: (1) Good corrosion resistance and long service life; (2) Suitable for transporting corrosive media; (3) Easy to install and can be used outdoors or indoors; (4) Inexpensive. Uses of rubber cable hoses: Hydraulic rubber hoses are mainly used for transporting hydraulic oil, water, and corrosive media. They can also be used for transporting low-pressure gases and liquids.
- Braided rubber hoses are generally multi-strand braided, with steel wire wound with rubber rollers.
Rubber cable hoses are generally formed in one piece, with the rubber layer and metal core wire wound into a cylindrical shape, and then another layer of rubber is wound. Its advantage is that it is not easily deformed during molding. Rubber cable hoses are made of various types of rubber braided together, with spiral steel wire and two layers of rubber forming three or four layers. Temperature range: -50~120℃; (1) The outer diameter of the rubber cable conduit is generally 10000mm, and the inner diameter is generally 40mm; (2). The outer and inner diameters of the rubber cable conduit are also different. Hoses can be used to lay large flow fluids; small diameter hoses are used to transport small fluids, and large diameter hoses are used to transport medium fluids. 3. Braided hoses do not tear; Rubber cable conduits use ordinary rubber materials as insulation layers, and high-density polyethylene (HDPE) as a new type of insulation structure, which combines the wires with the rubber cable conduit. When it is necessary to wrap steel wire, high-density polyethylene (HDPE) is usually used. High-density polyethylene (HDPE) has excellent high pressure resistance, and is also corrosion-resistant, oil-resistant, and aging-resistant. The strength and toughness of steel wire usually increase with the increase of density. When the cross-sectional area is larger than the diameter, it is easy to tear under external force; the steel wire cannot be completely flat and evenly distributed on the outer surface. Therefore, the uniformity of the steel wire cross-section is one of the important factors affecting the tensile strength of spring steel. 4. The tensile strength of braided rubber hoses is 1.5 times that of ordinary steel wire.
This is because rubber hoses are made from natural rubber, which has good elasticity, wear resistance, chemical resistance, heat resistance, and oxidation resistance. Rubber cable hoses are mainly used in machinery, electronics, electrical appliances, metallurgy, mining, chemical, and other industries. Rubber cable hoses are generally not wrapped with steel wire, but they usually require braiding. The design of rubber cable hoses varies depending on different product requirements: they are generally used for conveying aqueous solutions, diluting solutions, or diluting corrosive liquids. Different specifications are customized according to different applications and the needs of hydraulic rubber hoses.
