Embodiment Construction
[0012] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0013] Such as figure 1 The hydraulic oil pipe shown has a five-layer structure from the inside to the outside, including a smooth composite inner wall layer 1, a middle rubber layer 2, an elastic metal mesh layer 3, an outer rubber layer 4, and a reinforcement layer 5. The composite inner wall layer 1, middle rubber layer The rubber layer 2, the elastic metal mesh layer 3, the outer rubber layer 4 and the reinforcing layer 5 are tightly combined to form a hollow circular pipe body. The composite inner wall layer 1 is made of a mixture of at least two oil-resistant rubbers. The middle rubber layer 2 and The outer rubber layer 4 is made...

The invention relates to a hydraulic oil pipe, and has five layers from inside to outside and comprises a smooth composite inner wall layer, a middle adhesive layer, an elastic metal mesh layer, an outer adhesive layer and a reinforcement layer, wherein the composite inner wall layer, the middle adhesive layer, the elastic metal mesh layer, the outer adhesive layer and the reinforcement layer are tightly combined into a hollow circular pipe body; the composite inner wall layer is made from a mixture of at least two kinds of oil-proof rubber; the middle adhesive layer and the outer adhesive layer are made from a mixture of butyl rubber and halogenated butyl rubber. The hydraulic oil pipe is manufactured by compounding multiple materials, so that the sealing quality of the oil pipe on a rigid connecting piece is improved, and the sealing duration of the oil pipe on the rigid connecting piece is prolonged; hydraulic oil flows in the oil pipe at high speed, and the pipe body is high in pressure bearing capacity, and the hydraulic oil pipe is high in permeation resistance, suitable for long-term use and has low possibility of aging.
Description
technical field [0001] The invention relates to the technical field of hydraulic auxiliary components, in particular to a hydraulic oil pipe. Background technique [0002] The function of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components and hydraulic oil. Due to its stable performance, the hydraulic system is widely used. However, the existing hydraulic pipes have poor pressure bearing capacity, and the hydraulic oil flows slowly, so that the use effect cannot meet the requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydraulic oil pipe in order to overcome the defects existing in the existing hydraulic oil pipe. [0004] The technical solution adopted by the present invention to solve the technical problem is: a hydraulic oil pipe with a five-lay...
