Problems solved by technology

(2) The operating temperature of the oil is too high
(3) The selection and installation of the rubber hose are unreasonable
[0007] At present, the problem of torsional cracking of hoses has not been well solved. The reason for this phenomenon is that the hoses are subjected to excessive torsion during installation or use. The existing high-pressure hoses have poor torsion resistance. , the inner layer of the high-pressure hose is frequently damaged due to excessive torsion, and once damaged, it needs to be replaced immediately

Abstract

The invention discloses an anti-twist high-pressure delivery pipeline applied to a hydraulic system, which belongs to the field of high-pressure delivery pipelines. The high-pressure hose body of rubber layer, reinforcement layer, middle rubber layer and outer rubber layer. The reinforcement layer includes ordinary spiral wrapping and bidirectional anti-twist spiral wrapping. A pair of two-way anti-twist units are arranged at the spiral gap of the belt. The two-way anti-twist units include a forward torsion extrusion unit and a reverse torsion extrusion unit. The forward torsion extrusion unit is located on the upper side of the reverse torsion extrusion unit. The reinforcement layer of the hose is set as two layers of spiral wrapping, and a two-way anti-twist unit is set on the spiral wrapping to make it have two-way anti-twist performance, which greatly improves the anti-twist performance of the high-pressure hose itself and reduces the stress of the high-pressure hose. Change frequency.

Description

technical field [0001] The invention relates to the field of high-pressure delivery pipelines, and more specifically relates to a twist-resistant high-pressure delivery pipeline applied to hydraulic systems. Background technique [0002] High-pressure rubber hose is used in mine hydraulic support, oil field development, engineering construction, lifting transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and various industrial sectors mechanized and automated hydraulic systems. Petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water) and pipelines for liquid transmission. [0003] The structure of the high-pressure steel wire wound rubber hose is mainly composed of an inner rubber layer, a middle rubber layer, four or more alternately wound steel wire reinforcement layers and an outer...
