How are hydraulic hoses classified?

Jul 06, 2020

Hydraulic hoses are used in mining hydraulic supports, engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machines, agricultural machinery, various machine tools, and machinery and automated hydraulic systems in various industrial fields.

According to the manufacturing process, hydraulic hoses are mainly divided into steel wire braided hydraulic hoses and high-pressure steel wire wound hydraulic hoses.

High-pressure steel wire winding hydraulic hose:
The structure of the high-pressure steel wire winding hydraulic hose is mainly composed of an inner rubber layer, a middle rubber layer, four or more steel wire reinforcement layers and an outer rubber layer alternately wound.
The inner rubber layer has the function of subjecting the conveying medium to pressure and protecting the steel wire from corrosion. The outer rubber layer protects the steel wire from damage, and the steel wire layer is a reinforcing material for the skeleton material.

High-pressure steel wire winding hydraulic hose uses: high-pressure steel wire reinforced hydraulic hose is mainly used in mining hydraulic support and oil field development, suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various industries Various machine tools and mechanical and automatic hydraulic systems in the field can deliver aqueous liquids (such as emulsions) with a certain pressure (higher pressure) and temperature. The maximum working pressure can reach 70-120Mpa.
   

Types of high-pressure steel wire wound hydraulic hoses:

4SP-Four-layer steel wire wound medium pressure hose.

4SH-Four-layer steel wire wound high-pressure hose.

Type R12-high temperature medium pressure tubing with four layers of steel wire wound under severe conditions.

Type R13-Multi-layer steel wire wrapped around high temperature and high pressure tubing under harsh conditions.

Type R15-Multi-layer steel wire wound high temperature and high pressure tubing under severe conditions.
 

Steel wire braided hydraulic hose:

The high-pressure steel wire braided hose structure is mainly composed of a liquid-resistant synthetic rubber inner rubber layer, an intermediate rubber layer, I, II and III steel wire braided layers and a weather-resistant synthetic rubber outer rubber layer.

Steel wire braided hydraulic hose use: steel wire reinforced hydraulic hose is mainly used in mining hydraulic support and oil field development, suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and various Kinds of industries. The department's mechanized and automated hydraulic system can deliver petroleum-based (eg mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (eg emulsion, oil-water emulsion, water) and temperature under certain pressure. Liquid drive.
