The rubber hose used in construction machinery is a pipeline equipment used for conveying various media, with good pressure resistance, corrosion resistance, wear resistance, and other properties. It is widely used in various industrial fields, such as construction, mining, chemical and other industries. This article will introduce the specifications and types of rubber hoses used in construction machinery.

 

II Domestic standards

 

GB/T 3683-2001 "Rubber and plastic hoses and hose assemblies - Fabric reinforced for hydraulic purposes": This standard specifies the classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of fabric reinforced rubber and plastic hoses and hose assemblies.

 

GB/T 7939-2008 Terminology for Rubber and Plastic Hoses and hose assemblies: This standard specifies the relevant terms and definitions for rubber and plastic hoses and hose assemblies.

III. International standards

 

ISO 14362-1:2014 "Rubber and plastic hoses - Part 1: General requirements": This standard specifies the general requirements for rubber and plastic hoses, including materials, structure, dimensions, marking, testing methods, and other aspects.

 

ISO 14362-2:2014 "Rubber and plastic hoses - Part 2: Steel wire braided reinforced hoses": This standard specifies the requirements, test methods, inspection rules, and other aspects of steel wire braided reinforced hoses.

 

IV. Specification and type of rubber hoses on construction machinery

 

According to different usage requirements, rubber hoses used in construction machinery are usually divided into the following specifications and types:

 

Low pressure type: Low pressure rubber hoses are mainly used under low pressure conditions, and their working pressure is usually between 0MPa and 10MPa.

Medium pressure type: Medium pressure rubber hoses are mainly used under medium pressure conditions, and their working pressure is usually between 10MPa and 50MPa.

High pressure type: High pressure rubber hoses are mainly used under high pressure conditions, and their working pressure is usually above 50MPa.

 

V. Conclusion

The specifications and types of rubber hoses used in construction machinery are one of the important indicators to measure their performance. Consumers need to understand the relevant standard requirements and pay attention to checking whether they meet them when choosing. I hope this article can provide some reference value for the specifications and types of rubber hoses used in construction machinery.
