Application of YATAI rubber hose in construction machinery

Apr. 09, 2020

The hydraulic system is an indispensable core system in the construction machinery industry, and the hydraulic hose is an indispensable accessory product of the hydraulic system. It is used to transport or suck various gaseous, liquid or solid materials under positive or negative pressure. It is more and and important, so it is called the "vessel" of industry.

In recent years, due to the compact design and compact installation of industrial equipment, hoses are required to have a smaller bending radius, and the changes in the use environment and the transmission medium will allow the hose to withstand higher or lower temperatures, better pulse performance, and better in terms of medium resistance performance, higher requirements have been put forward, and these requirements have driven us to continue to develop and improve.

一. The classification of hoses used in construction machinery industry

There are many types of hoses used in the construction machinery industry, mainly:

Steel wire braided hose, steel wire spiral hose, fiber braided hose, embedded steel wire suction hose, etc.

二. Standards and introduction of commonly used hoses in the construction machinery industry

1. Steel wire braided hose

⑤Common specifications: 3/4 ”-12” ,other size can be customized

三. Principles for selection of hydraulic hoses used in the construction machinery industry

  When selecting hoses and hose combinations, the following aspects should be noted:

1. Working environment: ambient temperature, climatic conditions, and external contact with other materials

2. Transmission medium: liquid, gas, solid, or a mixture of the above

3. Conveying method: pressurized discharge, vacuum suction

4. Working conditions: pressure and temperature of conveying medium, frequency of use, pulse or movement.

Assembly assembly: degree of bending; vibration of the system; risk of damage due to impact and friction; use of the correct connection type.
