With the development of industrialization, rubber hose structures play an important role in practical applications. But for those who are new to it, this concept is still very vague. The structure of high-pressure steel wire braided rubber hose is composed of a rubber layer and a steel wire layer. The steel wire layer plays a role in strengthening the skeleton, and the rubber layer is divided into inner and outer rubber layers. The inner rubber layer bears the pressure of the conveyed medium, and the outer rubber layer plays a protective role to prevent the steel wire layer from being corroded.

The correct selection of rubber hoses can ensure the safety and rationality of the entire system, and the following points should be noted:

1. Rubber hoses need to withstand medium pressure, and the number of steel wire layers needs to be selected according to the system pressure. The higher the pressure, the more steel wire layers are required. Each rubber hose has a working pressure, and the burst pressure is four times the working pressure. According to the actual system pressure, the working pressure of the selected hose can be greater than the actual working pressure.

2. Choose the inner diameter based on the flow rate. If the pipe diameter is too small, it will increase the flow velocity of the medium inside the pipe, causing the system to heat up, reduce efficiency, and generate excessive pressure drop, which will affect the performance of the entire system. If the pipe diameter is too large, it will increase the cost, so the inner diameter of the hose should be appropriate. When using clamps to fix or pass through steel plates or other gaskets, attention should also be paid to the outer diameter of the rubber hose.

3. When using high-pressure steel wire braided rubber hoses, the bending radius of the pipe body needs to be considered, and the clamping length of the joint needs to be deducted when calculating the bending radius. If the bending radius of the installed hose is too small, the load-bearing capacity will be reduced and the service life will also be affected.

4. Select the joint type according to the hydraulic layout, such as flange joint, internal thread joint or external thread joint, 90 ° and 45 ° joint angles and overall assembly angle.

High pressure steel wire braided rubber hoses can be used for conveying liquids in hydraulic systems, and corresponding selection standards can ensure the safety and rationality of the system.
