What Should I Pay Attention To When Selecting Hydraulic Hoses?

Several points to pay attention to when selecting Hydraulic Rubber Hose:

1. Size: The size of the inside diameter of the hose refers to the inside diameter (not the outside diameter) of the hose.

2. Temperature: The temperature refers to the temperature of the medium and not the temperature of the working environment.

3. Application: It mainly refers to the actual working environment of the entire hydraulic system.

4. Media: The inner rubber layer, outer rubber layer and pipe joint must have good compatibility with the medium in contact. (Chemical compatibility with media)

5, pressure: mainly refers to the following types of pressure: working pressure, pulse pressure, peak pressure, test pressure, burst pressure.

6. Connection of two kinds of threads at the end of the joint: The end of the pipe is usually determined by the oil port end of the equipment to which it is connected. The origin of the equipment has a great influence on the type of pipe joint.

7. Delivery status: The delivery time of the hose generally does not exceed 2 years.

What hydraulic system is used when choosing a hydraulic hose, the most important thing is to see what the actual working conditions are, because under severe working conditions, the working state and time of the same type of hose are different. Different standards such as SAE Hydraulic Rubber Hose.

SAE Hydraulic Rubber Hose

Hydraulic system evaluation system: When evaluating whether a hydraulic system is working well or badly, the most important consideration is the various conditions of the hydraulic hose, because in the entire hydraulic system, the power transmission and lubrication guarantee are all It is a hose that relies on excellent performance. The normal work of the entire hydraulic system is achieved by the reliable and stable work of each hydraulic component of the entire system.

In the selection of hydraulic hoses, we often consider a very practical question, which is the quality of the hydraulic hoses I choose. How long can it be used? This problem is also related to the failure of hydraulic hoses. At present, on the hydraulic system, the failure of the hydraulic wetting pipe mainly has the following performances:

1. The outer layer is torn or damaged, and the reinforcement layer shows signs of friction or corrosion.

2. The hose breaks at the bend, and the hose usually remains elastic.

3. The inner rubber layer is severely damaged, swollen or layered, or even detached.

4. The outer layer of the hose is foaming, and the inner or outer rubber layer is foaming or softening.

5. Fine cracks appear in the inner rubber layer, but still remain elastic. However, no obvious cracks were seen in the joints.

6. Hose bursts, reducing life. Usually, bursting occurs suddenly, with no signs of wear on the steel wire and outer rubber layer.

8. The hose is broken at the joint of the jacket.

The above list is some of the common failures of hydraulic hoses in general hydraulic systems. In these failures, the use of hydraulic hoses has a direct impact. In most cases, hoses that have the above conditions must be used. It must be replaced, otherwise the safety and reliability of the entire hydraulic system will pose a serious threat.

Usually, after the above situation occurs, we will quickly find the fault is in the pipeline of the entire system, what kind of function this pipeline undertakes, after analyzing, we will think about the cause, and propose to solve the problem specific measures.

The above are the issues that we should pay attention to when selecting hydraulic hoses by Industrial Hose Manufacturer. Hope to help everyone.
