What Should We Pay Attention to when Using Hydraulic Hoses?

Hydraulic Rubber Hose is a hose commonly used to transport liquid substances. It has good pressure resistance and resistance, and has a good pulse function. The hydraulic hose structure is mainly composed of a liquid-resistant synthetic rubber inner rubber layer, a middle rubber layer, a multi-layer reinforced layer, and a weather-resistant synthetic rubber outer rubber layer. The inner rubber layer has the effect of subjecting the transport medium to pressure and protects the steel wire or wire fiber from corrosion. The outer rubber layer protects the reinforcement layer from damage. The reinforcement layer is a skeleton material and the role is to ensure the use pressure of the hose.

Hydraulic hoses are mainly used for mine hydraulic supports, 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 industrial departments mechanized and automated hydraulic systems. Petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquid (such as emulsion, oil-water emulsion, water) and liquid transmission with certain pressure and temperature. The rubber hose of rubber and plastic materials is also called rubber and plastic hose. It is a new type of rubber hose, which has obvious corrosion resistance and energy saving effect.

In order to reduce the frequency of problems with hydraulic hoses during operation, pay more attention to them during operation.

In general, when performing twisting operations on hydraulic hoses, it should be noted that the twisting radius cannot exceed the regular twisting radius, otherwise the hose skeleton will be damaged, or it will show excessive spread, resulting in damage to the hose. When using hydraulic hoses, select the appropriate type of hydraulic hose according to the actual situation, and do not choose the wrong one. When using hydraulic hoses, pay attention to adjust the pressure of the hose slowly and evenly to prevent damage to the pipe body due to the sudden increase in pressure. It should be noted that after the hydraulic hose is used, it should be transferred off the ground during the transfer process, and do not drag the ground to avoid damage to the pipe body. After the corrosive liquid is transported by the hydraulic hose, the residue inside should be removed in time to prevent the residue from corroding the pipe body. As long as this is done when using hydraulic hoses, the operating time of hydraulic hoses can be extended to reduce the occurrence of failures.

If the hydraulic hose has quality assurance, if it is damaged, it should generally not be used. The first is the installation process. At the same time, the hydraulic hose should always be checked during normal use. Here, Industrial Hose Manufacturer records the points that need attention during normal operations:

1. Do not distort the high-pressure hose during the first installation, otherwise the hydraulic hose will be damaged or the joint will be loose.

2. Install high-pressure rubber hoses between objects, leaving a certain space to avoid conflicts between high-pressure rubber hoses and objects during operation. If not, try to get some protection. For example, the use of high-pressure hose sheath.

3. During normal operation, the pulling of the valve stem should not be too strong, but it needs to be gentle, otherwise the high-pressure hose will burst.

4. In order to avoid damage to the high-pressure hose and restricted flow rate, the tortuous radius should be increased as much as possible.

5. When the temperature rise of the hydraulic system is too high during operation, the high-pressure oil pipe should be checked in time, and the necessary cooling method should be adopted during successive operations.

6. When the bending radius of the hydraulic hose is too small, the right angle joint is generally used to avoid the sharp bending and distortion of the hose.

The above is the place to pay attention to the use of hydraulic hoses.
