performance and the use of stainless steel hydraulic hose fittings

High pressure hose from the inner liquid-resistant synthetic rubber, rubber layer I to VI, wire mesh reinforcement and excellent weather resistant synthetic rubber cover. Especially suitable for mine hydraulic support, oil, suitable for construction, lifting and transport, metallurgy, forging, mining machinery, ships, injection molding machinery, agricultural machinery, machine tools and various industrial sectors mechanization and automation in the hydraulic system conveying certain pressure and oil-based (e.g., mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) the temperature of the liquid, water-based liquids (such as emulsion, oil - water emulsion, water), gas and liquid transfer information.
How to choose
Many factors can affect the use of the hose, choose a suitable hose and fittings according to the conditions of use, to ensure the reliability and efficiency of the hose. These factors are:
Shown in Figure 1, the tube size
The diameter of the hose diameter is too small, the flow velocity of the medium in the pipeline will increase, therefore, the system reduces the heat generating efficiency and excessive pressure drop, respecting the overall performance of the system, the hose clamp or hose wearing steel separator and the outer diameter of the tube.
2, working pressure
Dynamic pressure hose hose continuous operation, the maximum allowable pressure. General recommendations in accordance with international standards relating to the safe working pressure of the hydraulic hose is usually a quarter of the hose minimum burst value.
, Stress and fatigue
Pipe, the pressure in the hydraulic system to determine the maximum selected on the basis of design. Usually, the back-pressure value of the pressure in a hydraulic system, sometimes the effect of the pressure peak is considerably higher than the system maximum pressure value. However, the system has a pressure relief valve to control the back pressure does not greatly affect the life of the hose. The most frequent pressure in the hydraulic system, it is recommended to choose a special pulsating impact of hose products.
In the temperature range shown in Figure 4
The user should be able to use a temperature within the range of the quality hose hose. If the ambient temperature is higher than this range, it will affect the service life of the hose under pressure, can be greatly reduced. Long-term ambient temperature is too high or too low, the system, it is recommended that the hose jacket.hydraulic adaptors
Shown in Figure 5, the chemical compatibility
If you have a special hydraulic medium, the user should ensure that the hoses, outside, pipe fittings and O-rings and medium-compatible choice.
As shown in Figure 6, the bending radius
Meaning: right, R is the radius of the hose can be bent, but it does not damage or shorten the life of the inner circle (minimum).
A tube R-value. If the bend radius is less than the fabric reinforcement layer hose R value, you may bend. Spiral wire hose use would be better.
Shown in Figure 7, the friction
Normal use, the pants with hard objects contact or friction, it is recommended that the outer tube and the spring housing.hose adapters
