the factors that affect the high-pressure hose assembly

Affect the use of high-pressure hose assembly of many factors, following a brief introduction for everyone:

1, hose size
Hose diameter should be appropriate, too small diameter pipeline will increase the flow rate of the medium, the system heat, reduce efficiency, and will produce excessive pressure on the overall system performance, if the hose with hose clamps fixed or through spacer plates, etc., we should also pay attention to the outside diameter of the hose.

2, the temperature range
Users should be allowed in the hose quality specifications used within a temperature range of hose. If the working environment temperature exceeds this range, it will affect the life of the hose, which will greatly reduce the ability to withstand pressure. Operating ambient temperature is too high or too low, long-term system, we recommend using the hose jacket.

3, the chemical compatibility
If you use special hydraulic banjo fitting medium, users should ensure that their choice of hose assembly hose inner and outer, joints and O-ring compatible with the media.

4, working pressure
Generally refers to dynamic pressure hose hose in continuous maximum allowable working pressure. In accordance with the provisions of the relevant international standards for hydraulic hose safety factor is generally recommended working pressure of the hose is usually a quarter of the minimum burst pressure values.

5, the impact stress and fatigue life
The selection is based on the hydraulic hose system design maximum pressure value determined. As the hydraulic system pressure value is usually dynamic and sometimes impact pressure, impact pressure peak is much higher than the maximum system pressure. However, the system generally have a relief valve, the impact pressure of the hose will not seriously affect the fatigue life. For particularly frequent shock pressure of the hydraulic system, suggested the use of particularly resistant to impact pulsation hose products.

6, the friction
Hose when used usual contact or friction with hard objects, the proposed increase in the external hose spring jacket.
