Hose Assembly Selection

Hose assembly usage affect many factors, only in accordance with the conditions and the correct selection of hose fittings, hose used in order to ensure the reliability and economy. These factors are:
1, hose sizeHose diameter Hydraulic pipe fittings, too small diameter pipeline will increase the flow rate of the medium, the system heat, reduce efficiency, and will produce excessive pressure drop, affecting the overall system performance, if the hose with hose clamps fixed or wear over steel and other spacers, they should also pay attention to the outside diameter of the hose.
2, the working pressureGenerally 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.
3, the impact stress and fatigue lifeThe selection is based on the hydraulic hose system design maximum pressure value determined. As the hydraulic system pressure value is usually Hydraulic adapters  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.
