Users should use the hose in the hose quality specifications permitted temperature range. If the working ambient 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, recommended hose jacket. If you use special chemical compatibility of the hydraulic medium, Xingning City car with a hose price, the user should ensure that the choice of hose assembly in the hose, the outer layer, joints and O-rings which are compatible with the media. Bending radius bending radius meanings: as right, R is the hose can be bent without damage or shorten the life of the inner circle of the (minimum) radius. For a hose, automotive hose price, R value is certain. If the bend radius is less than when using the R value, the hose with textile reinforcement layer is kink may occur. Use a spiral wire hose will be better. Low temperature flexibility tests low rigidity: when the hose clamp with a diameter of 12 times the inner diameter of the hose twisting wheels, parked at a low temperature for 6 hours, the price of Leizhou car with a hose in the 12s 180 ° twist measured torque torque ratio measured at standard temperature. Cold bending: Hose clamp diameter of the hose inside diameter of 12 times round the twist, Gaoyao car with a hose price, parked at a low temperature for 24 hours, in the 10s twisting 180 °, check if the inner and outer rubber embrittlement and destruction . Measuring hose temperature brittleness easiest test is to sample 90 ° bend at low temperatures, or after a period of freezing compression hose 1/2 to see if embrittlement, free weights and a method of using a certain weight drop, impact test like to see if the sample embrittlement.
