How to use the Hydraulic Hose?
the hydraulic hose in the system pipeline more widely used. However, in actual use due to improper use and maintenance, resulting in hydraulic hoses leak more failures. Therefore, the proper use and maintenance of hydraulic hoses in order to extend its life and improve the reliability of its use.
1.Hydraulic hose leakage analysis
(1) Leakage due to reduced hose life due to improper hose installation. Hydraulic hoses have a theoretical neutral angle (typically 54。4 J454), whether in woven or wound reinforcement. When the hose is installed, if the pipe is twisted or the bending radius is small, the neutral angle of the reinforcing layer will deviate from the theoretical neutral angle so that the carrying capacity of the hose drops obviously, leading to the early explosion of the hose and the oil leakage. The test results show that when the hose is twisted 5。, hose life will be reduced to 70% of the original life expectancy.
(2) The use of the hose ambient temperature exceeds the allowable range, leading to the hose material aging cracked and cracked oil leakage. Due to the material properties of the hose, there should be a suitable operating temperature range. If the oil temperature of the hydraulic system or the working environment of the hose is too high, it will cause the hose material to age and crack in advance.
(3) hose itself flawed, and external scratches or work with other parts of the frequent friction, will lead to the hose to shorten the service life, and crack oil spill in advance.
