In the installation and use of the hydraulic hose, there are also several issues that need to be paid attention to. The hose is too long, which affects the appearance and increases costs. The hose is too short. When it is stretched or contracted under pressure, there is not enough room for expansion and contraction, which will cause the hose to be damaged. When installing the hose, do not allow it to twist, otherwise the hose will be damaged or the connection will be loosened when under pressure; the hose installed between moving objects should be reserved with sufficient length and avoid friction with other objects.
Hydraulic rubber hoses often rub against hard objects during use. It is recommended to use spring protection sleeves outside the pipes. If the ambient temperature of the hose is too high or too low, it will affect the life of the hose and its ability to withstand pressure. Therefore, the hose should be used within its allowable range, and the system whose operating temperature is not within its allowable range for a long time should use a hose sheath. . During the use of the hose, if it is a special medium, ensure that the inner and outer layers of the hose, the joints, and the sealing ring are compatible with the medium. According to pressure and flow. The pressure determines the number of layers of the hose, and the flow rate determines the inner diameter of the hose, then the connection type at both ends, welding type, flare type, card sleeve type, flange type, etc., and whether it is straight or 90 degrees or 45 degrees.
