How does the matching degree of Hydraulic Hose and connector affect system efficiency?

In hydraulic systems, the matching degree of Hydraulic Hose and connector has a crucial impact on system efficiency.
The size matching of hydraulic hose and connector is the basis. If the inner diameter of the hose does not match the connector, the fluid will cause throttling or turbulence at the connection. For example, when the inner diameter of the hose is smaller than the inner diameter of the connector, the fluid will be hindered when passing through, the pressure loss will increase, and the system will need to consume more energy to maintain the flow, thereby reducing efficiency; on the contrary, if the inner diameter of the hose is larger than the inner diameter of the connector, the connection may not be tight, resulting in leakage, which will also affect the system efficiency and working stability.
The material compatibility of the two should not be ignored. Hydraulic hoses usually have a variety of materials, such as rubber, polytetrafluoroethylene, etc., and connectors also have different metal or plastic materials. If the materials are incompatible, chemical reactions may occur when they are in long-term contact with hydraulic oil or media in the working environment, causing aging, embrittlement of the hose or corrosion of the connector, which will affect the sealing performance and service life, and reduce the efficiency of the system due to leakage or failure.
The matching of the connection method is also critical. Different hydraulic systems require different connection methods, such as crimping, threading, flange, etc. Inappropriate connection methods may lead to loose installation, difficult disassembly or loose sealing. For example, if the crimping joint is not crimped enough or too much, it will affect the reliability of the connection, easily leak, and affect the system pressure transmission and efficiency.
In addition, it is also very important to match the pressure rating of the hydraulic hose and the joint. If the pressure rating of the hose is lower than the working pressure of the joint or system, the hose may rupture or swell locally, causing leakage and system failure; if the pressure rating is too high, it may increase costs, and the flexibility and efficiency of the system may be affected due to the hose being too rigid.
