The marine hydraulic hose assembly is an important connecting component of the marine hydraulic pump station, hydraulic cylinders, deck machinery, etc. The characteristic of the marine hydraulic hose assembly is easy installation, not limited by limited space, and is a commonly used hydraulic accessory in the marine hydraulic system. The connection methods include: sleeve type, flange type, cone sealing type, flared type, and so on. However, the procurement of marine hydraulic hose assemblies requires understanding of several important parameters to ensure product quality.
1. Maximum working temperature: The working temperature of the steel wire braided hydraulic hose is between -40 ℃ and 100 ℃. The working temperature of wire wound hydraulic hoses is between -40 ℃ and 120 ℃. Within this temperature range, the surface of the hydraulic hose shall not crack or leak oil.
2. Under the highest working pressure, there is no oil leakage or failure of the hydraulic hose.
3. The minimum throughput requirement is that the diameter of the hydraulic hose joint core must reach 90% of the diameter before extrusion after extrusion molding.
4. The length change of the hydraulic hose assembly under the highest working pressure must be within this range: steel wire braided hydraulic hose assembly: -4% -2%; Wire wound hydraulic hose assembly: -2% -2%.
