Subjects: How to Fit High Pressure Hydraulic Hose Fittings?


High Pressure Hydraulic Hose Fittings’ Fitting:

High pressure hydraulic hose is mainly used in hydraulic support, oil field drilling, mine is suitable for engineering construction, lifting, transportation, metallurgy forging press, mining equipment, vessels, injection molding machinery, agricultural machinery, all kinds of machine tools and various industrial departments mechanization and automation of hydraulic system with certain pressure and temperature of oil in the base (such as mineral oils, soluble oil, hydraulic oil, fuel oil, lubricating oil) liquid, water-based liquids (such as emulsion, oil/water emulsion, water), such as gas and liquid transmission.

The fitting method of high pressure hydraulic hose can be roughly divided into internal thread method and external thread method:

1)      Internal Thread Method

This layout method is usually applicable to the situation where the working pressure is relatively low and the flow rate is relatively large. This connection method allows the diameter of the high-pressure fittings to be appropriately added, and its seal is primarily dependent on the sealing ring.

2)      External Thread Method

This layout method is primarily selected in the case of high pressure. When the working pressure exceeds 1,800bar, this cohesive method is mostly selected.This kind of fitting method is to press the locking nut through the connecting part of the external thread, and then make the sealing surface of the conical surface of the pipe segment and the sealing surface of the connecting part close together, play the sealing effect.The connected parts can also be jet accessories, such as high pressure nozzle, plane cleaning nozzle, three-dimensional rotary nozzle, or other high pressure hose.This connection method can be useful to avoid loose connection under chaotic construction conditions.
