What is a Hydraulic hoses
Hydraulic hoses are rubber pipes with reinforced with textile, wire braid, or wire spiral layer in the middle, they can bear specific pressure when put into use. they convey fluid power from the hydraulic pump to the actor to accomplish specific actions on the machine.
Hydraulic rubber hoses often find their use in some engineering machines in the field of construction, agriculture, forest, mine, and even some residential cases.
What is the construction of a Hydraulic hoses
Generally speaking, a hydraulic rubber hose consists of three-layer from the inner to the outer cover.
The inner tube is an oil-resistant synthetic rubber, its inner wall touches the hydraulic fluid directly, and it must be compatible with the hydraulic fluid.
The middle layer is a reinforced layer with textile braided, steel wire braided, or steel spiral around the inner tube, it functions to support against the pressure from the inner fluid power.
The outer cover is weather and oil-resistant rubber, it wraps the reinforced layer and protects them against any corrosion and destruction.
