Hydraulic Hose Fittings Under Pressure

Hydraulic hoses differ from the standard rubber hoses

. The hydraulic hose has a braided stainless steel, or a woven nylon sleeve contained on the interior of the rubber casing and on the exterior. The exterior covering protects the hose from injury by cutting or rubbing against any machinery while in use. A hydraulic hose could also contain at its center an interior flexible tube made of Teflon. The stainless steel sleeve permits the hydraulic hose to undergo large amounts of pressure. The hydraulic hose fittings require an attachment which is crimped by a machine to allow the coupling to undergo the great pressure required as the system operates.

The hydraulic system operates with at least two hoses. The first is for high pressure, and the second hose is for a low pressure return. These hoses are connected to the hydraulic pump and they transport the hydraulic fluid to the hydraulic cylinder. The hydraulic operating system is driven either by electricity or by the engine of the vehicle.

There are different hoses that are required for the various industries. Oftentimes, there are two hoses that must be connected to create a longer hose. The hydraulic hose fittings will connect two or more hoses together. Many hydraulic hose fittings can connect various types of hoses together. These types of hydraulic hose fittings are for purposes of a temporary or a permanent connection.

The assembly of hydraulic hoses is positioned so that the machine operator will reduce or increase the pressure and the amount of power needed. The size of the hoses will depend on the amount of power that can be used. The size to use is based upon the power and the capacity of the machine. The result of an unacceptable match would be ineffective productivity and possible harm to the operator as well as the machine. Industry specifications are strictly followed to determine the proper fit for the equipment pieces.

The hydraulic hose assembly relies on the integrity of the fittings. This is what holds the assembly in the proper place and connects it together. The fittings consist of seals, valves, nuts, and other like materials. These must also meet industry specifications to allow for the proper fit.

For optimal job performance, the hydraulic hose assembly should be precisely fitted. A hose that is too small will not withstand the level of pressure that is required. For hoses that are too large they will still complete the job but are not as flexible and will be more costly to replace.

The length of the hoses must be properly measured. They must be long enough to handle the fluid and delivery capacity. As too long of a hose will slow down the efficiency of the machine, and create an unnecessary cost in the maintenance on the machine.

The hydraulic hose assemble has been designed to maintain a preset level of temperature. The hoses are constructed for heat resistance and with the proper manner in which they are installed are critical to their ability to withstand high temperatures.

The hydraulic hose fittings are mostly designed for a quick release. This type of hose fitting is to allow the replacement and removal to avoid bleeding the system of air. In the industries of construction and farming the equipment is designed for a quick disconnection. This method allows for the exchange of tools as well as the power sources.

For the equipment to work safely and efficiently hydraulic assemblies need to be installed correctly. The equipment must be checked for the proper hydraulic hose fittings; the hoses are the correct size and not have any damage by an excessive bending or crimping to assure the durability, and efficiency of the assembly.
