What Is a Hydraulic Hose Assembly?

A hydraulic hose assembly is a series of hoses used to deliver liquid, the resulting pressure of which helps to power machines. The assembly is commonly found in construction and manufacturing equipment known as hydraulic machines. Hoses are arranged so that the machine operator can reduce or increase pressure and thus change the amount of power exerted.

The amount of power exerted by a hydraulic hose assembly depends partly on the size of the hoses. Which size to pick depends upon the power needs and capacity of the machine. An improper fit can have a dramatic effect on productivity and potentially harm the machine or its operator. There are several industry specifications which can be used to find the proper fit for each piece of equipment.

Another key part of a hydraulic hose assembly is its fittings. These connections hold the assembly together and in the proper place. They consist of valves, nuts, seals, and other similar materials. These are also prepared to industry specifications in order to ease the process of finding an adequate fit.

For the best performance, a hydraulic hose assembly will typically need to be precisely fitted. If the hoses are too small, they will not be able to stand up to the level of required flow. Hoses that are too large can still function, but are less flexible and can cost more to replace.

The length of the hoses in a hydraulic hose assembly must also be properly measured. They need to be long enough to handle fluid capacity and delivery. If there is too much hose, it can impede the efficiency of the machine, increase weight, and unnecessarily increase the cost of maintenance.

A hydraulic hose assembly is also typically made to withstand a certain level of temperature. The heat resistance of the hoses and the way in which they are installed are two of the most important elements of managing high temperatures. Purchasing materials in the appropriate industrial grade and regularly checking for wear can help to ensure that the proper materials are being used.

Hydraulic hose assemblies must also be installed properly if they are to work safely and efficiently. This includes checking the equipment for fit and overall condition before installation and at regular intervals afterwards. It is also important that the assembly is arranged so that hoses are not excessively bent. This can increase the durability and efficiency of the assembly.
