How To Identify Hydraulic Tool Leaks And Other Problems That Might Need Repairs
In order to identify the causes of hydraulic tool problems, you need to have a basic knowledge of how a hydraulic tool works. These hydraulic systems consist of a pump, a set of control valves, and a set of hydraulic hoses with a fluid capable of transmitting power. The system has a number of reservoirs, called accumulators, which store fluid under relatively high pressure. The following hydraulic information will help you identify issues with your tools that need repairs:
Hydraulic Tank Leaks
A hydraulic tank keeps hydraulic fluid in a tool from leaking out. It accomplishes this by containing a constant pressure to prevent fluid from leaking. If the pressure drops or rises too much, the fluid might start to leak out.
The hydraulic tank is usually made of steel but can also be made of aluminum. A steel tank is stronger than an aluminum tank, but an aluminum tank is lighter. If there is a problem with your tool's hydraulic tank, it needs to be repaired before it causes damage.
Hydraulic Pump Problems
Hydraulic pumps are devices driven by fluid pressure, usually oil, that move objects like pistons, drums, and hoses. Hydraulic pumps are an important part of hydraulics and hydraulic machinery. They push fluid around and provide power. If something breaks, they stop working. If parts of a pump wear out, they need to be replaced.
Hydraulic pumps have different components that can fail. Some of these parts include valves that move the fluids. There are also seals and gaskets that can fail and cause the system to leak. These issues need to be repaired before they cause the pump to fail or damage the tool.
Filters and Hydraulic Manifolds
Hydraulic systems can have filters, which remove particles from the flow of hydraulic fluid. The particles can clog the filter, reducing or cutting off the hydraulic fluid's flow. When that happens, the hydraulic pump has to work harder to keep the equipment moving. When a filter isn't working properly, the hydraulic fluid can overheat, reducing the life of the equipment.
Hydraulic manifolds are devices that connect two or more hydraulic circuits, so that fluid can flow from one circuit to another. Manifolds allow one circuit to be turned off without affecting the others. Manifolds often consist of multiple valves that control the flow of hydraulic fluid. When a hydraulic manifold leaks hydraulic fluid, it wastes water and energy. Manifolds and filters also can be sources of more serious problems, such as pressure surges in the hydraulic system. Pressure surges can damage pumps, hoses, and other equipment.
