A hydraulic system is a type of drive technology that utilises incompressible fluid in moving energy from an electric motor to an actuator. This system is usually maximised in providing high power density as well as matching the rapid changes in load requirements. Hydraulic lifts, brakes, steering, and other pieces of heavy equipment enjoy the capabilities and functionalities of hydraulic systems.
While hydraulic systems can truly help different pieces of equipment on their respective functions, they can still experience some issues over time. And as these systems encounter serious problems, they can easily cause sudden shutdowns, loss of productivity, huge repair costs, and other performance issues.
To avoid encountering major problems and issues with hydraulic systems, here are some things that you should do to minimise their downtime as well as improve their reliability.
Filter Hydraulic Fluid
Most hydraulic failures have been traced back to the presence of contaminated hydraulic fluid within the hydraulic system. As small particles enter the stream of hydraulic fluid, it can easily cause performance issues to the system and its accompanying equipment or device. To minimise hydraulic failures, the hydraulic fluid must be filtered through a filtration unit whenever it is stored in a tank or enters the system. The said unit must be capable of flushing and filtering both particulate matter and water.
Get Rid of Moisture
During the hot summer months, hydraulic systems tend to perform poorly as an intense amount of moisture accumulates on their components. As the moisture infiltrates the system, its components are easily exposed to oxidation and corrosion, which will eventually damage them in the long run. To get rid of moisture, you must utilise desiccant breathers. These components are known for removing moisture and preventing the said element from reaching and creeping into the hydraulic fluid.
Keep Everything Cool
One part of hydraulic systems that are directly affected by heat is the hydraulic fluid. Hydraulic fluid tends to lose its service life and the ability to lubricate as the temperatures rise above 60 degrees Celsius. Additionally, the gradual increase of temperatures beyond 60 degrees Celsius causes hydraulic fluid to lose more life until it completely fails, causing the accompanied hydraulic system to experience a frequent breakdown. Keeping the temperatures below 60 degrees can help the fluid perform optimally.
To minimise downtime and improve overall reliability, hydraulic systems must be maintained regularly. Preventative maintenance, in particular, can help address any potential problems that the systems may have as they operate. Some system components that must be maintained regularly include reservoirs, breathing caps, oil level switches, and heat exchangers.
Before entering the reservoirs, the hydraulic fluid must be filtered thoroughly. Breather caps should possess a 10-micron rating and must be changed twice a year. As for minimising oil loss, you may want to look for the warning switch in the reservoir and eliminate it. Going straight to shutdown mode once the hose ruptures can easily reduce hydraulic fluid loss. Removing the unwanted buildup of sludge and soft deposits on heat exchanger must likewise be done to maintain hydraulic fluid temperatures.
