Regardless of how big or small or how complex your hydraulic system is, one this for sure, performing regular hydraulic maintenance will have a big impact on its performance and its life span. With the help of a few maintenance tips, you will be able to protect the system from any damage while ensuring its longevity and maximum performance. This is also helpful in getting more savings on replacement and repair.
Check the Filter Indicators
The indicators help monitor the quantity of contamination that was caught by the filter. You can visually or electrically see the contamination level. When it shows that it has reached its max acceptable contamination-holding capacity, it should be replaced. When this is not checked, the filter would start to bypass the fluid and will not be able to protect the system from any contamination. Be sure to check the indicators, as well as the gauge-style indicator as they need to work properly.
Sample the Oil
Contamination is often the root of most problems that are encountered by the system. This causes blockages and could lead to wear in the hydraulic systems. By sampling the oil and testing it for solid particle contamination, water, and other unwanted constituents can help avoid the need for expensive repairs. The sample needs to be taken from a nominated sample point to guarantee consistency across measurements. Ideally, it is from a test point that is in an active return line. Doing it from a stagnant source or reservoir drain would result in wrong readings.
The temperature has a very big effect on the thickness of the oil and if it is outside of the working series of the system components, then it can greatly lessen the lifetime of the system. For example, low viscosity lessens the thickness of the film between all moving components, thus causing wear. On the other hand, high viscosity could cause so much pressure drops in the suction lines that lead to cavitation. The reservoir temperature usually differs from the definite working oil temperature. For this instance, a non-contact thermometer might be used on working lines.
Slowly decreasing function on a long period of time is expected in any type of hydraulic system. A quickly decreasing performance could be a forerunner for catastrophic failures. But by getting to know your system well by monitoring the actuator speed, temperature, case drain flow, speed, and oil levels will help prevent expensive failures.
Keep the Equipment Clean
Although grime and dirt on the exterior of the equipment are inoffensive, contamination could still enter the system when the hydraulic components are being disconnected for relocation or maintenance when the filter elements being are changed or when the oil is being added. As soon as the cylinder retracts, the contamination on its rod could get into the system under its wiper seal.By simply following these helpful hydraulic maintenance tips and ways you will be able to ensure that it will be at its best performance and will function for a much longer time.
