Four diagnostic methods for hydraulic system failure - News - Global IC Trade Starts Here.

The hydraulic system is more reliable when used, but it is difficult to find the cause of the fault in case of problems, and it may cause the maintenance personnel to spend a lot of time to check, resulting in long-term mechanical shutdown, resulting in a large loss of production. The failure of the hydraulic system is not impossible to judge. Let's take a look at the four basic troubleshooting methods. Observation of hydraulic system failure

When the hydraulic system fails, we should first observe whether the system configuration is correct, and whether the radiator, pump, valve, etc. are working well. Secondly, we can observe whether the operating speed of the actuator is normal and whether the pressure value in the hydraulic system is abnormally fluctuating. Finally, we can observe if the oil is clean and there is a leak at each mechanical joint.

Hydraulic system failure listening

The failure of the hydraulic system may also be rooted in the way of listening. The content of the listening is mainly to judge whether there is noise, the source of the noise, the size of the noise, and whether the noise has regularity. The parts of the hydraulic system where noise is likely to occur include hydraulic pumps, motors, valves, oil lines, and the like.

Touch of hydraulic system failure

The failure of the hydraulic system is judged by touch. It is mainly whether the temperature of the component is abnormally increased, whether there is abnormal vibration during the movement of the machine, whether the mechanical thread connection is tight and whether there is oil leakage in the place where the eye cannot be seen. Happening.

Smell of hydraulic system failure

The failure of the hydraulic system may be caused by deterioration of the oil, which requires us to smell the smell of the oil and determine whether the oil has deteriorated. Short circuits or high temperatures in the hydraulic system can also burn components, and the way they smell can help to find out where the burn is.
