Hydraulic System Fault Judgment Method

Methods for judging hydraulic system failures:

Hydraulic equipment is one of the common equipment in mechanical equipment, basically relying on hydraulic transmission to run from the system to the working device. There are many methods for judging the failure of hydraulic equipment at home and abroad. Generally, tools such as pressure gauges and flow meters are used to detect the operating speed of each part of the actuator and judge the failure. For example, in actual work, the surface temperature of parts is often measured. If the temperature is too high, it can cause the equipment to continue running.

Fault judgment should follow the following principles:

(1) Efficiency: The shutdown of hydraulic equipment often results in the shutdown of unit projects. In this case, it is useful to judge the equipment failure. Secondly, the speed of fault judgment is improved. The second is to require accurate judgment. The more accurate the results, the less cost and time it takes to remove obstacles. Therefore, the failure analysis should not be too rough, but should be as deep as possible.

(2) Simplicity: There are many interference factors on the construction site, and high-precision equipment may not be good at judging faults. On the contrary, some simple and direct analysis methods have a great impact. When identifying faults, the loading and unloading of equipment should be minimized to avoid adverse effects on the accuracy of hydraulic components.

(3) Accumulate experience: equipment maintenance and management personnel continue to learn and master hydraulic professional knowledge, understand system principles and the structure of each component, have strong fault judgment and identification capabilities, and avoid major fault losses.
