Powder hydraulic machine in the use of the failure can not be avoided, specifically the following reasons.
A simple fault diagnosis method is the most common, it is to rely on maintenance personnel with personal experience, using simple instrument according to the hydraulic system failures, objective by ask, watch and listen, touch, smell and other methods to understand the system work, analysis, diagnosis, determine the cause and position of the fault. The specific measures are as follows:
1) ask the equipment operator to understand the operation status of the equipment. Including: hydraulic system hydraulic pump is normal; there is no abnormal phenomenon; the cleanliness of the time and the results of hydraulic oil detection; filter cleaning and replacement; before failure on hydraulic components of a regulation; whether the replacement of sealing components; hydraulic system before and after the fault occurred and what is not a normal phenomenon; the past system what is the fault, how to eliminate the need to understand, one by one.
2) to see the actual situation of the hydraulic system work, observe the system pressure, speed, oil, leakage, vibration and other issues of whether there is a problem.
3) to listen to the sound of the hydraulic system, such as: the impact of sound; pump noise and abnormal sound; to determine whether the normal hydraulic system.
4) to touch temperature rise, vibration, crawling and the tightness of the joint position to determine whether the working state of the moving parts.
The powder hydraulic machine used in the process to find the reasons for failure, to solve scientific and reasonable according to the specific conditions, such as hydraulic machine parts surface pollution, most of the reason is that the oil outflow is the general machinery, hydraulic components outflow from the gap, so this time to do some parts replacement otherwise, in the process of using the equipment will cause paralysis of the operation system will not work, so the oil leakage problem to do timely treatment.
