The simple fault detection method is now used in most ways. It depends on the maintenance personnel, based on their own work experience, using the simple instrument panel, according to the common faults of the hydraulic transmission system, and objectively selecting the methods of asking, seeing, listening, touching and smelling to master the work of the system software, analyze, diagnose and clarify the cause and location of the problem, The specific methods are as follows:

1) Understand the operators of powder forming hydraulic press and master the operation of machinery and equipment. Including: whether the hydraulic transmission system works normally; Whether the hydraulic oil pump is abnormal; Time period and results of hydraulic oil cleanliness inspection; Cleaning and replacement of filter element; Whether the hydraulic system can be adjusted before common faults occur; Whether the sealing components have been replaced; What abnormal conditions have occurred in the left and right hydraulic transmission systems before and after common faults; What common faults occurred in the system in the past and how to eliminate them need to be mastered one by one.

2) Look at the actual operation of the hydraulic transmission system, and check whether there are problems in the working pressure, speed, hydraulic oil, leakage and vibration of the system software.

3) Listen to the sound of hydraulic transmission system, such as impact sound; Pump noise and abnormal sound; Distinguish whether everything is normal in the operation of the hydraulic transmission system.

4) Touch the level of temperature rise, vibration, crawling and tightness at the connection to judge whether the operation state of fitness components is normal.

In view of the problems arising from the whole application process of the powder forming hydraulic press, we should find the causes of common faults and realize reasonable treatment according to the actual situation. For example, the environmental pollution of the parts on the surface of the hydraulic press is mostly caused by the discharge of hydraulic oil from the mechanical equipment, which is generally discharged through the gap between the components of the hydraulic press. Therefore, we must do a good job in the disassembly and replacement of parts at this time, Otherwise, it will lead to hemiplegia of the whole machine and equipment in the adopted link, and the operation system software may not be able to complete the work. Therefore, the problem of oil leakage should be solved immediately.
