With the continuous development of industrial manufacturing, the usage and frequency of four-column hydraulic presses are also increasing. During the normal inspection, check which component is faulty, and then refer to the following methods to solve it. At the same time, do maintenance work to avoid such failures.
A. Auxiliary method for fault diagnosis of four-column hydraulic press
With the help of simple auxiliary parts, diagnose whether the hydraulic components of the hydraulic press are malfunctioning.
(1) Oil blocking method: blocking the oil ports of valve components and oil cylinders can diagnose whether these hydraulic components are leaking.
(2) Artificial reversing method: using the ejector rod to change the direction of valve components, it can diagnose whether the reversing valve is stuck.
B. Replacement method for fault diagnosis of four-column hydraulic press
Replace the same components on the four-column hydraulic press of the same type, structure and principle in the same position to prove whether the original hydraulic press components are normal.
C. Sensory method for fault diagnosis of four-column hydraulic press
The sensory method mainly includes observing the working state of the hydraulic press, using hearing to judge whether the hydraulic system is working normally, touching the temperature and working condition of the moving parts by hand, and smelling whether the oil has deteriorated.
D. Analysis method of failure diagnosis of four-column hydraulic press
The analysis method is a fault diagnosis method based on the working principle of the hydraulic system. Many hydraulic system failures can be solved by using analytical methods.
E. Special instrument testing for fault diagnosis of four-column hydraulic press
Special instrument detection is to use special hydraulic system fault diagnosis fault, this type of instrument can make quantitative detection of hydraulic system fault.
F. State detection method for fault diagnosis of four-column hydraulic press
There are many instruments used in the state detection method, usually mainly pressure sensors, flow sensors, displacement sensors and oil temperature detectors.
G. Empirical method for fault diagnosis of four-column hydraulic press
Hydraulic machine maintenance personnel are familiar with the mechanism and working principle of hydraulic components by mastering the hydraulic system, and comprehensively analyze the mechanical energy based on rich hydraulic machine repair experience.
