How to find the hydraulic fault caused

In the analysis and troubleshooting of the hydraulic system diagram, the main method is to "grasp both ends" -- that is, grasp the power source (oil pump) and actuator components (cylinder, motor), and then "connect the middle", that is, from the power source to the actuator through the pipeline and control components. "Grasping", to analyze whether the fault is in the oil pump, cylinder and the motor itself. "Intermediate" in addition to pay attention to the analysis of the fault is in the attachment on hydraulic components, but also pay special attention to figure out a system to move from one working state to another working state is to use which kinds of control mode, control signal whether is wrong, for the material object, one by one check, pay attention to between each main lines and main lines and control oil circuit between with and without mutual interference phenomenon resulting from the wrong, if there is a mutual interference phenomenon, to analyze how to use adjustment error, etc.

Second, use the cause and effect diagram to find hydraulic fault

The cause-and-effect diagram (also known as fish-bone diagram) analysis method is used to analyze the faults of hydraulic equipment, which can not only find out the primary and secondary causes of faults quickly, but also accumulate experience in troubleshooting.

Causal graph analysis, which can be used to closely combine maintenance management with fault finding, is widely used.

The fault diagnosis and state monitoring of hydraulic system are carried out with ferrography technology

Iron spectrum technology is mechanical wear of friction pair as the basic starting point, with the aid of iron spectrometer wear particles and other pollution particles in the hydraulic oil, iron spectrum is made, and then placed in ferrographic microscope and scanning electron microscope to observe, or according to the size, in turn, deposited on glass tube, optical method for quantitative detection. Through the above analysis, the important information about wear and tear in the system can be accurately obtained. On the basis of this, wear phenomena are further studied, wear conditions are monitored, precursors are diagnosed and system failure prediction is made.

Ferrography technology can be effectively used in detecting, monitoring, analyzing and fault diagnosis of oil pollution in hydraulic system of construction machinery, and has the advantages of intuitionistic, accurate and informative. Therefore, it has become a powerful tool for the diagnosis and analysis of hydraulic system faults in mechanical engineering.

According to the working practice, summarize the relationship table between the fault phenomenon and the cause of the fault (or provided by the manufacturer), which can be used for the search and treatment of general hydraulic faults.

Our company Yuhuan Kaitian hydraulic lubrication equipment Co., Ltd. to undertake all kinds of lubrication product design, production and manufacturing, installation, technical guidance, modification and other general contracting tasks. Contact: 13967670889 (Manager Zhao) Tel: 0576-87234521

Using the self-diagnosis function of the equipment to find hydraulic faults

With the continuous development of electronic technology, at present, many large and medium-sized construction machinery, the use of electronic computer control, through the interface circuit and sensing technology, its hydraulic system for self-diagnosis, and display on the fluorescent screen, use, maintenance can be based on the display of the content of the fault troubleshooting.
