On-site diagnosis of electric forklift price hydraulic transmission system failure judgment

 

Before understanding the fault diagnosis of electric forklift price hydraulic transmission system on site, we need to learn from forklift manufacturers in china some conventional methods that are used in most hydraulic system fault diagnosis, which are divided into empirical method, experimental method, computer method and replacement method. . These four methods have their own advantages and disadvantages. As for which method to use, we still have to analyze the specific problems in detail.

Let me talk about the empirical method first. This method can only be done when the staff has a certain level of work experience. With many years of practical experience, they are able to judge the failure of the electric forklift price hydraulic transmission system. But if it is only based on empirical judgment, it is easy to cause blind operation.

Let's talk about the experimental method of forklift manufacturers in china. This method uses a fault detector to test the faulty system to determine the cause of the fault. This is very similar to the computer method, which uses expert system software to perform fault diagnosis and analysis on the electric forklift price hydraulic system, but this method is expensive and very complicated to operate. Look at the replacement method. This method uses component replacement or analogy to determine the location of the fault, but this method is blind.

Therefore, none of the four methods mentioned above by forklift manufacturers in china are very suitable, but we can organically combine the above methods, such as the combination of empirical method and replacement method, the specific steps are as follows:

First understand the failure phenomenon, understand how the electric forklift price fails, or check whether the equipment has been adjusted with the relevant components, observe the failure phenomenon; then analyze the working principle of the structure, understand the structure of each component, the characteristics of the working principle, and each according to the performance of the failure. Item analysis. Generally, we observe whether the oil level is normal, whether the oil quality and the vibration amplitude of the system are abnormal. Then there is the size of the sound produced by the system, touch the hydraulic components such as pumps, valves and pipelines with your hands, and smell whether the hydraulic oil is deteriorating or not.

In general, according to the above process of forklift manufacturers in china, the hydraulic system failure of electric forklift price can be effectively judged.
