Analysis of Fault Finding Methods for Pneumatic Tools

- Sep 07, 2019-

Pneumatic tools for shearing and crushing of various metal sheets, pipes, plastic nozzles, etc., because multiple pieces of wood can be crushed at one time from one side, saving labor, reducing costs, and improving operations. Speed, and thus improve the rationality of production. In the process of operation and use of pneumatic tool system, it is inevitable that such problems will occur. In order to avoid the problem of failure, it is necessary to understand the fault finding method, if it is handled and avoided. The following is a description of how to find and handle the fault problems of several pneumatic tools:




    1. Find the problem of the pneumatic tool failure according to the pneumatic tool system diagram.




    When looking for a fault problem based on the pneumatic tool system diagram, the key method is to "grab the two ends", that is, firmly grasp the power source of the pneumatic tool pump and the actuators of the pneumatic tool cylinder and the pneumatic tool motor, and then “Connected to the middle”, that is, the piping and control components that need to be connected from the power source to the execution components. When "grabbing two ends", it is necessary to analyze whether the problem of failure is generated on the pneumatic tool motor. In addition to the need to focus on the analysis of the fault problem, it is not necessary to generate the pneumatic tool components on the connected road, but also need to pay special attention to and clearly understand which control method is used when the system is transferred from one working condition to another. .




    2. Use the causal map to find the fault of the pneumatic tool system.




    The causal map is also called the fishbone diagram. Using this graph analysis method to analyze the fault problem of the pneumatic tool system, it can quickly and easily find the primary and secondary factors of the fault problem, and can accumulate the experience of fault problem clearing. Causal graph analysis is a very common method of using maintenance management and query faults.




    Summary: The above two are commonly used, which can easily and quickly find out the fault problem of the pneumatic tool system, and facilitate timely measures to deal with and prevent the failure of the hydraulic system.
