Precautions for the use of Wuhan automated test equipment:
　　 1. Check all power sources, air sources, and hydraulic sources of automated machinery.
　　 Power supply, air supply and hydraulic supply problems will often lead to failure of automation equipment. For example, power supply problems, including power supply failures in the entire workshop, such as low power supply, burned insurance, poor contact of power plugs, etc.; air pump or hydraulic pump is not turned on, pneumatic triple or double parts are not turned on, and the relief valve in the hydraulic system Or some pressure valves are not opened, etc. The following aspects should be included when testing automation equipment: 　　 Power supply, including the power supply of each device and the power supply of the workshop.
　　 Air source, including the air pressure source required by pneumatic devices.
　　 Hydraulic source, including the working conditions of the hydraulic pump required by the hydraulic device of the automation equipment. 　　 2. Check whether the sensor position of the automation equipment is offset.
　　 Due to the negligence of equipment maintenance personnel, the position of some sensors may be wrong, such as not in place, sensor failure, sensitivity failure, etc. Always check the sensing position and sensitivity of the sensor, adjust it in time if there is a deviation, if the sensor is broken, replace it immediately. In many cases, in addition, due to the vibration of automation equipment, most of the sensors will become loose after long-term use. Therefore, during routine maintenance, you should always check whether the position of the sensor is correct and whether it is firmly fixed.
　　 3. Check the relay, flow control valve and pressure control valve of automation equipment 　　 Relays are the same as magnetic induction sensors, they will also have ground adhesion after long-term use, so that the electrical circuit cannot be guaranteed and needs to be replaced. In a pneumatic or hydraulic system, the opening degree of the throttle valve and the pressure regulating spring of the pressure valve will also loosen or slip with the vibration of the equipment. These devices, like sensors, are components that require routine maintenance in automation equipment.
