Diagnosis of non-standard automatic equipment defects four-step diagnosis of non-standard automatic equipment defect four steps.

1. Check all power source, air source and hydraulic source of non-standard automation equipment.

Problems with power sources, gas sources and hydraulic sources often lead to shortcomings in automation equipment. For example, the problem of power supply of non-standard automation equipment, including the defects of power supply in the whole workshop, such as low power power, safe burning, poor contact of power plug, etc.; The air pump or hydraulic pump has not opened, the pneumatic triplets or the two parts are not opened, the relief valve in the hydraulic system or some pressure valves are not opened. The test automation equipment should include the following aspects: power supply, including the power supply of each device and the power of the workshop. Air source, including air pressure source required for pneumatic equipment. Hydraulic source, including hydraulic pump requirements for non-standard automation equipment.

2. Check whether the sensor orientation of the automatic test equipment is offset.

Due to the negligence of the equipment maintenance personnel, there may be errors in the orientation of some sensors, such as the lack of the non-standard automation equipment, the defect of the sensor and the sensitivity of the sensor. Always check the sensor orientation and sensitivity of the sensor, the fault is dispatched in time, the sensor is presumed to be broken and replaced immediately. Many, in addition, due to the shaking automation equipment, most of the sensors in use for a long time, after bearing loose will happen, so in the daily maintenance to often check the orientation of the sensor is correct, whether fixed strong.

3. Check the relay, flow control valve and pressure control valve of automatic riveting device.

The relay is the same as the magnetic induction sensor, and the long term use will also show the adhesion of the iron, and then the non-standard automation equipment cannot guarantee the normal electrical circuit and the demand replacement. In the pneumatic or hydraulic system, the throttle valve opening and pressure regulating springs of the pressure valve will also follow the equipment's shiver and appear loose or slip. These devices are the same as sensors, and are part of the automation equipment that is required for daily maintenance.

4. Check electrical, pneumatic and hydraulic circuit connections.

Assume that none of the above three steps has any problem, so check all loops. Check whether the wires in the circuit of non-standard automation equipment are broken, especially if the wires in the wire slot are cut off by the grooves. Check if the windpipe has damaged creases. Check whether the hydraulic tubing is blocked. Suppose the trachea has a severe crease, which is immediately replaced. The hydraulic tubing should be replaced.
