Powder equipment troubleshooting tips to quickly locate problems

In powder processing, equipment failure can affect production progress and product quality. Scientific troubleshooting techniques can help to quickly locate the problem and solve it in a timely manner. The following is a practical method to introduce powder equipment troubleshooting from multiple dimensions.

First, the observation method: the initial diagnosis of signs of failure

Observation is the most basic diagnostic method. First, check the appearance of the equipment to see if there is obvious mechanical damage, such as deformation of parts, cracks, or loose connections, detachment and so on. Secondly, pay attention to the state of the equipment when running, observe whether the transmission parts (such as belts, chains) slipping, running phenomenon; observe the vibration of the equipment, abnormal violent vibration is often a sign of bearing wear, rotor imbalance and other problems. In addition, but also pay attention to the temperature changes in the operation of the equipment, can be detected by infrared thermometer motor, bearings and other key parts, the temperature is too high may be insufficient lubrication or load caused by too large.

Second, listen to the sound method: identify abnormal sound

Different equipment failure will produce different characteristics of the sound. Normal operation of the powder equipment, the sound of the components running smoothly and regularly. If there is an abnormal noise, you need to carefully identify. Through the daily accumulation of equipment normal operation of the sound characteristics, can be more keen to capture the fault signal.

Third, the analytical method: combined with parameters and conditions of judgment

Referring to the operating parameters of the equipment is the key to accurately diagnose the fault. Operators need to be familiar with the range of parameters during normal operation of the equipment. When the parameters appear abnormal fluctuations, analyze the cause by combining the equipment working conditions. In addition, the operating time of the equipment, the cumulative working hours and other data can also be used as a diagnostic reference.

Fourth, segmentation method: narrowing the scope of the failure

When it is impossible to directly determine the failure point, can be used in a segmented way. Take the powder conveying system as an example, you can start from the feeding end, and check the conveying pipes, valves, fans and other components section by section. First confirm whether the feeding is smooth, then check whether the pipeline is blocked, whether the connection is leaking, and finally check whether the air volume and air pressure of the fan are normal. For the complex equipment system, it can be divided into power system, transmission system, control system and other modules, by testing the function of each module one by one, to narrow down the scope of failure.

Fifth, comparison method: reference to normal equipment or historical data

If there are a number of the same type of powder equipment, faulty equipment and normal operation of the equipment can be compared to observe the two in the operating state, the parameters of the performance of the differences, and quickly lock the problem. In addition, you can also refer to the equipment historical operating data and fault records, to analyze the occurrence of similar fault patterns and solutions.

Mastering the above troubleshooting skills, combined with the accumulation of daily maintenance experience, operators can more efficiently locate powder equipment failures, take timely maintenance measures to reduce equipment downtime, to ensure stable production operation.
