In industrial production, compressed air post - treatment equipment plays a crucial role in ensuring the quality of compressed air and the stable operation of production equipment. Effective daily maintenance and management can extend the service life of equipment, reduce operating costs, and improve production efficiency. Next, we will elaborate on the key points of daily maintenance and management of compressed air post - treatment equipment.

1. Formulate a maintenance plan

According to the frequency of equipment use, working environment, and the manufacturer's recommendations, formulate detailed daily, weekly, monthly, and annual maintenance plans. Daily maintenance includes checking the operating status of the equipment, monitoring pressure and temperature, etc. Weekly maintenance can involve cleaning the filter and inspecting the drainage system. Monthly maintenance includes checking vulnerable parts and testing the electrical system. Annual maintenance covers comprehensive overhauls and performance tests, etc. Meanwhile, establish a record file for each maintenance, recording information such as maintenance time, content, replaced parts, and equipment operating parameters, so as to track the operating status of the equipment and promptly detect potential problems.

2. Key points for maintenance of key equipment

Air filter: The air filter can filter dust and impurities in the compressed air to ensure the normal operation of subsequent equipment. It is necessary to regularly check the filter element of the filter. If the filter element is blocked or dirty, it should be replaced in time. Generally, the filter element should be replaced every 1 - 3 months according to the use environment and frequency. At the same time, check whether the filter housing is damaged and whether the seal is good to prevent unfiltered air from bypassing.

Dryer: The dryer is used to remove moisture from compressed air. Common types are refrigerated dryers and adsorption dryers. For refrigerated dryers, it is necessary to check the refrigeration system daily to ensure that components such as the compressor, condenser, and evaporator are operating normally, and observe whether the refrigerant pressure and temperature are within the normal range. Regularly clean the condenser and evaporator to remove surface dust and dirt to ensure heat exchange efficiency. Check the drainage system to ensure that the automatic drainer works normally and prevent the accumulation of condensed water. For adsorption dryers, it is necessary to regularly check the status of the adsorbent. If the adsorbent is invalid or saturated, it should be replaced in time. Check the regeneration system to ensure that the regeneration process is carried out normally.

Air receiver tank: The air receiver tank can stabilize the compressed air pressure and store a certain amount of compressed air. Before each start - up, check the appearance of the air receiver tank for abnormalities such as deformation, corrosion, and cracks. Regularly check safety accessories such as safety valves and pressure gauges to ensure their sensitivity and reliability. The safety valve should be calibrated once a year, and the pressure gauge should be calibrated once every six months. Manually drain water every week to remove condensed water in the tank and prevent water accumulation from corroding the tank body.

3. Troubleshooting and handling of common faults

Abnormal pressure: If the compressed air pressure is too high or too low, first check the working status of the compressor and see if there are any leakage points. If the pressure is too high, it may be due to a faulty safety valve or a malfunctioning pressure regulating valve, and the corresponding components need to be repaired or replaced. If the pressure is too low, it may be due to a blocked filter, pipeline leakage, compressor failure, etc. Troubleshoot and solve the problems one by one.

Excessive water content: If the water content in the compressed air exceeds the standard, check whether the dryer is working normally, such as the refrigeration effect of the refrigerated dryer and the performance of the adsorbent in the adsorption dryer. Check whether the drainage system is blocked and clean the drainer and pipeline in time.

Filter blockage: When the pressure difference between the inlet and outlet of the filter is too large, it indicates that the filter element may be blocked, and the filter element needs to be replaced in time. At the same time, check whether the pre - filter at the front end of the filter is working normally to prevent large particles of impurities from entering the main filter.

4. Training of operators

Provide professional training to equipment operators to make them familiar with the equipment structure, working principle, operating procedures, and maintenance points. The training content includes the steps of starting and stopping the equipment, daily inspection items and methods, judgment and handling of common faults, etc. Only when operators have sufficient professional knowledge and skills can they better carry out daily maintenance and management of equipment, timely find and solve problems, and ensure the safe and stable operation of equipment.

The daily maintenance and management of compressed air post - treatment equipment is a systematic and detailed work. By formulating scientific and reasonable maintenance plans, strengthening the maintenance of key equipment, timely troubleshooting and handling faults, and improving the professional quality of operators, we can ensure that the equipment is always in good operating condition, provide high - quality and stable compressed air for industrial production, and promote efficient production.
