Air compressor as a vital power equipment in industrial production, its stable and efficient operation is directly related to the enterprise's production efficiency and product quality. Because of its complex mechanical structure, the performance and service life depends largely on the effectiveness of routine maintenance management. The following are the main points of daily maintenance and management of air compressors to help enterprises build a scientific and perfect maintenance management system to ensure its safe, stable and efficient operation.

First, the establishment of a perfect routine maintenance management system

(A) to develop a detailed maintenance plan

According to the type of equipment, operating conditions and use of the environment, customised personalised maintenance plan. For example, 24-hour continuous operation of the heavy load air compressor, to shorten the maintenance cycle; in high temperature, high humidity, dust and other harsh environments, to strengthen the maintenance of the filtration system.

Clearly defined maintenance projects, cycles and responsible person. Routine maintenance includes equipment appearance check (any oil leakage, water leakage, air leakage), oil level check (to ensure that the lubricant oil level is normal), oil temperature check (to monitor the temperature, to avoid anomalies), exhaust temperature check (to ensure that in the permissible range), filter check (blocked when cleaned up or replaced), drainage check (check the relevant components, timely discharge of condensate); regular maintenance is to replace the lubricating oil (according to the operating time and oil condition), replacement of oil (according to the operating time and oil condition), replacement of oil (according to the operating time and oil condition), replacement of oil (according to the operating time and oil condition), replacement of oil (according to the operating time and oil condition), replacement of oil (according to the operating time and oil condition). Regular operation), replacement of oil separator core, filters and other wear parts (according to the manufacturer's recommended cycle), check and tighten the bolts, check the motor and electrical system, check the safety devices (such as safety valves, pressure switches, to ensure that they are sensitive and reliable).

(ii) Define maintenance procedures and standard operating procedures (SOPs).

Establish detailed operating procedures and precautions for each maintenance item. For example, when replacing lubricating oil, empty the old oil first and add new oil after cleaning the oil tank.

Let all maintenance personnel be familiar with and strictly implement the SOPs, and provide regular training to maintenance personnel to enhance their professional skills and safety awareness.

(iii) Establish equipment files and maintenance records.

Establish an independent equipment file for each air compressor to record basic information, such as model, serial number, date of purchase, etc..

Detailed records of the content, time and results of each maintenance, maintenance records should have a list of maintenance projects, replacement of parts list, equipment operating parameters (such as oil temperature, exhaust temperature, pressure, etc.), found that the problem and measures to deal with the maintenance personnel to sign the confirmation and other content, and regular analysis, assessment of the operating conditions of the equipment, the timely discovery of potential problems, and the development of targeted maintenance plans.

Second, strengthen the daily inspection, timely detection and resolution of problems

(A) the development of inspection routes and inspection items

Combined with the layout of the equipment and operating procedures, to develop a reasonable inspection route, so that inspectors can fully inspect the equipment parts.

Clearly inspect the inspection items, standards and frequency. For example, check the oil level, exhaust temperature and other key parameters every two hours.

(ii) Equipped with necessary inspection tools and instruments

Equip portable thermometers, pressure gauges, vibration meters and other inspection tools to accurately measure the equipment on a regular basis and detect abnormalities in time.

With the help of online monitoring system, real-time monitoring of equipment operating status, such as monitoring lubricant temperature, pressure, vibration and other parameters and set alarm thresholds.

(iii) Timely processing of problems found in inspections

Inspection of small problems, such as filter clogging, loose bolts, etc., to immediately repair or take temporary measures.

Problems that can not be solved on-site, timely report, arrange for professional maintenance, to avoid the deterioration of the problem affecting the operation of the equipment.

Third, pay attention to lubrication management

(A) choose the right lubricant

According to the equipment manufacturer's recommendations, select the lubricant that meets the requirements based on the equipment's working temperature, load, speed and other factors.

Regular testing of lubricant viscosity, acid value, moisture and other quality indicators, deterioration of timely replacement.

(ii) Regular lubricant replacement

According to the equipment running time and lubricant status, reasonable development of oil change cycle, to prevent lubricant deterioration affect the performance of the equipment.

Thoroughly clean the oil system when replacing the oil to prevent impurities from mixing with the new oil.

(iii) Regular cleaning of oil filters

Regularly check and clean the oil filter to ensure that the lubricant is clean.

Replace the oil filter element when necessary.

IV. Other Precautions

(i) Keep the equipment clean

Clean the surface and surroundings of the equipment regularly to prevent dust accumulation.

Prevent debris from entering the interior of the equipment and affecting operation.

(ii) Regularly check the safety devices

Regularly check the safety valves, pressure switches and other safety devices to ensure that they are sensitive and reliable.

It is strictly prohibited to adjust the setting value of the safety devices at will.

(C) Do anti-freezing measures

Under the cold environment, take appropriate anti-freezing measures, such as adding antifreeze, good insulation.

Empty the cooling water in time when stopping the machine to prevent the equipment from freezing.

(D) Do spare parts management

According to the operating conditions of the equipment and maintenance plan, reasonable reserves of necessary spare parts.

Ensure that the quality of spare parts is reliable, do not use poor quality spare parts.

Through the above measures, the enterprise can enhance the operation reliability and service life of the air compressor, reduce maintenance costs, and provide a strong guarantee for safe production. We hope that these points can give effective guidance and help in the actual maintenance work, and help the air compressor to maintain a good state at all times.
