Section 1 Regular Inspection Plan

Regular inspection plan is the key to ensure the long-term and stable operation of KIMAIR air compressors. Through regular inspections, potential problems can be discovered in time, failures can be avoided, and the service life of the equipment can be extended. The following is a detailed regular inspection plan: 1. Daily inspection ▪ Operation status: Check whether the operating sound of the compressor is normal, and whether there is any abnormal noise or vibration. ▪ Pressure gauge: Observe the reading of the pressure gauge to ensure that it is within the normal range. ▪ Temperature: Check the temperature of the motor and compressor to ensure that they are not overheated. ▪ Lubricating oil: Check whether the oil level is within the normal range and whether the oil is clear. ▪ Filter: Check whether the air filter is blocked and clean or replace it if necessary. ▪ Safety valve: Ensure that the safety valve is in normal working condition and has no leakage. 2. Weekly inspection ▪ Electrical connection: Check whether all electrical connections are tight and whether they are loose or damaged. ▪ Belt: Check the tension of the belt and adjust or replace it if necessary. ▪ Cooling system: Check whether the cooling fan is running normally and whether the radiator is clean. ▪ Oil circuit: Check whether the oil circuit has leaks and repair it if necessary. ▪ Control system: Check whether the indicator lights and display screen on the control panel are normal and whether there are any alarm messages. 3. Monthly inspection ▪ Air filter: Thoroughly clean or replace the air filter to ensure smooth air intake. ▪ Lubricating oil: Check the quality of the lubricating oil and replace it if necessary. ▪ Cooling system: Clean the radiator thoroughly and check whether the blades of the cooling fan are damaged. ▪ Sensor: Check the accuracy of the temperature sensor and pressure sensor and calibrate them if necessary. ▪ Safety valve: Test the pressure relief function of the safety valve to ensure that it works properly. 4. Quarterly inspection ▪ Motor: Check the insulation resistance of the motor to ensure that it is within the safe range. ▪ Bearing: Check the wear of the bearing and lubricate or replace it if necessary. ▪ Control system: Check the connection wires of the PLC and sensor to ensure that there is no damage. ▪ Oil separator: Check the efficiency of the oil separator and clean or replace it if necessary. ▪ Gas system: Check the connection of the gas pipeline to ensure that there is no leakage. 5. Annual Inspection ▪ Comprehensive Inspection: Conduct a comprehensive inspection of the compressor, including the motor, compressor head, cooling system, control system, etc. ▪ Performance Test: Perform performance test to ensure that all indicators of the compressor meet the standards. ▪ Cleaning and Maintenance: Thoroughly clean all parts of the compressor to ensure that the equipment is clean and tidy. ▪ Record Maintenance: Record all inspection and maintenance contents to form a detailed maintenance report.

Section 2 Maintenance and Replacement Cycle

The maintenance and replacement cycle is an important measure to ensure the efficient operation of KIMAIR air compressors. Reasonable maintenance and replacement cycles can extend the service life of the equipment and reduce the occurrence of failures. The following is a detailed set of maintenance and replacement cycles: 1. Lubricating oil ▪ Replacement cycle: Replace the lubricating oil every 500 hours or 6 months, whichever comes first. ▪ Selection: Select the lubricating oil suitable for the compressor model to ensure that it has good lubrication performance and high temperature resistance. ▪ Inspection: Every time you change the lubricating oil, check whether there is leakage in the oil circuit to ensure that the oil circuit is unobstructed. 2. Air filter ▪ Replacement cycle: Replace the air filter every 1000 hours or 12 months, whichever comes first. ▪ Cleaning: Before replacement, clean the filter thoroughly to ensure smooth air intake. ▪ Inspection: Check whether the filter is installed firmly to ensure that there is no air leakage. 3. Belt ▪ Replacement cycle: Replace the belt every 2000 hours or 24 months, whichever comes first. ▪ Adjustment: Check the tension of the belt every time the belt is replaced and adjust it if necessary. ▪ Inspection: Check the wear of the pulley to ensure that the pulley surface is smooth. 4. Oil separator ▪ Replacement cycle: Replace the oil separator every 4000 hours or 36 months, whichever comes first. ▪ Inspection: Check the efficiency of the oil separator to ensure that it can effectively separate oil and gas. ▪ Cleaning: Before replacement, clean the oil separator thoroughly to ensure that it is clean and tidy. 5. Sensor ▪ Calibration cycle: Calibrate the temperature sensor and pressure sensor every 12 months. ▪ Inspection: Check whether the sensor is installed firmly to ensure its normal operation. ▪ Replacement: If the sensor is found to be damaged or malfunctioning, replace it with a new sensor in time. 6. Safety valve ▪ Test cycle: Test the pressure relief function of the safety valve every 6 months. ▪ Inspection: Check whether the safety valve is installed firmly to ensure its normal operation. ▪ Replacement: If the safety valve is found to be damaged or malfunctioning, replace it with a new safety valve in time. 7. Cooling system ▪ Cleaning cycle: Clean the radiator every 6 months. ▪ Inspection: Check whether the blades of the cooling fan are damaged to ensure its normal operation. ▪ Replacement: If the cooling fan is found to be damaged or malfunctioning, replace it with a new cooling fan in time. 8. Motor ▪ Inspection cycle: Check the insulation resistance of the motor every 12 months. ▪ Lubrication: Lubricate the motor bearing every 6 months. ▪ Replacement: If the motor is found to be damaged or malfunctioning, replace it with a new motor in time. Through reasonable maintenance and replacement cycles, you can ensure that the KIMAIR air compressor is always in the best working condition, improve production efficiency and reduce maintenance costs.
