Ingersoll Rand air compressor maintenance method steps and procedures and precautions
1. Explain the daily maintenance and operation record table of the air compressor
The daily maintenance and overhaul records of Ingersoll Rand air compressors can be recorded regularly or irregularly, or after overhaul and maintenance. Accurate records are helpful for timely analysis and elimination of faults when the air compressor fails. The main contents of the maintenance record include inspection, cleaning, adjustment, supplement, replacement and corresponding time. The maintenance records and operation records of screw air compressors are shown in Table 1 and Table 2, respectively.
2. The significance of air compressor maintenance
Ingersoll-Rand air compressors are maintained in order to have the best working condition. Proper maintenance can increase the service life of the entire machine and greatly reduce the time of downtime. The maintenance cycle of screw air compressors provides reference time for customers. If the air compressor is installed in a clean and low temperature environment, the service cycle can be extended appropriately. The correct service cycle should be formulated according to the environment of the air compressor. .
3. What are the daily maintenance items of the air compressor?
The daily maintenance items include:
Check the coolant level and add it in time;
Replace the coolant;
Clean or replace the air filter;
Cooler after cleaning;
Clean oil cooler;
Cleaning water separator;
Replace the oil filter;
Replace the oil and gas separator filter;
Check the leakage of the hose and all pipe joints, and find the leakage point to be eliminated in time;
Check the tightness of the belt;
Check all wire connections and pre-tighten;
Check the AC contactor contacts;
Clean the dust on the surface of the motor suction port and the surface of the housing;
Grease the main motor;
Clean the motor and fan motor.
4. Why the air compressor must be switched regularly
When multiple air compressors are operated in parallel, they must be switched regularly. For air compressors with a humid working environment, switching operations is beneficial for draining the water in the lubricating oil; if the air compressor is out of operation for a long time (such as the middle left for one month), adhesion particles on the oil filter element or the oil and gas separator filter element will occur Drying, clogging the filter holes of the oil filter element or the filter element fiber of the oil and gas separator, shortening the service life of the filter element; the upper part of the air compressor rotor is not soaked with lubricating oil, and the machine is shut down for a long time, causing this part of the rotor to contact with moist air and rust; Time shutdown will also cause oil deposits on the air compressor piping or main engine, which will force the air compressor to be overhauled.
5. What are the maintenance items after the new compressor is put into operation?
After the screw air compressor is put into operation, the maintenance items after 300h ~ 500h: oil change and oil change filter, clean air filter element, check for leakage, looseness, oil storage barrel drainage, clean the mobile body, belt tightness inspection and transmission device inspection , Motor temperature rise, current, host sound check.
Maintenance items after 2000h after the new machine is put into operation: check for leaks and looseness, drain the oil tank, clean the body, differential pressure of the oil and gas separator, clean the radiator, manually check the safety valve (drawing rod), check the tightness of the belt and the transmission, Motor temperature rise, current, host sound check.
Maintenance items every 6 months or 4000h: oil change and oil change filter, air filter element cleaning, oil and gas separator filter element (or pressure difference exceeds 0.08MPa), check for leaks and loosening, oil storage tank drainage, motorized body cleaning, Oil and gas separation pressure difference, radiator cleaning, manual check of safety valve (drawing rod), motor, cooling fan bearing oil change, electrical insulation, contact condition check, motor temperature rise, current, host sound check.
Maintenance items every 12 months or 8000h: oil change and oil change filter, clean air filter element, oil and gas separator filter element (or pressure difference exceeds 0.08MPa), check for leaks and looseness, drain oil tank, clean motor body, Oil and gas separation pressure difference, radiator cleaning, motor, cooling fan bearing lubricating oil change, electrical insulation, contact condition inspection, safety protection device inspection, aging inspection of circulation system, control system, safety valve, pressure gauge to the national regulations production department school Inspection or replacement, pressure controller, solenoid valve, temperature controller, intake valve, transmission device inspection or replacement, electrical main brake inspection, motor temperature rise, current, host sound inspection, safety device reliability .
The above maintenance items should be strictly implemented by users. The maintenance time of different brands of air compressors is different. The most reasonable maintenance time is still based on the user's summary of the operation status of the air compressor.
