The compressors are working machines and as such, require proper care and maintenance to ensure smooth operation and to extend their useful life.
Due to their characteristics, these types of machines require specific Fluid-Aire Dynamics conditions that allow them to perform correctly and therefore help to care and preserve them. So how do you maintain a compressor?
Regardless of their model or design, compressors must receive periodic maintenance, according to the number of hours of work performed by the equipment. For this, it is recommended to keep a record of the machine’s working time.
Before starting maintenance work, the compressor must be switched off using the “ON/OFF” switch. The appliance must then be disconnected from the electrical source and left completely without pressure.
Cleaning The Compressor
Keeping the external components, and especially the internal ones, free of dirt and dust, is one of the most relevant actions in the compressor maintenance process. Cleaning must be carried out weekly since the accumulation of impurities is frequent due to the absorption of air by the compressor.
Excessive accumulation of these external materials can impair the operation of the equipment, causing it to clog and can even hide minor oil leaks. During the cleaning process, dirt must also be removed from the coils and winding fins.
The compressor’s working driven belts must be inspected to check the tension of the belt. Belt tension varies between compressors, but the proper tension value must be maintained, per manufacturer’s specifications.
A loose or slack drive belt will begin to slip and lose its efficiency. If the belt is too tight, it will considerably reduce its useful life, as well as the useful life of the bearings associated with the compressor.
Another aspect to check is the electrical connections of the compressor. Taking the time to verify each connection, and ensure that all of them are properly adjusted is a highly recommended practice. An improperly adjusted electrical connection can permanently damage the electric motor.
The non-return valve must be cleaned once a year, or if required, it must be replaced. The condition of the valve’s rubber disc must be taken into account; if it is very worn, then it is time to change said part. If it is not possible to clean the seat of the rubber disk, the complete non-return valve must be replaced.
All these actions of care and maintenance of the compressor will not only lengthen its useful life, but they will also ensure its operation and the performance of a good job. Of course, they also have a positive influence on the user’s economy by avoiding medium or major damage to the equipment.
