Maintenance of oil-free air compressors is a complex and critical task, which requires the comprehensive use of mechanical, electrical, control and other fields of knowledge and technology. This article will introduce some common maintenance methods and precautions for you to help you better maintain oil-free air compressors.
First of all, before the oil air compressor, we need to understand its working principle and structure. The main components of oil-free air compressor include compressor head, cooling system, control system, filter and so on. The working principle is to compress the air through the compressor, then cool down and remove water through the cooling system, and finally remove impurities through the filter, so as to obtain clean compressed air.
In the process of repair, we first need to rule out the possibility of machine failure. Common faults include abnormal pressure, excessive temperature, excessive noise, vibration, and so on. For different faults, we can take the following maintenance methods:
1. Abnormal pressure: If the pressure is too high or too low, first check whether the pressure switch and regulating valve are working normally. If it is an electronic pressure switch, you can solve the problem by checking the power supply and cable connection. If it is a mechanical pressure switch, check whether the pressure switch is stuck or damaged.
2. High temperature: High temperature may be caused by cooling system failure. Check whether the cooling fan is working properly and whether it is blocked or damaged. At the same time, it is also necessary to check whether there is gas leakage in the compressor head, because gas leakage will cause the temperature to rise.
3. Excessive noise: Excessive noise may be caused by insufficient lubricating oil or blocked filter. Check whether the lubricating oil needs to be replaced or added, and clean or replace the filter.
4. Vibration: Vibration is usually caused by loose or unbalanced internal components of the compressor head. Check whether the fastening bolts are loose. If yes, tighten them in time. At the same time, it is also necessary to check whether the crankshaft is balanced and aligned, and whether it needs to be repaired or replaced.
In addition to the above common faults, there are some other problems that may occur, such as electrical faults, control system failures, etc. For these failures, we need to carefully check whether the electrical connection is normal during the maintenance process, such as whether the power cord is loose, and whether the electrical components are damaged.
When maintaining oil-free air compressors, there are also some considerations to keep in mind:
1. Safety: Before any maintenance work, ensure that the air compressor is powered off and vented. At the same time, wear appropriate personal protective equipment, such as gloves and goggles.
2. Pay attention to the maintenance environment: When maintaining oil-free air compressors, ensure that the working environment is clean and dry, and avoid the existence of flammable and explosive items.
3. Use the right tools: Use the appropriate tools and equipment for maintenance to ensure the accuracy of the operation.
4. Make maintenance records: In the maintenance process, timely record the maintenance content, date and materials used, so as to refer to and track up in the future, maintenance of oil-free air compressors requires comprehensive knowledge and technology, and pay attention to stability and details. If you are unsure about the maintenance of oil-free air compressors, it is recommended that you seek the help of technicians to ensure the quality and completeness of the maintenance work.
