For air compressor users, the failure of air compressor equipment occurs from time to time, but how to avoid or find the failure of the air compressor in a timely and effective manner, so as to prevent and reduce the production accidents and cost losses caused by the air compressor? We should use the following factors for prevention and reference:
1. Environmental and equipment factors, early placement and installation of the air compressor room or site.
When installing air compressor equipment, it is necessary to pre-design the location of common equipment such as air compressor, air storage tank, desiccant, filter, etc., and reserve sufficient heat dissipation space and space between equipment and equipment and between equipment and wall. Overhaul space. The air compressor station should maintain good ventilation and install exhaust fans when necessary. If the air compressor station is built outdoors, it needs to be dustproof, waterproof, antifreeze, and explosion-proof to avoid abnormal damage to the air compressor due to dust, moisture, and extreme high and low temperatures. In addition, it is best to reserve an area for air compressor maintenance and repair in the air compressor station, and the area required for the largest air compressor maintenance in the air compressor station shall prevail to ensure timely and convenient maintenance in the event of an air compressor failure.
2. The air compressor must be maintained regularly in accordance with the law.
Air compressor equipment needs to develop a good habit of regular inspection and maintenance, and form maintenance and inspection records. The inspection scope includes the leakage of compressed air and air compressor grease, regular replacement of lubricating grease and other wearing parts as required, regular inspection of the voltage and current of the air compressor station, and the surface cleaning and cleaning of air compressors and other equipment. Environmental clean-up work, etc. Detailed inspection and maintenance can be carried out with reference to the equipment maintenance manual.
3. Choose suitable accessories when repairing and maintaining.
Air compressor accessories include air filters, oil-water separators and other common wearing parts, as well as air compressor oil required for key equipment lubrication.
Regarding the selection of air compressor oil, the following suggestions are given:
1. Choose the right viscosity and the compressor oil with good viscosity-temperature performance
The choice of compressor oil viscosity is based on the ability to balance lubricity and fluidity. If the working condition of the air compressor has no special circumstances, the user can make a selection referring to the equipment manual; if the working condition of the air compressor is relatively special, it needs to be adjusted appropriately according to the actual working condition. For example, if the working temperature of an air compressor station is relatively high, you need to consider the influence of temperature on the viscosity, and increase the viscosity appropriately; if the air compressor station is outdoors and the temperature difference between day and night is relatively large, you need to choose air compressor oil with better viscosity-temperature performance, etc. .
2. Choose compressor oil with good thermal oxidation stability
For air compressors, due to the compressed gas, 20% oxygen content is really a big test for the anti-oxidation performance of the compressor oil. Good thermal oxidation stability can not only prolong the service life of compressor oil, but more importantly, it can reduce the deposition and accumulation of sludge, paint film and other substances caused by high temperature oxidation, which all cause high temperature of the compressor and affect the normal operation of the compressor Very important factor. In addition, the acidic substances generated by oxidation also have an adverse effect on the metal parts in the compressor to a certain extent.
3. Choose compressor oil with good air separation performance
The control of air release and foam will affect the lubricity of the compressor, and affect the oil and gas separation effect of the compressor, and to a certain extent also affect the service life of the oil and gas separator. In addition, if the oil and gas separation effect is not good, the oil content in the compressed air will be too high, which will affect the subsequent production and product quality.
4. Consider the water resistance of compressor oil
Especially for coastal areas, outdoor air compressor stations and other conditions where the air humidity is high, the moisture content in the air is high, and the presence of condensed water will easily cause the emulsification of the compressor oil, which will affect the performance of the compressor oil, so it is necessary to choose water resistance Compressor oil with good capacity.
5. Do a good job in oil detection and tracking
If conditions permit, regular oil testing is necessary for users. Through regular sampling to detect changes in compressor oil performance, potential compressor problems and failures can be discovered in time through performance changes, and users can be given more accurate oil change instructions to avoid oil waste.
