Common faults and solutions of oil-free air compressors can be summarized as follows:
current too high
possible causes: host failure, exhaust pressure is too high, voltage is too low.
Solution: Check whether the host is operating normally, adjust the exhaust pressure to the normal range, and ensure the stability of the power supply voltage.
Insufficient gas supply
air leakage: check all external pipes, gas storage tanks, check valves, etc. for air leakage, and repair or replace them in time.
Head cup wear: The service life of the cup is generally about 3 years and needs to be replaced regularly.
Exceeding the rated flow: adjust the usage to ensure that the rated flow of the air compressor is not exceeded.
Machine overload work: reasonable arrangement of the working time of the air compressor to avoid long-term overload operation.
Intermittent operation and insufficient air supply
starting capacitor leakage: replace the new starting capacitor, note that the UF number should be the same.
Insufficient voltage: In areas with frequent voltage fluctuations, it is recommended to install an automatic voltage stabilizer to ensure voltage stability.
Noise increases significantly
air compressor fixing device or accessories loose: check and tighten loose parts.
The operating current is abnormal: check the current condition to ensure that the current is stable and meets the regulations.
The motor bearing is severely worn: replace the worn motor bearing.
Broken cups: Replace damaged cups.
Before each work, the air pressure of the air tank must be reduced to zero to start.
Check valve blockage: remove the check valve after the valve cover to clean and reinstall to ensure that it is unobstructed.
In addition, for oil-free air compressors, it is also necessary to pay attention to regular maintenance and maintenance, including cleaning dust, checking whether fasteners are loose, and replacing aging seals. At the same time, the operator should be familiar with the operating instructions of the air compressor and follow the correct operating procedures to ensure the safe and efficient operation of the air compressor.
Please note that the above solutions are for reference only. In actual operation, if you encounter difficulties or are not sure how to deal with the fault, please contact professional maintenance personnel or equipment manufacturers for technical support and maintenance services.
The quality standard of medical compressed air is usually stipulated by the national health department or industry standard. In China, the standard of medical compressed air is regulated by the "Hospital Compressed Air Quality Standard" (GB/T 14213-2013). In addition, medical compressed air should also be
The air pressure of an industrial gas station is not a fixed value, but is determined according to specific application requirements and equipment specifications. Generally speaking, the pressure range of industrial gas source is quite wide, but the common working pressure range is between 0.6MPa and 1.0MPa (equivalent
The pressure of industrial compressed air is a little complicated! But it doesn't matter, I will try to explain it to you simply. Did you know that the pressure of industrial compressed air does not have a fixed value, it is like a fickle small
In the field of highly precise semiconductor testing, compressed air is not only an important power source for the operation of the production line, but also a key factor to ensure test accuracy and product yield. For the semiconductor tester, the quality, dryness, cleanliness and pressure of the compressed air
It is possible to use fuel injection air compressors and filters in food companies, but the following key factors need to be considered: Air quality requirements: The food industry has extremely high requirements for air quality, because any pollution may affect the quality and safety of food. Injection air pressure
The quality requirements of compressed air in the biopharmaceutical industry and the solution of granklin air compressor The biopharmaceutical industry has extremely strict quality requirements for compressed air, and its standards are directly related to the safety, effectiveness and compliance of pharmaceutical production. granklin air compression
The replacement cycle of the lubricating oil of the new screw air compressor is affected by the type of lubricating oil, the working environment and the frequency of use. The following is a detailed guide: 1. the first oil change cycle, the running-in period of the new machine: it is recommended to replace the first lubricating oil after 500 hours of operation to remove the initial oil.
Air compressor itself is not necessarily explosion-proof, but according to its design and application environment to determine whether the need for explosion-proof function. In some specific explosive, flammable gas environment, the use of explosion-proof air compressor is essential to prevent air compressor inside or around
Compressed air buffer tank belongs to special equipment. Definition of special equipment: According to publicly released information, special equipment refers to equipment that involves life safety and is more dangerous, including boilers, pressure vessels, pressure pipes, etc. During the use of these devices
The working pressure range of air compressors is very wide, which mainly depends on its specific application scenarios and needs. The following is a detailed explanation of the working pressure of the air compressor: 1. working pressure range Low pressure air compressor: The working pressure is usually between 0.41.2MPa (MPa),
