Oil-free air compressor is not gas may have the following reasons:
blocked or damaged intake valve: If there is a problem with the intake valve, the compressor will not be able to suck in air, which will cause the air to be unable to compress. At this time, it is necessary to check whether there is a problem with the intake valve, and clean or replace it in time.
Exhaust filter blockage: The function of the exhaust filter is to filter pollutants in the compressed air. If the exhaust filter is clogged, it will prevent the compressor from discharging compressed air. Therefore, regular cleaning or replacement of the exhaust filter is the key to ensure its smooth flow.
Air filter clogging: long time not clean or replace the air filter will cause the air inlet resistance to increase, so that the pressure is insufficient, can not meet the normal pressure requirements. At this time, the filter element needs to be cleaned or replaced to restore air flow.
Compression screw damage: For oil-free screw air compressors, if the compression screw is damaged or worn, the air cannot be compressed to sufficient pressure. In this case, the compression screw needs to be replaced with a new one.
Motor or circuit failure: The abnormal motor or circuit failure of the oil-free air compressor will also cause the equipment to fail to work normally, thereby affecting the compression and discharge of gas.
PLC failure or solenoid valve problem: If the PLC fails or the solenoid valve (including its circuit, valve body and pipeline) has a problem, it may cause the air intake machine to not operate, thereby affecting the air compressor.
Small pressure check valve failure: When the small pressure check valve fails, even if the pressure in the machine is high, there may be no pressure output, which is also a possible cause of not getting gas.
In order to solve the problem that the oil-free air compressor does not breathe, it is recommended to check the above-mentioned components first, find out the fault point, and repair or replace it in time. If the problem cannot be solved by itself, it is recommended to contact professional air compressor maintenance personnel or the technical support team of the equipment manufacturer for further inspection and maintenance.
Oil-free air compressor is widely used in many occasions because of its unique characteristics and advantages. The following are some of the main applications of oil-free air compressors: University laboratories: pure, oil-free compressed air is often used in the laboratory to ensure the experimental results
In the production process, the division of pressure ranges is usually based on specific industry standards or engineering practices. For 2.5 atmospheres (or 2.5MPa, because 1 atmosphere is approximately equal to 0.1MPa), we can refer to the pressure classification standard of industrial pipelines to evaluate the pressure to which they belong.
In the foundry industry, air compressors are widely used in various technological processes to power casting equipment or to generate compressed air to complete specific tasks. The following are some specific applications of air compressors in the foundry industry: Pneumatic tools and equipment: foundries often make
There are significant differences between screw compressors and scroll compressors in many aspects, which are mainly reflected in the structure, working principle, performance characteristics and application scenarios. Structural contrast screw compressor: mainly composed of a pair of intermeshing male and female rotors (screw), which
Water-lubricated oil-free air compressors and traditional air compressors have their own advantages and disadvantages. The specific choice depends on actual needs and scenarios. The advantages of water-lubricated oil-free air compressors include: oil-free pollution: because lubricating oil is not used, the quality of compressed air is avoided by lubricating oil
As an important equipment in industrial production, the energy efficiency of air compressor is affected by many factors. The following is a detailed analysis of the main factors affecting the energy efficiency of air compressors: compressor design and type: The design specifications and types of air compressors have a direct impact on their energy efficiency.
Air compressor plays a vital role in the production of lithium batteries, and its role is mainly reflected in the following aspects: 1. provide clean and stable compressed air. The production of lithium batteries has extremely strict control of process parameters, of which gas pressure is a Vital finger
Air compressor power frequency and frequency conversion: which is better? In the field of air compressor, power frequency and frequency conversion are two common motor drive methods. They have their own advantages, and the choice of which is better depends on the specific gas demand and working environment. Power frequency air compressor adopts traditional
The maintenance cycle of oil-free air compressors usually depends on multiple factors, including frequency of use, operating environment, machine quality, etc. Generally speaking, the recommended maintenance cycle is as follows: Daily inspection: A simple daily inspection should be carried out before and after each use, including checking the empty
