1. oil free air compressor current is too high:
the common causes of this failure are mainly the following:
1. The host fails
2. Exhaust pressure is too high
3. The voltage is too low: Generally, the power of the oil-free air compressor is rated. Therefore, according to the formula, if the voltage is too low, the current will definitely be too high. This is well understood.
2. oil-free air compressor keeps working, but the gas supply is still insufficient:
common causes of this failure are:
1. Air leakage: The judgment method is to listen to the external pipes of the air compressor, the air supply pipe of the air compressor on the air storage tank, the one-way valve, safety valve, pressure switch and other joints for air leakage. If so, it must be handled.
2. Wear of the head leather bowl: The service life of the general leather bowl is about 3 years, and it must be replaced after the expiration date.
3. Exceeding the rated flow
4, the machine overload work
3. oil-free air compressor works intermittently and the air supply is insufficient:
the causes of this failure are:
1. Start capacitor leakage. When leakage occurs, the compressor head can still be started, but the speed is slow and the current is large. Due to the large current, the head heats up quickly, and the head will be protected and shut down soon. This problem can be changed to a new one, but it should be noted that UF numbers should be the same, too large or too small is not good.
2. Insufficient voltage. There is a buzzing sound at the start. If the operating current is too large at this time. Oil-free air compressor head working minimum voltage of 200V, below this voltage head is difficult to start, frequent start will cause the head temperature rise. Final circuit protection shutdown. Until the temperature drops and turns on again. For areas with frequent voltage fluctuations, it is recommended to install an automatic voltage regulator.
4. oil-free air compressor can work, but the noise is obviously larger than the original:
the causes of this failure are:
1. The air compressor fixing device or accessories are loose
2. Abnormal operating current
3. The motor bearing is seriously worn
4. The cup is damaged
the 5. air compressor must put the air pressure of the air storage tank to zero air pressure before starting work every time it works, otherwise it cannot be started. When the machine is powered on, you can see that the machine head turns very slowly, there is a buzzing sound, and the current is also large:
the cause of this kind of failure is probably that the one-way valve is blocked. The one-way valve of the oil-free air compressor is installed between the air compressor outlet pipe and the gas storage tank. The main function is to allow the gas from the machine head to only enter the gas tank. The gas from the gas tank cannot come out. Inside is a spring and a film. If dirt sticks to the film, it will cause reverse air leakage, then the second start of the machine head will be pressed by high pressure and unable to start. The solution is to use a plate to open the valve cover behind the one-way valve, please wash it and put it back as it is.
Why do you need to change the air compressor oil regularly? 1. Mechanical oil is an aromatic hydrocarbon synthesized by chemical industry, and when the air compressor running at high pressure and high temperature is running back and forth, it will continue to decompose small molecules of cyclic hydrocarbons.
As a common equipment in the industrial field, the noise level of the permanent magnet screw air compressor is one of the focuses of the user's attention. Generally speaking, the noise level of permanent magnet screw air compressor is between 65 decibels and 85 decibels, which is suitable for most industrial applications. Specifically.
The difference between oil-free air compressor and oil-free air compressor is: different materials, different final discharge of gas, and different life. Different 1. materials: 1. Oil-free air compressor: the material of oil-free air compressor contains oily substances, which will pollute the terminal equipment; 2. Oil-free air compressor: the material of oil-free air compressor does not contain oily substances, thus avoiding the pollution of oil-free air compressor to terminal equipment.
How to properly maintain and maintain oil-free air compressor 1, oil-free air compressor intake air filter element maintenance and maintenance. The air filter is a component that filters out air dust and dirt, and the filtered clean air enters the compression cavity of the screw rotor for compression. Because of the screw machine
Food companies should consider the impact of various potential risks, if the use of 100 oil-free compressor, can minimize the potential risk of compressed air from the air compressor, to provide protection for enterprise production. Finally, food companies must ensure that compressed air systems are safe for the health of consumers. Consumers pay great attention to the safety of the purchased food, so in the production process, all operations with the air compression system should be recorded to avoid unnecessary trouble!
Granklin Group is a manufacturer specializing in the production of water-lubricated air compressors. The water-lubricated air compressors we sell are very suitable for medical equipment and hospital oxygen supply. Water lubricated oil-free air compressors are often used in hospitals, laboratories and other industries where the environment is quiet and the quality of the gas source is high.
View detailsWhen purchasing water lubricated air compressors, the factory often asks about 75kW air compressors. After the sales manager Shen of Shanghai granklin group air compressor company learned about it, it turned out that this enterprise was used to produce food. because food safety was very important, our sales manager chose the new water for our customers.
If the condensed water of the air compressor is not discharged for a long time, the inside of the unit will rust and the lubricating oil effect will be reduced, which will affect the operation of the air compressor. In summer, the air compressor can also stop and start continuously. What is the basic principle? Air compressor condensate
Air compressor is one of the indispensable gas equipment in the production activities of enterprises, which plays a boosting role in the production process. When selecting screw air compressors, we all want to choose brand and good quality machines, so which air compressor is a good product
In some industries, the more widely used models are power frequency units. This type of unit is composed of a pair of male and female rotors meshing in parallel with each other to rotate in the cylinder, so that the air between the rotor cogging continuously produces periodic The volume changes, the gas will follow the rotor shaft
