Q: What is the difference between power frequency and permanent magnet frequency conversion?
Answer: The motor of the power frequency air compressor runs at a fixed speed and full load every time it starts. The motor of the permanent magnet variable frequency air compressor has less impact on the power grid. It gradually increases the speed to reach the gas pressure and maintains the stable output of the pressure. When the power frequency air compressor reaches the pressure value, it will stop and wait for the next start.
Shanghai Granklin Group produces screw air compressors, including "water-lubricated power frequency air compressors" and "water-lubricated permanent magnet frequency conversion air compressors", and the water-lubricated series of screw air compressors we produce are oil-free.
The oil content standard of general air compressor varies according to the type and application scenario: general air compressor: the national standard stipulates that the liquid oil content in compressed air shall not exceed 5 mg/m & sup3;, and the oil vapor content shall not exceed 0.5 mg/m & sup3;. This standard is designed to ensure that compression
In addition to the screw type, there are several types of air compressors: Piston type air compressor: This is an earlier type of air compressor that compresses gas through the reciprocating movement of the piston in the cylinder. Scroll air compressor: scroll air compressor through the fixed scroll
Q: What are the risks of compressing flammable and explosive gases? Answer: Ordinary air compressors cannot compress flammable and explosive gases, such as gas. Shanghai Granklin Group reminds you that the screw air compressor that compresses flammable and explosive gases needs to be explosion-proof,
Breaking, punching, piling and other operations. The use of mobile air compressor can provide high-quality compressed air, improve work efficiency, reduce working time and cost. Mining, water conservancy, transportation, shipbuilding, urban construction, energy, military and other industries: these industries are often
Medium pressure screw air compressors usually have good performance and a wide range of application scenarios. The following is about the specific evaluation of the medium pressure screw air compressor and the water lubricated medium pressure air compressor of Shanghai granklin group: the efficiency and performance of the medium pressure screw air compressor:
Frequency conversion screw air compressor has been widely used in many industrial occasions because of its high efficiency, energy saving and intelligent characteristics. The following are some specific applications: 1. industrial production field Automobile manufacturing: In the automobile manufacturing process, the frequency conversion screw air compressor
If there is a large number of air blowing and cooling processes in your processing, the air consumption will be obviously too large. It is suggested to directly match the air volume according to 8 cubic meters per minute or even higher. It is better to match the air pressure instead of being too small, so as not to report to the police and stop the machine when working, which will affect the production.
1. After using it every day, it is necessary to check the oil level, exhaust temperature, exhaust pressure and other aspects of the screw air compressor to see if there is any abnormal situation. If the oil level is too low, it is necessary to add lubricating oil in time. In addition, there is a need
The solution to the excessive water output of the air compressor 1. the core reason for the excessive water output. During the operation of the air compressor, the temperature rises when the air is compressed, and the water vapor in it will condense into liquid water with the decrease of temperature. If there is too much water, it is usually caused by the following reasons: ring
The shortcomings of the permanent magnet variable frequency air compressor mainly include the following: Oil problem: For the oil-injected permanent magnet variable frequency air compressor, the compressed air contains oil, which may not be applicable in specific industries such as the food industry, because Oil may pollute the product.
