In addition to the screw type air compressor and the following types:
piston 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: The scroll air compressor forms multiple compression chambers through the meshing of the fixed scroll and the movable scroll to realize the suction and compression of gas. It has simple structure, small footprint, low noise and long service life, but it needs higher sealing requirements.
Centrifugal air compressor: Centrifugal air compressor is a kind of turbine compressor. It uses the ultra-high-speed rotation of the motor rotor to drive the impeller to drive the gas to rotate at high speed, and interact with the volute to produce high-pressure, large-flow compressed air. This air compressor has compact structure, small size, good sealing, light weight, low vibration, and high efficiency under rated conditions. It is considered to be one of the promising air compression methods in the future.
Reciprocating air compressor: Compresses air into high-pressure gas through reciprocating motion. The air compressor has simple structure and convenient maintenance, and is suitable for small and medium-sized industrial occasions.
In addition, according to different lubrication methods, air compressors can also be divided into oil-free air compressors and oil-free air compressors. According to performance, it can be divided into low noise, frequency conversion, explosion-proof and other types of air compressors. According to the purpose, air compressors are used in refrigeration equipment such as refrigerators and air conditioners, as well as in occasions such as pneumatic tools. According to the form, it can also be divided into fixed, closed and mobile air compressors.
In general, there are many types of air compressors, and which type of air compressor to choose depends on the specific application requirements and working environment.
What oil is added to the air compressor depends mainly on the type of air compressor, the working environment and the manufacturer's recommendation. Generally speaking, the choice of air compressor oil can be considered from the following aspects: 1. oil type Mineral oil (mineral-based oil): Mineral oil is a traditional
Q: Water lubricated oil-free screw air compressor with belt? A: Yes. The "water-lubricated oil-free screw air compressor" produced by Shanghai granklin (group) 7.5 kW two kinds of motor direct connection and belt drive. high power empty
Q: What is the application scenario of the oil air compressor? A: Compressed air can be used for various tools, equipment and machines, such as spray guns, pneumatic tools, pneumatic valves, etc. Purge and clean machines, equipment and parts, compressed gas from air compressors during the manufacturing process.
The shutdown sequence of the air compressor and the cold dryer shall be: close the air compressor first, and then close the cold dryer after the system pressure is released. The specific steps and reasons are as follows: Close the air compressor 1. to the shutdown sequence and steps: Press the air compressor stop button, and the equipment will gradually stop.
The main reason for refueling the air compressor is to ensure the normal operation of the machine and extend its service life. Specifically, the importance of air compressor refueling is reflected in the following aspects: 1. lubrication and reduce wear: there are many high-speed parts inside the air compressor, such
PPM is the abbreviation of "parts per million" (parts per Million), which means that the proportion of a substance in the total amount is one part per million, that is, the target substance contained in each million parts of the mixture. This unit is in the fields of science, engineering, medicine, etc.
The textile industry, a field with high requirements for air quality and stability, is ushering in the innovation of oil-free air compressor technology. The water-lubricated oil-free air compressor produced by Shanghai Granklin Group has become an ideal choice for the textile industry with its unique advantages. Textile machinery in production
The level of compressed air used in food processing is very strict to ensure the safety and hygiene of food. These requirements usually follow relevant international or national standards, such as ISO 8573-1, and cover many aspects, including purity, microbial content, particulate matter
The air compressor power corresponding to the flow rate of 5m/min is not a fixed value that can be given directly, because the power of the air compressor is related to many factors such as type, brand, exhaust pressure, efficiency, etc. However, we can base ourselves on some common scenarios and estimates
Air compressor maintenance cycle due to different manufacturers, models and conditions of use vary. For the water-lubricated oil-free variable frequency screw air compressor of Shanghai Granklin Group, the maintenance period is usually recommended to be determined according to the following factors: manufacturer's recommendations
