Air compressors have roughly gone through three stages of development in my country
The first stage is the era of piston compressors. Before 1999, the main compressor products in my country's market were piston compressors, and downstream enterprises had insufficient understanding of screw compressors, and the demand was not large. At this stage, foreig...Read more -
Single-Stage Compressor vs Two-Stage Compressor
Let OPPAIR show you how a single-stage compressor works. In fact, the main difference between a single-stage compressor and a two-stage compressor is the difference in their performance. So, if you are wondering what is the difference between these two compressors, then let’s take a look at how i...Read more -
Do you know why the screw air compressor has insufficient displacement and low pressure? OPPAIR will tell you below
There are four common reasons for insufficient displacement and low pressure of screw air compressors: 1. There is no contact between the yin and yang rotors of the screw and between the rotor and the casing during operation, and a certain gap is maintained, so gas leaka...Read more -
Where are air compressors generally used?
As one of the necessary general equipment, air compressors play an irreplaceable role in most factories and projects.So, where are exactly need to use the air compressor, and what role does the air compressor play? Metallurgical industry: Metallurgical industry is divide...Read more -
Introduction of OPPAIR screw air compressor
OPPAIR screw air compressor is a kind of air compressor, there are two kinds of single and double screw. The invention of the twin-screw air compressor is more than ten years later than the single-screw air compressor, and the design of the twin-screw air compressor is m...Read more -
The structure principle of OPPAIR screw air compressor
The OPPAIR screw compressor is a positive displacement gas compression machine with a working volume for rotary motion. The compression of the gas is realized by the change of the volume, and the change of the volume is achieved by the rotary motion of the pair of rotors...Read more -
Compression principle of OPPAIR screw air compressor
1. Inhalation process: Motor drive/internal combustion engine rotor, when the tooth groove space of the main and slave rotors is turned to the opening of the inlet end wall, the space is large, and the outside air is filled with it. When the end face of the inlet side of...Read more -
Why can OPPAIR inverter air compressor achieve energy saving and high efficiency?
What is an inverter air compressor? The variable frequency air compressor, like the fan motor and water pump, saves electricity. According to the load change, the input voltage and frequency can be controlled, which can keep the parameters such as pressure, flow rate, te...Read more -
