The basic concept of air compressor:
the air compressor is a pressure generating device that converts mechanical energy into gas pressure energy.
use of air compressor:
air compressor is a kind of gas power source conversion equipment, which is used in all aspects of life. In the construction, iron and steel, mining and chemical industrial plants in many uses, especially the twin-screw air compressor is widely used in machinery, metallurgy, electronic power, medicine, packaging, chemical, food, mining, textile, transportation and many other industrial fields, and become the mainstream of compressed air products.
air compressor classification and working principle
there are many types of air compressor, common screw air compressor and piston air compressor
the piston air compressor uses an electric motor or diesel engine to drive the pulley to directly drive the crankshaft through the coupling, drive the connecting rod and the piston rod, and make the piston reciprocate in the cylinder to complete the suction, compression and discharge process.
When the reciprocating piston in the cylinder moves up and down, the pressure in the left cavity of the piston in the cylinder is lower than the normal atmospheric pressure, the suction valve opens, and the outside air flows into the cylinder. This process is called the compression process. When the pressure in the cylinder is higher than the air pressure in the gas pipeline, the exhaust valve opens and compressed air is delivered into the exhaust pipeline. This process is called the exhaust process.
Single-cylinder piston ▼ Double-cylinder piston ▼ Next, the pressure-free or low-pressure gas is boosted and delivered to the gas tank. When the pressure in the gas tank reaches a certain value, the piston air compressor does not stop running but opens the safety valve. No compression operation. Another way is that when the pressure in the gas tank reaches a certain value, the compressor will automatically stop working.
Screw air compressor
it is composed of a group of two parallel screws that bite each other. When the motor drives the two screws to rotate, because the gap between the two screws and the shell is only about 10 wires, the main screw drives the auxiliary screw to rotate together, and the outside air passes through the screw teeth. It is sucked in. As the volume between the teeth of the spiral rotor rotates, the volume between the teeth decreases continuously with the bite of the rotor teeth, and the compressed pressure of the gas increases, when the rotor turns to the same pressure between the teeth and the exhaust hole, the compressed air starts to be discharged.
Nanning screw air compressor accessories, Nanning screw air compressor where to buy some manufacturers still marked on the parts. Generator and other important components. The oil filter, oil separation device, etc. are also accompanied by an operation manual. Certificates and introspections. Pointing user is
All the time, is the quotation of high air compressor? Then how to effectively reduce the maintenance cost of air compressor? 1. Ensure the quality of equipment parts The quality of equipment parts can also determine the quality of air compressor, and can improve the performance of equipment.
Need to purchase air compressors for food production, you can choose our Shanghai Granklin Group. Granklin Group is specialized in the production of water-lubricated screw air compressors. We have a number of project cases for reference and field visits. Food Line
The main features of the water lubricated screw air compressor are: reasonable structure, ideal force balance; no radial and axial force during operation, only rotational force. Single-stage compression ratio is high, the shape of the structure size is small: high speed light load, easy to establish hydrodynamic lubrication.
Textile processing and production process, including proofing, marking, cutting, sewing and other processes, many of which need to use compressed air. Granklin oil-free air compressors have been in the textile industry for many years, helping to provide high-quality textile products, including high-pressure series air compressors.
Oil-free compressor test machine parameters, screw air compressor test contains what are the main parameters? Especially in the sale of air compressor manufacturers will test the parameters.
View detailsIn recent years, the biggest black horse in the screw air compressor market (water lubricated screw air compressor) is a new type of air compressor equipment. Whether it is working principle or lubrication method, it is quite different from the traditional screw air compressor. shanghai granklin group for your detailed introduction under the oil and water lubrication screw air compressor working principle and advantages.
View detailsChina is rich in coalbed methane resources. Accelerating the development of coalbed methane can not only alleviate the contradiction of natural gas shortage, but also ensure the safety of coal mines and reduce air pollution. Choosing air compressor for coalbed methane project, the better choice is to choose the current market
Air compressors are generally classified into the following categories: 1. According to the gas transmission volume, to put it bluntly, the gas transmission volume refers to the volume of the gas discharged from each minute of the air compressor during operation, calculated to be sucked in. The small and medium-sized exhaust volume is less than 10 cubic meters/minute, and the small and medium-sized exhaust volume is 10~100 cubic meters
In the process of air compressor maintenance, one of the most common faults is the overload of the motor of the air compressor.
