What Is a 5HP Air Compressor?
An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating pistons, rotating blades or rotating screws. Centrifugal compressors are very large applications.
- There are many types of air compressors (air compressors) [1]
- 1 :: oil circulation system [2]
- The compressor is directly driven by the motor, which causes the crankshaft to rotate, and the connecting rod causes the piston to reciprocate, causing the cylinder volume to change. Due to the pressure change in the cylinder, the air is passed through the air cleaner (muffler) into the cylinder through the intake valve. During the compression stroke, due to the reduction of the volume of the cylinder, the compressed air passes through the exhaust valve and passes through the exhaust pipe. The check valve (check valve) enters the gas storage tank. When the exhaust pressure reaches the rated pressure of 0.7 MPa, it is automatically stopped by the pressure switch. When the pressure of the gas storage tank drops to 0.5--0.6MPa, the pressure switch is automatically connected and started. [2]
- a. Traditional aerodynamics: pneumatic tools, rock drills, pneumatic picks, pneumatic wrenches, pneumatic sandblasting
- b. Instrument control and automation devices, such as tool change in machining centers.
- c. Vehicle braking, doors and windows opening and closing
- d. Use compressed air to blow the weft in the air-jet loom to replace the shuttle

- The market size of China's air compressor industry has been growing at a rate of more than 8%. From 2010 to 2011, the growth rate even exceeded 28%, and the market size has expanded rapidly. However, in such a huge market, foreign companies have controlled most of the market for a long time. According to forward-looking network data, in 2009, China's air compressor industry had a total of nearly 400 production enterprises, of which the number of domestic-funded enterprises was close to 90%, and total sales revenue was about 6 billion yuan, accounting for 40% of the entire industry; 10%, with a total sales revenue of about 9 billion yuan, accounting for 60% of the entire industry [3]
- Air compressor noise control mainly uses three aspects: muffler, muffle tunnel and sound insulation technology [2]
- The air compressor is one of the main mechanical power equipment of many enterprises. It is very necessary to maintain the safe operation of the air compressor. Strict implementation of the air compressor operating rules will not only help extend the life of the air compressor, but also ensure the safety of air compressor operators. Let s take a look at the air compressor operating rules [4]
- 1. Use of compressed air [5]
- I. Scope and conditions of promotion products [6]
