Air compressors are widely used
There are many varieties of air compressors, which can be divided into capacity refrigeration compressors, reciprocating refrigeration compressors and centrifugal compressors according to the principle. Common air compressors contain Lang gas air compressors, air-cooled air compressors, centrifugal compressors, sliding vane air compressors and scroll compressor air compressors.
air compressors, which can be divided into capacity refrigeration compressors, reciprocating refrigeration compressors, and centrifugal compressors according to the principle. Common air compressors include Lang air compressors, air-cooled air compressors, centrifugal compressors, sliding vane air compressors and scroll compressor air compressors.
the most common things we see in the sales market should be Langqi air compressors and air-cooled air compressors. The basic principle is composed of a crankshaft, piston rod, cylinder, etc. When the engine crankshaft rotates, the piston rod moves back and forth according to the crankshaft transmission system, and the working volume composed of the cylinder cavity, cylinder head and piston rod top surface will produce a periodic change. When the piston rod is moved from the cylinder head, the working volume in the cylinder slowly increases. At this time, the vapor body opens the bypass valve along the air inlet port and enters the cylinder until the working volume is large and the bypass valve is closed; When the piston rod moves in the opposite direction, the working volume in the cylinder decreases and the air pressure increases. When the working pressure in the cylinder is slightly higher than the working pressure of the exhaust pipe, the automatic exhaust valve is opened, and the cylinder is discharged until the piston rod is moved to the upper limit, and the automatic exhaust valve is closed. When the piston rod moves in the opposite direction again, the whole process repeatedly. To put it simply, the engine crankshaft rotates for one week, the piston rod reciprocates once, the cylinder is reduced, and the whole process of the exhaust pipe master cylinder is carried out in the working circulation system. However, because of the high noise of the piston air compressor, the screw air compressor slowly replaces too many spare parts.
