Belt air compressor
When the piston runs down at the highest point, the suction valve Open, the gas enters the cylinder from the suction valve and fills the whole volume between the cylinder and the piston end until the piston runs to the lowest point, and the suction process is completed. When the piston runs upward from the lowest point, the suction valve is closed and the gas is sealed in the sealing space of the cylinder. The piston continues to run upward, forcing the space smaller and smaller, so the gas pressure increases. When the pressure reaches the value required by the work, the compression process is completed. At this time, the exhaust valve is forced to open, and the gas is discharged at this pressure until the piston runs to the highest point, and the exhaust process is completed.
Which is the best centrifugal compressor ? Features of piston compressor:Advantages: 1. No matter the flow is small, it can reach the pressure of the cup, which is like a single stage，The final pressure can reach 0.3 ~ 0 ・ 5MPa, and the final pressure of multistage compression can reach ・ loompao
2. High efficiency. During gas volume adjustment, the exhaust pressure is almost unchanged. Disadvantages: 1. When the speed is low and the exhaust volume is large, the machine appears stupid;The structure is complex, there are many vulnerable parts, and the maintenance quantity is large. 3. Poor dynamic balance and vibration during operation. 4. The exhaust volume is discontinuous and the air flow is uneven.
