Two stage screw compressor: function comparison between two-stage screw compressor and piston air compressor

　　

Piston air compressor and two-stage screw compressor are often seen in machinery. This time, comps compressor will introduce and compare their different characteristics.

The piston air compressor has many vulnerable parts, such as air valve, piston, piston ring, connecting rod bush, etc. the reliability of continuous operation is poor, which will affect production on the one hand, and increase the cost of maintenance and management on the other hand.

Compared with screw air compressor, piston air compressor has low efficiency, especially for long-term continuous operation, and its economy is not strong. As many of the compression chambers formed by the piston air compressor are vulnerable parts, the wear and damage of these vulnerable parts will cause greater leakage during gas compression, which will greatly reduce the efficiency. There are no wearing parts that affect the efficiency of the machine in the screw compressor. A pair of rotors for compression are not in direct contact and will not be worn. Therefore, the economy of long-term continuous operation is much better than that of piston air compressor.

The screw machine is more stable and has good protection, but the maintenance cost is also high. It is suitable for occasions with relatively large gas consumption or high power in popular terms. The piston machine is good at moving easily, with small gas consumption and low gas quality requirements, but it should be flexible and cost less. Generally, 11kw is large. It has the characteristics of low maintenance cost and low purchase cost, but its relative life is short.
