Frequently Asked Questions
Two-stage compression reduces the compression ratio of each stage and improves volumetric efficiency. Compared to single-stage, the reduced compression ratio of each stage of a two-stage compressor improves volumetric efficiency and reduces the internal and external leakage of each stage.
For example, single-stage compression screw machine rotor: the pressure at the inlet end is about 1 bar of atmospheric pressure, compressed by the rotor to an outlet pressure of 8 bar, the compression ratio of the compression process is 8/1, that is, the single-stage compressor compression ratio of 8. While the pressure at the inlet end of the dual-stage is about 1 bar of atmospheric pressure, compressed by the first-stage rotor to an outlet pressure of about 3 bar, and then into the second-stage rotor compression to enhance the pressure to the required 8 bar The compression ratio of the first stage low pressure rotor is about 3, and the compression ratio of the second stage high pressure rotor is 8/3 ≈ 2.67, i.e. the compression ratio of the second stage is about 2.67. The maximum compression ratio of the two-stage compression rotor system is about 3.
A two-stage air compressor works by compressing air in two stages. In the first stage, air is compressed to an intermediate pressure and then sent to a second cylinder where it is compressed to the final desired pressure. This allows for higher efficiency and greater power output compared to a single-stage compressor.
First, check the refrigerant pressure and ensure that the cold dryer and suction dryer are working properly. Also, make sure that the air compressor’s storage tank and filters are draining properly. Then, open the valves between the storage tank, dryers, filters, and the air compressor to ensure smooth airflow.
Next, check the oil level and look for any leaks or obstacles around the machine. If it’s a water-cooled machine, open the cooling water valve and pump, and confirm that the water pressure is normal. Finally, turn on the power and start the machine. If it has been idle for a while, start it a few times before running it continuously to avoid unnecessary malfunctions such as overheating or overload.
