Discussion on the Structure Form of the Ultimate Fusheng Air Compressor
The ultimate Fusheng air compressor structure form has been studied for hundreds of years in the generation and use of air compressors. With the improvement of compressor technology and thermal dynamics theory, the best structural form of the compressor - the so-called The ultimate compressor has a clear understanding, this is zero leakage + isothermal compression.
Leakage is the main cause of the decrease in compressor efficiency. While the compressor raises the gas pressure, a part of the gas flows backward through the internal gap of the machine from the high pressure side to the low pressure side. This part of the gas can be called the internal leakage gas, and the flow rate depends on The length and width of the internal gap of the machine. The effect of internal leakage gas on the compressor: 1. Consumes a certain amount of compression work, resulting in a decrease in the energy efficiency of the compressor; 2. Heating the intake air flow, causing the exhaust gas temperature to increase; 3. The airflow passing through the gap produces a "whistling" sound. Increase compressor noise.
The main means to reduce internal leakage are: 1. Design the compressor to give priority to the structure of the compressor with the shortest gap length; 2. Improve the processing and assembly accuracy, and reduce the gap width; 3. Fill the part of the gap by spraying into the cylinder. Improve the sealing effect.
Isothermal compression is an ideal compression process. It is the compression process with the least power consumption. It is the highest technical level pursued by compressor designers. The isothermal compression is characterized by no temperature rise in the compression process and the exhaust temperature is equal to the intake air temperature. Since the air contains a certain amount of water vapor, if the air pressure rises and the temperature rises lagging, the compressed air may reach the pressure dew point, and the water vapor phase changes to form condensed water, which is precipitated from the air. For liquid jet compressors, the injected liquid mixes with the condensate. For injection compressors, excessive condensate will accelerate the failure of the lubricant. Moisture can also cause rusting of metal parts and accelerate machine wear. But spray is the best means of achieving isothermal compression, or even the only means. The water jet compressor is not adversely affected by the condensed water, so the water jet compressor is the ideal model for isothermal compression.
