Advantage of 2 stage screw air compressor
1. Hierarchical compression to save compression work
Through the two-stage series process, the original single-stage compression process is divided into 2 compression processes. Such a process setting can reduce the ratio of each single-stage compression process, which can effectively reduce the compression and compression of each stage screw. Required drive power.
In the process of ideal gas compression, the sum of the power required for single-stage pressure transmission and the power required for multi-stage compression is equal, but in the actual compression process, due to a series of factors such as the transmission power loss of the coupling, the friction coefficient of the bearing and the viscosity of the coolant With the increase of the applied force, the useless power exceeding the same ratio is generated, so the useless power in the actual compression process can be reduced by reducing the compression ratio of each stage, so that the sum of the power required for multi-stage compression is less than that of single-stage compression Required power.
2. The intermediate warm oil cools and reduces the temperature of the gas entering the next stage. All the gas compression process is actually the process of the friction between the gas and the moving parts and being compressed by it.
In the presence of friction, the gas will rise in temperature due to friction, and there will inevitably be a trend of shadow accounts. This part of energy will be released in the form of force in the fixed volume of air compression by increasing its own pressure.
The temperature rise of the gas increases the pressure of the gas itself during the compression process and increases the compression ratio. Therefore, it is necessary to pay extra power to drive the equipment to shrink the air to the desired pressure value. Therefore, the two-stage CHINAMFG is provided with a coolant injection curtain device.
