Two Stage PM Compressor 380HP
The two-stage permanent magnet variable frequency air compressor is a compression process, entering the first stage of compression, and then entering the second stage of compression. At the same power, the gas output of the first stage of compression is up to 15%, and the energy saving effect can reach 20-50%.

Advantage of Two Stage PM Compressor
1. Hierarchical compression to save compression work
Through the two-stage series process, the original single-stage
compression process is divided into two 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 screw compressor is provided with a coolant injection curtain device.
