Two Stages PM Compressor 220HP 33.0-22.5M3/min
Details Of Two Stage Screw Air Compressor
Two Stage PM Air Compressors are extensively applied to
pharmaceutical, textile, instruments, electronics, machinery,
printing, chemicals, mining and transportationindustries. Using
two-stage compressor is to use two groups of SKY helical rotors of
different sizes to achieve a reasonable pressure distribution and
reduce the compression ratio of each compression. Low compression
ratio has two special advantages: one is to reduce internal leakage
and improve volume efficiency; the other is to greatly reduce the
load of bearings, improve the life of bearings and extend the life
of the main engine.

Advantage Of Two 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 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.
