Working Principle and Technical Parameters

1. Working principle:

1.1 The compressor is a reciprocating, piston-type compressor with a middle body and cross head design. It utilizes a combination of air cooling and water cooling for efficient operation. The compressor is oil-free and lubricated, ensuring clean and pure compressed oxygen.

1.2 When the compressor is in operation, the motor drives the crankshaft through a v-belt, causing the piston to move back and forth. This movement changes the volume of the cylinder, resulting in a change in gas pressure. The compressor uses a one-way valve, inlet ball valve, exhaust globe valve, cooling water pump, and flow meter for efficient gas compression and delivery.

1.3 The gas in the pressure state is drawn into the cylinder through the inlet valve block, inlet solenoid valve, and inlet pipe. It undergoes three stages of compression, resulting in the desired pressure. The compressed gas is then discharged through the one-way valve, pipeline, and exhaust valve block for use.

1.4 The compressor is equipped with intercoolers between the stages to ensure optimal cooling and efficiency.
