Working Principle: Understand the innovative working principle of the Sanzhi Compressor, where cutting-edge technology meets the science of air compression to deliver unparalleled efficiency and power.

In an ideal air compression process, the theoretical power required for single-stage pressure transmission matches the cumulative power needed for multi-stage compression. However, in real-world applications, the actual working power increases due to coupling transmission losses, bearing friction, and the cooling effects of liquid viscosity, among other factors. By strategically reducing the compression ratio at each stage, unnecessary power consumption can be curtailed, enabling multi-stage compression to demand less total power than its single-stage counterpart.

The two-stage screw air compressor is a marvel of engineering, featuring a dual-stage rotary screw design. Each stage comprises an active and a passive screw, with the active screw propelling the passive screw via an external power source. The first stage employs a low-pressure rate screw group, while the second stage utilizes a high-pressure rate group. Encircling each screw is a sealing air film that, during rotation, compresses the gas through a seamless cycle of suction, pressurization, and exhaust, delivering exceptional efficiency.

First stage compression: In this initial phase, the two-stage screw air compressor leverages a low-pressure rate screw group to compress gas. The gas is drawn into the screw compression chamber via the suction valve, and as the screw rotor spins at high speed, the gas is incrementally forced out and transported to the next phase of compression.

Second stage compression: During this advanced phase, the gas enters a constricted screw space within the second-stage screw group, where it is compressed under increased temperature and pressure. The exhaust valve then opens, efficiently extracting the high-pressure gas from the system, completing the compression sequence.

Natural air is first drawn into the compression system via an air filter, where it blends with a minimal quantity of lubricating oil within the compression chamber. This mixture undergoes initial compression to an interstage pressure level. It then moves through a cooling channel, encountering abundant oil mist, which significantly lowers its temperature. The cooled, compressed gas then enters the second-stage rotor, where it undergoes further compression to reach the final exhaust pressure, culminating in a fully optimized compression cycle as the air is released through the exhaust valve.

7) Two-Stage Compression Unique Air End: Our unique two-stage compression screw machine design integrates the first and second-stage compression rotors within a single casing. Driven independently by gears, it optimizes linear speed for each rotor, significantly enhancing compression efficiency.

8) Internal Spray Curtain Cooling Method: Utilizing a high-energy-saving internal spray curtain cooling method, it effectively lowers compressed air temperatures, approaches isothermal compression, reduces pressure loss between stages, and boosts compression efficiency.

9) Reduce Internal Leakage: By adopting two-stage compression, we decrease the compression ratio per stage, minimizing internal leakage from high to low pressure, thus enhancing volume efficiency.

10) Noise Reduction: The two-stage compression effectively lowers the compression ratio, substantially reducing noise levels, particularly during unloading operations, for a quieter working environment.

11) Easy Maintenance and Service: This two-stage compressor unit retains the simplicity of single-stage systems, aside from the screw air end, providing ease of maintenance and use for end-users.
