Comparison between water lubricated oil-free screw air compressor and screw dry oil-free:

1. The exhaust temperature of the water lubricated oil-free screw air compressor does not exceed 50 ℃, and the compression efficiency is almost isothermal; The exhaust temperature of the screw dry oil-free air compressor is about 250 ℃, and the exhaust efficiency is low.

2. The noise of water lubricated oil-free screw air compressor is more than 10 decibels lower than that of screw dry oil-free air compressor.

3. The final exhaust quality of the water lubricated oil-free screw air compressor is the cleanest. During the compression process of the water lubricated oil-free screw air compressor, the air is rinsed with lubricating water to remove any turbidity in the air, which is then discharged through a water filter.

4. Water lubricated oil-free screw air compressor directly sprays pure water into the cylinder. Due to the high specific heat value of water, the gas is almost compressed isothermally in the cylinder. Isothermal compression is the most ideal and energy-efficient compression process in the gas compression process.

5. The water lubricated screw air compressor uses water lubrication to achieve the goal of compressing gas without oil. The fundamental reason why lubrication can be achieved through water comes from its structural advantage: although it is also driven by a worm wheel, this pair of friction pairs does not transmit torque, so the contact stress on the friction pair is very small. The superiority of water lubrication is fully demonstrated when the worm gear and casing are made of special copper alloy that reduces wear and corrosion.

Working principle and characteristics of screw air compressor

1、 Well structured

The two star wheels of the screw air compressor are symmetrically located on both sides of the screw, which not only eliminates unbalanced inertial forces, but also cancels out the axial and radial forces acting on the screw. This is the most significant feature of advanced screw compressor design!

2、 High efficiency

The specific heat of water is high, and the working process is similar to isothermal compression. Screw air compressors theoretically do not have clearance volume. When the screw speed is around 3000r/min, the dynamic lubrication performance is excellent, which determines that the screw compressor has high working efficiency.

3、 Low noise

The meshing pair of the screw air compressor is made of polymer material for the star wheel, and the motor is directly connected to the screw without a main transmission gear. At the same time, the box plate is pasted with sound-absorbing material, so the operating noise is extremely low.

4、 Small vibration

Screw air compressors have superior power balance systems that effectively control the power source, ensuring extremely balanced machine operation without any special requirements for the foundation.

5、 Zero emissions

Only lubricating water similar to drinking water standards is used in the machine to participate in the cooling, sealing, and lubrication functions during the compression process. The machine operates without any emissions of "three wastes".

6、 Can be monitored

With intelligent monitoring as the core concept, achieve comprehensive and scientific traceability management. Real time monitoring of compressors, prevention of accidents, timely reporting of faults on designated computers, and sending text messages to designated management personnel's mobile phones are of great help in preventing production accidents!
