The Ins and Outs of Diaphragm Compressor: A Comprehensive Guide

Positive displacement compressors using diaphragms, sometimes referred to as diaphragm compressor, are a dependable and adaptable kind of compressor. They are an invaluable tool in a variety of sectors since they have clear benefits over conventional piston compressors. This thorough book dives into the realm of diaphragm compressors, examining their functions, advantages, and selection criteria.

Understanding Diaphragm Compressors:

A diaphragm compressor flexible membrane serves as the piston at its core. This membrane reciprocates back and forth inside a sealed container under the power of a crank mechanism. The chamber volume rises as the diaphragm descends, allowing gas to enter through an intake valve. On the other hand, when the diaphragm moves higher, the chamber volume lowers, compressing the gas and pushing it out of an output valve.

By doing away with the necessity for lubrication inside the compression chamber, this oil-free design keeps the processed gas clean. Because of its reputation for clean operation, diaphragm compressors are perfect for applications requiring clean air or delicate materials.

Working Principles: A Deeper Look:

A reciprocating diaphragm and several valves form the basis of the straightforward yet efficient concept that drives these compressors. A closer examination of the crucial phases in a single compression cycle is provided below:

  • Intake Stroke (Suction):

By forcing the flexible diaphragm lower, the crank mechanism increases the sealed chamber’s capacity. This causes a region of low pressure to form inside the chamber. Consequently, the inlet valve is forced to open due to the pressure differential between the chamber and its surroundings. As the expanding chamber is filled with fresh gas, the pressure differential is satisfied.

  • Recognize in Compression Stroke:

The diaphragm is forced higher as the crank rotates more. In doing so, the chamber capacity decreases and the trapped gas within is compressed. Because of the constant gas amount and decreasing volume, the pressure within the chamber builds gradually.

  • Discharge Stroke (Delivery):

The exit valve is pushed open when the pressure inside the chamber surpasses the discharge pressure set by a predefined amount. Through the open outlet valve, the compressed gas exits the chamber at a pressure greater than that of the surrounding air.

  • Cycle Completion:

The compressed gas is released and the chamber volume is reduced when the diaphragm reaches its highest position. After that, the crank mechanism turns around, putting the diaphragm back in its initial position. Because the pressure within the chamber is higher than the outside air, the inlet valve closes. When the pressure within the chamber drops below the discharge pressure level, the exit valve likewise closes. This concludes a whole cycle, and the procedure is then repeated endlessly.

Key Points:

Within the chamber, there are alternating zones of high and low pressure due to the diaphragm’s reciprocating action.

  • The gas flow via the inlet and outflow valves is controlled by the pressure differential between the chamber and its surroundings.
  • The point at which compressed gas is released from the chamber depends on the preset discharge pressure level.
  • As long as the compressor is functioning, this cycle will continue to produce compressed gas at the appropriate pressure continuously.
