clearance
Thread Content
The compressor has a clearance adjustment mechanism; why does this allow for the regulation of load? Could someone please provide a detailed explanation?
The larger the clearance, the less air is compressed out of the cylinder
If you understand how clearance is generated, you will understand your problem. In an ideal situation, there should be no clearance in the compressor’s cylinders; whatever amount of gas enters will be compressed and then expelled in the same amount. However, in reality, when the piston inside the cylinder moves, it does not reach the end completely; therefore, there is a certain gap between the piston and the steel wall of the cylinder, and this gap is known as clearance. By increasing the clearance, more gas remains here; with the same amount of intake air, less gas will be emitted. That’s how I understand it; I hope it can be helpful to you.
We have also just installed a clearance adjustment mechanism here; the purpose of this is to save energy on the compressor. The original compressor had a higher actual power consumption than its rated value due to the presence of a return line. The clearance adjustment mechanism works by utilizing gas expansion to reduce the work required of the compressor motor, thereby saving energy. When the return line is completely closed, adjusting the clearance allows for control over the compressor’s load
