Different control methods for compressor unloaders

The principle behind these two modes is the same; it’s just that the approach to setting up the adjustment mechanism differs. The approach that should be adopted now is \"no air supply during startup, air supply during operation\"; that is, before the compressor starts, the air volume control mechanism supplies air to push the intake valve open and keep it in an open state, ensuring that the compressor operates in a low-power, non-compressing mode during startup. Once normal operation is achieved, the air supply is stopped and the intake valve then enters its functional state. “\"Air supply under wind load, air release without wind\" is the opposite: during startup, the air volume control mechanism does not supply air; at this time the intake valve remains in an open state. After startup, air supply begins, and the compression process under load starts. The volume control mechanism includes diaphragms, springs, push rods, etc.

It seems we really do have to keep up with the times: lol Many new terms are quite difficult to understand. Unloader? The scope of the uninstaller is quite broad and vague. It seems to refer to an air compressor here? Does \"unloader\" refer to motor-frequency variable loading? Air defense unloading, cyclic unloading? Inhalation control unload? :P press? Are you referring to positive-displacement compressors? Centrifugal compressor? The piston’s? The turbine’s? The screw’s? Membrane pressure? The gear’s? Oh, is it still a filter press? ? What about the other presses? :P wind? It must refer to one of the natural meteorological indicators; here, does “wind” mean a southeast wind or a northwest wind? What should it be called if it’s a gas in contact with other media? Also, if “wind” here refers to the flow of air, then what about flow rate, velocity, and pressure? On this exclusive chemical engineering forum, are all those tool books and **related standards in this area supposed to be modified as well?:lol Finally, I’ll try to guess based on what you’ve written. The reason you don’t understand this is probably that your understanding of certain concepts is too limited. For example, in cases such as \"loading in windy conditions and unloading in calm conditions\" and \"loading in calm conditions and unloading in windy conditions\", if one understands the principle behind such equipment, it should be clear that the focus is on energy savings or other aspects. If it comes to energy savings, one must consider the adjustment characteristics of the equipment in question in order to determine how to make adjustments that can lead to energy savings. I guess there won’t be any hesitation then. I’m an elderly retired man, and I need to keep learning about new things and terms. However, it’s better to stick to the standard names used in my industry – for example, in the Northeast, people don’t call knees “knees”; instead, they call them “glass covers”. It’s originally a unit of length called mm, but people insist on calling it several silk units, several strands, or several meters – it’s the same principle. It is better to standardize it. I’m sorry, but I have to speak frankly.

I know these are two different uses of the compressor unloader, two modes; I don’t understand much else about it

Loading and unloading does not involve adjusting the opening degree of the intake valves; rather, it determines how many intake valves are in operation
