Control mode provides gas load / no load

Post by: Admin Dept: BBT Nôi dung máy nén khí Date posted: 08/06/2016

This mode refers to the control input of air through the valve gate
into. That is, when the pressure reaches the upper limit, the valve inlet closes
and the compressor will go into a state of no-load operation; when the pressure is below
the lower limit, inlet valve opens and the compressor will go into a state of active
load. Compressor does not allow load operating condition during the term, the rated power of the motor is choose according to actual needs major and most common is designed overcapacity. The boot device subject to greater wear and tear and that is cause for reduced motor life, thus heavy maintenance work. Although the method has been applied voltage drop used, starting current is still very large, it can affect the stability of the grid and affect the safe operation of the device power consumption is another. Moreover, in all cases the operation is associated procedures and motivations of Compressors unsupported adjust the speed, so that the change of pressure and flow can not be used directly to reduce speed and adjust power output accordingly, and the motor does not allow startup routine that causes the motor remains idle while consuming a very small amount of gas, which consume large amounts of power. Finished the load / unload frequent cause pressure changes throughout the entire pipeline, and working pressure will shorten unstable life of the compressors . Although there were a few adjustments for Compressors (such as adjustable valve, adjustable load) even in the case of little traffic, reduced power consumption and negligible due to motor continuous rotation.

This is the most important equipment for compressed air system (it is considered as the heart, system), because Compressors Direct to produce compressed air supply to the devices and locations in need using compressed air.

Some solutions to save energy

First thing to note for the compressed air system pressure drop pressure loss is a phenomenon that reduces the pressure from the air compressor to use protection.

How to rationalize pressure compressor

After the survey, experts ECC made solutions. Separating the spray using compressed air (10%) and the compressed air supply for the actuators (10%) with compressed air for the furnace section pasteurized (80%) according to the following options
