Description
Technical field
This utility model belongs to field of air compressor.
Background technology
Common frequency conversion type air compressor machine is with actual pressure and gas consumption in the instant induction system of pressure sensor. Get off immediately to control motor rotary speed (i.e. output) in the premise not changing air compressor machine motor torque (namely dragging the ability of load), via changing compressor rotary speed, carry out the change of responding system pressure, and the system pressure remained stable for (setting value), to realize the on-demand output of high-quality pressure air. When system consumption air quantity reduces, the compression air that now compressor provides is more than system consumption amount, and inverter compressor can reduce rotating speed, reduces output squeezing air air quantity simultaneously; Otherwise then improve motor running speed and increase compression air air quantity, with the system pressure value remained stable for. But converter is when frequency is very low, and output torque is only small, it is impossible to meet air compressor load's requirement; Air compressor machine does not allow to run at low frequency for a long time simultaneously, owing to rotating speed is too low, and its poor work stability, the poor lubrication of the cylinder body of compressor, can increase the weight of mechanical wear, generally be not less than 20Hz and be preferred. So even if when gas consumption is seldom maybe without gas, air compressor machine need nonetheless remain for maintaining certain rotating speed, although air compressor machine is in unloaded state, motor idle running also can consume certain electric energy.
Therefore, it is attempted to technique scheme is improved. Long-time without gas or gas consumption little time, generally adopt the mode saves energy allowing air compressor reduce output " lower frequency limit ", the setting of lower frequency limit sets according to machine performance, occurs without fault alarm and is as the criterion being again started up converter. Because when pressure is lower than on-load pressure, it is necessary to starting air compressor machine, now the air pressure of pipeline is still significantly high, starting load is very big, and converter low-frequency moment is not enough; Running so maintaining certain frequency, this also wastes electric energy.
Another kind of power save mode is air compressor machine dormancy, and sleep mode general at present is simple condition timing mode, and namely at ductwork pressure higher than trigger after setting value, after reaching the time, air compressor machine is shut down.In view of converter low-frequency moment is not enough, start and over current fault usually occur, it usually needs use the power of amplification frequency converter to use, " low load with strong power " this be also a kind of waste. And this simple timework pattern, supply gas pressure is unstable, and response time is long, affect enterprise's production.
