Background technique:
Pressurized air has had the history in century more than one as power source.Along with science and technology development, people have just had further requirement to compressed-air actuated quality.But function ratio such as the transmission of air compressor, protection are more single, most of still rely on contactor, relay and mechanical interlocked be that the control core cabinet is realized, compressor can only move by permanent rotating speed, energy dissipation is more serious.
Needed air horsepower and exhaust pressure, rotating speed have direct relation on the live axle of air compressor, in actual motion, air compressor does not move under specified operating mode, and the height of exhaust pressure directly has influence on the size of actual axle power, exhaust pressure is high more, and required air horsepower is also big more.Secondly, for satisfying the variation at any time of gas consumption, the gas storage gas in the jar must keep certain pressure, present most of factory be 0.6Mpa～0.8Mpa with atmospheric pressure, when the pressure in the cylinder rises when reaching the upper limit pressure air compressor off-load operation, do not produce pressurized gas, the no-load running of motor place, its power consumption still are 25～40% of full load, and this part can finally be wasted; The continuous fluctuation of air pressure also causes a large amount of electric energy to be wasted on the other hand.Existing air compressor has the following disadvantages in the use:
Though 1, main motor star-angle reduced voltage starting, the electric current during starting is still very big, can influence the security of operation of stable and other consumer of electrical network;
2, main motor no-load running often belongs to the non-economy operation, and waste of energy is serious;
Noise was very big when 3, main motor power frequency operation caused compressor operation;
4, the impact of main motor power frequency starting equipment is big, and the wearing and tearing of motor bearings are big, so maintenance workload is big, and the maintenance cost height.
The model utility content:
