How to judge pneumatics machine energy-saving? What is energy-saving pneumatics machine?
QiAir Compressor
Stipulate to three-phase asynchronous electromotor 3 ran area to make following announcement related the country: Laden rate runs a division for economy between 70%~100% ; Laden rate is between 40%~70% run a division commonly; Laden rate is in 40% run a division to be not economy below. Capacity of if electric machinery chooses. . .
One, choose energy-saving electromotor: Common electromotor lags behind because of its design, choose material cheap, power consumption is very big, and efficient now electromotor, optimize its interior to design, reduce all sorts of needless loss, the cupreous winding that chooses a few high quality and silicon steel piece, can better ensure electromotor moves for a long time. Efficient electromotor and common electromotor are compared, loss dropped 20%~30% , efficiency rose 7% the left and right sides, estimation of investment pay back period is commonly arrive two years, some is a few months even. As a whole, efficient electromotor efficiency is tall, because this uses efficient electromotor to replace old-style electromotor imperative, at present the compression of the enterprise air equipment is to use old-style motor more very, as time passes, also be the expense with not little brushstroke. Capacity of electromotor of 2 proper choices achieves energy-saving: Stipulate to three-phase asynchronous electromotor 3 ran area to make following announcement related the country: Laden rate runs a division for economy between 70%~100% ; Laden rate is between 40%~70% run a division commonly; Laden rate is in 40% run a division to be not economy below. Choice of capacity of if electric machinery is impertinent, electric energy expenses can rise greatly accordingly. Pneumatics aircraft manufacturer uses appropriate motor, those who be is to raise power factor, laden rate, such ability reduce power loss, save electric energy better. 3. The power factor of electromotor does not have merit compensation: To do not have merit compensation, electromotor raises power factor, reduce power loss. Power of have rendered great service of power factor = : Inspect in power, generally speaking, too small conference causes power factor electric current is too big, when power supply tension is constant, criterion smaller electric current jumps over power factor big. So power factor wants as far as possible tall, ability achieves better energy-saving result. 4. Use magnetic chamfer wedge to replace former chamfer wedge. The action of magnetic chamfer wedge is the empty loss carrying iron in reducing asynchronous electromotor. The harmonic magnetic flux that alveolar effect causes inside electric machinery, the air that produces in core of stator, rotor so records add iron loss. Ministry of tine of stator, rotor staggers to having from time to time again sometimes, magnetic flux of bunch of tooth flank tine happens fluctuant, but in layer of tooth flank line n/ele be induced by backset produces exterior loss. Stator, rotor calls arteries and veins in the loss of n/ele be induced by high frequency and add iron inside core brace up loss. Arteries and veins brace up loss and exterior loss close weigh high frequency and additional loss, they occupy the 70%~90% of loss of electric machinery stray, another 10%~30% call laden and additional loss, arise by leakage magnetic flux. Although use magnetic chamfer wedge to be able to make start torsion,drop 10%~20% , but the iron loss that uses the electromotor of magnetic chamfer wedge to compare the motor that uses common chamfer wedge can reduce 60k, and very suit to carry for nothing or carry started motor gently to transform. 5. Circle timing of liquid of line type electromotor: Because starter of resistor of traditional product liquid is existing all sorts of disadvantageous problems, make pneumatics aircraft manufacturer very pained, and technology of timing of resistor of new-style now liquid, in order to change plate the size of span adjustment resistor, will achieve the goal of stepless speed regulation. At the same time this also has good startability, because it is long-term the reason of electrify, brought calorific the problem that warm up, and chose distinctive framework and sound hot exchange system, its working temperature is adjusted to come equal status. The electric machinery that wind a string uses technology of liquid resistor timing, reliable, installation maintains market expediently, energy-savingly, easily reach investment low good point is an organic whole, there is good extensive to use a sex in the industry, not tall to requirement of a few timing, range is not wide, the electromotor of the type that wind a string of not frequent timing, having good effect.
