Here we do further elaborated on some of the advantages of some of the problems of traditional energy-saving air compressor and air compressor Cottle: a serious power loss. The traditional loading and unloading compressor energy consumption in use: 1, energy-consuming loading after the pressure has reached the desired working pressure, the traditional control methods adopted at its pressure will continue to rise until the unloading pressure. Pressurized process, will occur more heat and noise, and then causing power loss. On the other hand, high-pressure gas before entering the pneumatic components, the pressure demand pressure through the valve, the same energy in the process. 2, unloading energy consumption when the pressure reaches unloaded, compressor unloading valve active open, the motor idling, forming a large energy consumption. Unloading compressor power accounts for about 30% at full load and 50% Cottle air compressor, air compressor visible tradition significant saving space. Second, Cottle energy-efficient permanent magnet synchronous inverter compressor and an ordinary power frequency compressor contrast, we know that the air compressor through "specific power" (input power / displacement per minute) to determine whether the energy-saving , that is, the lower the displacement under the same input power is better than power. Traditional air compressor because the input power is relatively high and therefore use will consume more power, resulting in a lot of waste; and Cottle permanent magnet synchronous inverter compressor is significantly reduced through improved input power than the power of the Qin Wei empty press, for business users to save considerable electricity compressor, so as to further reduce manufacturing costs users. 2, compared to the magnetic field Cottle energy-efficient permanent magnet motor and induction motor is the basis for the motor to achieve electromechanical energy conversion, according to the motor way to establish a magnetic field can be divided into electrical excitation and permanent magnet motors. Compared with the electrical excitation motors, permanent magnet motors Cottle has the following advantages: 1) High efficiency: the abolition of the excitation system losses and improve the efficiency of 5-12%. High power factor, the big moment inertia ratio, the stator current and stator resistance loss is reduced, and the rotor parameters can be measured, controlled performance is good. Direct drive motor, no speed slip, no bearings and connecting transmission efficiency improved by more than 3%. . At present, energy-efficient permanent magnet motors have reached mainstream adoption of a national energy efficiency standards. 2) Low noise: rational design field, flux density distribution, broader and lower operating noise operating frequency range. 3 Cottle, a reduced maintenance costs, the use of the cylinder liner sleeve moisture advantages: 1, for the low, medium pressure cylinder to simplify casting 2, good material available to increase abrasion resistance than the cylinder 3, can increase or decrease its wall thickness, within a certain range to change the diameter of the working chamber, to realize the series 4 cylinder, when compressed air cylinder or a corrosive gas without oil lubrication, available corresponding corrosion resistant material. Disadvantages: adds two numbers and machining and installation work; increasing the likelihood of discharge of the water jacket. Wet cylinder wall thickness of the wall thickness calculation within the same cylinder. Second, the Dry Liner it is pressed in a cylindrical inner wall of the cylinder. Dry liner advantages and disadvantages. 1. Advantages: a, good wear-resistant materials available liner to reduce maintenance workload b, after a removable liner wear off for a rather heavy machining cylinder c, can change the liner thickness, appropriately modified to work lumen diameter d , or for the etching gas cylinder when no oil lubrication, corrosion-resistant materials available appropriate. 2, disadvantages: a, an increase of machining and assembly work, but also an increase of the manufacturing cost. b, replace the cylinder liner, cylinder head to be demolished with a professional tool, therefore, for those casting clean compressed gas cylinder, oiled, often without first processing liner air compressor production Which is good, after removing the cylinder until cylinder wear After re-boring, in pressed into cylinder, but the steel cylinder due to its abrasion resistance is poor, you must set the Dry Liner when oil lubrication. c, in the event of breakage Dry Liner will bring a major accident. d, the presence of the cylinder wall liner thermal worsened.
