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. Power compressor unloading of about 30% to 50% at full load, showing the traditional air compressor has a 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 greatly reduced by improving the specific power input power, for business users to save a considerable amount of electricity air compressor parts, so as to users to further reduce manufacturing costs. 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. Motor direct drive, no slip speed compressor cost, 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, screw compressor maintenance costs have several important parameters, general These parameters determine the use of screw compressor too has his ability to work. Of course, there are some introductory, such as shape size, and weight, etc., these and other parameters relative to screw compressor capacity for work is not so important, in order to allow customers to better understand and more understanding of the screw empty press air compressor, list them on the meaning of its parameters, for reference. 1. One of the parameters of this displacement is ultimately, also known as volumetric capacity, displacement is the called, refers to the volume of gas inside the discharge per unit time, the customer is to buy a screw compressor to use it to compress the gas in order to do some work, so this parameter is relatively important. And different screw compressors have different displacement. 2. The working pressure is called exhaust pressure, its meaning can be seen from the name, is the role of the maximum pressure of the exhaust gas compressor, screw compressor is compressed gases. Generally look at when selecting a machine Cottle air compressor, according to their own situation, is based on this to select different types of machine. 3. Motor power consumption generally refers to the power of the compressor, is matching the motor. The unit is Kw, general industry people are used to refer to the specific parameters of the machine, is one of the very commonly used parameters. 4. Cooling air compressor work when temperatures are generally within the machine are very high, high-speed rotation of the rotor, the naturally generate heat, so they need to cool, otherwise it will burn out the machine, the general cooling mode is air-cooled and water-cooled, General minicomputer, air line, and neutral words, air can be cooled, large machines, the general is water-cooled. 5. This means that the noise screw compressor noise generated when at work, general unit dB (A). 6. screw compressor outlet diameter refers to the size of the trachea, of different sizes with different sized machine will exit diameter Cottle Compressor |??
