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, 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, torque inertia ratio big oil-free screw compressor 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, maintenance costs l screw rod air compressor accessories oil maintenance and replacement: screw oil has a decisive influence on the quality of the injection screw machine performance, good oil has good oxidation stability, separation rapid, clear bubble of good, high viscosity, good corrosion resistance, and therefore, the user must use pure special screw air compressor oil company. Fine oil separator maintenance replacement: Oil fine separation screw lubricant and compressed air is a separate component, normal operation, the oil fine separation around 3000 hours in the life of Qin Wei air compressor, but the quality of the lubricant and air filtering accuracy has a huge impact on their life. Visible in the harsh environment must be reduced air filter replacement cycle maintenance air compressor parts, even considering the installation of the front air filter. Fine oil separator pressure difference before and after the expiration or must be replaced after more than 0.12mpa. Otherwise it will cause motor overload, damage the oil separator fine run oil. REPLACE: Remove the lid of the control of oil and gas fittings are installed on. Air filter is to filter the air of dust dirt components, clean filtered air into the compression chamber of the screw rotor compressor. Due to the internal screw clearance allowed only within a particle filter 15u. If clogged air filter is damaged, a lot more than 15u of particulate matter into the screw machine cycle, not only greatly reduce the oil filter, oil fine separation of the core of the life of Qin Wei air compressor, air compressor, air compressor Qin Wei, strong technological strength by Wei Qin Xianyang compressor Limited. Xianyang Qin Wei Compressor Co. (www.xykyj.cn/) strong, credible, Xianyang in Shaanxi compression, separation equipment industry has accumulated a large number of loyal customers.
