【正文】 s design and manufacturing level.2 noload power consumptionFor direct gear driving mode, noload pressure generally maintained at more than , some even as high as 4bar, to ensure that the gear lubrication. The belt drive mode, theory of noload pressure can be zero, because the rotor into the oil to lubricate the rotor and bearing. General for the sake of safety, the pressure maintained at about . Taking gear pressor a 160kW for example, 8000 hours per year, of which 15% (1200 hours) time for noload, the machine every year than the same power air pressor belt drive more consumption of electricity (28800kwh noload assuming two machine pressure is 2bar, the difference of the energy consumption of about 15%.), ov。 4, replacement of the belt is quite easy and fast, and do not need to adjust the original setting。s air ventilation, pressure station power supply cable and air switch specifications, water pressure and flow, exhaust pipe sizes have guidance. The instructions also principle and structure of the machine are described in detail, there are certain basic knowledge of mechanical and electrical personnel through carefully reading, can make correct judgement and treatment for mon problems. There is a consumable part of screw pressor to the regular replacement of main lubricating oil, oil filter, air filter, oil filter, notable is replaced in the environment of different parts of the frequency also has the difference, so the screw pressor to daily use and inspection record.Transmission gear and belt drive In the transmission system of the air pressor, generally can be divided into direct transmission and belt drive, longterm since, two kinds of transmission way merits has been one of the focus of the debate. Direct drive screw air pressor refers to the spindle motor through a coupling and a gear to drive the rotor, direct drive which in fact is not the real meaning of. Direct drive on real significance is directly connected to motor and rotor (coaxial) and the speed. This is obviously a little. So that the direct drive no energy consumption point of view is wrong. Another way of drive for belt drive, the drive through the belt wheels of different diameters is allowed to change the rotating speed of the rotor. Belt drive system discussed below is a representative shall meet the following conditions of the automation system of the latest technology: Belt 1, each operating state of tension reached the optimal value 2, by avoiding the tension, greatly prolong the working life of the belt, while reducing the motor and rotor bearing load。 4 observe the working pressure, slowly clockwise pressure regulating bolt, when the pressure reaches the set value, the safety valve does not open or up to the specified value before the open, it must be adjusted.The adjustment procedure is as follows: 1 remove the cap and seal。 2 connected to water。 while the worm pressor is a uniaxial volume type rotary pressor, the meshing pair is posed of a worm wheel and two symmetrical layout, wall by the worm screw groove and the star wheel tooth surface and the casing form element volume closed, but the problem is the Star blade material has yet to be improved. The main performance parameters of screw type air pressor power, volume flow rate, pressure, exit temperature, discharge pressure and speed etc.. And in the design of screw air pressor, rotor of a pair of mutually meshing is a very important parameter. Because the performance of the pressor is closely related with the. The Yin and Yang of screw pressor rotor can be regarded as a pair of mutually meshed helical gear, therefore, the Yin and Yang of screw pressor rotor profile, but also to meet the meshing law. Rotor tooth surface and the vertical axis of the rotor section called rotor profile. The rotor profile of screw pressor is divided into symmetric and asymmetric line profile, and unilateral and bilateral type line profile, tooth top center line on both sides of the line are identical, called the symmetric line. On the contrary, the tooth top center line on both sides of the line is not at the same time, called asymmetric line. Only one side has a line in the internal or external rotor pitch circle, called single line. Pitch circle, are stylish lines, called bilateral profile. Generally speaking, the development and design of new line directly affect the performance of screw air pressor, design of screw air pressor performance also depends on the type of line. Screw pressor is constantly engaged on the rotor output pressed gas, therefore the spindle speed variation, volume flow rate, the exhaust pressure of the pressor will be affected, so the spindle speed is a major factor affecting the performance of screw pressor. When the exhaust pressure increases, pressor power consumption also increases, power increases, the decrease of economic benefit, so it has significant effect on energy consumption and exhaust pressure of the pressor. At the same time, some test results show that the external environment temperature will influence the performance of screw pressor. China in different seasons and different regions of the temperature difference, air temperature and ambient temperature of pressor is different, this parameter will directly affect the performance of screw pressor. Therefore, the factors that influence the performance of screw pressor were analyzed, will have the very big help to use screw pressor. Screw pressor body is divided into two kinds, one kind is the belt transmission type, another kind is direct drive. Compressor belt transmission type which is suitable for 22KW power, is posed of 2 manufacturing according to the speed ratio of the belt pulley power via the belt transmission。（4）速度正弦函數(shù)變化，位置和加速度呈不規(guī)則變化。（7）滾動軸承1.（8）滾動軸承2.（9）排氣端封蓋1.（10）排氣端封蓋2.2. 組裝圖（1）陰陽螺桿嚙合傳動圖（2） 總組裝圖覽3. 仿真圖（1） 陰陽螺桿嚙合連接圖（2）速度為常數(shù)時候的仿真曲線，加速度為0，位置隨時間均勻變化。（5）吸氣端蓋，底板與壓縮箱主體
