【正文】 2 with less than of dry air and air blowing along the opposite direction, the nozzle and the folded paper less distance of 25 mm, and along the length direction, bottom blowing. Grease 3 element, should be dissolved with no foam detergent in warm water wash, the warm water immersion for 15 minutes at least element, and use clean water hose with wash, do not use heating method to accelerate drying, a filter can be washed 5 times, and then discarded reusable. The 4 filter is put in a check, such as thinning, pinhole or damaged should be abandoned.Cooler The cooler tube, outer surface should pay special attention to the decision to keep clean, otherwise it will reduce the cooling effect, should be working conditions, regular cleaning.Gas tank / oil and gas separator Gas tank / oil separator according to the pressure vessel manufacturing standards and acceptance, not arbitrarily modify.Safety valve Installed in the tank / oil and gas separator safety valve inspection at least once a year, adjust the safety valve should have professional and responsible, at least every three months to marathon a lever again, so that the valve opening and closing time, a safety valve to work properly.Test steps are as follows: 1 close the gas supply valve。中英文翻譯The screw air pressor Screw air pressor is the injection of single stage double screw pressor, divided into single screw air pressor and screw air pressor, efficient use of belt drive, drive the host rotation of pressed air, through the oil for cooling the pressed air in the host, the host of air and oil discharge of the mixed gas after coarse, fine two channel separation, the pressed oil separated out in the air, finally get the clean pressed air. Cooler for cooling the pressed air and oil. With reliable performance, small vibration, low noise, convenient operation, few wearing parts, high efficiency is the biggest advantage of. Screw pressor is a new type pressor, air is pressed alveolar ridge volume change installed on the casing are mutually parallel rotor meshing and achieve. The rotor side in the case and it with precision internal rotation so that gas rotor slot between continuously cyclical changes in volume and along the rotor axis, by the suction side to the discharge side suction, pression, exhaust, plete three working process. Twin screw pressor is a double volume type rotary pressor, which is the main (Yang) side (Yin) with two rotor, posed of meshing pair, vice principal of rotor profile of external ponents of the element volume closed with the inner wall of the casing, shortage of twin screw is 40 cubic meters and above machine type to add gear, increase power consumption and prone to head lock。 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 li
