【正文】 s requirements in accordance with the pressure of 10bar, after processing equipment, pipe length and different requirements of sealing, the pressure of air pressor may be 11 or . In this case, the general will install a rated pressure of 13bar e air pressor and in the field to the outlet pressure set for the required pressure. The exhaust volume will basically remain unchanged, because the ultimate working pressure is reduced, but did not increase the speed of rotor. The belt transmission design manufacturers on behalf of the modern technology simply change the belt pulley diameter and the pressure of work designed to be pletely consistent with the requirements of users, so that users with a motor with a power which can get more air volume. For the wheel transmission, is not so easy.The installed 5 air pressor pressure change Sometimes because of technological conditions for the production of the user changes, the design pressure of air pressor of the original purchase may be too high or too low, will change, but for the pressor gear transmission, this work is 。 5, the belt drive system safe and troublefree operation.The parison of transmission1 efficiency.Gear transmission efficiency can reach 98%~99% excellent, belt drive design excellent under normal working conditions and efficiency reached 99%. The difference does not depend on the choice of drive mode, and depending on the manufacturer39。 3, always make sure that the correct belt wheel is connected。 The 2 valve opening soon, loosen locknut and a positioning bolt half ring, valve open too late to loosenThe nut about a circle and release the positioning bolts half circle. 3 repeat detection step, the safety valve set pressure value, still can not open, again adjustment.Motor overload relay The relay normally open contact, must be closed, when the current exceeds the rated value, cut off the motor power supply. The maintenance of screw pressor relative to the piston pressor is to lower the probability of a failure of many, but if use improper maintenance, the advantages of screw pressor is difficult to play. Many users began to use piston pressor screw air pressor, due to the maintenance of screw pressor does not understand, leading to frequent failure, causing the conflict between users and enterprises. So before using screw pressor to his use and maintenance instructions carefully read. Installation place, on the machine39。 The 3 starting unit。 direct drive type is the 1 coupling electric source and host together, worm pressor is directly driven by the worm rotation, while the double screw pressor is required add a gear in order to improve the speed of rotor. The working process of Twin Screw Compressors: motor through a coupling, gear or belt driven by two main rotor, rotor meshing with each other, the main rotor is directly driven by the auxiliary rotor to rotate together, inhaled air in relatively under the action of negative pressure, the peak, and the tooth groove under the agreement, the gas is transported pression, when the rotor meshing surface to and the casing exhaust port, the pressed gas discharge. The working process of screw pressor: motor with coupling or belt to power the worm shaft, driven by the worm gear worm star relative move in grooves, sealing element volume change, gas, transportation pression, when the design pressure, exhaust from the host shell triangle on the left and right symmetrical outlet to the oil and gas separator in the. The host for the housing of screw pressor is provided with a spray hole, depending on the pressure difference, in the process of oil spray to the pression chamber to cool the gas, pressed, the sealing parts gap, and to vibration, noise and lubricating effect Inhalation of dust in the air was blocking filter, in order to avoid premature wear and oil separator of pressor to be blocked, usually run 1000 hours or after a year, to replace the filter, dust, replace the time interval to shorten. Filter repair must stop, reduce stop time, remended for the last new or cleaned standby filter.Clean filter steps are as follows: The 1 to the two end surface of a plane turns tap filter, with most heavy and dry sand. 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 pr
