【正文】 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。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%.), over the long term, this will be no small cost.3 oil loss The actual users experienced all know, oil loss under the condition of the first victims will be the gear box. Belt drive system is not the existence of such security problems.4 according to user requirements design working pressure The working pressure and manufacturers usually user requirements of the standard model of the pressure is not pletely consistent. For example, the user39。螺桿壓縮機是容積式壓縮機中的一種，空氣的壓縮是靠裝置于機殼內互相平行嚙合的陰陽轉子的齒槽之容積變化而達到。而在螺桿式空氣壓縮機的設計中，一對相互嚙合的轉子是一個非常重要的參數(shù)。螺桿壓縮機的轉子型線分為對稱型線和不對稱型線，以及單邊型線和雙邊型線，齒頂中心線兩邊的型線完全相同時，稱為對稱型線。一般來講，新型線的開發(fā)設計直接影響了螺桿式空氣壓縮機的性能，而螺桿式空氣壓縮機性能好壞也取決于型線的設計。中國在不同季節(jié)與不同區(qū)域的氣溫相差較大，環(huán)境溫度不同則壓縮機的吸氣溫度也不同，這一參數(shù)將直接影響了螺桿壓縮機的性能。 雙螺桿壓縮機的工作過程：電動機經聯(lián)軸器、增速齒輪或皮帶帶動主轉子，由于兩轉子互相嚙合，主轉子即直接帶動副轉子一同旋轉，在相對負壓作用下，空氣吸入，在齒峰與齒溝吻合作用下，氣體被輸送壓縮，當轉子嚙合面轉到與機殼排氣口相通時，被壓縮氣體開始排出。 清潔濾芯步驟如下： ，以絕大部分重而干灰沙。 冷卻器 冷卻器管子內，外表面要特別留意決對保持清潔，否則將降低冷卻效果，應工作條件，定期清潔。 調整步驟如下： ； ，則松開鎖緊螺母并旋緊定位螺栓半圈，閥開過遲則松開鎖 緊螺母約一圈并松開定位螺栓半圈。許多活塞壓縮機的用戶開始改用螺桿空壓機，由于對螺桿壓縮機的使用維護不了解，導致頻繁發(fā)生故障，從而引起用戶和企業(yè)之間發(fā)生矛盾。還有就是螺桿壓縮機的耗材部分要定期更換主要有潤滑油、油過濾器、進氣過濾器、油分濾芯等等值得注意的是在環(huán)境不同的地方更換的頻率也是有所區(qū)別的，所以要對螺桿壓縮機做好每天的使用和檢查記錄。這種情況顯然是極少的。傳動比較優(yōu)良的齒輪傳動效率可達98%~99%,優(yōu)良的皮帶傳動設計在正常的工作條件下亦可達到99%的效率。一般為安全起見。通常用戶要求的工作壓力與制造商之標準機型的壓力并不完全一致。代表現(xiàn)代技術的皮帶傳動設計制造商只需簡單地改變皮帶輪的直徑并可將工作壓力設計得與用戶要求完全一致，這樣用戶用同功率的馬達卻可獲得更多的風量。對于皮帶傳動空壓機，根本不存在這種為題。對于齒輪傳動空壓機，當馬達或轉子軸承損壞時，往往會殃及相連重要部件造成直接和間接雙重損壞
