螺桿(gan)壓(ya)縮機 性能(neng)分析(xi)
螺桿(gan)式空(kong)氣壓(ya)縮(suo)機的(de)主要(yao)(yao)性(xing)能參(can)數即功率(lv)、容(rong)積(ji)流量、吸氣壓(ya)力、出(chu)(chu)口溫度、排(pai)出(chu)(chu)壓(ya)力以(yi)及轉(zhuan)(zhuan)(zhuan)速等。而在螺桿(gan)式空(kong)氣壓(ya)縮(suo)機的(de)設計(ji)中，一(yi)對(dui)相(xiang)互(hu)嚙(nie)(nie)合(he)的(de)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)是一(yi)個非(fei)常重要(yao)(yao)的(de)參(can)數。因為(wei)(wei)(wei)其與壓(ya)縮(suo)機的(de)性(xing)能緊密相(xiang)關。螺桿(gan)壓(ya)縮(suo)機的(de)陰陽轉(zhuan)(zhuan)(zhuan)子(zi)(zi)可以(yi)看作是一(yi)對(dui)相(xiang)互(hu)嚙(nie)(nie)合(he)的(de)斜齒(chi)輪，因此，螺桿(gan)壓(ya)縮(suo)機的(de)陰、陽轉(zhuan)(zhuan)(zhuan)子(zi)(zi)型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)也(ye)要(yao)(yao)滿足嚙(nie)(nie)合(he)定律。轉(zhuan)(zhuan)(zhuan)子(zi)(zi)的(de)齒(chi)面(mian)與轉(zhuan)(zhuan)(zhuan)子(zi)(zi)軸線(xian)(xian)(xian)(xian)(xian)垂直(zhi)面(mian)的(de)截(jie)交線(xian)(xian)(xian)(xian)(xian)稱(cheng)(cheng)為(wei)(wei)(wei)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)。螺桿(gan)壓(ya)縮(suo)機的(de)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)分為(wei)(wei)(wei)對(dui)稱(cheng)(cheng)型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)和(he)不(bu)對(dui)稱(cheng)(cheng)型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)，以(yi)及單(dan)(dan)邊型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)和(he)雙(shuang)邊型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)，齒(chi)頂中心(xin)線(xian)(xian)(xian)(xian)(xian)兩(liang)邊的(de)型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)完全(quan)相(xiang)同時，稱(cheng)(cheng)為(wei)(wei)(wei)對(dui)稱(cheng)(cheng)型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)。反(fan)之，齒(chi)頂中心(xin)線(xian)(xian)(xian)(xian)(xian)兩(liang)邊的(de)型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)不(bu)同時，稱(cheng)(cheng)為(wei)(wei)(wei)不(bu)對(dui)稱(cheng)(cheng)型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)。只在轉(zhuan)(zhuan)(zhuan)子(zi)(zi)節圓(yuan)的(de)內部(bu)或者外(wai)部(bu)一(yi)邊具有型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)，稱(cheng)(cheng)為(wei)(wei)(wei)單(dan)(dan)邊型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)。節圓(yuan)的(de)內、外(wai)均有型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)，稱(cheng)(cheng)為(wei)(wei)(wei)雙(shuang)邊型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)。一(yi)般來講，新型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)的(de)開(kai)發設計(ji)直(zhi)接影響了螺桿(gan)式空(kong)氣壓(ya)縮(suo)機的(de)性(xing)能，而螺桿(gan)式空(kong)氣壓(ya)縮(suo)機性(xing)能好壞(huai)也(ye)取決于(yu)型(xing)(xing)(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)的(de)設計(ji)。
螺(luo)(luo)桿(gan)壓(ya)縮(suo)(suo)機(ji)(ji)是依(yi)靠轉(zhuan)(zhuan)子(zi)的(de)(de)不(bu)斷嚙合輸出壓(ya)縮(suo)(suo)氣(qi)體的(de)(de)，因此(ci)主軸(zhou)轉(zhuan)(zhuan)速的(de)(de)變化，對壓(ya)縮(suo)(suo)機(ji)(ji)的(de)(de)容積流量、排氣(qi)壓(ya)力都(dou)會產生(sheng)影(ying)響(xiang)，因此(ci)主軸(zhou)轉(zhuan)(zhuan)速是影(ying)響(xiang)螺(luo)(luo)桿(gan)壓(ya)縮(suo)(suo)機(ji)(ji)性能(neng)的(de)(de)一大(da)因素。當排氣(qi)壓(ya)力增大(da)，壓(ya)縮(suo)(suo)機(ji)(ji)功耗(hao)(hao)也增加(jia)，比功率增大(da)，則(ze)經(jing)濟效益下降，所以(yi)排氣(qi)壓(ya)力對壓(ya)縮(suo)(suo)機(ji)(ji)的(de)(de)能(neng)耗(hao)(hao)有非(fei)(fei)常顯著的(de)(de)影(ying)響(xiang)。同(tong)時(shi)，一些試驗結(jie)果表(biao)明外(wai)界的(de)(de)環(huan)境(jing)溫(wen)(wen)度也會對螺(luo)(luo)桿(gan)壓(ya)縮(suo)(suo)機(ji)(ji)的(de)(de)性能(neng)產生(sheng)影(ying)響(xiang)。中國在不(bu)同(tong)季節與不(bu)同(tong)區(qu)域的(de)(de)氣(qi)溫(wen)(wen)相(xiang)差(cha)較大(da)，環(huan)境(jing)溫(wen)(wen)度不(bu)同(tong)則(ze)壓(ya)縮(suo)(suo)機(ji)(ji)的(de)(de)吸氣(qi)溫(wen)(wen)度也不(bu)同(tong)，這一參數將直接影(ying)響(xiang)了螺(luo)(luo)桿(gan)壓(ya)縮(suo)(suo)機(ji)(ji)的(de)(de)性能(neng)。因此(ci)，對于以(yi)上影(ying)響(xiang)螺(luo)(luo)桿(gan)壓(ya)縮(suo)(suo)機(ji)(ji)性能(neng)的(de)(de)因素進(jin)行分析，將對螺(luo)(luo)桿(gan)壓(ya)縮(suo)(suo)機(ji)(ji)的(de)(de)使(shi)用產生(sheng)非(fei)(fei)常大(da)的(de)(de)幫助(zhu)。 |
