摘要本文針對無油螺桿式真空泵中一種常用的單頭等螺距梯形級齒的螺桿轉子型線，研究討論了二轉子級齒間的干涉問題。Surface, the easliy wear and tear parts use grinding - resistant material, extruding part use variable cylinder diamethe extruder with compact structuures, transmission gear with hard gear ter detachable pitch, great extruding p0ressure, high vacuum degree, low loading capacity ( electricity - saving more than 25 % than the same product ). it reaches advanced domestic level andcan replace imported items. it is suitable to produce hollow brick with high hole ratio, coal waste rock hollow bricks, shale hollow bricks, prower coal ash hollow - bricks. the extruder won the scienttific and technological progress pride of the lst building material scientific and techniques achievement exhibition in jiangsu province and the golden prize of the mational brick and tile energy - saving lxln achievement
該機結構緊湊、傳動齒輪均系硬齒面，易損件採用耐磨材料、擠出部分採用變缸徑、變螺距、擠出壓力大、真空度高，裝機容量低（比同類產品節電25 % ） ，性能優于進口同類設備，適用生產高孔洞率空心砌塊、煤矸石、頁巖、精煤灰空心磚及各類高摻入量粉煤灰磚和低塑性原料磚，該機在江蘇省首屆建材科技成果展覽會科技進步獎； 94全國磚瓦節能四新成果展覽會金獎，西安國際博覽會金獎。
