1. 三螺桿泵是依靠泵體與螺桿所形成，當(dāng)主動(dòng)螺桿轉(zhuǎn)動(dòng)時(shí)，帶動(dòng)與其嚙合的從動(dòng)螺桿 一起轉(zhuǎn)動(dòng)，吸入腔一端的螺桿嚙合空間容積逐漸增大，壓力降低。液體在壓差作用下 進(jìn)入嚙合空間容積。當(dāng)容積增至zui大而形成一個(gè)密封腔時(shí)，液體就在一個(gè)個(gè)密封腔內(nèi) 連續(xù)地沿軸向移動(dòng)，直至排出腔一端。這時(shí)排出腔一端的螺桿嚙合空間容積逐漸縮小 

   Main fields of application
   Main fields of application are oil-firing and power engineering;
   hydraulic, maritime, and offshore engineering; machine tools;
   the chemical and petrochemical industries, the food industry,
   and the pulp and paper industry.
   Design
   The SN series is a three-screw, self-priming screw pump with
   hardened and ground spindles that rotate in a replaceable
   casing insert.
   The idler screws are hydraulically driven and axial thrust is
   fully compensated hydrostatically. A groove ball bearing
   lubricated with the pumped liquid or an external greaselubricated groove ball bearing holds the drive screw in place.
   The shaft is sealed with either shaft seal rings or mechanical
   seals. A return pipe connects the seal chamber with the
   suction chamber. As a result, regardless of the current
   discharge pressure, only the suction/inlet pressure will affect
   the shaft seal.
