SNH440R54U8W2三螺杆泵机械密封
三螺杆泵是依靠泵体与螺杆所形成,当主动螺杆转动时,带动与其啮合的从动螺杆 一起转动,吸入腔一端的螺杆啮合空间容积逐渐增大,压力降低。液体在压差作用下 进入啮合空间容积。当容积增至zui大而形成一个密封腔时,液体就在一个个密封腔内 连续地沿轴向移动,直至排出腔一端。这时排出腔一端的螺杆啮合空间容积逐渐缩小
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.
