多吸头排污泵的优点

多吸头排污泵
一、多吸头排污泵的工作原理

多吸头排污泵是容积来的一种,图2-10是其结构简图。它是靠泵体、泵盖、偏心转子和滑片之间形成的容积(称基元容积)的周期性变化吸、液体泵。由图可看出、转子为圆柱形,转子上有若干个槽,每个槽内置有滑片。转子在壳内偏心安装,其偏心e。滑片可在转子的糟内径向滑片就离心力、弹簧液体压力压向壳体,使滑片端部紧贴壳体而保证密封。吸、排出口靠转子与壳体之间很小的间隙密封分开。
    当转子旋转时,在吸侧的基元容积不断增大,将液体吸基元容积。当基元容积达最大值时,基元容积与吸口脱离而与排出口连通。转子继续旋转,基元容积逐渐变小,将液体排出。转子旋转一周,滑片在槽内往复一次,各基元容积变大、变小一次,完成一次吸人、排出过程。
    若将泵做成偏心距可变化的结构,则可以调节流量。若制成一转中两次吸、两次排出的结构,则称双作用多吸头排污泵

Multi-suction sewage pump one, multi-suction sewage pump working principle, multi-suction sewage pump is a volume to one, figure 2-10 is its structure Diagram. It is by the pump body, pump cover, eccentric rotor and between the formation of the volume (called unit volume) of the periodic change of suction, discharge liquid pump. As can be seen from figure, the pump rotor is cylindrical, the rotor has a number of slots, each slot is equipped with a slide. The rotor is installed eccentrically in the pump casing, and its ECCENTRICITY IS E. The sliding vane can slide radially in the slot of the rotor. The sliding plate is pressed against the shell by Centrifugal Force, spring force or liquid pressure, so that the end of the sliding plate is pressed against the Shell to ensure sealing. The inlet and outlet are sealed apart by a small gap between the rotor and the shell. As the rotor rotates, the unit volume on the suction side increases and the liquid is sucked into the unit volume. When the primary volume reaches the maximum, the monomer volume is separated from the suction port and communicated with the discharge port. As the rotor continues to rotate, the volume of the element decreases and the liquid is discharged. Rotor rotation around, slide in the slot to and fro once, the volume of each unit increased, decreased once, to complete a suction, discharge process. If the pump into a variable eccentricity structure, you can adjust the flow. If made into a two-time inhalation, two-time discharge structure, it is called double-acting multi-suction sewage pump.
