详细介绍
3QGB三螺杆保温泵是 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,而将液体排出。三螺杆保温泵的工作原理与齿轮泵相似,只是在结构上用螺杆取代了齿轮。表为各种螺杆泵的特点和应用范围。三螺杆保温泵的流量和压力脉冲很小,噪声和振动小,有自吸能力,但螺杆加工较困难。泵有单吸式和双吸式两种结构,但单螺杆泵仅有单吸式。三螺杆泵必须配带安全阀(单螺杆泵不必配带),以防止由于某种原因如排出管堵塞使泵的出口压力超过容许值而损坏泵或原动机。
结构与工作原理:
螺杆保温泵是利用螺杆的回转来吸排液体的。中间螺杆为主动螺杆,由原动机带动回转,两边的螺杆为从动螺杆,随主动螺杆作反向旋转。主、从动螺杆的螺纹均为双头螺纹。
