齿轮泵由一个独立的电机驱动,可有效地阻断上游的压力脉动及流量波动。在齿轮泵出口处的压力脉动可以控制在1%以内。在挤出生产线上采用一台齿轮泵,可以提高流量输出速度,减少物料在挤出机内的剪切及驻留时
外啮合齿轮泵是应用Z广泛的一种齿轮泵,一般齿轮泵通常指的就是外啮合齿轮泵。它的结构如图5-14所示,主要有主动齿轮、从动齿轮、泵体、泵盖和安全阀等组成。泵体、泵盖和齿轮构成的密封空间就是齿轮泵的工作室。两个齿轮的轮轴分别装在两泵盖上的轴承孔内,主动齿轮轴伸出泵体,由电动机带动旋转。外啮合齿轮泵结构简单、重量轻、造价低、工作可靠、应用范围广。
齿轮泵工作时,主动轮随电动机一起旋转并带动从动轮跟着旋转。当吸入室一侧的啮合齿逐渐分开时,吸入室容积增大,压力降低,便将吸人管中的液体吸入泵内;吸入液体分两路在齿槽内被齿轮推送到排出室。液体进入排出室后,由于两个齿轮的轮齿不断啮合,便液体受挤压而从排出室进入排出管中。主动齿轮和从动齿轮不停地旋转,泵就能连续不断地吸入和排出液体。
泵体上装有安全阀,当排出压力超过规定压力时,输送液体可以自动顶开安全阀,使高压液体返回吸入管。
内啮合齿轮泵,它由一对相互啮合的内齿轮、及它们中间的月牙形件、泵壳等构成。月牙形件的作用是将吸入室和排出室隔开。当主动齿轮旋转时,在齿轮脱开啮合的地方形成局部真空,液体被吸A泵内充满吸入室各齿间,然后沿月牙形件的内外两侧分两路进入排出室。在轮齿进入啮合的地方,存在于齿间的液体被挤压而送进排出管。
齿轮泵除具有自吸能力、流量与排出压力无关等特点外,泵壳上无吸A阀和排出阀,具有结构简单,流量均匀、工作可靠等特性,但效率低、噪音和振动大、易磨损,用来输送无腐蚀性、无固体颗粒并且具有润滑能力的各种油类,温度一般不超过70’℃,例如润滑油、食用植物油等。一般流量范围为0.045~30ms/h,压力范围为0.7—20MPa,工作转速为1200—4000r/min。
