三螺杆泵特点:
1、结构简单:泵本身仅三根螺杆组成,但有多种结构形成,一般小流量,0.2-6.5m3/h泵的泵体和衬套合为 一个卧式安装,轴封为机械密封。中等流量以上的泵衬套为一单独的零件固定于泵体内。大流量泵多制成双吸结构。轴根据输送的介质不同有端面机械密封和填料密封两种。船用泵的原动机为交流船用电机。
2、寿命长:三螺杆泵的主要螺杆是由电动机驱动。主、从螺杆之间,螺杆与衬套之间皆有一层油膜保护,因泵的机械摩擦极小,寿命堪称半*性。
3、所输的液体在泵内作轴向匀速直线运动,故压力脉动小,流量稳定,噪音低,由于转动部分惯性小,则起动力矩和振动很小。
4、具有高吸入能力。
5、为保证泵、电机及管路系统安全,中等流量以上的螺杆泵均带有安全阀,当压力超过安全阀设定压力时,高压油将回流至泵的进口。
