威格士VICKERS齿轮泵运行维护1、起动：
（1）启动前检查全部管路法兰，接头的密封性。
（2）盘动联轴器，无摩擦及碰撞声音。
（3）启动应向泵内注入输送液体。
（4）启动前应全开吸入和排出管路中的阀门，严禁闭阀启动。
（5）验证电机转动方向后，启动电机。
2、停车：
（1）关闭电动机。
（2）关闭泵的进、出口阀门。
威格士PEP－II泵的齿轮与轴共为一体，采用通体淬硬工艺，可获得更长的工作寿命。“D”型轴承结合了强制润滑机理，使聚合物经轴承表面，并返回到泵的进口侧，以确保旋转轴的有效润滑。这一特性减少了聚合物滞留并降解的可能性。精密加工的泵体可使“D”型轴承与齿轮轴配合，确保齿轮轴不偏心，以防齿轮磨损。Parkool密封结构与聚四氟唇型密封共同构成水冷密封。这种密封实际上并不接触轴的表面，它的密封原理是将聚合物冷却到半熔融状态而形成自密封。也可以采用Rheoseal密封，它在轴封内表上加工有反向螺旋槽，可使聚合物被反压回到进口。为便于安装，制造商设计了一个环形螺栓安装面，以使与其它设备的法兰安装相配合，这使得筒形法兰的制造更容易。
威格士PEP－II齿轮泵带有与泵的规格相匹配的加热元件，可供用户选配，这可保证快速加温和热量控制。与泵体内加热方式不同，这些元件的损坏只限于一个板子上，与整个泵无关。
威格士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间，降低挤塑温度及压力脉动以提高生产率及产品质量
