摘　　要：通过在吸入口前增加相应的滤芯过滤器并采用密封活塞将轴承与石油隔开，单独润滑，使三螺杆泵可以可靠地使用于石油输送场合．It is necessary to research a transferring petroleum tri screw pumps.A relative candle filters must be fit in front of the input,so that the big solid particles can be filtered from petroleum, and the small solid particles will go with petroleum.The reliable sealing ways divide the bearing from petroleum and lubricate by itself,keeping the tri screw pumps work normally.

关 键 词：螺杆泵 滤芯过滤器 密封 润滑 石油输送设备
