在螺旋挤出机运行中,泥缸里的泥料被螺旋绞刀不停地搅动翻滚、挤压,推向机头,挤出机口成为尺寸规范的泥条。在这一过程中,不仅泥料颗粒之间互相摩擦,泥料还要和绞刀、泥缸、机头、机口的内壁摩擦,这些都要产生热,使泥缸升温,这是不可避免的。在正常情况下,这些热量随泥条一同被挤出机口,泥缸表面虽然发热,但不烫手,这是正常的。如果泥料在泥缸里翻滚、搅动的运动量大于其推向前进的运动量,泥条挤出速度缓慢,其所带出 During the operation of the screw extruder, the mud in the mud tank was constantly tumbled by the screw cutter, squeezed and pushed to the head, and the extruder port became a size-standardized mud stick. In this process, not only the mud particles rub against each other, but also the mud and reamer, mud tank, head, the mouth of the inner wall friction, which must produce heat, so that the mud tank temperature, which is inevitable of. Under normal circumstances, these heat are squeezed out of the mouth along with the mud, mud surface, although the heat, but not hot, it is normal. If the mud tumbling in the mud tank, the amount of agitation is greater than the amount of movement to push forward, mud extrusion speed is slow, which brought out
