摘要:
Screw rotation speeds and screw rotating torques are measured at predetermined time intervals during metering and substituted into a previously-assumed function to determine a maximum screw rotating torque at each screw rotation speed. An allowable upper limit of screw rotating torque is set for each screw rotation speed on the basis of the determined maximum screw rotating torque. If a screw rotating torque exceeding the allowable upper limit is detected during metering after the allowable upper limit is set, the screw rotation is stopped or changed.
摘要(中):
在计量期间以预定的时间间隔测量螺杆转速和螺杆旋转扭矩,并将其替换为先前假定的功能,以确定每个螺杆转速下的最大螺杆转动扭矩。 基于所确定的最大螺杆旋转转矩,对每个螺杆转速设定螺杆转矩的允许上限。 如果在设定允许上限之后,在计量期间检测到超过容许上限的螺杆转矩,则螺杆旋转停止或改变。
