The instantaneous current capacity may demonstrate through the nixietube, provides the craft data reference for the operator.8031If the system the setting value carries on again the current capacity actual value the comparison, calculates the control quantity after the PID adjustment operation vi, again transforms into the electric current output signal, after but controls the silicon-controlled rectifier after the enlargement the breakover angle, the realization adjusts the slippery difference electrical machinery magnetic clutch exciting current the function, thus the adjustment implementing agency slippery difference electrical machinery rotational speed, causes to transport on the leather belt the material current capacity to stabilize as far as possible nearby the setting value, and has the good static target and the dynamic performance.

瞬间流量可通过数码管显示出来，为操作人员提供工艺数据参考。8031系统再将流量实际值与其设定值进行比较，经PID调节运算后计算出控制量vi，再转换为电流输出信号，而后经放大去控制可控硅的导通角，实现调节滑差电机电磁离合器励磁电流的功能，从而调节执行机构滑差电机的转速，使输送皮带上的物料流量尽可能稳定在设定值附近，并具有良好的静态指标和动态性能。问题补充：希望大家不要给机器翻译的答案，我想要人工翻译的，谢谢大家了

SWS is not rubbish station, not cogged, what had not done to brush discharge, the dirty business that buys discharge and so on (because we are not to rely on to brush discharge,mix advertising, doing the) of originality match and originality product really however, put on record the data is complete, website structure did not change greatly, company information and connection pattern are comprehensive and exact, title character and website content are consistent, be what reason after all?

SWS不是垃圾站，没有作弊，没有搞过什么刷流量，买流量之类的龌龊事情(因为我们不是靠刷流量混广告的，而是真真正正做创意比赛和创意产品的)，备案资料完整，网站结构没有大的变动，公司信息及联系方式全面准确，title文字与网站内容一致，到底是啥原因呢？

Engineering College, Air Force Engineering University, Xi'an Shaanxi 710038, ChinaAbstract: The math model of the movement, flux and control system of position pump was established by analyzing its working principle, and its hydraulic system simulation model was established based on AMESim. The pressure and flux pulsation of the position pump was analyzed, and the pressure and flux was calculated by simulation when there are sign of wear for the position pump and system flux change.
