摘要：针对微藻在生长过程中对温度要求较高,需要保持在适宜的温度范围内,设计了以Siemens S7-200 PLC组成微藻光生物反应器的控制系统。该光生物反应器加热系统利用温度传感器采集藻液中温度信号,将信号输入到PLC中。PLC对温度信号进行运算,输出信号控制加热棒工作,实现了藻液冬季温度的自动恒温控制。经过试验表明,该加热系统在藻液温度设定值为30℃时,温度超调不超过1.5℃,超调量小于7.5%,静差小于±0.5℃,具有控制精度高、稳定性好的优点。光生物反应器采用该加热系统后,藻液的光密度由0.29增长到1.28,污水中的COD的去除率达到79.3%,TN的去除率达到65.07%,TP的去除率达到83.03%,因此该光生物反应器加热系统可以用于微藻的培养,并且微藻在光生物反应器内对污水的处理效果较好,具有良好的应用前景。

摘要：目前,油田小修作业需人工将抽油杆、油管(以下简称“管杆”)转至动力猫道上,作业频繁重复,工人劳动强度大,安全性能低。为解决此问题,设计了一种翻转式上下管杆装置,由翻转模块、夹紧模块、支撑模块、高度调节模块组成,通过摆动缸将管杆由排管架翻转至猫道上,实现对管杆的精确控制,避免了管杆因重力因素对猫道的冲击。使用Solid Works软件建立油田小修作业上下管杆装置整体的三维模型,对各模块进行了详细的结构设计,并且对摆动缸作业过程中所需力矩进行了详细的计算,使用Adams软件建立动力学仿真分析模型,对管杆的不同夹持布点和夹取方式进行了分析,并验证了液压驱动元件的选型合理性,为装置的设计提供了理论支撑。
