【摘要】：目前真空洁具系统工作时冲洗力设定为固定值,真空抽吸时间按最大污物量设定,对于高频率中、低污物量冲洗作业而言,存在空气消耗量的浪费。针对真空吸排系统的特点,研究了节能型洁具真空吸排系统供气量调节方法。其中,真空发生器的吸气流量由等温放出法测得,基于真空吸排系统流量试验数据,使用最小二乘法辨识流量特性参数,对真空收集罐内的压力响应进行仿真并得出洁具真空吸排系统压力响应模型。以此为基础,通过调节供气时间来调整供气量从而调节真空度和冲洗力。与现行的真空洁具装置比较,经过供气量调节设计,节省压缩空气消耗量达30%以上,显示出了很好的发展应用前景。
[Abstract]:At present, the washing force of vacuum sanitary ware system is set to a fixed value, and the vacuum suction time is set according to the maximum amount of dirt. For the high frequency rate, low sewage volume washing operation, there is a waste of air consumption. According to the characteristics of vacuum suction and drainage system, the regulation method of air supply in vacuum suction and drainage system of energy-saving sanitary ware is studied. The suction flow of the vacuum generator is measured by the Isothermal discharge method. Based on the test data of the vacuum suction and drainage system, the flow characteristic parameters are identified by the least square method. The pressure response in the vacuum collection tank is simulated and the pressure response model of the vacuum suction and drainage system of sanitary ware is obtained. On this basis, the vacuum and washing force can be adjusted by adjusting the gas supply time. Compared with the current vacuum sanitary ware device, through the design of air supply regulation, the compressed air consumption is saved by more than 30%, which shows a good development and application prospect.
