Based on GB 12021.4-2013 electric washing machine energy efficiency and water efficiency limit value and grade, it is required to measure the water consumption of the washing machine in the whole process of specific washing. In view of the above, this paper studies the application of PID constant pressure water supply technology in washing machine water efficiency detection equipment, and proposes a Siemens 200 smart based on the research and analysis of the needs and background of washing machine water efficiency detection, and combined with the problems existing in the current detection of washing machine water efficiency. The design of PID constant pressure water supply for washing machine water efficiency detection system in PLC proposes a method to use PID constant pressure water supply technology to improve the performance and accuracy of water efficiency detection equipment. It includes the design of system hardware, the design of control logic, the detailed analysis of the process and control requirements of the detection and control system, and the control and PID monitoring and self-adjustment of PLC are realized through the final online debugging. The use value of the detection system is large, and it has a good detection application prospect.
Firstly, this paper expounds the development of dishwashers in recent years, and expounds the current situation and drawbacks of traditional heating devices in use according to the testing requirements of dishwashers. The uniform indirect heating device is designed to meet the requirements of the preparation process of high hardness water source heating, and the use state of the pipeline before and after the complete construction of the uniform indirect heating device. The whole system flow and PLC simulation are explained in detail. Finally, the feasibility and advantages of this scheme in dishwasher testing system are obtained.
