Centralized control system for intelligent heat pump cleaning machine

Abstract

Provided in the invention is a centralized control system for an intelligent heat pump cleaning machine. With a temperature sensor and a liquid level sensor that are arranged in a water pool, a heat pump system and a cleaning machine system are combined together by using a PLC module; the PLC module monitors the operating states of the heat pump set and the cleaning machine system in real time; starting and stopping of different heat pump sets and auxiliary heaters can be controlled by the PLC module, so that the energy-saving advantages of the control system is fully reflected; information interaction and centralized control between the two systems can be managed effectively and timely; and on the basis of the data analysis, management becomes convenient and the work efficiency is improved. With a photoelectric switch arranged at the inlet of the cleaning machine, when the PLC control module does not receive a signal transmitted by the photoelectric switch within certain time, a control signal is sent out to control the heat pump set and the cleaning machine to stop working, so that the production time and production rhythm can be arranged scientifically and thus an objective of production cost reduction is achieved.

Description

technical field [0001] The invention belongs to the field of automatic control, in particular to a centralized control system for an intelligent heat pump cleaning machine. Background technique [0002] At present, there is an insurmountable process in both the manufacturing of machinery and equipment or in the manufacturing process of bearings. It is the cleaning of the parts before assembly. After the various mechanical parts are processed, the parts themselves will produce some dirt. It must be cleaned before use; the current cleaning method is high-temperature hot water cleaning, and the high-temperature hot water generated by the heat pump system is transported to the cleaning machine through the pump, and then the parts are cleaned, but this method There are many shortcomings. First, during the cleaning process, the heat pump heating system and the washing machine system operate independently and cannot interact. If any system fails, manual control is required, and the...

[0002] At present, there is an insurmountable process in both the manufacturing of machinery and equipment or in the manufacturing process of bearings. It is the cleaning of the parts before assembly. After the various mechanical parts are processed, the parts themselves will produce some dirt. It must be cleaned before use; the current cleaning method is high-temperature hot water cleaning, and the high-temperature hot water generated by the heat pump system is transported to the cleaning machine through the pump, and then the parts are cleaned, but this method There are many shortcomings. First, during the cleaning process, the heat pump heating system and the washing machine system operate independently and cannot interact. If any system fails, manual control is required, and the degree of automation is not high. Second, the operation Those who cannot obtain real-time temperature values ​​for the temperature of the heat pump system, if the heat pump system does not work normally, breaks down, causing the water temperature to fail to meet the process requirements, it will have an impact on the quality of the cleaning products; As the economic situation changes, the production cycle will also be different accordingly, and the independent control of the heat pump system and the washing machine system sometimes cannot meet the production heat demand, resulting in the process temperature not reaching the standard and affecting product quality; Fourth, users will Production line adjustment, relocation, and reorganization due to production, resulting in a large amount of labor time for equipment management and asset management for statistics and management; fifth, due to the low degree of automation of the cleaning production line, production energy consumption will vary according to the individual capabilities and habits of different operators different, thus causing unnecessary waste of energy
