The invention discloses a constant-temperature automatic control system for circulation water pumps. The automatic control system is characterized by comprising a circulation water pump, a frequency converter connected with the control end of the circulation water pump, a pressure adjuster connected with the frequency converter, a temperature adjuster connected with the pressure adjuster, a pressure sensor which is arranged on the water outlet of the circulation water pump, a temperature sensor which is arranged on the water inlet of the circulation water pump, and a temperature signal conversion module which is connected with the temperature sensor, wherein the pressure sensor is also connected with the pressure adjuster, and the temperature signal conversion module is connected with the temperature adjuster. The temperature of the circulation water in the circulation water pump can be automatically adjusted, so that the circulation water can be kept at the constant temperature, the heat energy can be completely utilized and prevented from being wasted. The pressure of the circulation water in the circulation water pump is automatically adjusted, so that the circulation water pump is kept at the best working state and the working life of the circulation water pump is prolonged.
Description
technical field [0001] The invention relates to the field of automatic control, in particular to a constant temperature automatic control system for a circulating water pump. Background technique [0002] At present, the flow and pressure difference of the circulating water pump system are adjusted by valves and bypasses. Therefore, there are inevitably large interception losses, large flow, high pressure, and low temperature differences. The flow rate of the water pump is automatically adjusted according to the change of the temperature, which leads to the temperature of the circulating water not being able to fully dissipate heat at the user end, and it flows back to the heat source, causing unnecessary waste. At the same time, it is also impossible to maintain a constant temperature value of the circulating water. In this case, this method is not applicable. How to solve the above problems is an urgent task for people at present. Contents of the invention [0003] The...
