Abstract

The invention discloses an automatic constant temperature control system based on a frequency stabilization circuit and applied to a circulating water pump. The automatic constant temperature control system comprises the circulating water pump, a frequency converter connected with a control terminal of the circulating water pump, a pressure regulator, a temperature regulator, a pressure sensor arranged at a water outlet of the circulating water pump, a temperature sensor arranged at a water inlet of the circulating water pump and a temperature signal conversion module connected with the temperature sensor, wherein the pressure regulator and the temperature regulator are connected with the frequency converter, the pressure sensor is connected with the pressure regulator, and the temperature signal conversion module is connected with the temperature regulator. The automatic constant temperature control system is characterized in that the frequency stabilization circuit connected with the temperature signal conversion module is further arranged. The automatic constant temperature control system can better control the temperature signal conversion module through the frequency stabilization circuit, so that the temperature signal conversion effect is better, and the efficiency is high.

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 based on a frequency-stabilized oscillating circuit. 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 a...
