referring to fig. 5, the difference from the first embodiment is that the drain valve 170 and the water pump 130 can be controlled by a PLC 260, the first control module 150, the second control module 190, the third control module 210 and the fourth control module 230 are integrated on the PLC 260, the water pump 130, the drain valve 170, the casing temperature detection module 140, the liquid level detection module 220, the circulating liquid temperature detection module 200 and the pressure detection module 180 are connected to the PLC 260, the PLC 260 is further connected to a display 250, and the display 250 is used for displaying a casing temperature value, a bottom pressure value of the water tank 100 and a circulating liquid temperature value.
The working principle is as follows:
the system starts to work after being powered on, the casing temperature detection module 140 starts to detect the temperature of the casing of the motor 110, the circulating liquid temperature detection module 200 starts to detect the temperature of the circulating liquid in the water tank 100, the pressure detection module 180 starts to detect the pressure at the bottom of the water tank 100, then the acquired data are sent to the PLC 260 through digital signals, the PLC 260 outputs instructions to the display 250 according to different received digital signals, and the display 250 module displays the casing temperature of the motor 110, the temperature of the circulating liquid in the water tank 100 and the pressure at the bottom of the water tank 100.
The circulating liquid starts to circulate between the cooling pipe 120 on the casing of the motor 110 and the water tank 100 through the water pump 130, and the PLC programmable controller 260 can control the rotating speed of the water pump 130 according to the temperature detected by the casing temperature detection module 140, so as to control the circulating speed of the circulating liquid, wherein the faster the speed is, the higher the cooling efficiency is, the higher the temperature of the casing is, and the faster the rotating speed of the water pump 130 is.
In the system operation process, when the circulating liquid temperature detection module 200 detects that the circulating liquid temperature in the water tank 100 exceeds the available threshold value, the display 250 can display a replacement prompt to remind a user to replace the circulating liquid, the PLC 260 can control the drain valve 170 to open and discharge the circulating liquid, new circulating liquid can be added from the cover plate 270 of the water tank 100 manually, and when the added circulating liquid reaches the position of the liquid level detection module 220, the display 250 can display a stop prompt.
The liquid level detection module 220 at the bottom can detect the pressure at the bottom of the water tank 100 in real time, when the pressure exceeds a set threshold, the pressure immediately sends a digital signal to the PLC 260, and meanwhile, the PLC 260 sends a signal to the display 250 to display a warning prompt, and immediately controls the drain valve 170 to open to discharge circulating liquid, so as to prevent the water tank 100 from leaking water due to the excessive pressure at the bottom of the water tank 100.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
