Description

Technical Field

[0001] The present invention belongs to the technical field related to circulating pumps, and in particular relates to a high-temperature circulating pump with sealing and cooling functions. Background Art

[0002] A circulating pump refers to a pump used to transport circulating liquid for reaction, absorption, separation, and regeneration of absorption liquid in a device. It has a relatively low head and is only used to overcome the pressure drop in the circulation system. A low-head pump can be used. A circulating pump refers to the function of the pump, and a centrifugal pump refers to the structure of the pump. The two are completely two different concepts. The working principle of a circulating pump is that the pump used to circulate water is called a circulating pump. For example, the hot water in the water heating pipe is circulated by a circulating pump.

[0003] After searching, the applicant found a Chinese invention patent entitled "A Slurry Circulation Pump Cooling Device" with a patent publication number of CN114838003A. The device is provided with an alarm component. When the temperature sensor detects that the temperature inside the box body is high, it will transmit a signal to the operation panel. After receiving the signal, the operation panel will start the electromagnet block, so that the electromagnet block is energized and generates magnetism, and then the first magnetic block can be adsorbed. The movement of the first magnetic block drives the resistance block to move and stretches the reset first spring, so that the resistance block triggers the trigger switch. After the trigger switch is triggered, it will start the alarm, so that the alarm sounds an alarm to remind the surrounding staff that the temperature inside the box body is high and the coolant needs to be added again, so that the coolant can cool the air all the time and improve the cooling effect of the circulation pump; however, when the above device is actually used, there are some shortcomings.
