[0019] In actual production, because the temperature of the cooling water in the cooling water tank 1 is 30°C, when the remote temperature sensor detects that the temperature in the mechanical seal 53 is higher than 55°C, the automatic control system starts the water pump 2, the regulating valve 3 and the flow meter 4 to input cooling water to the mechanical seal 53 for cooling; when the remote temperature sensor detects that the temperature in the mechanical seal 53 is lower than 45°C, the automatic control system controls the regulating valve 3 and the flow meter 4 to close or reduce the flow of cooling water; then, by controlling the flow of cooling water, the temperature in the mechanical seal 53 is always kept between 45 and 55°C, thereby achieving the purpose of cooling the mechanical seal 53.
