Referring to fig. 9 and 10, which are a schematic and functional diagram, respectively, of the assembly of the apparatus of the present invention to a bearing housing of a microtome, the method of using the apparatus of the present invention to adjust the temperature of the bearing housing is as follows:

(1) the antifreeze is output to the heat exchanger 21 by the water pump 11, and the opening degree of the motor valve DN40 is set so that the temperature of the antifreeze output from the heat exchanger 21 is X (the optimal value of the antifreeze output from the heat exchanger is 20 ℃).

The DN40 motor valve only participates in the control of a 'total temperature sensor', and the sensing temperature of the 'total temperature sensor' is the temperature of the antifreeze liquid output from the heat exchanger 21. The "total temperature sensor" temperature is controlled at X by controlling the flow of plant cooling water into the heat exchanger 21.

(2) The temperature Y of the temperature sensors 1, 2, 3 and 4 is set, and the temperature value is larger than X. (the temperature Y in this example is preferably 22 to 23 ℃ C.)

(3) The equipment starts to operate, and antifreeze at the temperature of X ℃ enters the bearing box 1, the bearing box 2, the bearing box 3 and the bearing box 4 through the motor valve 1, the motor valve 2, the motor valve 3 and the motor valve 4 respectively. The opening degree of the 4-way motor valve is kept at 100% in the first 10 minutes of the operation of the bearing box; after 10 minutes of operation, the temperature sensors 1, 2, 3 and 4 feed back the temperature, and the temperature fed back by each temperature sensor is the temperature of each bearing box.

(4) When the temperatures fed back by the temperature sensors 1, 2, 3 and 4 are different, the motor valves 1, 2, 3 and 4 are adjusted to different opening degrees, so as to control the flow rate of the antifreeze solution passing through the bearing box. The opening degree of the 4-way motor valve in the embodiment is between 35% and 100%.

The anti-freezing solutions with different flow rates have different cooling effects on each bearing box, so that the final feedback temperatures of the temperature sensor 1, the temperature sensor 2, the temperature sensor 3 and the temperature sensor 4 are basically consistent, and the rotation process of each bearing box is maintained under the basically consistent temperature condition.

The present invention has been described in detail, and it should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
