In order to solve the problems in the prior art, the applicant has conducted in-depth analysis on various existing schemes, which are specifically as follows:
temperature detection is one of important control parameters for protecting the safe operation of the centrifugal vapor compressor, and a thermal resistor is a commonly used temperature measuring element. The temperature detection mode generally adopts the mode that a thermal resistor is directly inserted into a temperature measuring hole and has enough insertion depth. The thermal resistor is fixed in length, when the temperature measuring position is not ideal, the distance of a temperature measuring point is far away, the length of the thermal resistor is insufficient, and the implementation of temperature measurement is influenced.
To this end, the applicant proposes the following solution, and as shown in fig. 1 to 2, the present embodiment provides a centrifugal vapor compressor with temperature measurement protection, which includes a centrifugal vapor compressor (hereinafter referred to as a compressor) having a temperature measurement hole, and a temperature measurement mechanism for inserting the temperature measurement hole. The temperature measuring mechanism comprises a first shell 10, a second shell 11, a temperature measuring piece 12, a pushing piece 13 and a positioning piece 14. The first casing 10 is hollow and has sliding grooves on its inner walls.
The second housing 11 is slidably connected to the inner wall of the first housing 10, and the second housing 11 can move along the length direction of the inner wall of the first housing 10. And the outer walls of the two sides of the second shell 11 are respectively provided with a sliding strip 16, and the sliding strips 16 are in adaptive connection with the sliding grooves, so that the sliding connection of the second shell 11 along the inner wall of the first shell 10 is realized.
The temperature measuring piece 12 is a platinum thermal resistor, and the temperature measuring piece 12 is arranged in the second shell 11; the temperature measuring part 12 comprises a junction box 121 and a guide rod 122 connected with the junction box 121, wherein the guide rod 122 is used for measuring temperature. The guide rod 122 is sleeved with a protective sleeve 19. Two sets of projections 123 are fixedly disposed at one end of the guide rod 122 close to the junction box 121, and each projection 123 has a threaded hole. Mounting holes are formed in both sides of the second housing 11. The bolt 15 penetrates through the mounting hole to be in threaded connection with the protruding block 123, the temperature measuring piece 12 is fixed in the second shell 11, and the temperature measuring piece 12 is detachably connected with the second shell 11 and is convenient to disassemble and replace. The pushing piece 13 is fixedly connected with the top end of the second shell 11; the pusher 13 may be a straight rod or a telescopic rod.
The positioning element 14 is sleeved with the first casing 10 and can slide along the length direction of the outer wall of the first casing 10. The positioning part 14 is a positioning plate with a hollow center, the first housing 10 is located in the hollow center of the positioning plate, the positioning plate is connected to the first housing 10 in a clamping manner, and the positioning plate and the first housing 10 do not move relatively under the action of no large external force. The flexible ring is fixedly arranged at the hollow position in the center of the positioning plate, and when the positioning plate is clamped with the first shell 10, the flexible ring is positioned between the positioning plate and the first shell 10, so that the degree of freedom of movement between the positioning plate and the first shell 10 can be improved by the flexible ring, and the positioning plate can slide on the first shell 10. At least two groups of screws 17 are arranged on the positioning plate. The bottom of the positioning plate is fixedly provided with a flexible pad 18.
