Embodiment Construction
[0026] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings of the embodiments.
[0027] see figure 2 , figure 2 It is a schematic diagram of the structural principle of the spiral cooling cavity of the present invention.
[0028] figure 2 The cooling water indicated by L enters and exits, the circulating water indicated by I enters, and the circulating water indicated by 0 exits. The cooling cavity of the present invention is arranged on the pump cover 3 of the pump, and is formed by welding the screw type sealing cavity 3A and the pump cover 3, and the screw type sealing cavity 3A is processed into a single helical cooling water passage ( Figure 5 As shown), as shown in the figure, the axial stroke of the spiral channel is longer, and the axial length between the spiral seal cavity 3A and the moving ring sleeve in the mechanical seal component 4 is also longer. In actual use, sinc...
