New Description: [New Technology Area] This is a water-cooled low-abrasive pump, especially a pump that reduces wear and provides good heat dissipation. [Prior Art] ... η ---: ... _1 - . As shown in FIG. 5, the prior pump includes a casing 9 〇 'the inside of the casing 90 is formed with a first chamber 91 ' and the casing go A water inlet 92 and a water outlet 93 are provided. The water inlet 92 and the water outlet 93 are connected to the first, and the valley is 91'. The housing 90 is provided with a motor spindle 94. The motor spindle 94 extends into the first The chamber 91 is provided with an impeller 95 which is controlled by the motor 97 and is of value in the first chamber 91. The motor spindle 94 is provided with a liquid-contacting shaft seal 96 and a waterproof gasket adjacent to the first chamber 91. The chamber 91 is prevented from flowing outside the first chamber 91, causing the pump to drain or damage. In the above, after the motor 97 is activated, the motor spindle 94 drives the impeller 95 to rotate. The water is attracted by the centrifugal vortex generated by the rotation of the impeller 95. The water sucked as shown in FIG. 6 enters the first chamber 91 through the water inlet 92. Then, it is discharged from the water outlet 93. The discharged water is subjected to the centrifugal vortex generated by the operation of the impeller 95, so that the water in the first chamber 91 is subjected to a certain pressure, and the water is sent out to the destination by the water outlet 93. The wetted side shaft seal 96 on the motor spindle 94 is squeezed with the gasket to create a gap, causing the water to "inject" to prevent the shaft seal 96 from being squeezed to create a gap, and the shaft seal 96 is urged to the motor spindle 94. In addition, the waterproof function is improved by increasing the tightness. However, the shaft seal 96 fits snugly on the motor spindle 94, and the resulting 丄 丄 丄 oz gap causes hydraulic pressure to escape, which cannot effectively solve the pump discharge, and because of the large hydraulic pressure, it is still easy to push out the pump loss. S, so there is still waterproof performance, pressure water seepage problem.
