Referring to fig. 1 and 2, in a specific embodiment, water used by the water-cooled motor 1 comes from the pump body 2, and since the water pressure at the outlet flange 3 of the pump is high, in order to avoid damaging the cooling cavity of the water-cooled motor 1, the water led out from the outlet flange 3 of the pump needs to be decompressed, so that a decompressing component is arranged on the water inlet pipe, wherein the decompressing component is arranged close to the outlet flange 3 of the pump. In a particular embodiment, the pressure relief feature includes a first flange 12 and a second flange 13 disposed on the inlet pipe and a plurality of pressure relief orifice plates 14 (e.g., 3 pressure relief orifice plates 14) disposed between the first flange 12 and the second flange 13; wherein possess a plurality of little through-holes on the decompression orifice plate 14, a plurality of decompression orifice plates 14 staggered arrangement are in the same place, and the resistance that multiplicable rivers passed through realizes the decompression effect, and the pressure differential around a plurality of decompression orifice plates 14 is calculated and is tested, ensures that the pressure of motor cooling chamber water inlet 8 department is a little higher than the pressure of pump import flange 4 department to guarantee that rivers can the circulatory flow.
