Embodiment Construction
[0019] like figure 1 As shown, the energy-saving oil pump includes a pump body 1 and a pump cover 2 that are interlocked with each other. A cylindrical stator 3 is fixed on the inner wall of the pump cover 2, and a rotor 4 is arranged inside the stator 3. The rotor 4 is sleeved on the rotor On the shaft 5 , one end of the rotor shaft 5 is rotationally connected with the pump cover 2 , and the other end passes through the pump body 1 and extends out of the pump body 1 . The pump body 1 is provided with an oil inlet hole 11 and an oil outlet hole 12 , and an oil passage around the periphery of the rotor 4 is provided between the joint surface of the pump body 1 and the pump cover 2 . The shape of the state-owned channel here is similar to the peripheral shape of the pulley drive structure.
[0020] like Figure 5 As shown, the outer end of the pump cover 2 is provided with reinforcing ribs 21 arranged along the edge, and the reinforcing ribs 21 are connected with the pump cove...
