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...

Abstract

The invention belongs to the technical field of power plants, and especially relates to an energy-saving oil pump. The invention solves the technical problems of unreasonable design in the prior art. The energy-saving oil pump of the invention comprises a pump body and a pump cover which are buckled together with each other; a cylindrical stator is fixed on the inner wall of the pump cover; a rotor is disposed in the stator; the rotor sleeves a rotor shaft; one end of the rotor shaft is rotatably connected with the pump cover, and the other end penetrates the pump body and extends to the outside of the pump body; an oil inlet and an oil outlet are disposed on the pump body; the oil pump is characterized in that an oil channel surrounding the periphery of the rotor is disposed between junction surfaces of the pump body and the pump cover. Compared with the prior art, the energy-saving oil pump has the following advantages of: 1. reasonable design, simple structure, high mechanical strength, easy processing manufacturing, and low production cost; 2. stable oil pressure, unobstructed oil path, good tightness, and rare leakage; 3. rare precision loss during transport process; 4. energy saving, and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of power devices, and in particular relates to an energy-saving oil pump. Background technique [0002] Oil pumps are composed of pump body, stator, rotor and other parts, and are widely used in various industries. The existing oil pump has high manufacturing cost, great assembly difficulty, unsatisfactory sealing performance and low mechanical strength. For this reason, people have carried out long-term exploration, put forward various solutions. [0003] For example, Chinese patent literature discloses an improved diesel engine oil pump [Patent No.: 200420091807.2], its basic structure includes: a pump casing, a rotor slidingly fitted with the inner cavity of the pump casing, and an eccentric arrangement on the inner cavity of the rotor to engage with the inner cavity of the rotor The rotating core and the mandrel matched with the central hole of the rotating core are characterized in that: the mandrel i...
