The invention discloses an oil pump. The oil pump comprises a shell, wherein a cavity in the shell is 8-shaped; the inside of the 8-shaped cavity is provided with a first vane wheel and a second vane wheel which are cylindrical and tangent respectively; the first vane wheel is provided with two grooves which are located in the same straight line respectively; the second vane wheel is provided with two convex vanes which are located on the same straight line respectively; the first vane wheel is tangent to the inner wall of the shell; the vanes of the second vane wheel are tangent to the inner wall of the shell; when the first vane wheel and the second vane wheel rotate respectively till one vane of the second vane wheel is meshed with the depth of one groove of the first vane wheel, the inside residual cavity of the shell is divided into two cavities with equal volumes by the second vane wheel; one cavity is connected with an oil outlet, and the other cavity is connected with an oil inlet; when the first vane wheel and the second vane wheel rotate oppositely, the volume of the cavity which is connected with the oil outlet changes shrinks gradually, so that the oil in the cavity forms high-pressure oil and is pumped out of the oil outlet.
Description
technical field [0001] The invention relates to the mechanical field, in particular to an oil pump. Background technique [0002] In order to extrude high-pressure oil from the oil outlet in the inner cavity of the existing oil pump, it is often necessary to install multiple impellers in the cavity of the oil pump, and the more impellers are installed in the cavity of the same volume, the corresponding capacity of oil The volume becomes smaller, so that the amount of oil squeezed out from the oil outlet per unit time will decrease. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned defects in the prior art, and provide an oil pump that can squeeze out high-pressure oil from the oil outlet and squeeze out a large amount of oil from the oil outlet in a unit time. [0004] An oil pump, comprising a housing, the cavity inside the housing is in the shape of an "8", and a cylindrical, tangential first impeller and a second im...
