Abstract
The utility model discloses a high pressure high flow vane oil pump, having multiple holes for oil intake and multiple holes for oil output, which comprises a stator, a rotor, a front cover and a back cover, wherein the stator is provided with a chamber in which the rotor is rotationally arranged, the section of the chamber is at least provided with three arc edges attached with the rotor, the nearby edges of two adjacent arc edges are concaved to the direction far from the rotor, each space between the nearby edges and the rotor forms a suction pressure oil chamber communicating the oil outlets and the oil inlets on the front cover, the positions on the front cover that corresponding to each suction pressure oil chamber is provided with an oil outlet group and an oil inlet group. The high pressure high flow vane oil pump comprises at least three suction pressure oil chambers, to improve the oil intake amount and output amount of hydraulic oil without changing the size of the oil pump and the rotation speed of the rotor, and distribute the suction pressure oil chambers more uniformly to obtain stable operation, improve service life, reduce noise and high working efficiency.
Description
Technical field
The utility model relates to a kind of oil pump, particularly a kind of vane-type oil pump.
Background technique
Existing vane-type oil pump includes stator, rotor, front and rear covers as shown in Figure 1.Stator has the inner chamber of an odd-shaped cross section, and this inner chamber odd-shaped cross section is provided with two arc limits of being close to rotor and two to away from the recessed adjacent side of rotor one side.Space between adjacent side and the rotor has formed the suction pumping cavity of oil inlet hole and oil outlet on the conducting protecgulum.The rotor of circular cross-section is rotatable the setting in bore of stator.Rotor is provided with radial blade groove, be provided with in each blade groove can before and after the blade that slides.When rotor rotates, blade outwards slides owing to action of centrifugal force, its top withstands on inhales on the pumping cavity surface, the inner chamber of odd-shaped cross section is provided with a plurality of blades will inhale the space that pumping cavity is divided into a plurality of sealings, these spaces are along with the rotation and the flexible of blade of rotor constantly circulates in the process that increases and dwindle, thereby the process of pressing oil is inhaled in realization.Existing oil pump stator only is provided with two and inhales pumping cavities, when causing pump start not steadily, technological deficiency such as power is low and oil pressure is inhomogeneous.
The model utility content
The purpose of this utility model is to overcome the prior art defective, provide a kind of and start steadily, oil pressure evenly, the fuel-displaced high pressure high flow capacity vane-type oil pump of porous oil-feed porous of high working efficiency.
In order to realize above purpose, the utility model is by the following technical solutions: the high pressure high flow capacity vane-type oil pump that a kind of porous oil-feed porous is fuel-displaced, include stator, rotor, protecgulum and bonnet, stator is provided with an inner chamber, rotor is located in the inner chamber rotationally, it is characterized in that: described inner chamber cross section is provided with 3 arc limits of being close to rotor at least, adjacent side between adjacent two arc limits is to recessed away from the direction of rotor one side, space between adjacent side and the rotor has formed the suction pumping cavity of oil outlet and oil inlet hole on the conducting protecgulum, inhales the corresponding position of pumping cavity with each on the protecgulum and all is provided with one group of oil outlet and oil inlet hole.
The beneficial effects of the utility model are: the utility model is provided with at least 3 and inhales pumping cavity, inhales the corresponding position of pumping cavity with each on the corresponding protecgulum and all is provided with one group of oil outlet and oil inlet hole.Like this, under oil pump size, the constant situation of rotor speed, just increase the oil inlet quantity and the oil pump capacity of hydraulic oil, inhaled more even that pumping cavity distributes.And inhale that pumping cavity distributes evenly make that the operation of oil pump is more steady, longer service life, noise is lower, working efficiency is higher.
Below in conjunction with accompanying drawing the utility model is described in further detail
