Embodiment 1

[0022] Such as figure 2 As shown, two opposite first equidistant vanes 4 and two opposite second equidistant vanes 5 form upper, lower, left and right four cavities in the casing 1, and the upper end of the upper cavity is a liquid inlet 15 , the lower end of the lower cavity is the liquid outlet 16, the mandrel rotates counterclockwise, the space of the upper cavity becomes larger, and the liquid is sucked in; the space of the lower cavity becomes smaller, and the liquid is pressed out; the space of the right cavity becomes larger, as the The mandrel rotates counterclockwise, the right cavity communicates with the liquid inlet 15, and the right cavity sucks liquid; the space of the left cavity becomes smaller, and as the mandrel rotates counterclockwise, the left cavity communicates with the liquid outlet 16, and the left cavity The body presses out the liquid; the cycle repeats to realize the function of the isometric vane pump.

Embodiment 2

[0024] Such as figure 2 As shown, two opposite first equidistant vanes 4 and two opposite second equidistant vanes 5 form upper, lower, left and right cavities in the housing 1, and the upper end of the upper cavity is a liquid inlet 15 , the lower end of the lower chamber is the liquid outlet 16. When the liquid inlet 15 is continuously injected with high-pressure liquid, the space of the upper chamber is forced to become larger, and the mandrel rotates counterclockwise; as the mandrel rotates counterclockwise, the left chamber and the liquid outlet 16 is connected to press out the liquid; as the mandrel rotates counterclockwise, the right cavity communicates with the liquid inlet 15, and the right cavity sucks liquid, forcing the space of the right cavity to become larger. The function of the vane motor.

Abstract

The invention discloses an equidistant vane pump / motor, and belongs to the technical field of pumps / motors. The equidistant vane pump / motor comprises a shell, end covers, a mandrel, first equidistantvanes and second equidistant vanes. End covers are arranged at two ends of the shell; the mandrel is arranged in the shell; two ends of the mandrel are rotatably connected with the end covers; the twoopposite first equidistant vanes and two opposite second equidistant vanes are arranged on the mandrel in the radial direction; the radial widths of the two opposite first equidistant vanes and the two opposite second equidistant vanes are equal; and two sides of the two opposite first equidistant vanes and the two opposite second equidistant vanes are attached to the inner wall of the shell. Theequidistant vane pump / motor provided by the invention is simpler in structure, the problem that the contact between the vanes and the shell is not tight enough is solved, and the working efficiency is higher.

Description

technical field [0001] The invention relates to an equidistant vane pump / motor, which belongs to the technical field of pumps / motors. Background technique [0002] At present, the traditional vane pump keeps contact with the inner wall of the cylinder by the centrifugal force generated by the vane itself when it rotates, or keeps the vane in contact with the inner wall of the pump by spring support. The disadvantage is that the contact is not tight enough and the working pressure of the pump body is not high. . The traditional vane motor relies on spring support to keep the vane in contact with the inner wall of the pump. The disadvantage is that the contact is not tight enough, and the working pressure of the motor is not high, especially when the speed is low. Contents of the invention [0003] In order to solve the shortcomings of the above-mentioned prior art, the present invention provides an equidistant vane pump / motor, which has a simpler structure, solves the prob...
