Abstract

The invention belongs to fluid machinery and discloses a motor-driven two-dimensional asymmetric hydraulic two-dimensional plunger pump which comprises a motor module, a cam transmission module and a plunger cylinder module. The plunger cylinder body module comprises an inner cylinder body, an outer cylinder body and a plunger, the inner cylinder body is fixedly inserted into the outer cylinder body, and the plunger is inserted into the inner cylinder body. According to the structural design of the cam transmission module, a rotary single-cam guide rail and a fixed double-roller frame are adopted, a plunger can drive the cam guide rail to rotate, and the cam guide rail drives a piston to move left and right. By means of the arrangement, the size of the whole pump is obviously reduced, the plunger can rotate and reciprocate depending on planar motion, the reliability of the two-dimensional plunger pump is improved, and the two-dimensional plunger pump has the using effects of being small in size, light in weight, simple in manufacturing process and capable of adapting to high pressure.
