1. An automatic system for disassembly and assembly of plunger pumps, comprising:
a plurality of working members, comprising a rotary puller, a lever, and at least one gripper;
a first robotic arm, comprising a working end and a connection end opposite to the working end, wherein the working end of the first robotic arm is configured to be detachably connectable with each of the plurality of working members;
a first driver, connected with the connection end of the first robotic arm and configured to drive the first robotic arm to move in a three-dimensional space;
a second driver, configured to drive the plurality of working members connected with the working end;
a plunger pump for disassembly or assembly, wherein the plunger pump comprises a hydraulic end having a first cavity and a plurality of first function components disposed in the first cavity;
a control system, communicatively connected with the first driver and the second driver; and
a detector, configured to acquire an operation state of the first function components and determine whether at least one of the first function components needs to be disassembled according to the operation state,
wherein in response to determining that the at least one of the first function components needs to be disassembled, the control system is configured to control the first driver to drive the first robotic arm to move in an extension direction of the first cavity, and to control the first robotic arm to drive at least one of the working members to enter the first cavity and be in matched connection with the at least one of the first function components in the first cavity, so as to disassemble the at least one of the first function components in the first cavity.
