The invention discloses a self-driven circulating pump. A pump body is provided with a double-acting small oil cylinder, and a single-acting left large oil cylinder and a single-acting right large oilcylinder are arranged at the positions, on the two sides of a double-acting small oil cylinder body, of the pump body; a left cylinder large cavity of the left large oil cylinder and a left cylindersmall cavity of the double-acting small oil cylinder are oppositely arranged to be of a piston rod connection structure, a right cylinder large cavity of the right large oil cylinder and a right cylinder small cavity of the double-acting small oil cylinder are oppositely arranged to be of a piston rod connection structure, and a structure that piston rods of the double-acting small oil cylinder, the left large oil cylinder and the right large oil cylinder are connected into a whole is formed; independent liquid channels are formed through one-way valves on the pump body, and through switchingconnection of a heat collec
