Axial force self-balancing magnetic force driving pipeline pump

The utility model provides an axial force self-balancing magnetic force driving pipeline pump. The axial force self-balancing magnetic force driving pipeline pump comprises an upper balancing disk (3) mounted on a pump shaft (6), and a lower balancing disk (4) mounted on a bearing sleeve (7). A pressure chamber (3-4) is formed among the upper balancing disk (3), the lower balancing disk (4) and a sliding bearing (5), the pressure chamber (3-4) is provided with a pressure chamber entrance (4-1) which is communicated with a pump cover inner cavity, and the pressure chamber (3-4) is further communicated with an inner cavity of a separating sleeve (1) through an end face clearance (14) between the upper balancing disk (3) and the lower balancing disk (4). By means of the axial force self-balancing magnetic force driving pipeline pump, dynamic balance of the axial force is achieved, and thrust bearings on two side end faces are enabled not to contact with each other basically and be abraded.
