Abstract
The utility model provides a low rotation speed piston type water suction pump which comprises a shell assembly, a piston pump assembly and a driving cam, the upper end of the piston pump assembly is arranged in the shell assembly, and the lower end of the piston pump assembly extends out of the shell assembly; the driving cam is rotatably installed in the shell assembly, a driving guide column is arranged at the end, facing the piston pump assembly, of the driving cam, and a linear guide groove matched with the driving guide column is formed in the piston pump assembly. A driving motor is installed on the side, away from the piston pump assembly, of the shell assembly and is in driving connection with the driving cam. According to the low-rotating-speed piston type water suction pump, the defects that an existing electromagnetic plunger pump is large in flow, unstable in flow and thermal attenuation is caused are overcome.
