Detailed Description

All of the features disclosed in this specification, or all of the steps in a method or process disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.

As shown in fig. 1-2, a piston type slurry pump in the form of a parallel conveying cylinder of the present utility model includes a conveying cylinder I7, a conveying cylinder ii 8, an oil cylinder I9, an oil cylinder ii 10, a buffer tank 12, and a base 14;

One end of the conveying cylinder I7 is connected with the oil cylinder I9, one end of the conveying cylinder II 8 is connected with the oil cylinder II 10, and the conveying cylinders I7 are integrally arranged on the base 14 in parallel in pairs; the buffer tank 12 is connected with one end of the discharging pipe 2 and is fixed on the base 14; the oil station 11 is mounted on a base 14, and the electric cabinet 13 is attached to the oil station 11.
