Abstract

The invention discloses a multi-level combined pump and belongs to the technical field of pumps. The traditional piston pump has a defect that liquid cannot be conveyed in a high-lift way. The multi-level combined pump comprises at least two piston pumps, a gear box, a gear transmission mechanism and a power main shaft serving as a power input shaft, wherein the water inlets of the two adjacent piston pumps are connected in series with the water outlets of the two adjacent piston pumps through a connection flange; the gear box is fixedly connected with the piston pumps; the power main shaft is arranged on the gear box through a bearing, and one end of the power main shaft extends out of the gear box; and the power main shaft is in transmission connection with the driving shaft of each piston pump through the gear transmission mechanism arranged in the gear box. The multi-level combined pump has a small volume and a simple structure and can convey the liquid in the high-lift way.

Description

technical field [0001] The invention belongs to the technical field of pumps, and in particular relates to a multi-stage combined pump. Background technique [0002] Patent No. 200520115790.4 discloses a combined multi-section cam-piston pump. This pump has high suction and discharge efficiency and self-priming capability, and has bidirectional suction and discharge functions. However, this pump cannot transport liquid with a high head. However, the high-lift liquid pumps on the market, such as centrifugal pumps and plunger pumps, have complex structures, large volumes, poor self-priming capabilities, and relatively low suction and discharge efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that existing piston pumps cannot transport liquid with high lift, and provide a multi-stage combination pump with small volume, simple structure and high lift liquid delivery. For this reason, the present invention adopts fol...
