Description
technical field [0001] The invention relates to a plunger pump, in particular to a cylindrical cam-driven multi-cylinder bidirectional plunger pump. Background technique [0002] At present, plunger pumps have attracted widespread attention due to their high efficiency and widespread application. Piston pumps require high output pressure, large flow, convenient manufacture and maintenance, and small flow and pressure fluctuations. Generally, multi-piston oil pumps driven by cams are used to achieve this. However, some existing designs have the following deficiencies: 1. There is a return mechanism in the contact design between the cam and the piston, which makes the structure complicated and not reliable enough; 2. The cam driving mechanism drives a reciprocating pump, and the utilization of the cam driving mechanism is insufficient , The work efficiency is not high. 3. The cam drive mechanism drives a reciprocating pump in one direction, and its bending strength is require...
