Dynamic Performance Analysis of Bias Large Flow High-pressure Reciprocating Pump

Basing on the basic principle of the machine movement, the movement and dynamic performance analysis of bias large flow high-pressure reciprocating pump are done. The location, velocity distribution and acceleration of the multi-cylinder are listed. Thus, the calculation model of the equivalent resistance torque is simplified according to the device operating characteristics. So the equivalent torque and equivalent power on the crankshaft are gotten. These data are the basic data for the design and stability analysis of power system.
