The flywheel is widely used in forging machinery with impact load. The newly developed forging equipment gas-liquid screw press also adopts the flywheel drag system, and the motor directly drives the oil pump with the flywheel. For the general forging machinery drive system, people have already done a lot of research. The purpose of this paper is to propose a method suitable for the calculation of the parameters of the gas-liquid screw press drag system, to solve the problem of reasonable matching of parameters, to improve its power system. Design calculation methods. Dragging the system motion equation to solve the motion equation of the drag system is the core of the drag problem. In order to drag the system torque for the motor synchronous speed for the time, the motor slip rate is the motor's critical slip rate for the motor's maximum electromagnetic torque, for the drag system load torque. In general, the system load lining is a function of time, and the equation is not easy to solve by analytical methods. If the parameters such as the motor flywheel are unknown, the numerical solution of the equation is also difficult to find. For this reason, the mechanical characteristics of the motor are often linearized for simplification, but in the flywheel-driven system, due to large load changes, the motor does not operate in the rated area, and the mechanical properties are linearly processed in the overloaded area. There is a big difference from the actual situation. The impact load of the mechanical work with impact load is short, so in general, the average value can be used instead, and the load is regarded as a constant. The variation law of the load torque and the motor output torque of the drag system can be expressed. For the impact load torque, the impact load is the no-load torque, and the dead time is the maximum duty of the motor output torque. Through the test of the relevant quantity during the working process of the gas-liquid screw press, the load of the gas-liquid press is regarded as a constant to discuss the drag problem.
