The novel collaborative rectification structure pump is a pump whose pistons are driven by linear motors directly to intake and exhaust oil, and the flow direction of oil is regulated with active collaborative rectification. The design of a linear drive motor requires a detailed understanding of the drive force of the pump. Meanwhile the accurate expression of driving force can also lay the foundation for the control of motor pump module. In this article, the driving force of the pump is divided into three parts, one is static pressure, the second is the friction force, flow force is third. This article focuses on the static pressure. An analytical formula for instantaneous pressure is established. The pressure variation curve is drawn. The simulation module of the novel collaborative rectification structure pump is established and the simulation results verified the accuracy of the analytic model.
