Therefore, the self-oscillation frequency is a variable value, and the influence of resonance is better eliminated or alleviated. When the plunger goes up, the conical traveling valve at the lower end of the plunger is opened, a part of force is the liquid pressure at the lower part, and by connecting the cylindrical helical compression springs with unequal pitches, the conical traveling valve can be opened more quickly, so that liquid can enter the plunger more quickly, and the efficiency is improved. When the plunger goes down, the cone-shaped traveling valve at the lower end of the plunger is closed, a part of force is the gravity of the cone-shaped traveling valve and the piston principle of the oil pump, and by connecting the unequal-pitch cylindrical helical compression springs, the cone-shaped traveling valve can be closed more quickly and enter the next stroke more quickly. Meanwhile, as the self-vibration frequency of the compression spring is a variable value, the compression spring has better effect of eliminating or relieving resonance, is in dynamic balance in the whole process in one stroke, and improves the liquid yield while protecting the plunger.
