Plunger pump, control method of plunger pump and storage medium

The invention provides a plunger pump, a control method of the plunger pump and a storage medium. The plunger pump comprises a pump body, wherein a plunger cavity is formed in the axis of the pump body; a pump head arranged on the pump body, wherein a pump head inner cavity is formed in the pump head; a plunger which is arranged in the plunger cavity and the pump head inner cavity; a sealing mechanism which is arranged between the pump head and the pump body, and is arranged on the peripheral face of the plunger in a sleeving mode; and crystallization push-sweeping rings which are all arranged between the sealing mechanism and the pump body, and the peripheral face of the plunger is sleeved with the crystallization push-sweeping rings. The plunger is sleeved with a plurality of crystallization push-sweeping rings, the plunger sequentially passes through a sealing mechanism and the crystallization push-sweeping rings during liquid suction, after a saline solution seeping from the crystallization push-sweeping
