The invention discloses a double-cavity plunger pump with long service life. The double-cavity plunger pump comprises a base, wherein a frame is fixedly connected to the bottom of the base, and a driving device is fixedly connected to the top of the base; a left cavity is fixedly connected to the left side, close to the driving device, of the top of the base, a right cavity is fixedly connected tothe right side, close to the driving device, of the top of the base, and the ends, far away from the driving device, of the right cavity and the left cavity communicate with pump bodies; and the outer walls of the pump bodies are fixedly connected with the outer wall of the base, the bottoms of the pump bodies communicate with water inlet pipes, the tops of the pump bodies communicate with wateroutlet pipes, and the outer walls of the pump bodies are movably connected with anti-corrosion blocks through arranged connecting holes. Galvanic cells are formed by zinc blocks inside the arranged anti-corrosion blocks, sucked water and the anti-corrosion blocks, and the pump bodies are protected by consuming the zinc blocks with high activity according to the electrochemical protection principle, so that the pump bodies are prevented from being corroded; and the clamped anti-corrosion blocks are more convenient to replace, so that the effect that the service life of the device is long is achieved.

    本发明公开了一种高寿命的双腔柱塞泵,包括底座,所述底座的底部固定连接有框架,所述底座的顶部固定连接有驱动装置,所述底座的顶部靠近驱动装置的左侧固定连接有左腔室,所述底座的顶部靠近驱动装置的右侧固定连接有右腔室,所述右腔室、左腔室远离驱动装置的一端均连通有泵体,所述泵体的外壁与底座的外壁固定连接,所述泵体的底部连通有进水管,所述泵体的顶部连通有出水管,所述泵体的外壁通过设置的连接孔活动连接有防腐块。通过设置的防腐块内部的锌块与吸入的水以及防腐块形成原电池,根据电化学保护原理,消耗活性高的锌块来对泵体进行保护,防止泵体被腐蚀,且卡接的防腐块更便于更换,以达到装置使用寿命长的效果。
