PUMP HEAD OF DEEP-WELL PUMP

摘要

Provided is a pump head of a deep-well pump, comprising a pump head body (1); the pump head body (1) is provided with a water outlet (11) and a water inlet (12); the pump head body (1) is also provided with a water passageway (13); the two opposite ends of the water passageway (13) are connected to the water outlet (11) and the water inlet (12), respectively; a spacer (8) is provided in the water passageway (13); the spacer (8) is used for blocking the water passageway (13) and narrowing the water passageway (13). By means of arranging the spacer (8), the cross-sectional area when water flows through the spacer is reduced, such that the force of the water column rushing out of the water outlet is greater, thus increasing the head of the water column gushing from the pump head.
