Abstract
A pneumatic diaphragm pump used in coal mine consists of two symmetric shells whose superior parts are connected by valve body, the middle parts of the shells are connected by core shaft and the core shaft is penetrated by a splint and a diaphragm which divides the shell into an air cavity and a water cavity. The lower part of the water cavity is communicated with water inlet components and water outlet components, the pump is characterized in that a vertical directional-control valve is arranged in the top part of the valve body, a transverse shaft hole is provided in the inferior part thereof, and an air inlet and an air outlet which are equipped with handles are arranged on the top of the valve body. The inlet components and the outlet components comprise tee pipes, elbows, valve plates and location-limited plates. The utility model powered by compressed air can produce a pressure difference in the cavity by reversible airflow in the air reversing valve to drive the diaphragm in the pump chamber to do reciprocating motion so as to realize the function of suction and discharge medium. The pump is suitable for underground drainage in coal mine in particular.
