気補給装置。A diaphragm that partitions the automatic air supply device main body into a first chamber that communicates with the suction side of the pump and a second chamber that communicates with the inside of the pressure tank; a spring that biases the diaphragm toward the second chamber; an air intake valve that sucks air into the second chamber when the second chamber has a negative pressure; and a level that is inserted into the pressure tank to a predetermined size and communicates the second chamber with the pressure tank. The automatic air replenishment device for a well pump having a pipe includes a float valve chamber that communicates the second chamber with the level pipe, and a float provided between the automatic air replenishment device main body and the level pipe. a valve chamber body; a float valve that is disposed within the float valve chamber and closes a passage to the second chamber when water in the pressure tank is sucked into the float valve chamber through the level pipe; A conduit having the level pipe installed therein and connecting the pressure tank and the float valve chamber main body is provided, a flange at the upper end of the level pipe is formed of an elastic material, and the flange is connected to the float valve chamber body. An automatic air replenishment device for a well pump, characterized in that the space between the duct and the conduit is sealed.
