Vertical non withdrawable suspended semi submersible vertical turbine pump exhaust system

The exhaust system of a vertical non withdrawable suspended semi submersible vertical turbine pump includes a discharge elbow (1) and a packing box body (2) installed at the upper end of the discharge elbow (1). An exhaust pipe (4) is connected to the packing box body (2). The outlet end of the exhaust pipe (4) bends towards the lower flange of the discharge elbow (1) and leads to the suction water tank. Weld a pipe joint (3) at the packing box body (2), and connect the exhaust pipe (4) to the pipe joint (3). This technical method is a vertical non withdrawable suspended semi submersible vertical turbine pump exhaust system that can quickly exhaust the air inside the pump body and protect the packing and upper bearings from burning out.

Technical requirements: 1. A vertical non withdrawable suspended semi submersible vertical turbine pump exhaust system, comprising a discharge elbow (1) and a packing box body (2) installed at the upper end of the discharge elbow (1), characterized in that an exhaust pipe (4) is connected to the packing box body (2).
