The Structural improvements of suspended semi submersible vertical turbine pumps

The long axis vertical pump structure belongs to the technical field of suspended semi submersible vertical turbine pumps. It includes a main shaft, which is fitted with a shaft sleeve. A packing box is installed outside the shaft sleeve. The upper end of the packing box and the shaft sleeve are sealed by installing a packing cover. The end face of the packing box is a circular ring structure, and there is a threaded interface at the end face of the packing box. The threaded interface is connected to a water pipe. This technical method discharges the water leaked from the gap between the shaft sleeve and the packing cover during operation to the designated location through the water pipe connected to the packing box, avoiding the water from the upper end of the packing cover from being thrown into the pump room and ensuring the environment of the pump room.

Technical requirements: 1. A long axis vertical suspended semi submersible pump structure, comprising a main shaft, which is sleeved with a shaft sleeve, and a packing box is installed outside the shaft sleeve. The upper end of the packing box and the shaft sleeve are sealed by installing a packing cover. The feature is that the end face of the packing box is a circular ring structure, and a threaded interface is opened at the end face of the packing box, which is connected to a water pipe.
