Quickly detached stable spindle mounting seat for axial flow pump

Abstract

The invention discloses a quickly detached stable spindle mounting seat for am axial flow pump. The quickly detached stable spindle mounting seat for the axial flow pump comprises a substrate, a top guide bearing, a packing box and a packing gland, wherein the top guide bearing is arranged on the inner wall of the substrate and is fixedly connected through a side bolt; a bent arm is arranged at one side end of the packing box; the bent arm is connected to the side wall of the substrate through a bolt; the bent arm of the packing box and the side wall of the top guide bearing form a sealed space; an export opening is also formed in the bent arm; at least one sealed packing ring is arranged between the packing box and a spindle; and the other side end of the packing box is connected to the packing gland through a bolt to form a seal. The quickly detached stable spindle mounting seat for the axial flow pump disclosed by the invention has the characteristics of being simple in structure and convenient to mount and detach, and has stable supporting and sealing effects to the spindle of the axial flow pump.

Description

technical field [0001] The invention mainly relates to the mounting seat of the main shaft of the axial flow pump. Background technique [0002] Axial flow pumps are large-scale water conservancy equipment, mainly used for farmland irrigation and water conservancy transportation. The existing axial flow pumps for water conservancy transportation equipment inevitably have machining errors and installation errors in the process of production, processing and installation. Long-term operation will cause the pump shaft and impeller equipment to run unbalanced, thereby accelerating the wear of the axial flow pump and reducing the water consumption. flow delivery efficiency. At the same time, due to the high-speed rotation of the impeller, the operating condition of the impeller shaft is relatively harsh, and the problem of eccentricity and non-parallel is prone to occur, resulting in a decrease in the efficiency of the axial flow pump. In addition, the installation of the traditi...

Problems solved by technology

The existing axial flow pumps for water conservancy transportation equipment inevitably have machining errors and installation errors in the process of production, processing and installation. Long-term operation will cause the pump shaft and impeller equipment to run unbalanced, thereby accelerating the wear of the axial flow pump and reducing the water consumption. Flow Delivery Efficiency

At the same time, due to the high-speed rotation of the impeller, the operating condition of the impeller shaft is relatively harsh, and the problem of eccentricity and non-parallel is prone to occur, resulting in a decrease in the efficiency of the axial flow pump. In addition, the installation of the traditional axial flow pump shaft needs to be installed and adjusted on both sides of the water pipe. Due to the operation Space limitation results in inefficient installation and disassembly
