Vertical pipeline desulfurization pump for ship

Abstract

The invention discloses a vertical pipeline desulfurization pump for a ship. The vertical pipeline desulfurization pump comprises a pump body, a pump cover packaged at the upper end of the pump body,an impeller arranged in an inner cavity of the pump body, a pump shaft with the front end and impeller fixing rear end penetrating out of the pump cover, a motor support and a motor, wherein the motorsupport and the motor are fixed above the pump body. A mechanical seal is arranged at the joint of the pump body and the pump cover. The fixing position of the bottom of the motor support and the upper end of the pump body avoids the packaging position of the pump cover. A disassembly window is formed in the lateral direction of the motor support. The motor is fixed above the motor support. The upper end of the pump shaft is connected with an output shaft of the motor through a coupling. The pipeline pump is used for a desulfurization station for the ship and has high efficiency, long servicelife and convenient maintenance.

Description

Technical field [0001] The invention relates to a marine vertical pipeline desulfurization pump, which belongs to the field of pipeline pumps. Background technique [0002] The pipeline pump is a kind of single-stage single-suction or multi-stage centrifugal pump. It is a vertical structure. Because its inlet and outlet are on the same straight line, and the shaft center is on the same plane, and most of the inlet and outlet have the same caliber, it can be easily installed in The middle of the transportation pipeline is used as a booster pump, which is widely used. When disassembling and overhauling conventional pipeline pumps, the entire pump needs to be disassembled for overhaul and maintenance. There are abundant resources on land and ample space. The whole pump is more convenient for disassembly, assembly and maintenance, and various resources on board are limited. Generally, pipeline pumps circulate the flushing fluid without sealing, and only rely on the back pressure of...

AI Technical Summary

Problems solved by technology

In general pipeline pumps, sealless flushing fluid is circulated, and the flushing and cooling only rely on the back pressure of the impeller higher than the pressure of the mechanical seal cavity, the cooling effect is not sufficient, or the external flushing water is used for mechanical seal flushing

The inlet of a conventional pipeline pump is generally an elbow structure, the inlet and outlet are on the same plane as the center of the rotor, the flow capacity of the medium is not high, the structure is simple but the efficiency is generally not high

The impeller adopts the nut locking method, and the thread on the shaft end surface is exposed in the medium, which is not conducive to the flow of the medium
