Pipeline centrifugal pump for ship

Abstract

The invention discloses a pipeline centrifugal pump for a ship, comprising a motor and a pump body, wherein a connection plate is arranged at the bottom part of the motor. A motor base is arranged at the upper end of the pump body. A round flange is arranged between the motor base and the connection plate. Both the motor base and the connection plate are connected on the round flange through a bolt. A temperature measuring hole is arranged at one side of the round flange. The temperature measuring hole is integrally provided with a temperature sensor. The temperature measuring hole is also arranged on the pump body and internally provided with the temperature sensor. The periphery of the round flange is welded on a cabin plate when the pump is installed so that the motor is at the upper part of an engine room. The combustion and explosion hazards caused by rise of heat generated from operation of the motor in the engine room are effectively avoided; the round flange and the pump body are provided with the temperature sensor so that the temperature of the motor rotating shaft and the temperature of the pump body can be monitored in real time to more effectively avoid accident.

Description

technical field [0001] The invention relates to a marine vertical centrifugal pump, in particular to a marine pipeline centrifugal pump. Background technique [0002] The engine room of a ship is the centralized installation place of the main and auxiliary engines. Due to the limited area of ​​the engine room, there are strict requirements on the size of the main and auxiliary engines loaded in the engine room. Compared with the marine horizontal centrifugal pump, the marine vertical centrifugal pump is widely used in the water supply and drainage system of the ship because of its small footprint and compact planar structure. The marine pipeline centrifugal pump is one of the marine vertical centrifugal pumps. It is mainly composed of the motor and the pump body. The upper end of the pump body is equipped with a motor base, and the bottom of the motor is equipped with a connecting plate. The connecting plate is connected to the motor base through bolts. In general, marine p...

Problems solved by technology

The above-mentioned installation method of installing the motor in the engine room not only occupies the limited space in the engine room, but also poses serious safety hazards: the narrow engine room space is relatively airtight, and there are usually flammable and explosive oil stains and oily fumes, while The large heat generated by the operation of the motor cannot be dissipated in time, and the temperature in the cabin will continue to rise, which may lead to the danger of combustion and explosion
