Abstract

The invention provides a pump self sealing water device which comprises a pump body, a machine seal water inlet and a sealing water pipeline. An integrated machine seal box is fixed to the right sideof the pump body, and a machine seal water taking opening is arranged above the machine seal water inlet. A heat exchanger is connected to the right side of the sealing water pipeline. A sealing watertaking pipeline is installed above the heat exchanger. An anticorrosive coating is arranged on the outer surface of the pump body. By means of the self sealing water device, the integrated machine seal box is installed on the pump body, the integrated machine seal box is provided with the machine seal water inlet and the machine seal water taking opening, water of the machine seal water inlet isfrom the heat exchanger, the heat exchanger is used for cooling circulating water, the machine seal water taking opening is closed and isolated through a valve, sealing water is taken from the a sub-line pipeline of a pump outlet pipeline check valve, and the sealing water enters the heat exchanger and enters the integrated machine seal box to seal a pump rotating bearing. The pump self sealing water device is simple in structural design and convenient to install and use.

Description

technical field [0001] The invention relates to the field of coal chemical industry and power generation production equipment, in particular to a pump self-sealing water device. Background technique [0002] According to the requirements of coal chemical industry and power generation process, the pulverized coal gasifier of Aerospace Furnace adopts the structure of closed coil water-cooled wall radiation chamber, and the boiler circulating water is pressurized and sent into the water-cooled wall coil of the gasifier through the medium-pressure boiler circulating water pump. It is divided into three parts, namely the slag mouth coil, the top coil and the main coil. The coil adopts a four-inlet and four-outlet structure to ensure uniform distribution of flow resistance in the tube side, maintain a large flow of forced water circulation in the water-cooled wall coil, and the water absorption furnace flowing in the tube After the internal gasification reaction heat is partially ...
