Abstract

The invention provides a self-sealing water device for a machine pump, which includes a machine pump body, a machine seal water inlet and a seal water pipeline. A cartridge type machine seal box is fixed on the right side of the machine pump body. An organic sealed water intake is arranged above, a heat exchanger is connected to the right side of the sealed water pipeline, a sealed water intake pipeline is installed above the heat exchanger, and an anti-corrosion coating is placed on the outer surface of the pump body. The machine pump self-sealing water device provided by the present invention is installed on the pump body through a packaged machine seal box. Heater, the heat exchanger uses circulating water for cooling and cooling, the water intake of the machine-sealed water is closed and isolated by a valve, and the sealing water is taken from the pump outlet pipeline check valve auxiliary line pipeline, and the sealing water enters The heat exchanger enters the assembly-type machine sealing box to seal the rotating bearing of the machine pump. The invention has simple structural design and is 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 ...
