Abstract

The invention discloses a shielding suspension type pump which comprises a delivery pump, a driving motor, a suspension supporting shielding pipe, a supporting plate, a cooling system, a lubricating oil pressurization and delivery device and a sealing filler pressurization and delivery device. The shielding suspension type pump is characterized in that a flange at the upper end of the suspension supporting shielding pipe is fixed on a supporting plate and the delivery pump is fixed on a flange at the lower end of the suspension supporting shielding pipe. The invention has very high vacuum height of suction and hydraulic efficiency, reduces the loss of transmission power of the transmission shaft, improves the efficiency and eliminates the pump shaft abrasion of the long-shaft pump, the broken shaft type fault masking adopts the suspension supporting shielding pipe, the driving motor and the delivery pump are fixed and a forced ventilation system is configured, so that the shielding suspension type pump can normally run under the harsh environment with high temperature and humidity.

Description

Technical field: [0001] The patent of the present invention relates to a pump, in particular to a lift pump in which a pump and a driving machine are suspended on a high-temperature and high-humidity underground liquid surface to lift high-temperature water. Background technique: [0002] In the iron and steel production process of iron and steel production enterprises, there is such a working condition: the scrap steel slag produced by melting iron and steel is immersed in water to cool down. The process water (hereinafter referred to as the medium) contains many minerals and solid particles in the steel slag, and the heat energy exchange of the steel slag makes the medium temperature as high as 80-90°C. (vapor pressure 355-525.6mm / Hg) the medium flows to the storage well (pool) (-4--6 meters), and then the medium is sent back to the slag pool by the lifting pump installed in the well. At present, the lifting pumps commonly used in this working condition are mainly long-ax...
