A cooling device for a high temperature pump

Abstract

The invention discloses a cooling device for a high-temperature pump, and relates to the field of structures of high-temperature pumps. The cooling device comprises baffles and connecting blocks, which are integrally arranged outside a hanger bracket of the high-temperature pump; cooling grooves are formed between the baffles and the connecting blocks and between the baffles; the cooling device also comprises a bottom plate arranged outside the hanger bracket of the high-temperature pump; the bottom plate is connected with the connecting blocks through bolts; one end of the bottom plate is provided with a water inlet communicated with the cooling grooves; the other end of the bottom plate is provided with a water outlet communicated with the cooling grooves. A green water cooling system is adopted, and the cooling device is simple in structure, small in size, low in cost and convenient to use; the cooling device is not provided with cooling pipelines, is convenient to maintain, does not require precious cooling water, is convenient to transport, safe, reliable and easy to manufacture, and is suitable for wide promotion.

Description

technical field [0001] The invention relates to the field of construction of high temperature pumps. Background technique [0002] High temperature pumps are widely used in various fields of national defense and national economy such as chemical industry, electric power, medicine and food, metallurgy and mining, textile printing and dyeing, nuclear industry and energy. [0003] Generally, the high temperature pump transmits the temperature to the seal cavity and the bearing cavity through the high temperature medium conveyed, the shaft and the parts connected to the pump body. Since the working temperature of the bearing and mechanical seal is generally required to be below 100 degrees, exceeding this temperature will It needs to be cooled by external means to ensure that the bearings and mechanical seals work normally at a relatively low temperature. The usual method is to use a water cooling system for forced cooling, but most of these methods make the entire system comple...
