The invention belongs to the field of pumps, and particularly relates to a double-heat-insulation heat shield system for a high-temperature pump. According to the double-heat-insulation heat shield system for the high-temperature pump provided by the invention, the double-heat-insulation heat shield system is arranged above a water discharge bend pipe, and is mainly formed by ten parts: a heat-insulation half circular disc I, a heat-insulation half circular disc II, a heat-insulation circular disc, an exhaust pipe, a heat shield support, a heat shield lower cover, a drainage device, a heat radiation assembly, a heat shield upper cover and an air inlet pipe. A double-heat-insulation method is adopted for a pump shaft and a pump head, and a brand newly designed heat insulation structure is adopted, so that the components above the pump head of the high-temperature pump are heat-blocked, and a favorable heat shield effect is further achieved on a motor module and a controlling and monitoring module of the high-temperature pump. The double-heat-insulation heat shield system for the high-temperature pump provided by the invention is simple in structure, easy to install, easy to disassemble, and capable of ensuring the long-time reliable operation of the high-temperature pump.
Description
technical field [0001] The invention belongs to the field of pumps, and mainly relates to a double heat insulation heat shielding system for high temperature pumps. Background technique [0002] At present, the demand for industrial pumps is increasing, and industrial pump devices are developing towards large-scale (large capacity, high efficiency, reliability, low noise and automation). However, it is difficult to make breakthroughs in the development of large-scale industrial pumps in China. Partially dependent on imports. The development of high-temperature molten salt pumps and high-temperature heavy metal pumps is the development direction of the domestic pump industry in recent years. The main characteristics of these pumps are large flow and low head. At present, heat shielding is one of the biggest technical problems of high-temperature pumps. The motor module and control and monitoring module of high-temperature pumps are not suitable for working in high-temperatur...
