Abstract

A low-voltage anti-condensation self-lubricating molten salt pump comprises a pump body, an insulating coating, a pump wheel, a first electrode, a second electrode, a pump shaft, a cable, a low-voltage power source and a temperature sensor. Insulating coatings are arranged on the surfaces of the pump body, the pump wheel and the pump shaft; two ends of the pump body are respectively provided with a first electrode and a second electrode, and the first electrode and the second electrode are respectively connected with a low-voltage power supply through cables to form a low-voltage insulation heating loop; and the temperature sensor probe is arranged in the pump body, and the low-voltage power supply directly enables the pump body to heat according to signals of the temperature sensor. The low-pressure anti-condensation self-lubricating molten salt pump is simple in structure, safe, reliable, convenient, fast and efficient, and can be preheated in advance and prevent molten salt from being left in the pump door to be solidified and block the molten salt pump in the starting, running and shutdown maintenance process of a molten salt system.

Description

technical field [0001] The invention relates to the field of heat utilization of molten salt energy storage, in particular to a low-pressure anti-condensation self-lubricating molten salt pump. Background technique [0002] Molten salt energy storage technology is one of the effective means to adjust the mismatch between source and load fluctuations, especially in the aspect of adjusting the consumption of renewable energy. During the trough period of load demand, the energy of During the peak period, the stored high-temperature molten salt energy is released to effectively adjust the user load and the imbalance of the energy supply side, which has broad market prospects. [0003] The molten salt pump is the power source for the circulation of the molten salt energy storage system to provide fluid movement. It is one of the core equipment for the safe temperature operation of the molten salt energy storage system. It is mainly used for parameters such as flow and pressure du...
