A motor, abearing box and a molten salt tank temperature monitor are arranged on the test table, the molten salt tank is below the test table, supporting bases of a heating pipe, a molten salt pump inserting opening, a liquidometer, an in-tank pressure transmitter, and a molten salt putting opening are arranged on the upper surface of the molten salt tank, and a backflow pipe inlet is formed in the right end; temperature sensor monitoring points and vibration sensor monitoring points are arranged in an inner cavity of the molten salt tank, the pump bucket is arranged in the middle of the test table, a high-temperature molten salt pump is arranged in the middle of the pump bucket, the lower end of the high-temperature molten salt pump is arranged in the molten salt tank, an outlet of the high-temperature molten salt pump is provided with a backflow pipeline, an outlet pressure transmitter is arranged at the upper end of the backflow pipeline, a flowmeter and a flow control valve are arranged at the lower end of the backflow pipeline, and the backflow pipeline communicates with the molten salt tank through the backflow pipe inlet. The high-temperature condition test is achieved, test needs ofmolten salt pump shafts of different types and lengths can be met, and the comprehensive test and evaluation of the molten salt pump performance can be achieved.

Description

technical field [0001] The invention relates to a high-temperature molten salt pump comprehensive test detection device and a test method, belonging to the field of pump test devices. Background technique [0002] The long-axis submerged high-temperature molten salt pump is the key equipment for transporting high-temperature molten salt. Its conveying medium is molten salt medium under high-temperature conditions, and the operating conditions are extremely harsh. Problems such as part temperature and pump body vibration are more prominent. Therefore, the key elements of long-axis submerged high-temperature molten salt pumps are mainly the monitoring of operating performance, temperature of key parts and pump body vibration indicators. [0003] After retrieval, test and numerical simulation of external characteristics and internal flow of molten salt pump (Shao Chunlei et al. Test and numerical simulation of external characteristics and internal flow of molten salt pump[J]. A...

Problems solved by technology

However, this test device can only use water as the medium for PIV test, which cannot meet the test requirements of other media under high temperature conditions, and the same test of valves cannot be completed in this test device, and key indicators such as vibration and noise cannot be monitored. , it is impossible to perform performance tests on high temperature molten salt pumps under high temperature conditions

Therefore, there is not yet a perfect high-temperature condition test bench at home and abroad to test the above performance
