Macro-axis submerged high-temperature molten salt pump comprehensive test detection device

Abstract

The invention relates to a comprehensive test and detection device for a long-axis submerged high-temperature molten salt pump, which includes a test pump and a molten salt tank. The test pump is located in the molten salt tank, and a circuit pipe inlet is opened on the molten salt tank. The output port of the test pump is connected with the inlet of the circuit pipe through a circuit pipe; a pressure gauge, a flow meter, a check valve, a flow regulating valve and a maintenance valve are installed on the circuit pipe; Installed with pressure gauge and liquid level gauge. The invention realizes the test under high temperature conditions, and combines the pump test device with the valve test device, saves the space occupied by the device and the energy consumption of operation, unifies the test conditions of molten salt pumps and valves with the working conditions, and provides accurate pump and valve performance under multi-high temperature conditions. evaluation of. Set up monitoring sensors at key parts to monitor the operation stability of the test device and the equipment under test, and combine the performance evaluation results to evaluate the operation stability of the test object and ensure the safe operation of the test equipment.

Description

technical field [0001] The invention relates to a high-temperature molten salt pump test device, which belongs to the technical 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 in solar thermal power generation systems. Its transport medium is molten salt under high-temperature conditions, and the operating conditions are extremely harsh. The operating performance, temperature of key parts, pump body vibration, noise and other problems are more prominent. Therefore, the key to the long-axis submerged high temperature molten salt pump is the monitoring of operating performance, temperature of key parts, pump body vibration, and noise indicators. At present, there is no perfect high-temperature condition test bench at home and abroad to test the above performance. [0003] After retrieval, test and numerical simulation of external characteristi...

Problems solved by technology

However, this test device can only use water as the medium for PIV test, which cannot meet the test requirements under high temperature conditions. Moreover, the same test of valves cannot be completed in this test device, and key indicators such as vibration and noise cannot be monitored.
