Embodiment Construction

[0019] The implementation of the present invention will be described below with specific examples.

[0020] Such as figure 1 As shown, the patented cryogenic pump and cryogenic submersible turbine test bench of the present invention includes a storage area, a circulation area, a test area and an exhaust gas treatment area, and a circulation area is set between the test area and the storage area, mainly composed of liquefied natural gas (LNG) Storage tank 1, liquefied petroleum gas (LPG) storage tank 2, liquid nitrogen (LN2) storage tank 3, recovery pump 4, circulation tank 5, cryogenic pump test circuit 6, test pump pool 7, cryogenic submersible turbine test circuit 8 , condenser 9, hot blast stove 10, torch 11, valves V1 ~ V14 and so on. The gas outlet of the circulation tank is connected to the condenser. After being treated by the condenser, the liquid phase returns to the circulation tank, and the gas phase is connected to the torch or hot blast stove. The liquefied natu...

Abstract

The invention relates to a cryogenic pump and low-temperature immersed turbine test device. A novel cryogenic pump and low-temperature immersed turbine test stand comprises a storage area, a circulation area, a testing area and a tail gas treatment area. The circulation area is arranged between the testing area and the storage area, a storage tank is arranged in the storage area, a circulation tank is arranged in the circulation area, a gas outlet of the circulation tank is communicated with a condenser, and after processing by the condenser, a liquid phase condensation outlet is communicated with the circulation tank. A gas phase outlet is connected to a torch or a hot blast heater. A tested pump or a tested turbine is arranged in the testing area. The interior of the storage tank is communicated with the circulation tank through a pipeline, the circulation tank is communicated with the tested pump or the tested turbine through a pipeline, the tested pump or the tested turbine is communicated with the circulation tank through a pipeline, and then a testing loop is formed. The novel cryogenic pump and low-temperature immersed turbine test stand has the advantages of being simple in operation process and easy to operate, and can be reliably operated in the low temperature working environment.

Description

technical field [0001] The patent of the present invention relates to the field of cryogenic pumps, in particular to a performance test bench for cryogenic pumps and cryogenic submersible turbines. [0002] Note: The test media of the cryogenic test bench are liquefied natural gas (LNG), liquefied petroleum gas (LPG), and liquid nitrogen (LN2). Background technique [0003] At present, cryopumps have been widely used in the field of delivery of cryogenic media. Due to the characteristics of low temperature and easy vaporization of cryogenic medium, the working conditions are harsh, so the requirements for pumps conveying such medium are very high. At present, all such medium and large cryogenic pumps in China rely on imports, and are in a state of foreign technology monopoly. As a result, there are problems such as high product prices, and technical support such as installation and maintenance cannot keep up. In China, the applicant is the first domestic manufacturer to de...
