Description

Technical Field

[0001] The invention belongs to the technical field of fluid device testing, and in particular relates to a comprehensive performance testing device for a seawater desalination turbine-type energy recovery integrated machine. Background Art

[0002] As an important form of reverse osmosis residual pressure energy recovery device for seawater desalination, the turbine type energy recovery integrated unit (abbreviated as turbine type integrated unit) has the characteristics of simple structure, convenient operation and maintenance, low manufacturing cost and wide application range. The turbine type integrated unit consists of a pump end and a turbine end. The turbine impeller and the pump impeller are connected together through a common shaft, realizing the perfect coupling between the hydraulic turbine and the pump rotor, and directly converting the energy of the high-pressure liquid at the turbine end into the energy of the low-pressure liquid at the pump end, which has a very obvious energy recovery structure advantage.

[0003] At present, the production technology of turbine-type integrated machine is mainly mastered by FEDCO (Fluid Equipment Development Company) and ERI (Energy Recovery) in the United States. In China, only a few units such as Tianjin Seawater Desalination and Comprehensive Utilization Research Institute of the Ministry of Natural Resources and Shijiazhuang Haikuo Jie Neng Technology Co., Ltd. have the structural design, processing and manufacturing technologies of this product. Due to the small number of domestic product research and development, there are basically no test devices for turbine-type integrated machines. Since turbine-type integrated machines involve the pump end and the turbine end, it is also difficult to directly graft the test devices of existing pumps. Therefore, it is necessary to develop a reliable comprehensive performance test device for seawater desalination turbine-type energy recovery integrated machines. Summary of the invention

[0004] The present invention mainly aims at solving the problem that there is no comprehensive performance test device for a seawater desalination turbine type energy recovery integrated machine in the prior art, and provides a comprehensive performance test device for a seawater desalination turbine type energy recovery integrated machine.

[0005] The present invention is implemented by the following technical scheme: a comprehensive performance test device for a seawater desalination turbine energy recovery integrated machine, comprising a water tank, a water inlet pipeline, a water outlet pipeline, and an auxiliary pipeline;

[0006] The turbine-type integrated machine comprises a pump end and a turbine end, one end of the water inlet pipe is connected to the water tank, the other end of the water inlet pipe is connected to the water inlet of the pump end, one end of the water outlet pipe is connected to the water tank, the other end of the water outlet pipe is connected to the water outlet of the turbine end;

[0007] A speed torque sensor and a speed torque meter are installed between the pump end and the turbine end of the turbine-type integrated machine;

[0008] The auxiliary pipeline is composed of a main pipeline and branch pipelines a, b and c. The main pipeline is connected to the water tank, branch pipeline a is connected to the water inlet of the turbine end, branch pipeline b is connected to the water outlet of the pump end, and branch pipeline c is connected to the water inlet pipeline connected to the water inlet of the pump end.

[0009] The water inlet pipeline is provided with a valve, a filter, a flow meter a, a pressure gauge a, a high-pressure pump, a pressure gauge b, and a regulating valve a in sequence starting from the water tank connection end;

[0014] The branch pipe b is provided with a pressure gauge d;

[0015] The branch pipeline c is provided with a regulating valve b, a flow meter b, and a pressure gauge c in sequence starting from the main pipeline connection end;

[0016] The connection interface between the branch pipeline c and the water inlet pipeline is located between the regulating valve b and the flow meter b;

[0017] The speed and torque sensor is used to measure the torque and speed, and the speed and torque meter can display the speed and input power;

[0018] Preferably, the flow meter a is a low-pressure electromagnetic flow meter;

[0019] Preferably, the pressure gauge a, pressure gauge b, pressure gauge c, pressure gauge d, pressure gauge e, and pressure gauge f are shock-resistant precision pressure gauges.

[0020] The beneficial effects of the present invention are to obtain the pressure head and lift of the turbine-type integrated machine pump end by measuring the inlet and outlet pressures and flow rate of the pump, and then calculate the pump end flow rate with a flowmeter. The speed and torque are measured by a speed torque sensor installed between the pump end and the turbine end, and a speed torque meter is provided to display the speed and input power. Finally, the pump end efficiency is calculated by the flow, lift, and input power. Similarly, the turbine end efficiency can be calculated, and the total conversion efficiency of the turbine-type integrated machine can be calculated by the efficiency ratio of the turbine end and the pump end. The creativity of the technical solution of this patent application lies in the structural design and overall layout of the turbine-type integrated machine test system, in which the test methods and calculation formulas of the instruments used are the existing technologies of hydraulic testing and hydraulic transmission, which are known to the technical personnel in the relevant technical field and are not described here.
