Problems solved by technology

[0006] At present, in the construction of the test bench, the function is relatively single, and the test bench needs to be changed in the multi-purpose test task of the liquid-air jet pump, which will bring some unnecessary workload and waste. In addition, there is no convenient and reliable method in the prior art. In order to solve problems such as dosing methods, the present inventi

Embodiment 1

[0023] like figure 1 As shown in Fig. 1, a multifunctional test bench for the performance and application of liquid-air jet pump is composed of a test system and a dosing system.

[0024] The test system includes the main water tank 4, the centrifugal pump unit, the liquid-air jet pump 10, the test parameter measuring instrument, the connecting pipeline and the gate valve; and the cross-sectional area of ​​the main water tank is 1.8m 2 , the centrifugal pump unit includes a motor 1 and a centrifugal pump 2; the suction end of the centrifugal pump 2 is connected to the main water tank 4, the outlet pipe of the centrifugal pump is arranged vertically upwards, connected to a liquid flow meter 16 installed horizontally, and the pipeline that turns vertically downward is provided with a second Three presses 15 are connected to the liquid-air jet pump 10 to be tested; the outlet pipeline of the liquid-air jet pump 10 is connected to the main water tank 4 after connecting the first ...

Embodiment 2

[0029] Same as Example 1, the difference is that the test is the waste gas absorption simulation test process: based on the performance test of the liquid-air jet pump, the gas sucked by the liquid-air jet pump 10 is industrial waste gas or artificially set simulated waste gas, which is measured by the gas concentration meter 12 For gas inhalation concentration, the gas concentration meter 19 measures the gas-liquid concentration after gas-liquid mixing and separation, and after the gas is discharged. Similarly, the gas flow meters 11 and 18 measure the inhaled gas flow and the exhaust gas flow respectively. The liquid phase concentration is obtained by measuring the liquid phase concentration sensor 25, and the liquid phase concentration meter 26 reflects the concentration, and monitors whether the water body is close to saturation, thereby judging whether it is necessary to open the shunt gate valve 21 for drug administration. Part of the water pressurized by the centrifugal ...

Embodiment 3

[0031] With embodiment 1, the difference is that the test is an oxygenation and aeration test process: based on the performance test process of the liquid-air jet pump, the water level in the main water tank 4 is calculated by the water level of the liquid level gauge 5 before the test. The dissolved oxygen in the water body in the main water tank 4 drops to nearly zero, and the centrifugal pump 2 is turned on to provide working water for the liquid-air jet pump 10. The liquid-air jet pump 10 sucks air, and the air mixes into the main water tank 4 for oxygenation. The data of the liquid phase concentration meter 26 is recorded at intervals, reflecting the change of the oxygen concentration in the main water tank 4 until the oxygen in the water reaches saturation, and the oxygenation and aeration test process is completed. Wherein the threading sealing cover 27 not only allows the concentration meter cable to pass through, but also the thermometer and other signal cables can pas...

Abstract

The invention discloses a multifunctional testing table for property and application of a liquid and gas jet pump and belongs to the technical field of ejecting. The multifunctional testing table is composed of a testing system and a medicine feeding system. The testing system comprises a main water tank, a centrifugal pump unit, the liquid and gas jet pump, a testing parameter measuring instrument, a connection pipeline and a gate valve. The medicine feeding system is formed by a main water tank, a centrifugal pump unit, a medicine feeding box, a liquid and liquid jet pump, a pipeline and a gate valve. The multifunctional testing table can perform liquid and gas jet pump performance testing and can perform simulation study on structural size optimization and actual application of the liquid and gas jet pump by utilizing waste gas absorbing simulation experiments and oxygenating aeration experiments of the liquid and gas jet pump.

Description

technical field [0001] The invention belongs to the technical field of spraying, in particular to a multifunctional test bench for the performance and application of a liquid-gas jet pump. Background technique [0002] Liquid-gas jet pump is widely used in injection technology as an auxiliary equipment. It uses a pressurized liquid-phase fluid to be sprayed through the nozzle, and the gas-phase fluid around the jet is driven by the entrainment of the jet to flow together, thereby sucking the gas. After the gas-liquid two phases are mixed, the energy and mass transfer between the two phases occurs. Due to the advantages of simple structure, no rotating parts, suitable for various fluid media, etc., it is widely used in electric power, chemical industry, environmental protection and other fields. [0003] In the performance research, design and optimal size research of liquid-air jet pumps, empirical formulas are mostly used, because the jet mixed flow in a limited space is m...
