Description

Pressurizing method of self-pressurizing type injection pump

The technical field is as follows:

the invention relates to a pressurizing method of a self-pressurizing type injection pump.

Background art:

the traditional ejector pump device mainly utilizes the turbulent dispersion action of jet flow, and has no auxiliary mechanical device, so that the energy transmission efficiency is low; the operation energy comes from high-pressure gas, the regulating capacity in the operation process is poor, the flow rate of the suction flow is related to factors such as the size of a pipeline, the external pressure and the like, and the environment adaptability is poor.

A jet pump is a device that allows the momentum of a high energy fluid to exchange with energy and a low energy fluid by expansion of the high energy fluid as it passes through a nozzle. The nozzle expands to form a jet, the jet is exposed to low-energy fluid, a shear surface is formed between two high-energy and low-energy fluids, and the momentum and the kinetic energy of the high-speed fluid jet flow are gradually transferred to the low-energy fluid through the viscous shear surface and the mechanical action of viscous shear force and fluid diffusion.

The high-speed fluid is ejected from the ejection nozzle and enters the mixing section, the high-speed fluid forms suction due to viscous shearing force, the fluid at the inflow port is sucked to form suction flow, the suction flow and the high-speed fluid ejected from the ejection nozzle enter the mixing section together, and the mixed high-speed fluid flows out from the right side of the mixing section. The flow rate of the suction flow is therefore dependent on the discharge flow rate of the injection nozzle, the temperature, the inlet opening area and the ambient pressure.

The invention content is as follows:

the invention aims to provide a pressurizing method of a self-pressurizing type injection pump.

The above purpose is realized by the following technical scheme:

from pressurization formula ejector pump, its constitution includes: the jet pipe is connected with a front support of the rotor support, a front rectifying cone is mounted at the front end of the front support, the rear end of the front support is connected with a support, an inner support of the self-pressurization rotor is mounted on the support, turbine blades are mounted between the inner support and the outer support, a pipeline type axial flow fan blade is mounted on the outer side of the outer support, a rear support of the rotor support is mounted at the rear part of the support, the rear support is connected with the mixing pipe, and a rear rectifying cone is mounted on the outer side of the rear support.

The turbine blade, the inner mounting support, the pipeline type axial flow fan blade and the outer mounting support form a self-pressurizing rotor system, the self-pressurizing rotor system is mounted on the support, one end of the support is mounted in the injection pipe through the rotor support, and the other end of the support is mounted in the mixing pipe.

The pressurizing method of the self-pressurizing type injection pump comprises the following steps: firstly, high-pressure airflow flows in from the injection pipe, is rectified and compressed by the front rectifying cone, then impacts on turbine blades of the self-pressurizing rotor at a higher speed and a higher pressure to push the self-pressurizing rotor to rotate at a high speed, then the self-pressurizing rotor rotating at the high speed generates a strong suction force through the pipeline type axial flow fan blades on the outermost side, external fluid is sucked into the mixing pipe, external fluid is introduced, and finally the high-speed injection flow mixing with the turbine blades is completed.
