Why are multi-stage ejectors required?

Multi-stage injectors are needed for the following reasons:

Increased fluid pressure

The multistage jet pump consists of multiple centrifugal jets superimposed, each of which can accelerate and send the pumped liquid out, and the outlet flow rate of each stage of the jet is higher than that of the previous stage, so as to achieve high-pressure fluid transfer. This design can effectively increase the pressure of the fluid to meet the needs of specific application scenarios.

Adaptation to harsh conditions

In some specific applications, such as oilfield gas production processes, the injector is required to meet the harsh conditions of a small pressure difference between the mixed fluid and the working fluid, to achieve a large compression ratio, and not to allow a portion of the media to be diverted from the stage of the injector. Single-stage injectors are unable to meet these requirements, while multi-stage injectors are able to meet these conditions by step-by-step pressurization and acceleration of the fluid.

Energy saving and environmental protection

Multi-stage injectors can improve energy efficiency, reduce energy consumption, and thus reduce operating costs. At the same time, due to its ability to efficiently transport fluids, it also helps to reduce leakage and waste, and achieve the effect of energy saving and environmental protection.

Wide range of application scenarios

Multistage ejectors have a wide range of applications in many fields, such as high-pressure water cutting technology, oil extraction, high-pressure cleaning, etc. These applications require high-pressure fluid transfer, and multistage injectors are an effective tool to achieve this.
In summary, multistage ejectors are widely used because of their ability to increase fluid pressure, adapt to harsh conditions, save energy and protect the environment, and meet the needs of a wide range of application scenarios.
