Imported steam jet injector

Imported steam jet injectorReusing waste steam can improve steam generation efficiency and reduce energy costs. The structure is simple, compact, small and lightweight, easy to install into pipelines, and can also be installed overhead. The cost and operating expenses are relatively low. There are no movable or rotating parts that require almost no maintenance, which means the equipment can be installed in remote locations. Oil free discharge ensures no lubrication pollution and is suitable for operating in hazardous areas with almost no noise.

working principle

A steam injector can be described as a special type of injector that uses high-pressure steam (known as power pressure) to inject low-pressure steam(Known as injection pressure)After the two types of steam are fully mixed, steam with a specific pressure between high-pressure steam and low-pressure steam is obtained at the outlet.

one step:Static pressure, second step:High pressure conversion to high speed, third step:Open pipeline, fourth step:Closed pipeline - side opening

High pressure steam enters the steam injector and converts the high-pressure energy of the steam into kinetic energy through the nozzle. When high-pressure steam leaves the nozzle, it enters the suction chamber at a high speed, where it interacts with the low-pressure steam injected into it

Steam mixing. There is momentum exchange between high-pressure steam and low-pressure steam, which accelerates low-pressure steam. A homogeneous mixture of gases passes through the narrowest space (throat) and ultimately recovers kinetic energy to pressure in the diffuser

Potential energy.

A steam injector is an injector that uses high-pressure steam to inject low-pressure steam and obtain intermediate pressure steam. The pressure of medium pressure steam is between high pressure steam and low pressure steam.

advantage (Compared with mechanical and electrical equipment)

simple structure Steam injectors can be processed from any material to improve their wear resistance.

Compact design and relatively light weight enable high-altitude installation.

The initial investment and operating costs are relatively low.

No moving or rotating parts, low maintenance costs, can be installed in distant or inaccessible areas.

No professional repair experience is required.

Steam is free from contamination by oil or lubricants.

Suitable for hazardous areas and does not require explosion-proof motors.

When recirculating through a pressure reducing valve, there is no loss of heat or energy.
