The water ejector system consists of the following parts: water ejector, water ejector, operation water source, vacuum pipeline from water ejector to gas ejector, and water ejector emission system.
The function, operation, structure and hydraulic condition of water ejector
function
The ejector has two important functions: producing the vacuum needed for the job and producing a solution.
1. working vacuum
When no gas is added, the ejector design creates a vacuum. Rely on a vacuum to breathe gas or liquid. Note that the vacuum generally does not absorb powder or similar solids.
2. Solution production
The design of a water ejector enables the flow of water in the gas and water ejector to produce a concentrated solution and is added to the dosing system
Point.
operation
In a water injector, the pressure water generates a vacuum through a venturi nozzle and throat
The pressure of the water ejector is the speed of the vacuum, and the velocity required by the flow is at the entrance of the ejector
(inlet pressure) produced by the pressure difference between the exit of the injector (back pressure). If this pressure difference can not be
Maintenance does not produce enough vacuum, and the ejector will take advantage of all the available pressure upstream, unless at a particularly high level
Under pressure.
structure
A water ejector has the following general parts:
A. pressure water inlet / outlet
B. nozzle / throat assembly
C. gas inlet
D. check valve combination
The nozzle / throat combination is different depending on the amount of gas required and is provided with the hydraulic conditions provided
