Liquid podoskgts to internal 3 using channels 14 and 11.

The gas is supplied to the outer conn 4 with the help of channels 15, 12, 16, 17 n of spears (go

The connection of the upper and lower parts of the core - (the position is sealed with procadco 19,

Kapapans 9 and U are copied in the form of KoijyeoB, and the entrances with it .. Bk, 11 and 12 have a conical shape with dimensions corresponding to 5, 5 and “and sizes to Papans. The outer nozzle 4 may be absent, then the nozzle is bu-; Detalate as a pulsating-mechanical device An insert with screw channels can be placed in the inner sopio, which will ensure. an centrifugal outflow, or with the viral and central channels, which ensures the watering of the cone, that is; Zeitrobetzhyu - jet flow, In cops, the target clearance between the nozzles can also

A spraying gas sprinkler must be placed.

The ffsunka works as follows.

If the pressure is higher than the flow of gas, then the liquid through the channel 14. enters the chamber A liquid chamber | and the gas through the canap .16 "-to the gas chamber B, from where through the canal 12 across Canada 16, 17 and 18 goes to the emergency 4

(in the gap between the dream). At the same time, valve 9 almost completely closes the entrance to the inner nozzle 3. The increasing pressure of the liquid bends the membrane 5, the axis 8 with the valve, 1 moves upwards, closes the entrance B channel 12 and opens the entrance to the channel 11, Pressure in the liquid chamber 5 is returned to its original position and a new start is started, by selecting a spring of 13 with an appropriate gesture.

Bone can be used to obtain the required frequency and amplitude of puffy-ups, if the pressure of the gas is higher than the pressure of the liquid, the axis 8 is set to m, that on average of each membrane the entrance to the channel 12 is open in the internal nozzle 3. The spring 13 is then placed in a dry cell. In the nozzle, the nozzle works as in the first version.

In case of equal pressures, the 5 and 11 alternatives are both given.

Fluctuations in the flow rate of a liquid lead to an increase in its surface energy and a thinnest surface. The pulsations of steam. The meters of atomized gas increase this effect. Thus, without additional energy consumption, it is possible to increase the fineness of sprinkling or reduce the energy consumption of nph of the same Dispersity, which will contribute to an increase in efficiency and efficiency of 3 whole heat and mass transfer processes.

Formula purchased

The pneumatic iJopcyHKa, which contains a composite housing with a gravitational nozzle for a scattering liquid and encompasses the outer bladder PM dp of the atomizing gas and with canaks for supplying these fluids, is equipped with a pulsator, which is equipped with a heart rate controller. In the form of a reinforced s hull of a flexible membrane with a valve fixed on it with a valve, located on both sides of the membrane in the fluid chamber of the hull opposite the supply channels of these media to the corresponding chambers. m nozzles,.
