The spray pump is the purpose of the transformation of energy by fluid flow to achieve the purpose of transportation. Use it to transport liquids or gas. In chemical production, steam is often used as a working fluid for the spray pump, and it is used to draw vacuums to cause negative pressure in the equipment. Therefore, it is often called the steam jet pump.

Working principle: Water steam is sprayed out of the nozzle at a high flow rate under high pressure, bringing low -pressure gases or steam into high -speed fluids. The inhaled gas is mixed with water steam. As a result, it was rising and finally discharged through the outlet.

When the spray pump is mixed with the size of the hybrid fluid and the shorter of the throat and the length of the throat. In the large hour of regulating the flow of hybrid fluid, the flow of the power solution also changes accordingly, and the speed of the power solution also changes when the speed is through the nozzle. As a result, the phenomenon of air erosion changes from strong to weakening with the decrease in the flow of mixed solution until it is completely eliminated. From the three different throat distance work experience, increasing the throat distance can increase the circular area between the nozzle and the throat, and the flow rate of equal fluids will be lower at the time of the large area. To higher, the phenomenon of air erosion is even more difficult to produce.

At a certain temperature, the liquid is reduced to the pressure of the liquid at a certain temperature, and the liquid is generated by the liquid. This phenomenon of bubbles is called steam erosion. The air bubbles produced during the steam erosion are reduced to the high pressure place, and the volume is reduced to cause the crushing. This phenomenon that the bubble disappears in the liquid due to the rise in pressure is called steam erosion.

During the operation of the pump, if the local area of the overcurrent part (usually somewhere on the import of the impeller's leaves) is somewhere due to some reason, the absolute pressure of the pumping liquid is reduced to the fluid vaporization pressure at the time, and the liquid is at this time. Starting vaporization, a large amount of steam is generated to form air bubbles. When the liquid containing a large amount of air bubbles is forward through the high -pressure zone in the impeller, the high -pressure liquid around the bubbles causes the bubbles to narrow sharply or cracks. While the bubbles are condensed and ruptured, the liquid quality point fills the acupoint at a very high speed. At this moment, it produces a strong water shock effect, and it produces bubbles and bubbles in the pump. Steaming process. After the water pump produces steam erosion, in addition to the destruction of overcurrent components, noise and vibration will produce noise, and the performance of the pump will decrease. In severe cases, the liquid in the pump will be interrupted.
