The utility model relates to a preservation type water-jet vacuum pump, which comprises a Venturi tube, a sucking room and a jet. 本实用新型涉及一种防腐型水喷射真空泵,它包括文丘里管、吸入室和喷嘴。
Venturi tube is one of key equipments in process of purification and recovery of converter gas, which is used to drop temperature of converter gas with spraying jet fixed at throat of Venturi tube. 文氏管内部的流动与传热较为复杂,不仅涉及喷淋液滴与烟气在流动过程中的相互作用,而且涉及喷淋液滴遇到高温烟气发生相变进行的传热传质。
The vacuum micro-tool consists of a venturi jet pump, a linear pressure regulation valve, two switch valves and a glass pipette suited for micro-operation. 真空微夹由真空喷射泵、线性压力调节阀、电磁开关阀以及满足尺寸和形状要求玻璃吸管组成。
It is well known that the jet flow loses its pressure at the throat when the high spees mixture of gas and water passes the throat of venturi duster, because the pressure loss at the throat has direct ratio with the square speed of the jet flow. 文丘里除尘器的压力损失主要是高速气水混合射流通过喉管而造成的,通过喉管的压力损失与射流速度的平方成正比。
