The pneumatic robot arm tool is to be mounted on the host machine.
After the new pneumatic robot arm tool arrived I found the host machine does not have enough vacuum ports to support all the tool functions. Instead the host machine comes with more than enough positive air pressure ports. So I came up with an idea to use a Venturi vacuum generator to convert positive air pressure fuction to vacuum pressure. Every technician knows how to connect a Venturi vacuum generator. Then I said something extra: Venruri effect is when you blow the air through constricted section (or choke) of a pipe, called Venturi pipe, the air flow speed increased, but the air pressure reduced, i.e. vacuum is generated around the Venturi pipe.
After saying that I successfully confused everyone.
The Venturi effect is simply Bernoulli's principle applied to a fluid that flows through a tube with a constriction in it. Bernoulli's principle (that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure) explains why airplanes can fly. :)

吸尘器的真空是电机产生的？ 相当于离心真空泵。 文丘里真空管是我们中学物理学过的。
恒定流量的流体流过孔径变小的通道时，流速会增加即动能增加，能量守恒，同时势能减少，压力减少。
文丘里管，是一个真管子，中间部分截面大幅度减小，这样气流流过时，速度突然大大增加，动能大大增加了，如果在变细的部分侧面有个开孔，开孔处就会产生真空负压，外面的空气就会被吸进去。这是文丘里负压。
利用文丘里现象产生的一般较低真空负压可以不用抽气泵，
They said not good at science... ... They call this---science
technique is about how to do it, science is about why,
