RCF=g is the relative centrifugal force, which is a multiple of the earth's gravity, that is, the acceleration due to gravity.
If the motor r and g are known, the rpm can be calculated; conversely, if r and rpm are known, g can also be calculated.
For example, take a known r radius value on the r scale and a known relative centrifugal force value on the g scale, and the extension of the line between these two points at the intersection of the rpm scale is rpm.
If the known g value is on the right side of the g scale, then the value on the right side of the rpm scale should be read, and vice versa.
g and rpm can also be converted using the following formula:
RCF = 1.119 × 105 × rx (rpm)2
The relationship between the centrifugal force g and the speed rmin of the motor:
Centrifugal force (F);
Centripetal force is the attraction, repulsion or any tendency toward a central point.
Centrifugal force can be explained as the tendency of an object to maintain its "limited volume".
The difference between them is that the centripetal force is in an inertial reference frame, while the centrifugal force is in a non-inertial reference frame.
Formula: F=mω2r
ω: angular velocity of rotation (radians/second);
r: distance of the rotating body from the rotation axis (cm);
m: particle mass;
Relative centrifugal force (RCF);
RCF is the multiple of actual centrifugal force converted into gravitational acceleration;
g is the acceleration due to gravity (9.ms2)
Since one revolution is equal to 2π radians, the angular velocity of the rotor is expressed in revolutions per minute (rpm or n):
Centrifugation is expressed in r/min.
Separation factor calculation formula:
RCF=Fcentrifugal force/Fgravity=mω?2rmg=ω?2rg=（2＊π＊rr＊rpm）?2＊rg
Note: rpm should be converted to revolutions per second
For example: a motor with a diameter of 1000mm and a speed of 1000 rpm,
The separation factors are:
RCF(1000)=(2*3.1415*16.667)^2*0.59.8
=104.72^2＊0.59.8
=560
so......
G=?
When G=1500, theoretically any known metal can be cut.
The centrifugal force does not change.
Of course, the premise is that the drill bit is strong enough.
From to:
1500=r×11.18×10-6×(rpm)2;
The result is:
When the drill fixture diameter is 50MM
Rpm (rotational speed) =.
Liu Chi's hands moved at a high speed on the keyboard. It was a very big problem to turn the clock to minutes, especially on a motor with a diameter of only 200MM.
So Liu Chi decided to cancel the power generation device and use direct current directly.
Once again, make some magic changes.
......
Time flies.
"Ring, ring, ring..." The ringing of the phone interrupted Liu Chi who was doing an experiment.
"Hello?"
"Liu Chi, the thing you asked us to help you with last time has already had a result." Chen Luguang's voice seeking credit came into Liu Chi's ears through the mobile phone.
"?" Liu Chi couldn't figure out what happened last time.
"What?"
"What happened last time?"
"It's about your apprentice Zhou Meng. How come you forgot about it in such a short time?" Chen Luguang asked back.
"I was doing an experiment and I forgot about it for a moment. How is it going? Is there any hope?" Liu Chi came back to his senses and asked with a tense heart.
"There is a plan at the Air Force X General Hospital. After discussion and deduction, the success rate has reached 75%."
"Really? That's great. Should I prepare anything?" Liu Chi asked happily.
"We need Zhou Meng to personally check it out and confirm if there are any discrepancies with the medical records. If the discrepancy is too big, we will have to have another consultation."
"When are we going?" Liu Chi asked anxiously.
"On your schedule."
"The sooner the better."
"You can come over when you are ready. I'll give you a phone number and you can go directly to her." Chen Lvguang said, "I have already explained everything to her."
"good."
"XXX, Zhang Miao, is the vice president of the Air Force X General Hospital."
"Okay, I'll contact her later."
"Okay, feel free to contact me if you have any questions."
"good!"
"......" After Liu Chi hung up the phone, he thought for a while, and finally stopped what he was doing and called Zhou Meng: "Girl, where are you?"
"I'm in my sister-in-law's office." Zhou Meng's clear voice came from the phone.
"Please make time tomorrow and come with me to the KongX General Hospital." Liu Chi said directly.
"What are you going to do at the Air Force X General Hospital?" Zhou Meng asked puzzledly.
"Don't you want to become a beautiful young lady?" Liu Chi said half-jokingly.
"......" After a long while, Zhou Meng's trembling voice came out again: "Is it okay?"
"According to your previous case list, the success rate is 75%." Liu Chi comforted him, "Don't worry, it should be fine. If it doesn't work, Brother Chi will use money. We are not short of money."
"Well, thank you Brother Chi." Zhou Meng nodded heavily.
"Okay, that's it. Take advantage of today's time to deal with the things you need to do in the next few days. Although you have to go for an inspection tomorrow, the time later may not be short."
"I've been out for some time recently and may not be back in the short term."
"Brother, where are you going?"
"I'm going to do technical research on the project above. I'll leave after Brother Chi finishes the things on hand. It's more urgent over there."
