Hello Baluncore, Can bushing be a safe option if my speed has gone down to 700 RPM from 1500? Thanks!

@https://www.physicsforums.com/members/jrmichler.632719/: Thank you very much for this, I can take look and get back. Hopefully I can get something which is food grade. @Dr.D: Agree with you, however, I work in an industry where safety is paramount. And unfortunately, my requirement necessitates...

Hello All, Very new to design , especially in material selection and rubber stuff. I have requirement where piston/shaft reciprocates to housing at high speeds. In order to reduce noise and for safety reasons, I must add rubber pads on both. Application as below: Red part is the...

Hello Baluncore, Thanks for taking time on this, below are some details; 1. OD of red shaft is around 8mm 2. ID of air flow tube around 20mm 3. Need to design a low pressure loss valve, I suspect the loss will be around 5 - 10 cmH2O 4. Side forces on red shaft would be the force due to air...

Hello All, I am new to designing, and I need to design an air tight tubing with a motor shaft running thru. Following are representative pics: https://www.physicsforums.com/attachments/215901 https://www.physicsforums.com/attachments/215902 Blue arrows indicate air flow direction. Red part...

Hello Asymptotic, Thanks again for that explanation. That link does a very good job of elucidating the difference between pressures keeping different applications in mind. Just as a future reference for others, the below link might help as well...

Hello Asymptotic, Thanks a lot for the detailed explanation. It is in fact a micronel blower I'm looking at and specifically this: http://www.micronelusa.com/uploads/tx_micronel/U65M2-024KX-5_without_integrated_electronics_01.pdf Your explanation of the 3 types were very helpful. Now I would...

Hello JRMichler and Russ_watters, Thanks a ton for the quick response. On the blower (that I am interested in ) data sheet I was unable to find any info about RPM for the given blower curve. However, on closer look at the table gives me the following: Nfree blowing Ntyp. working point Nstatic...

Hello All, I need some basic understanding between theory and practical with respect to blowers. Blowers usually come with blower curves which give a relationship between Static Pressure and Flow. Usually, SP is inversely proportional to Flow, as in SP increases as flow decreases. Example of a...
