Hi, I am trying to size a correct motor for my pump. The setup will be, a motor connected to a reduction gear box and the gear box will be connected to a positive displacement pump. The process undertaken is as follows: 1) Look at the different pump ranges ( Flow and Pressures). From the...

I have an application as follows: I have positive displacement pump 1 that is pumping at around 6 BPM ( through a 4" pipe) at pressure P1. There is another smaller positive displacement pump 2 that is pumping at around 0.8 BPM ( through a 1" pipe) at pressure P2. These 2 fluids mix at a point...

Hello, This is with regards to Centrifugal pump operations and maintenance. We have a few Centrifugal pumps in our plant that pumps chemicals, heavy density fluids, viscous fluids etc.. How do we constantly ensure that the pump is in good condition? Is there any kind of predictive...

Hi, Is there an ASME standard for vibrations? e.g the maximum displacements and velocity for machineries? If so, it would be very helpful, if someone could direct me to that. Thanks.

Hi, I am having some drive shaft issues. I have posted this before. I did further testing and came up with some new results and thought i will share this with the community and at the same time I hope to get some direction in this forum. I have a PTO driving a Centrifugal pump. There are...

I am having a problem on shaft vibration. I have 3 shafts (york slip) that is running between a PTO and a pump.The three shafts are connected by universal joints. The three shafts goes through 2 sets of flange bearings, which are bolted to a steel wall. On one of the walls, there is excessive...

Hi, I am currently working on a project that involves specing out a bolt that would be used to hold an impeller to the shaft. I was wondering what are the forces that i should consider to spec out a suitable bolt. Thank you.

Hi, I am pretty new to Pro-E. I was wondering how you could add weld model to bond two surfaces for analysis. I do know that if you just constraint two surfaces, Pro-Mechanica treats that as a single body and i think that does not give a very accurate result when you do a stress analyssis...
