Hi, I am trying to solve a static structural problem in Ansys 17 but it gives me the error "An error occurred while starting the solver module. Please refer to troubleshooting section in Ansys mechanical user guide". I've checked all the possibilities in the mechanical user guide but nothing...
Hi everyone, we have a vertical pump (VS4 type) which has multiple bush bearings. During a previous overhaul, all bushes were renewed but when the pump was installed back, high vibration was recorded due to high bush clearances. Can anyone help me and provide me with a standard that mentions the...
Apologies for the 'in london' part. What I wanted to write was 'in the UK'. So if I look at the rankings Imperial is probably in the top 10 in the world while loughborough barely makes it in the top 100. But I really want to know which university is actual better in academic terms not just by...
Hi guys, I am looking to do my postgraduate at a good University in London and I am not a resident there therefore I am not sure about the reputation of the universities when it comes to Mechanical Engineering. I have done some research and I have shortlisted two Universities to do my MSc in...
Hi guys,
we are looking to buy a new horizontal overhung centrifugal pump and one of the suppliers have sent us the datasheet of a pump which puts the suction pressure at 0.30 barg, maximum suction pressure at 0.8 barg, and the vapor pressure of the liquid at 0.6 barg.
Now we know that if the...
Thanks guys,
The coupling is a jaw coupling.
The pump was initially overhauled due to the same reason, high vibrations. When our vibration analyst performed the analysis, he found high bush clearances to be the reason. We removed the pump and replaced the bushings with new ones as a lot of...
Hi, a VS4 type vertical pump is having high vibration though the pump was recently overhauled. The pump bushes were replaced during the overhaul and the sleeve-bush clearance was 0.28 mm. The issue was that the pump manufacturer did not provide any design range for the bush clearances therefore...
Hi guys, During the run-out check of a pump shaft, how important is it to make sure that the two V-blocks are vertically at the same level. In other words, the shaft being check for run-out is perfectly horizontal.
Thanks.
Thanks guys, the problem is still there. You guys suggest that there might be air trapped in the system. We do have a bleed valve in the hydraulic circuit which we have used to bleed the air out. Plus if air is trapped in the system, what usually happens is that the pressure in the hydraulic...
Hi, we have large actuators to control the operation of 20 inch butterfly valves. These valves are discharge valves of large vertical pumps. So recently we had to replace the oil (around 150 liters) of the control unit of the actuator. After replacement of the oil, the valve funcionality was...
Hi, quite recently I saw a plunger type positive displacement pump which had a strange plug at the bottom of the casing. The plig seemed to be slighlty leaking while running. When I removed the plug l, I found that it is not a plug but a sintered bronze air filter. This air filter was on the...
What about the front wing and the rear wing where the pressure on the top of the wing increases due to its profile as air passes over it at high speed. Shouldn't the increase in pressure cause the air temperature to increase which eventually should increase the temperature of the wing?
Hi everyone!! I was wondering during a formula one race, does the temperature of the formula one car skin (body and wings) increase due to its moving at high speed??
Thanks, but the rankings that you've showed seem to be for computer science major. Is there a similar list for "computational science and engineering"? or should a list for applied mathematics or mechanical engineering be relevant?
