Here are some key references and manuals that can guide your screw feeder and hopper design: CEMA’s "Screw Conveyor Engineering Guide" (CEMA 350): This guide provides detailed information on screw conveyor design, power and torque calculation, and the forces exerted on the screw and surrounding...

start with what you really want to achieve. list out all pro and cons include all factors such as: cost, machinability, raw material, maintenance, etc... R.Efendy

there are few free to use online software out there you can compare the results from them as well. R.Efendy

yeah, drain line is common. the manufacturer should already connected all the lines. here what may be the cause: 1. When the motors run under light or no load, the hydraulic fluid may not be under enough pressure to fully fill the motors’ chambers, leading to cavitation. Cavitation happens when...

304 is not advisable as per what you have experience. it will fail. R.Efendy

having said all the possibilities that you have mentioned, have you tried change to SS316 circlip? R.Efendy

perhaps... R.Efendy

OP, you copied exactly your lecturer's question and paste it here? R.Efendy

we design a subsea light many years ago. we used clear borosilicate to make the glass dome. Carlton Glass can customise the shape you want. the glass is very sensitive to stress concentration, so we have to carefully design the holding mechanism for it. also, we will not allow long duration...

if you use proportional valve, you can control the start of the motor once you touch the load. What you experiencing is normal especially when you put the motor in series and the disc that you fix on the motor. just try to remove the possible trapped air in the line and see how it works. also...

not sure this may help or not, but you can try. here is what I found from the net: "DIN EN ISO 11970 (for welding procedure specifications for steel castings) or DIN 17205 (which is an older German standard for steel castings) may include more detailed guidelines or references to cast-on test...

you are talking more towards piping system internal hydro pressure test. need to install relief valve somewhere at higher point of your system as there maybe air trap inside the line. make sure your flushing point is at the very lowest point. and yes, you need to flush the line before real test...

AWWA M55 focuses mainly on design aspects of PE pipes under internal pressure and soil loads, and does not cover this specific scenario of deformation due to subsea conditions and external constraints. could provide guidance on estimating the forces: DNVGL-RP-F109: Covers on-bottom stability...

why not use something available in the market? we have hydraulic press with gauge. you can try search for enerpack or enerpak. R.Efendy

You mention the main shaft will be driven by a motor but I don't understand where the other motor goes. R.Efendy

[king] OP, srv can mean anything. R.Efendy

Are you considering anything to be attached to the shaft? Such as gearbox, bearing, etc.? What is the purpose of your winch? It's quite odd to have a solid shaft for that quite big winch. R.Efendy

maybe can help you: 1. Link 2. Mikhail Slobodyan Link did a study on this. but you need to find a way to access the paper. R.Efendy

ΔC= (L/2⋅π)−R ΔC is the required reduction in center distance. L is the belt length. R is the radius of the larger pulley (driven or driver). Alternatively, a practical rule of thumb is to reduce the center distance by 1-3% of the total belt length, but this can vary depending on the belt...

basic foundation: note: this is just a basic example. R.Efendy
