Hi Guys,
I have a system as in following image:
it is a launch and recovery system (LARS). the snubber will carry a suspension load and move together with the LARS leg (luff in/out).
the operating pressure is around 210Bar.
So I'm trying to understand the hydraulic diagram here but I still...
Hi All,
Anyone familiar with the construction of wheel track:
what is the black material? is it a solid rubber that wrap the wheel?
any idea of any company producing the complete assembly in UK or Canada?

Hi all,
Anyone has experience to repair the bellow? any suitable glue, etc. for it?
my bellow as in attachment.
my operating pressure internally is very low, 15 psi max...
dear all,
I am dealing with an underwater vehicle.
actually this is my first time facing this issue after so many years of working with the same fiber optical multiplexer (see attachment page 3.8).
the card is 907 Plus multiplexer (with remote card at one end and console card at the other...
Hi All,
Hopefully I'm in the correct room.
I'm planning to use some available in the market CWDM for my own project as describe in photo:
there are links for the products below...
Hi, I'm looking for an alternative brand for this type of potentiometer.
using it for a joystick project. It should be able to work for +/- directions.
currently using Contelec (PL310 model) brand but curious if anyone have any idea on other brand which I can't find in google.
or is there any...
Dear All,
I have a confusion here. I have a working system like this,
Electrical motor:
RPM: 1500 @50Hz
Full load torque: 1651
Power: 250kW
Hyd pump:
Model: Eaton PVWS 360M (variable displacement)
flow: 360cc
Power consumption: 315kW @ 350Bar
Driving torque: 2005 @ 350Bar
above pump will...
Hi,
As title indicates, I wonder what did I do wrong?
After importing to specific folder of the profile, I can't get all new profiles.
Please someone help.
Thanks.

Hi All,
I have a system like this:
-variable displacement pump maximum 360cc.
-operating pressure 200-220 Bar
-Calculated system flow at 1800RPM at 220 Bar is 648 lpm.
-the pump is needed to run a hydraulic motor only.
-the pump and the hydraulic motor location may not be too far apart (around...
Dear All,
I have a system where the pump (Rexroth AA10VSO Series 31) output is controlled by means of a control valve pack.
I'm just wondering how can the output be controlled if the pump shaft speed is same as drive motor speed and the speed is constant throughout the process.
Sorry, I'm not a...

Hi All,
Please let me know of any manufacturer/supplier who sells just stator/rotor assembly only. Basically it will be an oil filled motor housing.
One of my common supplier is Ziehl Abegg. I need some other options please. 100HP and above.
TIA.

Hi All,
I want to know how can i model this situation in Solidworks simulation. This solution was done using ANSIS by someone.
Can someone guide me please.

Hello guys, i have tried to figure out why do they make the base unparallel as in the photo (you can see the hydraulic cylinders as well) but can't think off anything logical.
appreciate all ideas.

Hi All,
I have a Rexroth AA10VSO Series 31 hydraulic variable displacement, axial piston pump (please see attachment)
The reason I want to convert it to fixed displacement is because we don't need any variable output anymore. we will have a mechanical softstart for the hydraulic.
Also we need...
Hello Everyone,
I'm trying to figure out the acting force on the the wall/fence of a cable carousel as in following image:
I tried to look for a design standard but so far I couldn't find one. So, here is my assumption:
n : vertical number of cable layers
nh : number of cable turns on each...
Hi All,
I'm sure there is a correct formula to calculate the volume flow rate.
But i just want to know if my common sense is generally correct or wrong.
Volume flow per revolution of a propeller = 3.142 x (radius of propeller)^2 x L (as in photo) x no. blade?
Thanks in advance.

Hi Guys,
I have a problem with a PVG 120 valve.
The schematic is shown in attachment (marked as DCV-1).
When i operate other functions (using PVG32) besides 'Luff'(using PVG120), the luff cylinder is pushed out.
Regardless whether i operate the lever up or down, the luff cylinder will be...
Dear Experts,
I just want to know if my assumption is correct:
Line pull = 65,000 N
Safety factor = 3
Total, Ft = 195,000 N
Drum core Diameter, Dc = 1.2 meter
Drum Width, Wd = 1.5 m
No. of wire wrap = 37.5 (on single layer)
Circumference, C = pi.Dc...
Hi Guys,
I would like to know how to identify the axial load for the bearing as attached.
From the datasheet, the basic dynamic load rating is 186,000N.
Minimum axial load factor is 0.0512.
Is the axial load = 0.0512 x 186,000N...
