Comparing dynamic bahavior of Char-Lynn Q-Amp® orbital steering valve to Danfoss OSPC
zhlédnutí 286Před 3 měsíci
In this video I am comparing the dynamic behavior of Char-Lynn 262-3013-002 orbital steering valve to Danfoss OSPC 150-0179, both are 120 cc, closed-center, non-reaction steering units, but the Eaton steering has the Q-Amp® flow amplification.

Strange Behavior of Danfoss 155G4074 PVEH Electro-Hydraulic Actuator
zhlédnutí 253Před 3 měsíci
This is a single-section Danfoss PVG120 with a 155G4074 PVEH electro-hydraulic actuator (proportional high with active fault monitoring) mounted on a test bench in which the main motor is driven by a generic Variable Frequency Drive. The PVEH was entering the fault mode on power-up, and, by the looks of it, it was caused by the EMI from the VFD. This is the first time I have seen this happen - ...
Swash-plate neutral position visualization with a laser pointer.
zhlédnutí 214Před 7 měsíci
Rexroth A4VSG500EO2 - a 500cc closed-loop variable displacement pump with an electronic displacement control that uses an inductive swashplate position transducer and a directly driven proportional directional valve in conjunction with a VT 5035-1X controller card - I tied a laser pointer to the swashplate angle indicator to visualize how the EO2 control makes constant tiny adjustments to the s...
How Different Pressure Gauges Read Noisy (Subjected to High-Frequency Spikes) Pressure
zhlédnutí 200Před 8 měsíci
An example of how a respectable, time-proven, and ubiquitous Parker ServiceJunior digital pressure gauge can give an unstable pressure reading when a pressure source is "noisy" - i.e. "spiced" with high-frequency pressure spikes, and how a simple mechanical (bourdon tube type, liquid-filled) pressure gauge or a digital pressure measuring system that uses digital filtering (averaging) can succes...

zhlédnutí 627Před rokem
I was rearranging the shop the other day, and I found this very old "project" of mine I honestly thought was lost for good. It's some 20 years old. It's from the days when I was starting to work with hydraulics, and like any person who is initiating in an area that is new to him, I was inventing all sorts of crazy stuff back then (in hopes of revolutionizing the field, of course!) - and this cr...
How to Remove the Pulsations Orifice of the Rexroth A10VO(18...100) Hydraulic Pump DFR Controller
zhlédnutí 3,5KPřed rokem
The DFR/DFR1 controller of the ubiquitous Rexroth A10VO (sizes 18...100) hydraulic pump has the so-called "pulsations orifice" (or better - a "double orifice plug") in it, which may be tricky to remove (for cleaning and replacing the O-ring seal). Just wanted to show another way to pull it out.

Showcasing an idea for a DIY extractor for pulling bushings out of blind bores. (The DIY term is pretty relative here because you do need a lathe to make this tool). More details at www.insanehydraulics.com/hydraulictips/diybushingextractor.html
Evaluating Leakage of a Rexroth A10VO100 Bias Servo-Cylinder
zhlédnutí 712Před rokem
I wanted to find out how much the bias servo-cylinder, which is always connected to the pump outlet, adds to the case drain flow in a Rexroth A10VO100 hydraulic pump. I was also wondering if the noticeable wear mark on the sealing surface of the piston shoe would add much to the leakage. Surprisingly, the leakage is extremely small. Even for the heavily marked shoe. More details here: www.insan...
Testing NG06 interface leakage using a reciprocating valve
zhlédnutí 585Před 2 lety
I used a reciprocating valve to see if I could simulate an NG06 interface leakage after it was mounted with wet seals (as described in the SUN Hydraulics article on Mounting and Assembly of Sandwich Bodies). Details on this "endeavor" will be posted later today on the Insane Hydraulics blog.
Setting Tapered Roller Bearings on Rexroth A10VO100 Hydraulic Pump

This is just a quick illustration to show how changing the tapered roller bearing preload affects the "binding" of the shaft - something you can use to set such bearings without special tools (when you have enough experience)
I built a tabletop device that can reach the pressure of the bottom of the Mariana trench!!!
zhlédnutí 665Před 2 lety
I needed a small tabletop device to test pressure sensors and pressure gauges in my lab, and since I had a lot of industrial scrap accumulated in the shop, I thought I might as well build one myself. It works surprisingly well, and it looks and feels (and sounds) pretty cool, too!
Silicon Labs BGM13P22 ADC and LCD Test

This is my newest "toy" - the BRD4001A Wireless Starter Kit from Silicon Labs with a BRD4306A Blue Gecko Board (containing the BGM13P22F522GA Module). I put together a small piece of code just to test the module's ADC as well as the board's Sharp Memory LCD. I am moving the Wireless Monitor Project (www.insanehydraulics.com/wireless.html) to this platform.

Hey mate, How did you go with these? It looks like a very neat project! Cheers, Rog
Been following the web page InsaneHydraulics a few years and today I Googled the how to install Piston ring on a A8VO and here I am . Thanks a lot for all your effort.
Your video's sir are always Excellent.
What type of potentiometer you are using please?
Looks like a ten or so turn pot with a fancy housing
Hi, I like your videos. It’s hard to find people with great hyd knowledge. You have a new subscriber
Thanks!
Now we have "hydraulic clamp amp meter"😂it measures hydraulic voltage ⚡
Great job 👍
Danfoss OSPC orbitrol main relief valve setting 190 bar and shock valves setting 240 bar so if you test with pressure more than 190 bar then it's normal to become reaction orbitrol if you not then there's a wear in main relief between valve poppet and its seat "make it act like an orifice!!".on other hand in real application there's always pressure supply from steering pump so even if there's a wear Volume flow rate of oil will make delta P across that orifice"failed relief"! that will not allow steering wheel to rotate back like that.
Excellent
Just subscribed to your channel, great tip.
last week i did A4VG250 block and plate match lapping by hand, next time going to employ Your invention. Thanks for sharing Your brilliant idea
Cool! Best of luck!
Thanks for sharing. I like your super automated and digital counter. 😁
Is that a socket you're using?
Great video, thank you! Is the wireless gauge on the market yet?
Thanks! Not yet, but it's getting there :)

with the Hydraulic flow completely off, My new Holland tractor steering box makes a clicking noise while turning the steering wheel left or right. At the moment the steering is NOT working on my tractor. Just trying to troubleshoot my problem. I had a low level of hydraulic fluid and was working the tractor on a steep grade. could the low fluid level or hard jarring of hitting large rocks with the tires broke something inside the steering box? won't even turn the wheels with the wheels off of the ground.
Nice, now we need something to measure how much the hose shortens as pressure rizes
Hello I have this problem What doi do to fix it?
good ....
Maybe anti-cavitation check valve not working properly because you put orbitrol in horizontal position
When you say one port is connected to tank and the other is pressurized, do you mean the hose connected to tank is filled with oil or there is still air filling the hose
The hose connected to tank is filled with oil.
I'm not an expert in hydraulics by any means, I will go out on a limb there and say massive internal leakage of the pump. Love your channel, love your blog. Thanks for what you do, greetings from Italy.

great job
Awesome music!
I used a large wall-anchor (Rawl-bolt)
That is awesome! Thanks for filming it!
that is surprising how low the leakage at that pressure
Thank you for the video!!!

Bem feito e uma excelente ferramenta, parabéns
Obirgado, Fernando!
Já tinha visto uma coisa parecida na oficina de manutenção da Celtejo
Nice work, did you build it for testing pressure switches or digital indicators?
Thanks! I use it to test pressure switches, pressure sensors, cells and transducers, pressure gauges as well ( I like building my own...). Whenever I need a static pressure source and a component is zero leakage.
Test to failure?
Love it, need it. Can it read upto 500Bar? Where do I order the parts? And where can I get the app from?
Hi, Daniel, this was a hobby project of mine that helped a lot with my work, but there just wasn't enough interest to justify the development of a sellable product. I built the app as well. You can catch the details and news (if there's any) here - www.insanehydraulics.com/wireless.html. I use it with 400 and 600 bar Gems pressure transmitters and Parker analog flow rate sensors.
was the music necessary !
I don't understand that
How about what speed is the bit (or lathe) turning?
Welcome to test HANJIU motor
cool
Super wow!
Wouldn't a squash plate be easier.
Wouldn't a universal joint be simpler and less expensive ??
This is like porn for a JCB digger !
Where is the animation? Downvoted.
what apps do you use to make this 3D object ?
This old project was done in Inventor, 2008 if I recall correctly...
