Hello Guys, We have a problem with the machine. The pump mentioned in the scheme position 112 doesn't give pressure to the other manifolds. We tried to close the pump delivery and the pressure was around 180 bar, which means the pump is ok and probably there is some leakage in one of the...

Thanks, Brain Peteren for your explanation but please see the figure below. When the press is extruding.It is using the force of the main cylinder and the two side cylinder and since the pressure is force/ area why the pressure on TR 20.1 and TR 20.2 is the same. Shouldn't the side cylinder...

Hello all, I am curious to find out. Pressure on a hydraulic cylinder is force/ area. But why in extrusion press where there are two side cylinders and one main cylinder attached together have the same pressure when they are extruded.Shouldnt the side cylinder have more pressure than main...

Thanks Akkaman, But could you identfiy the parts in this diagram. https://photos.app.goo.gl/QMMriA579GzZbuMg9

Thanks Ted, But is it possible to tell from the schema which direction the spool moves in case I apply -10V without looking up the manual

Hello All, Just a quick question. I am learning about hydraulics these days. I have some doubts about the prefill valves. I understand how they work. I understand the hydraulic schema but can someone mark to me about the actual parts vs the symbol parts. Where is the magnet on the position...

Hello, I am automation engineer so please excuse me. I was wondering ,Is it possible to know in which direction the spool moves for applying position voltage and negative voltage without reading the manual and only accessing the diagram on the valve. I am talking about the proportional...

Thanks Hydtools, So when EV 16 is off. There will 0 bar pressure at MX3 and 300 bar at MX4 (considering the relief valve from the pump is set 300 bar). Is that right.

Thank you but I one question, . If EV1-16 is cut we read 0bar in X3 and 160bar in X4. Regarding the above why dont we read 300 bar at X3 since that in input pressure from the pump. Dont you think X3 should read the 300 bar. Correct me if I am wrong

Sorry guys an automation guy so be patient with me. If I set from the pump at point B with 320 bar flow set on relief bar and 160 bar set for point A on the pressure reducing valve . What will the pressure read at port MX3 and MX4. If Ev 1-16 is off while pressure read o bar at at Mx3 and 320...

Sorry but for my understanding. THe more the pressure difference the higher will be flow rate and the speed of the cylinder is only related to flow rate and area of the pistion during extraction. So why the pressure drop does decrease the flow rate of the fluid

Thank you guys. I changed to hydraulic resistance of the valve in the software and it work as it should. Thank for your support

Hello all, I am trying to play with the hydraulic fluid simulator. I was trying the regenerative circuit to see the increase in cylinder speed during extraction. When I connect the rod end as attach in image1 I get slow speed but I connect as in image2 the cylinder advances real fast. What is...

Sorry. Is the new image. OK. https://files.engineering.com/getfile.aspx?folder=14d9d2dc-6cde-4c0e-ae57-b826e73904ed&file=Pump__question.jpg

Hello all, I am sorry I am a automation guy. Please answer me this question. THe attached image. If I am pump feeding from P1 what will the pressue tranducer at P1 read. Assume all the valve are not acutated. Will it read 0? ...

Hello all, I have the cylinder as attached. I need to have the pressure of 300 -310 bar at transducer 3.1. I have set VP3-5 to -10V . Vp 3-1 to 10V and vp 3-4 to 0v. My cylinder is building pressure of 300 bar but it is very slow. What could be the...

If I apply pressure to Port B of the cartridge valve, Can flow occur from B to A. What condition will cause flow from B to A ? Or is it always A to B for this circuit

Thanks for the explanation guys. Fantastic. This forum has some many knowledgable persons @hydtools . I am referring to the one with the that looks like a pencil point

Hi, Thanks for your reply. I am not a hydraulic guy but please excuse me If I am stupid "With the DCV de-energised, the top chamber on the cartridge is vented to tank through the open centre of the DCV (with supply pressure dropped across the 0.8 mm orifice that'sin line with the bottom X port...

What about the flow at the cartridge valve. Does it open to allow to open.
