Anyone has experience about v-jet pigging? When using double pig with V-jet followed, how would we deal with the pig moves down through riser, 1st pig can drop down and void can appear between two pig?
Many thanks
@RobyengIT: I did not ask for a single valve bro. I asked for its function in system.
BTW, I contacted them weeks ago but I have not received any responses.
Is anyone familiar with hydraulic schematic in Italgru crane?
I wanna ask about function of valve 015 (red rectangular) in block 574 (attached file)
Many...
@BEMPE16524: I thought I was 2 way cartridge valve as you mentioned but is it possible to flow from B to A if B generates force more than spring's force?
@BEMPE16524: Thanks for your suggestion. That's what I'm doing but not every line has a port for monitoring Pressure.
Besides, anyone know what's the name of these valves in red rectangular (attached file) and how it works...
@LittleInch: Thanks for your help. I contacted with operator but sadly they don't have description.
@MintJulep: I search ISO symbols and see almost valves I need there. Manay thanks.
@3DDave: The way you mention is what I'm going to test: insert pressure gauges to all port in the block to see...
Hi everyone, I'm newbie in Mechanic.
Anyone know about reading hydraulic schematic of crane (Italgru C1515)?
I'm concerned about the workflow of hydraulic from starting/working/standby and shutdown especially of Winch.
I attached P&ID of hydraulic shcematic.
Thanks in advanced...
Sr for lately reply, We suspected that suction strainer was blocked so we opened for inspection.
Finally, we found that scale precipitated in strainer very hard
@gorgeverghese
We cannot take a sample from surge drum under vacuum condition unless we close the vent line and build up pressure in surge drum (0,02 -> 0,2)
According to design, fuel gas purges into bottom of reboiler (connected with surge drum) and these drums vent to atmosphere so it’s hard to vacuum inside.
_ I think NPSH maybe due to scale precipitate in suction flowline.
My field is using plunger pump to circulate LEAN glycol from glycol surge drum to glycol contactor. Does anyone know why vacuum happens in the suction of plunger pump? And how to take a sample of glycol if it is vacuumed? (Sample point locates in a pipeline from glycol surge drum to plunger pump...
