westfalia Purifier Problem

[osei7011]

In all I have 2 Hfo and 1 ME lo purifier,they all take water from the hydrophore line.the issue started with the ME LO purifier after it has gained the required rpm and I want to start the process,first it displays total de- sludging,then operating valve opened followed by the alarm 'FAIL TO SHOOT DE-SLUDGE MONITOR 'i have checked the water line n it has good pressure.
one thing I noticed is that before when I close the water supply and try starting the operation there is an alarm for BREAK OVER WATER but I tried that yesterday and there wasn't that alarm.
The number 1 Hfo purifier also started by giving alarm.for motor protection relay so I noticed the clutch disk were worn out which I changed and also cleaned the bowl ,changed all o-rings and boxed up.Aftwr starting the motor protection alarm has gone off only to be replaced with the same 'FAIL TO SHOOT DE-SLUDGE MONITOR ALARM' on the ME LO PURIFIER.
I seem to have checked any possible place I suspect yet to no avail...the ME LO PURIFIER has 3 solenoid valves whiles the Hfo has 6 ,2 for water and the rest still trying to find out.

How old is this stuff? I haven't seen this PLC 100 for years. I would run the machine manually (without the automatic program) to test the separation and the ejection but it is unlikely that they are all defective. It must be something common to all three. "The water has good pressure" what is the pressure? Is there enough volume (flow)? Send the full model numbers of the LO and HFO separators and more photos, please.

The vessel is 25 years so I presume same applies to the purifiers.The ME LO purifier is of the model OSA 20-02-066 whiles the HFO is OSB 35-0136-066.
The water pressure is about 3 to 10 bar,today I worked with the electrician all day trying to bypass sensors and also changing some yet to no avail.

The first picture is the arrangement of the water line,2nd is the valves on the purifier 3rd the Hfo purifier and lastly the lube oil purifier...

[popeye62]

Why is there such a large range of pressure in the water supply, 3-10b? Does the hydrophore need recharging on the gas side (check the pressure at the schrader valve with the water pressure relieved)? There are four valves on a 0136 Unitrol: operating water open/close and operating water displacement on the bottom of the machine and sensing line return to inlet and water/oil discharge on the top and also the conductivity sensor (there may be other valves downstream of these). The best way to bypass sensors is to run the whole thing in manual i.e. you are the sequence, just follow the sequence in the manual and open and close solenoids at the right time to see if the machine works. As I said before it is unlikely that all three are defective

Hi there, i have gea purifier too type osd 10, i have a problem that bowl cannot discharge and open , purifier bowl completed check and all o rings were replaced, water block strainer was cleaned too , manually overides the solenoid valves but still no any sound of discharging , any advice to solve the problem? Thx you

[popeye62]

Hello MVDSMC Can you give us more background i.e. what was happening previously? You won't hear the bowl open unless there is something in it so fill it with water and then try and discharge it. Are you sure the bowl is closing?

[Termica]

Good morning, I would like to see if any of you could help me. I have a GEA OSD 35 separator, this separator gives me an error code which is "water outlet flow too high" alarm. When it is put into service at the time that the sealing has to be done, it does not do so. And the displacement water gauge continues to mark. We have already changed the seals, cleaned the bowl, changed the module, changed the belt, replaced the clutch shoes. But it still does not do the sealing and gives the same alarm.

[MVDSMC]

It was overhauled and all the o-rings were changed after that it no longer discharges. It keeps working but doesn't discharge. The bowl is closing normally. I'm suspicious of the annular piston gasket polyamide. His height is 2.5mm out of the piece.

I don't know why the piston seal would be an issue. If it was leaking then the bowl would not close. I cannot see how the height would be an issue as it would just raise the piston higher in the water space that holds the bowl closed. If there is an issue with the piston then it could be the two lower piston gaskets, if they are passing the opening water might not be acting on the bottom of the piston to push it up and drain the closing water away, not something I have experienced. If you hold the opening water solenoid open for longer than the 2 to 3 seconds in the program will the bowl open? If not then there is either a leak of the opening water, not enough water or not enough pressure. Could the opening water be leaking past the piston and helping to keep the bowl closed? Was the piston freely moving when you opened it? Are all the spare parts original? Do you get any alarms? The speed of the machine and the pressure and volume of the opening water needs to be checked.

Hello Termica. Is it 0136 or 0196? Is it a D10 control panel? If it is Alarm #15 then it is a WMS fault. Have you tried what it says in the manual? Is there a lot of water in the FO or LO? T02 set too long? A leaking V2 valve? An 'incorrect setting on the evaluating relay' or T22 set too short? Have you tried switching off WMS?

[Termica]

Hello popeye. it is OSD 35-91-06. yes, it is, D10.

[Termica]

I'll send you the error codes for the separator. We have already reviewed the programs and sequence of selenoids, they are all correct. The problem that we have detected is that at the time it should seal, it does not do so and consequently the water pressure does not decrease, causing the separator to turn off. Now we will try changing the bowl from another separator to the separator with problems.

[popeye62]

OK, so it is not Unitrol and does not have WMS or SMS. It has a gravity disc and is open to atmosphere and is limited to 991kg/m3 density. It is purifying your LO. Am I correct so far? When you refer to 'the time it should seal' you are referring to the water seal not the bowl seal? Which water pressure is not decreasing: the displacement/sealing water (the water going in the top) or the operating water (the water going in the bottom)? Where are you reading the water pressure from, D10? In the last photo the sludge tank is in alarm, this will stop the machine. After you have stripped the sludge tank does the alarm clear? When does the alarm come? Is the sludge tank full of water or oil? Changing the complete bowl will eliminate a lot of possibilities. DO NOT mix up the bowl parts! (all rotating bits of the bowls must stay together)
