Thank you Ronald!

There is lot of videos on. Channel check playlists also

Thank you dear friend!

Thanks!

Thanks!

The piston was damaged by spring parts that broken and one nut which was placed by old crew.

Thanks Rafiqul!

Thank you Lucas!!!!

Hello my dear friend No-load starting and capacity regulation are achieved by keeping the suction valve ring plate in the open position; the refrigerant gas thus aspired into the cylinder is not com- pressed but thrust back out through the suc- tion valve.

Please explain in detail how suction valve kept open

hello the suction valves will be kept open with help of solenoid valves from where pressure travel and change the position of rocker arm which you can see in video that moves right and left when solenoid enegizes there is a movement to left and suction valves keep open this also help to unload the system when it is nessesary all this solenoids controlled by electrical system .Such system as you can see on video we had in all stages.

Okk.. thanks

Also wondering what country you are from? Is refrigeration your trade or did you go to university to be an engineer? I would like to know how you got a job on a ship?

Hello i don't remember 404 or 407 is the freon we use! About hiw i got job on ship i have accomplished maritime academy.

As i remember by air which entered from piping.

привет, возможно, у вас проблема с клапанами на втором ступени. какова температура воды? Попробуйте протестировать работу только с первым ступени!

Yes you need to remove the pistons so you will have a better view of what is going inside. After removing the pistons you will have more space to work and examine.It is essential to do such job because you can see all the parts the rod the piston rings and any cracks. Also you will see more details and the condition of crankshaft.

@@Adventure-Story oh.thanks for your prompt reply.gr8ful.but as mentioned,my3rd stage not working,means100%,so for that i will remove the pistons,got it.but how you are going to test the arm after installing,any tools or any device to manufacture?as it operates by hydralic ?!

@@vivekkumar-vi1sw hello dear friend as I seen and if remember correct the stages activated after the solenoid is active.There some small piping where you can blow air to see if your spring and mechanism are working and change position. Most common this springs are broken.After overhauled probably you will find some pieces on oil sump or on top of pistons. Also if you see any marks on top of pistons means that something broken. Very important is to place properly the springs. Please refer with our founding! Check also if you Solenoid coil are working.

@@Adventure-Story spacibo...thanks so much.good day.

Hello Ice Kool i will try to do everything is possible! Thanks!

hi sir, im facing the same problem now with high suction pressure. did you manage to solve it ? many thx for your feedback

How many evaporators do you have? Freon shoud be without bubles in sight glas after condenser. Boiling temperature 5-8 degres C. Check that all stages are working, use air recirculation if available. Normaly 2 stages are sufficient for cooling. Dont forget about condenser pressure normal 15-20 bar

Before overhauling was working?

Hello springs and valve must be inspected in any case you find any damage to any parts better to replace them with new one.

Hello yes you can do it!

Hello Ice Kool i never have worked with Yanmar i have listed that this kind of diesel generator are good but if you have any material to see it is welcome! Thanks

Hello dear friend check that the solenoid for loading and unloading stages are working properly and not have any malfunction.

I already check na solenoid and replaced with new one but the problem still there the suction pressure always flactuate back and forth from 4bars to 9bars and somethimes going higher and higher...the casing of compressor going hotter and hotter till going to smoke..

The freon level is correct in the system or it is over capacity?Normally pressure aŕe almost steady. Check also cooling of condenser if it os correct.Please inform if you find any other problem.If you have remove amy insulation put it back.And describe how this happen aftwr overhauling?

Sometimes the compressor worked properly and I got 4bars suction pressure and 17bars discharge pressure and reaching the cut off mode and stop the comp...but when cut in is activated and automatic start the compressor then that's the time the problem of suction pressure back to fluctuating again and again from 4bars to 8bars sometimes more and more until the compressor going hotter and hotter...i dont know really the problem sir...

@@enriqueballicud7461 hello all the other parameters are fine? Maybe the problem is from Superheat hunting is a cyclical fluctuation in suction superheat due to varying refrigerant flow rate in the system. Superheat hunting is the result of the expansion valve excessively opening and closing in an attempt to maintain a constant operating condition. I am Wait for your findings!

Hello for electrician part you can measure in there is any voltage when activated by meter and the mechanical part can be tested by air blowing through the piping.Also when the system are working you can test all the stages and have a record.Before any overhaul record the parameters so you can compare later on.

@@Adventure-Story we have a problem in our ac.its showing high suction pressure.and only one unit is working. I want to rectify this problem.capacity controller is oil pressure type. Sabroe cmo18 I think problem in the capacity controller.how to check capacity controller without dismantle and how to repair it? Please reply me soon.thank you for you explanation

If you are mean the capacity controller of stage let’s say 2 or 3 check if there is any voltage coming there!By set that stage in from panel and measure the value if there is correct output like manual says it is ok.

Looks like an hfc refrigerant.

They are different the One is Aircondition the other is Thermal Expansion Valve.

@@Adventure-Story I'm asking d same thing difference between the two TEV ?? The one used in AC & other used in reefer ?

Sorry i did get your answer normally the result must be the same .maybe they have difference in technical parameters.

@@Adventure-Story the one used in ac is generally electronic and dat used in reefer is thermal expansion valve other than dat if any difference is der plz let me know

Hello yes sure! Better email

Thanks alot! Can i have your email address? Cannot find it anywhere else in the channel

@@OnkarSingh-mf7of ok better instagram you can find it on main page of the channel and then press the icom on the right .
