compressor noise - issues

[huskystafford]

got fridge compressor on a tank. The last 3 days, i hear noises, like I would be listening to drops of water. Those ''drops'' are faster then yesterday. Today it's like 2''drops'' per second. Anybody have a clue what could be wrong?

I am planning to buy big compressor, but I wonted to do that like in 2 months maybe...

edit: this is when air tank is full or got some air and compressor is not running.

It stops making the noise after a little while?
Do you have a check valve between the compressor and tank?

nop...

few days ago I thought I hear clock, today it sounds like something would blow up... Such a difference in speed of sound in few days.

I know I pushed that compressor to much but I would be very happy if compressor survives 2 more months...

Do you have a check valve?

 

[Robbyrockett2]

One thing you can try... roll it completely over a time or two or rock it to each side so it's horizontal for a second on each side.

Can be a temporary fix for a couple problems.

Most converted fridge compressors don't lubricate themselves, even when they have oil.

If it never stops though....piston rings may be shot.

what that means for me?
this is all i got on compressor

The noise is coming from inside the compressor right?

i think so, hard to locate exact place. But that happens when compressor is not running.

I'm gonna kill my self. I rolled compressor to left side and right side to the ground. And I turn it on when I put it back to normal position and filled my tank. Sound stopped. What the Dragon...

 

[Robbyrockett2]

Well, it looks like you have a combination safety valve and check valve. If it does it as long as the tank is pressurized then that means the check valve isn't working for sure.
You can try to clean it out first.

Lol. Like I said they don't lubricate themselves.
There's a pump mechanism for the oil but if the compressor goes in a fridge it is usually incomplete in some way because In a fridge the oil gets circulated through the lines. If it goes in a silent compressor the pump mechanism is completely assembled.
So with the fridge compressor conversion it won't lubricate the cylinder or the upper crank bearing.
So the piston rings eventually lose their seal. The popping is a back leak, or sometimes cooling down or being forced a bit at a time to push down, sticking every millimeter of travel.
Rolling it gave them oil.

Do I need to fix something or I am good to go?

Well, your check valve doesn't work... Fix it or don't, probably not really a big deal.
There's obviously been some damage done from lack of lube....nothing you can do about that.
Roll it like that once in a while, it'll help limp it through as long as possible.

Your welcome, glad to help where I can.

Can I use that compressor for 2 more months or my plans will need to be readjusted? Probably hard question to answer...

nvm: it depends of how much you spraying...5am in my defence

 

[Robbyrockett2]

Yeah, hard to say, use it as long as you can.
Make sure it has as much oil as it should also.

little update:
Was at my parents, went to see them and to have coffee while talking with them. We talked with my old man about compressor, the guy is real handy man. He tares down his bike machine(oldtimer honda 750) and put it back together with no problem. And while we talked(he was still sleapy, I woke him up) he had ''the light bulb'' moment. His neighbour has a refrigerator sitting in front of doors. So old man called neighbour and asked him what he wanna do with that refrigerator. It was meant to go on a dump but compressor still works.

So bottom line I got new compressor, if I understand usually they are all the same so mounting new one shouldn't be a problem. Meanwhile I will lubricate this one and see if it can run normally or it's damaged to much. Was also asking the same question like I did you robby about how much time I have left with my compressor and he didn't answer me until I asked him if we talking about hours,days or weeks. When I sad that, he told me that we are talking about hours if compressor is damaged.

New compressor will be ready in one hour probably. My old man is talking it down from a fridge as we speak.
