Compressor fault

[carbon]

Oil levels ok, quite often there’s an arrow on the pump showing the correct direction of rotation

Sorry beat me to it

Try to find out from Abac if the oil level is OK. On my Clarke the correct level is on the red dot, on my SIP it's at the top of the sight glass.

The copper pipe from the pump will got hot enough to give you a burn, that's quite normal.

have we decided if it now single or three phase ?
electricians ( sorry brightspark but its true ) very often wire compressors up, to drive the wrong direction

quite a lot do . they don't understand machinery or how it works or its implications - some old compressors have a scoop on the crank that picks the oil up and splash feed the barrels pistons and small end bush running the wrong direction and they don't work along with the cooling fan -pulley to cool the cylinder

Thanks for that will check it out tomorrow cheers .

It's single phase it was 3phase but I changed the motor and now the switch

Yep been to quite afew overheating at best rattling at worst

and the 'electrian ' left the three phase OL in?? ? HUM
it still can be turning the wrong direction though

Oil level is OK if you look on the compressor fly wheel it should have a directional arrow cast into it,(most but not all do).

Can't see a arrow showing direction of motor , will strip the plastics of ot at weekend and get a better look ,is it possible I've wired it wrong ,the new switch I got had no wireing diagram, many thanks .

How do I check , if there is no direction arrow on the motor , the large wheel where the belt goes round on the pump is like a fan blade just now its pulling air threw from the cylinder head side ,I thought it should blow air onto it to cool it down ,that's why I was asking if the motor is going wrong way ,thanks guys .

Just never noticed it hot before it is hot enough to burn the cylinder head is hot aswell ,thanks

If there isn’t a direction arrow on the pump pulley is it marked on the belt guard. I think that’s were mine is marked.

It should blow air towards the pump.

You can't reverse the motor from the switch wiring, you need to take the lid off the terminal cover, there should be a diagram in there to show how to wire the motor depending which way you want it to rotate.

 

[pauliil1948]

Thanks for your help its now sorted I changed the wires and now runs the correct way , and fitted new pressure switch and it's all good and working fine ,many thanks to all you guys for your help ,your all at the top of my Xmas card list

Thanks for letting us know
