Speedaire Compressor Problem
Hello Bill answers... Hi Marco...thanks for writing in. When you say your compressor is running, by that, do you mean that the motor is running, or that you can hear the compressor pump running as well? Does the compressor pump get hot? If the compressor motor is running, and the compressor pump is being driven by the motor (the shaft hasn't uncoupled in some manner) and the compressor pump is working properly, then you are likely pumping air into the tank, but it's getting out somewhere. Are you sure that the tank drain valve is securely shut? If it's open, just as fast as air is getting into the tank from the compressor running it's leaking out the drain, and with the noise from the compressor, you can't normally hear the leak. Once you've checked that, make sure that there's no air leaking out anywhere else...from the discharge port, for example. No leaks? Darn, that would have been an easy solution. Is the compressor sucking in air? On the top of the pump their will be an inlet for air, usually through some sort of plastic housing. That housing should screw out. Do that, and carefully feel near the hole while the compressor is running. Careful! The head will be hot. What you want to do is try to determine if air is getting pulled into the compressor. Or worse, if air is blowing out that intake port. If air isn't getting pulled in, then it might be the valve inside the head that's causing the problem. Failing that, then you may have a problem with the innards of the compressor pump. If the seals around the piston are worn to the point they can't stop air bypassing the piston, it's pretty hard for the head to pump air into the tank. It's pretty hard to figure out just what the problem is from afar. I hope this helps. Visit the home page and click on the Speedaire link from the Nav bar if you want to find your local Speedaire / Grainger location, and also click on the Repair button to see the listing of repair shops in the hopes that there will be one near you that you can take your compressor to if you feel that the repair is beyond your capability. Cheers, Bill
