Compressor diagnosis?
"axolotl" wrote in message
... The patient is a Sears compressor- really a relabeled Campbell Hausfield VT200001; two cylinder, 2 HP, 20 Gal tank. The unit pumps up and shuts down as it should. Air is leaking, from the sound of it, at the reed valves. The tank pressure drops. My guess of the moment is that the check valve on the tank is leaking. Is my logic flawed? Thanks, Kevin Gallimore Probably gunked up . They can be cleaned , sometimes . Not all that expensive if it needs replacing . -- Snag |

Instead of emitting a single, short burst of air upon shutdown, air will continue to be expelled from the unloader vavle at the pressure switch if the check valve is failed. Is my logic flawed? Nope. Thanks, You're perfectly welcome. A lot of times you can pull the check valve out and clean it and or otherwise kludge some sort of temporary fix to get you by till a new one arrives. |

I don't know about Kevin's cheap air compressor, but my cheap air compressor does not have an unloader valve -- it just has a leak on the compressor side, and a check valve. I figured this out because when I got it the thing wouldn't start against pressure. After puzzling over it and a bit of checking, I found out that someone had taken the ball (but not the spring) out of the check valve. Fortunately, we have some little ball bearing and magnet toys; the kids did not notice one ball bearing fewer, and now my compressor works fine. -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com |

Thanks, Kevin Gallimore Ayup. Sure sounds like it. -- ""Almost all liberal behavioral tropes track the impotent rage of small children. Thus, for example, there is also the popular tactic of repeating some stupid, meaningless phrase a billion times" Arms for hostages, arms for hostages, arms for hostages, it's just about sex, just about sex, just about sex, dumb,dumb, money in politics,money in politics, Enron, Enron, Enron. Nothing repeated with mind-numbing frequency in all major news outlets will not be believed by some members of the populace. It is the permanence of evil; you can't stop it." (Ann Coulter) |

Speaking of balls, my Gardner Denver uses a ball as an outlet valve. When I first got it the ball was somewhat corroded but a visit to my friendly auto mechanic produced a suitable replacement. --- Gerry :-)} London,Canada |
