any body please

we have many compresors with the union rods broken, the units are "carrier" 50 tj on 25 ton. 480 volts.we´v changed 15 (12.5ton.)compresors of 67 units that mean a very big problem on units, just broken like pop corns, we would thanks if a recomendation arrives as. thank´s

What do you mean by "union rods"?

[mdp]

If what you mean are the connecting rods (those thingys that go between the piston and the crank) only one thing will cause them to break. If they are indeed actually breaking in pieces it's what we call hydrostatic lock, when the cylinder fills with liquid and then you try to turn the crank. Before the liquid can snap the valves the rod breaks, you can't compress a liquid. If it the bearing on the crank end of the rod that's going out you have a liquid flooding problem. Either way you have a problem with liquid in the wrong place. If you have more details I'm sure you'll get your answer.

"hydraulic compression"

[DrFreeze2000]

If you are loosing that many compressors in 'different' units at the same location I would investigate EMS, airflows, T&B, and those pesky filter changers dudes.

I believe all TJ's over 7.5 tons are txv, been a couple years for me on package Carrier, but even low airflow on these units (within reason) should not be bustin' up green pumpers.
