Problem with a Rotary Screw Compressor

When we turn off the compressor, takes like 7 secons to discharge, then the engine automatically shut down, but at this moment for some reason the coolant comes out of the unit through the inlet valve.

We suspect that have to be a discharche valve or something like that, but we could not found it.

Compressor shuts down and will not allow enough pressure run machine


Sounds like the oil is low or the cooler is dirty. If that's not the case then you have a defective thermal valve.

After running for a few hours it gets hot and shuts down but runs fine every morning


Without more info I will have to give you several things to look at. Typically during the hot months rotary units experience temperature shut downs due to the following. Dirty oil coolers. Blowing them out with air my help some but ideally they need to be washed using a degreaser solution. Location. during the hot months poor air flow/ air removal may let heat from the compressor build up in or under the cover or room. This hot air gets drawn in by the compressor and raises the compressor temperature. The cycle continues until the compressor shuts down on high air temp. Maintenance. Poor maintenance on rotary screw compressors leads to shut downs on high temp, high air temps then play havoc on dryers which causes moisture in the air system. Maintenance items that need replacing regularly ( about 2000 hrs) oil filter, air filter, Depending on type of oil used change 2000 to 8000 hrs, seperator @ 8000 hrs. Also the amont element will cause high temps if bad. It is located where the three oil lines come together. There should be 4 screws that hold the cover on. the cover also has a hose connected to it and located close to the oil cooler. This amont element acts like the thermostat in your car. it lets oil bypass the oil cooler or causes more oil to go thru the cooler. the cooler oil and bypass oil mixes and maintains a certain temp. air end temp should run about 195 F and injected temp about 165 F. hope this helps. if you can give more detailed info I can get you closer to your problem.

Gardner denver air compressor is blowing oil, need help


Is this a rotary screw compressor? If so, is it blowing oil out of the air filter or out of the discharge air lines? If it's blowing oil out of the air filter you have a oil stop valve or minimum pressure check valve bad. If oil is coming out of the discharge air you need to change the seperator.

1989 Ingersoll Rand 185 diesel compressor shuts down under load


most have safety shut downs built in, on the compressor side you will have a high discharge temp shut down, usually set to shut down @ 230 degrees F. normal temp should be @ 180F if it is running hot first check oil level on the compressor, and that the radiator is clean. some machines will have a thermostat that will only allow oil flow to go to the radiator after it comes up to about 150 degrees F. you really need to have a manual on the machine to see what other safety's it may have on the compressor and engine side as well.

My rotary screw air compressor model SSREP100H


It's just too hot. Blow out the radiator weekly. There is an oil temp switch that might need replaced but the radiator is the most common problem with screw compressors. You can check the settings in the control panel, where you turn it on and off. It should be set for a high temp of 185°.

1989 Ingersoll-Rand 185 cfm air compressor will not build up air


ITS A POSSIBILITY AND YOU BETTER HOPE ITS NOT SPINNING BECAUSE THE SCREW COMPRESSOR IS LOCKED UP. CHECK THE OIL LEVEL IN THE SUMP AND SEE IF THE ROTOR WILL TURN WHEN NOT RUNNING. TYPICALLY THE DIESEL ENGINE WILL TURN HIGHER RPMS WHEN IT HAS NO DRAG ( NO COMPRESSOR HOOKED UP ). YOU CAN GET THE PARTS FROM INGERSOL RAND OR ANY RENTAL YARD - UNITED, PENSKE, SUNBELT, ETC. THEIR MECHANIC SHOPS ARE USUALLY FOR HIRE AND CAN EVEN INSTALL IT FOR A CHARGE. ALSO MAKE SURE NOTHING BUILT A NEST IN THERE. IF YOU REMOVE THE SCREW, MAKE SURE AND WATCH FOR SHIMS. THOSE SHAFTS NEED TO LINED UP PERFECT TO REDUCE VIBRATION. GOOD LUCK
