Open Question

Gents; We have SSR 100HP Ingersoll rand (watercooled) air compressor and it is not giving high pressure (low pressure =0.5 bar only). We changed the Unload/Load valve and checked again but we have same problem. We checked if the pressure line of the solenoid valve and found that there is no air supply to this valve. please advice where could be the problem? Thanks in advance. Mohammed Alhajri

SOURCE: I HAVE AN INGERSOLL RAND

I know you have checked voltage. However please remove the fuses for control power and check,also check fu4 and 5 16volt fuses. next check power on the controller input. Don't remember terminal # but if you look in electrical cover removed to gain access, a wiring schematic will be affixed to it. I think it's on j5 terminal 36 110volts. But please check the schematic first. If you have power at the input terminal I suspect the controller is bad but continue with the following checks. If no power at terminal 36 check the hat (High Air Temperature) switch. Its located on the end of the airend and about 1/2 inch flex connected.If the hat switch is good check the emergency stop contacts. Note the power lite picks up voltage before the emergency stop and hat switch. So even though the lite is on one of these switches may be bad.

SOURCE: What does alarm start fault

I use to start up a 25 HP Ingersol screw type compressor. The only alarms I got were from power spikes which just needed the reset button to be pushed, then the on button - and the low oil sensor would shut it down and give an alarm when the tank was about half way down. They will blow up with no oil so there is a saftey margin on oil level.

My ssrxpe60 ingersoll rand compressor is giving a high air pressure alarm and shuts down


I may be missing something here but typically a SSR is a rotary screw machine.XPE 60 is the model. It probably has a controller of some type for this person to know its shutting down on high air pressure alarm. So as the previous person kindly said don't give advise on something you know nothing about before you get some one hurt or killed!!!!
To answer the question. You may have a pressure transducer bad but most likely you have a minimum pressure check valve stuck in the closed position. When the compressor starts air pressure in the separator tank builds. At approximately 65 Psi the MPCV opens and allows air to the after cooler and out into the system. If the MPCV doesn't open the air pressure in the separator tank becomes to high. You then get the high pressure alarm and the unit shuts down.
Make sure the air pressure is zero, electrical disconnected and discharge line isolated from system. Once done you should be able to unscrew the aluminum cap on the check valve. Be extra careful due to spring tension. It should loosen as the cap is removed. If the parts inside are very corroded or you are unable to remove the cap you may have to replace the complete valve. If able to disassemble clean and purchase a rebuild kit for your MPCV if available.

WHY DOES A SM75 INGERSOLL RAND COMPRESSOR CUT OUT ON LOW PRESSURE OIL


Low oil pressure. Are you adding a lot of oil. Have you check the oil level. Switch could also be bad.

Make sure the model of your compressor is design for 160psi if not the main motor trip off and safe valve pop. Goto Main Menu, Operator setpoint+select, Offline/Online+select, arrow up and down to change value.

replace the hat switch. hat = High Air temp. This switch is located on the end of the air end and usually has 1/2" flex conduit on it. Remove the conduit. It goes to a box located on the frame near and under the airend. Remove the cover from the box tug on the wires at the hat switch to see which two wires need to be disconnected.disconnect wires unscrew hat switch. Put a new oring on the new hat switch and install new hat switch. Hat switch is the only switch that will give high temp and lose control power. Let set a while and can reset unless probe is broken off.

Cuts off with no reason


hi mate when the reach there working pressure e.g.150psi/10bar they shut off and then when the pressure drops to a pressure of e.g. 100 psi 7 bar they automatically start back up and pump back upto they working temperature or if it dont start at all it could either be a faulty pressure switch or a fualty star delta starter if its 3 phase 415 volts if its 240volt there are only a pressure switch which will be faulty get a sparky in to sort it out there buggers to mess with 415volts 240 volts easy
