see API 618 description
the head doesnt effect the output pressure of a compressor package but the size of the piston and the amount of clearence and volume between the piston and head changes your output psi
a single stage compressor only compresses once while a double stage will take the volume from the first stage and compress it more. Makes more pressure but less volume

The bar-over test for a compressor, often referred to as the "bar-over" or "over-bar" test, is a diagnostic method used to evaluate the performance and efficiency of a compressor. This test involves measuring the pressure differential across the compressor to determine its ability to maintain proper pressure levels under load. By analyzing the results, technicians can identify issues such as leaks, wear, or operational inefficiencies that may require attention. Overall, it helps ensure the compressor operates within its optimal performance range.
I'm in the process studying for my epa test and this is one of the questions and their answer is foaming occurs in the compressor.
If the compressor doesn't start remove all the relays and circuitry installed on it and measure the resistance of the windings A video detailing the process can be found in related links.
Yes. A megohm test is a way of determining the condition of the compressor's winding insulation. If the insulation is deteriorated or beginning to deteriorate, a megohm test will show this. Generally speaking, 20 megohms or less shows bad motor winding insulation. When AC voltage is applied to a compressor that has bad windings, it will likely blow a fuse as it will short to ground. Moisture in the system can cause a false megohm reading. Also, it is not advisable to test a system that is in a vacuum, as this also can cause a false reading. If a compressor is grounded, a regular multimeter set to ohms will determine this (one probe on any of the compressor terminals and one to the discharge or suction line pipe). A megohm meter will show that a problem is eminent even if the compressor is not yet fully grounded and blowing fuses.
With an ohm-meter. Check for continuity in the RUN and START windings, and also from the terminals to compressor case for shorting. There should be continuity in the windings and no continuity from windings to compressor case.
just disconnect power & get ur Ohmmeter,and test ; Start-Run//Common-Run//Common-Start..... you should get the same readings on all 3 phases if the compressor is good !!
To fix the AC compressor on a 1990 Mazda Miata, first, disconnect the battery and remove any components obstructing access to the compressor. Check for leaks and test the electrical connections; if the compressor is faulty, it may need to be replaced. Remove the old compressor by detaching the refrigerant lines and mounting bolts, then install the new compressor, reconnect the lines, and recharge the AC system with refrigerant. Finally, reconnect the battery and test the AC system for proper operation.
