I have a 30000 BTU split, the unit runs, but my concern is the accumulator freezes
The pipes are cold but not frozen, the condenser makes a high sucking sound,
The pressure on the low side is between 6-7 bar but the high side also has the same reading of 6-7 bar, this is not normal. As it should be higher, could this be a partial blockage? As unit blows cold air. Or could there be another problem component in this unit?

6 and 7 bar? Not sure what you mean. My guages go from 0 to 400.
Either way you have a problem. Maybe a blockage, mabe bad valves on compressor.. maybe something else.

you are working in psi =60-70 psi on suction then decreases to 50 psi

If they are both at the same spot than there is a very good chance you have bad valves.

When I gassed up the unit on Thursday, the unit was running & was blowing cold, pressure was about 40-45 psi, all of a sudden the pressure dropped to 10 psi, the unit was pulling in the R22, but the pressures were equalizing, 40-50 psi.

I thought the reverse valve was the problem, I changed the reverse valve, checked my common, run & start on the compressor all OK. Now when I regas, the compressor seems as if it is pumping, gauges rise to 60psi, when I close my gauges the pressure drops to around 10 psi? Do you think it is the compressor all along?
