MS111 – Test bench for diagnostics of vehicle air conditioner compressors
Checking the car conditioner
Today, axial-piston compressors with wash plates are one of the most common types of compressors installed in automotive climate systems. Regardless of the compressor type, the condition of oil in the crankcase should be assessed prior to launching the diagnostics of the unit. To obtain an oil sample it is necessary to unscrew the tap screw in the compressor crankcase or simply to drain the oil through high and low-pressure ports.
Transparency of the oil with a slightly green fluorescent liquid is indicative of the good condition of the compressor piston group. On the contrary, if the oil is gray or contaminated with metal shavings, the compressor should be disassembled and repaired. If this is the case, no preliminary diagnostics is required. Before the compressor installation, the system should be flushed directly in the car. Flushing Stand for AC systems MS101P will provide quick and quality cleaning of the AC system pipelines from contaminations.
