T/CCI's latest introduction to the CASE Construction product family is the QP7H15 150 cc displacement compressor fitted to the backhoe loader.
For a positive displacement compressor, the compressor power is approximately proportional to the compressor speed.
com)-- T/CCI Manufacturing strategic alliance with CASE Construction recently produced the QP7H15 150 cc displacement compressor fitted to the CASE Construction backhoe loader.
The cement sector will also contribute significantly to the positive displacement compressor market's revenues, as the widening gap between supply and demand in this sector will lead to both greenfield and brownfield investments, boosting the demand for positive displacement compressors.
Since the required compressor displacement for HC-600a refrigerant is almost double that of HFC-134a to achieve identical capacity and since the larger bore size increases piston-cylinder clearance and a small displacement compressor increases re-expansion volume, raising volumetric efficiency in small refrigerating-capacity compressors is difficult.
The VSM is a rotary, positive displacement compressor, which incorporates a main screw and two gaterotors.
