The Komatsu - 7 main air conditioner compressor is made of high-strength aluminum alloy with an anti-corrosion coating, providing a cooling capacity of 7.5 kW. The compressor cylinder diameter is 45 millimeters, and the piston stroke is 60 millimeters. The standard operating pressure is set between 0.8 and 1.2 MPa, and the input motor speed is 3000 RPM. The internal lubrication system with a high-pressure pump of 0.5 liters per minute ensures proper lubrication of the piston and crankshaft. The operating temperature ranges from -20 to 120°C, and the noise level does not exceed 72 dB.
The compressor crankshaft is made of hardened steel and can withstand torque up to 150 Nm. The piston rings include two compression rings and one oil ring, installed with a precise 0.02-millimeter gap to minimize leakage and maximize efficiency. The compressor undergoes pressure and vibration performance tests according to ISO 1217. All internal components are protected with anti-corrosion and heat-resistant coatings to ensure durability and reliable operation.
