According to the design type, environmental conditions and operating load of compressor oil, the type of compressor oil is selected. In general, in long-term high temperature environment (%26gt30℃), L-DAB oil, high-speed water cooling or low-pressure, low-viscosity compressor oil can be used for compressors with small compression ratio.
① The output power of air-cooled piston shaft is% 26lt20KW, 32,46, 100 (ambient temperature is% 26lt- 10℃, optional 32), DAA, DAB and DAC air compressor oil; ?
② No.68 oil or100 is selected for the water-cooled piston; ?
③ Select 100, 150, 220 DAB or DAC oil by dropping; ?
④ No.32 DAG, DAH or DAJ oil is selected as the oil injection rotary type.
Air compressor is a kind of equipment used to compress gas. The air compressor is similar to a water pump in structure. Most air compressors are reciprocating pistons, rotating blades or rotating screws. Centrifugal compressor is a very large application.
Extended data:
The air compressor is directly driven by the motor, which makes the crankshaft rotate and drives the connecting rod to make the piston reciprocate, resulting in the change of cylinder volume. Due to the change of pressure in the cylinder, air enters the cylinder through the intake valve and the air filter (muffler). In the compression stroke, the volume of the cylinder decreases.
Under the action of the exhaust valve, compressed air enters the gas storage tank through the exhaust pipe and the check valve (check valve). When the exhaust pressure reaches the rated pressure of 0.7MPa, it is automatically stopped by the pressure switch. When the pressure of the gas storage tank drops to 0.5-0.6MPa, the pressure switch is automatically turned on and started.
Air compressor is the core equipment of pneumatic system and the main body of electromechanical bleed air source device. It is a device that converts the mechanical energy of prime mover (usually motor or diesel engine) into gas pressure energy, and it is a gas pressure generating device for compressed air.
