1. How to improve the compressor’s exhaust volume?
To improve the compressor’s exhaust volume (gas delivery) is also to improve the output coefficient, usually using the following methods.
(1). Correctly select the size of the clearance volume.
(2). Maintain the tightness of the piston ring.
(3). Maintain tightness of gas log and stuffing box.
(4). Maintaining the sensitivity of the suction generation and exhaust logging.
(5). Reduce the resistance to gas intake.
(6). Dryer and colder gases should be inhaled.
(7). Maintain tightness of output lines, gas logs, storage tanks and coolers.
(8). Increase the speed of the compressor as appropriate.
(9). Use of advanced cooling systems.
(10). If necessary, clean the cylinder and other parts of the machine.
2. Why is the exhaust temperature limit in the compressor very strict?
For the compressor with lubricating oil, if the exhaust temperature is too high, it will make the lubricating oil viscosity decrease and the lubricating oil performance deteriorate; it will make the light capital fraction in the lubricating oil volatilize rapidly and cause “carbon accumulation” phenomenon. The actual proof, when the exhaust temperature exceeds 200℃, the “carbon” is quite serious, which can make the channel of the exhaust valve seat and spring seat (valve file) and the exhaust pipe blocked, so that the channel yin force increases; the “carbon” can make the piston ring stuck in the piston ring groove, and lose the seal. Role; if the role of static electricity will also make “carbon” explosion, so the power of the compressor water-cooled exhaust temperature does not exceed 160 ℃, air-cooled not more than 180 ℃.
3. What are the causes of cracks in machine parts?
(1). Cooling water in the head of the engine block, not drained in time to freeze after stopping in winter.
(2). Due to the internal stress generated during casting, which gradually expands significantly after vibration in use.
(3). Due to mechanical accidents and caused by, such as piston rupture, connecting rod screw broken, resulting in broken off the connecting rod, or the crankshaft balance iron flying out to break the body or gas log in the parts off the top bad cylinder head, etc..
