1. Compressor Parts (1) of the valve spring motives ranging from the use of pitch valve spring (such as portable air compressor, screw air compressor, etc.), its purpose is when the spring is compressed, the smaller end of the pitch gradually Diego work together so that the actual number of turns of the spring is reduced, thereby increasing the stiffness of the spring and reduce the resonance occurs. During installation, you must make the pitch smaller end of vitality flat head (valve seat), otherwise prone to break at work. (2) air compressor cylinder liner cylinder liner, mostly copper - asbestos structure, installed between the cylinder head and cylinder block to seal the combustion chamber to prevent air and water leakage. In general, when the cylinder head and cylinder block with cast iron materials when the professional air compressor manufacturers, cylinder head gasket flange side should be facing the large deformation of the cylinder head and easy to trim, smooth surface toward the cylinder block is about to air compressor manufacturers offer thereby protecting the cylinder plane is not being scraped nicks, scratches leaving the cylinder head gasket to prevent burn out; when the material is aluminum alloy cylinder head, cylinder head made of cast iron, thereby protecting the plane is not being scraped engraved cylinder marks, leaving the head to prevent scratches to burn; when the material is aluminum alloy cylinder head, the cylinder made of cast iron, the cylinder head gasket should be smooth side facing the cylinder head, cylinder block flange side facing to reduce aluminum cylinder compressive marks deformation possible. When installing the cylinder head gasket, the need to pay attention to: the different types of air compressors and some have special requirements. (3) when connecting the piston and piston rod, or piston rod group on the mounting body, to pay attention to different types of air compressor piston require different methods. Improper installation can lead to poor air compressor work, or even with the valve piston or piston and cylinder head collision accident occurred. For diesel-moving screw air compressor, piston valve pits top notch and after installation should mark the relative connecting rod, and for diesel-moving screw air compressor is contrary to the above. 1, the air output temperature is too high (1) to reduce the input screw air compressor air temperature. Increase air compressor room ventilation air compressor manufacturers in the room plus roof exhaust hood, used to exclude heat, control room temperature is not too high. In summer, the air compressor room temperature should not exceed 40 ℃. (2) reduce the cooling water inlet temperature, winter water temperature maintained at 18 ℃, summer water temperature maintained at 24 ℃. (3) increase the flow of cooling water, the estimated temperature of the cooling water input and output of the temperature difference between l5 ℃, the cooling water flow rate of 3.7 liters / sec. (4) removal of the cooling water scale or dirty sediment. In the cooling water by adding detergent to clear cooling water system. 2, high oil temperature screw compressor screw air compressor air compressor manufacturers have set up to protect the oil wholesale, oil temperature exceeds 70 ℃, shut down, resulting in frequent compressor shutdown. Oil temperature is too high because the oil cooler failure. Since the cooling water circuit in the oil cooler is fine, easy to clean up after fouling, resulting in the oil temperature does not drop down. Replacing an oil cooler and too expensive. After the study explored using the following methods to clean the cooler is better. Remove the oil cooler, soaked in detergent in one day, and then a small pump water under pressure into the oil cooler repeated washing, the scale can be removed in summer to control the oil temperature below 60 ℃. 3, the air filter frequently fail to start using screw air compressor, the air filter is only one month on the failure. The analysis of ambient air is dirtier. For this reason above plus access cover on the air compressor air filter, longer filter life. 4, screw air compressor screw air compressor motor burned frequently during use, the main motor frequently burned over a period of time. The main reason is that no one thing has its maximum operating pressure, and over the working pressure and long-running, long-term overload, it will cause the compressor motor overheating, burning motor.
