Inverter air compressor systems, its main function is to save energy. So the drive is from what to play a protective effect on the motor it? Here we will analyze the answers to this question. Drive to protect the motor are mainly the following aspects: over-voltage protection, under-voltage protection, over current protection, lack of protection, Reverse polarity protection, overload protection, ground fault protection, short circuit protection, overclocking protection and stall protection. Below these types of drive motors for protection a simple introduction. 1. Overvoltage protection: the inverter output voltage detection function can automatically adjust the output voltage of the inverter, the motor is not withstand overvoltage. Even when the output voltage and output voltage adjustment failure more than 110% of the normal voltage, the inverter will stop the motor through the protective effects. 2. Under-voltage protection: When 90% of the motor voltage is lower than normal voltage inverter protection shutdown. 3. Over-current protection: When the motor current exceeds 150% of the rated / 3 seconds of air compressor manufacturers supply, or 200% of rated current / 10 microseconds, by stopping the drive to protect the motor. 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.) air compressor manufacturer Which is good, its purpose is when the spring is compressed pitch smaller end gradually laminated so that the actual work of reducing the number of turns of the spring compressor manufacturers, thereby increasing the stiffness of the spring and reduce the resonance occurs. When installing air compressor manufacturer direct, you must make the smaller end of the pitch plane energetic 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, the cylinder head gasket flange side should be facing the large deformation of the cylinder head and easy to trim, smooth side facing the cylinder block is about to protect the cylinder plane will not be 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 cylinder plane is not being scraped notch, leaving the head to prevent scratches burn; when the material is aluminum alloy cylinder head, 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 indentation 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.
