Working criteria, oil-free screw air compressor belongs to miniature reciprocating piston compressor. The motor is driven by a symmetrically distributed crank rocker mechanically constructed single axis. The main movement is paid as a piston ring, the auxiliary movement is paid as the surface of an aluminum alloy cylinder, and the movement between the pistons is paid. The ring is self-lubricating and does not add any lubricant.
　　
　　Outline the principle of operation, the piston is self-lubricating through piston rings without the addition of any lubricant. The compressor periodically changes the volume of the cylindrical cylinder by the reciprocating movement of the crank rocker, and the cylinder volume changes twice in the opposite direction. When the positive direction is the cylinder volume expansion direction, the cylinder volume is vacuum, the atmospheric pressure is greater than the cylinder air pressure, and the air enters the cylinder through the gas valve. At this time, the suction process: when the reverse is the direction of volume reduction, the gas entering the cylinder is compressed, and the pressure in the volume increases rapidly. When it is greater than atmospheric pressure, the exhaust valve opens, which is the exhaust process. The single-shaft and double-cylinder structure makes the compressor gas flow rate twice that of the single cylinder when the rated speed is constant, and the vibration and noise generated by the single-cylinder compressor are well solved, and the overall structure is more robust and compact. The working principle of the whole machine, the air enters the compressor from the intake pipe, the rotation of the motor makes the piston reciprocate and compress the air, so that the pressurized gas enters the gas tank through the gas outlet through the high-pressure hose, and the pressure instrument pointer display rises to 8BAR. , greater than 8BAR, the pressure switch automatically closes, the motor stops working, and the solenoid valve reduces the air pressure in the compressor head to 0 through the depressurizing air pipe. At this time, the air switching pressure and gas pressure in the gas storage tank are still 8KG, and the gas passes through. Filter pressure regulating valve and exhaust switch exhaust. When the air pressure in the air tank drops to 5kg, the pressure switch opens automatically and the compressor starts working again.
　　
　　Why should the compressor be stopped urgently? Such problems will inevitably occur during the use of the compressor. Although this is a minor issue, it does not make the compressor function properly. It's a headache. We often overlook this little problem. When the exhaust temperature exceeds 100 degrees Celsius or the motor load, the motor will start the protection device, the overcurrent protection device will automatically cut off the power supply, and the control panel will display the overload alarm. At this point, we must deal with it immediately. If improper handling will cause the compressor motor to burn out, the motor will stop immediately, the exhaust valve will open, and the intake valve will be closed, preventing the coolant from continuing to drain from the compressor. Emergency stop is possible only if the device has an exception during operation. If this is not the case, an emergency stop is not allowed. Otherwise, the system may fail or liquid may be ejected from the air intake.
