Compressor Overview Air compressor, air compressor full name, is an industrial and mining enterprises of the most commonly used air power to provide equipment. Typically, the air compressor into screw air compressor, piston compressor and so on.
Screw Compressors Work Screw Compressors parallel to each other by a pair of meshing rotors of yin and yang (or screw) in the cylinder rotation, the air between the rotor groove continuously produce periodic changes in the volume of air is along the the rotor axis by the inhalation side of the conveyor to the output side of the screw air compressor to achieve suction, compression and exhaust the whole process. Air compressor inlet and outlet were located at both ends of the shell, negative conversion sub-slot, and Yang was the main rotor tooth Motor Drive the rotation.
piston air compressor works Piston compressor is the motor drive pulley directly driven through the coupling crank, connecting rod and rod drive, so that the piston within the compressor cylinder for reciprocating motion, the completion of inhalation, compression, discharge and other process, there will be no pressure or Low Gas boost, and output to the storage pressure tank. Among them, the piston assembly, piston and cylinder wall and cylinder head form a variable volume working chamber, the connecting rod driven in the cylinder for reciprocating motion in order to achieve compression of the gas cylinder.
Air compressor system control Main air compressor motor operation mode for the stars - after the starting horn buck running full pressure, the specific work flow for the gas supply system: When you press the start button, the control system connected to starter coil and open the shutoff valve, air In the unloading mode, press start, then the intake valve in the closed position, the release valve opens to discharge oil separator pressure. So buck n seconds (the time Relay Control) to run after the compressor start loading, the system pressure begins to rise. If the system pressure rises to Pressure Switch Upper limit, that is, take off the pressure, the controller so that the intake valve closed, put oil and gas separator gas compressor load operation until the system pressure drops below the lower limit pressure switch after that jump back under the pressure of the inlet valve controller open, oil and gas separator release valve closed, open the compressor, oil separator air release valve closed, the compressor runs fully loaded.
Energy Saving Air Compressor System In pipeline gas supply system, the basic object is the flow control, gas supply system's basic task is to meet the needs of the user traffic. At present, the common gas flow control methods are loading and unloading gas control and the two speed control mode.
loading and unloading gas control loading and unloading gas into the valve control mode shall switch control methods, namely, the upper limit of the pressure off valve to the compressor into the light-load operation; pressure reached the lower limit of open valves, compression machine into full run.
As air compressor can not be excluded at full load condition the possibility of long-running, it can only be required to determine the maximum capacity of the motor, the design margin generally too large. Frequency starting equipment, the impact of large motor bearings wear large, so large amount of equipment maintenance. Although there are step-down start, but the start when the current is still large, will affect the grid stability and Other The safe operation of electrical equipment, and most are run continuously, due to the general air compressor drive motor itself can not speed, and therefore can not directly use the changes in pressure or flow to slow down and adjust output power to achieve the matching, the motor does not allows frequent start, resulting in less gas consumption when idle motor still running, a huge energy waste.
Often unloading and loading of the entire gas network pressure constantly changing, can not maintain a constant working pressure to extend the life of the compressor. Some of the air compressor conditioning methods (such as regulating valves or adjust the unloading, etc.) even if the required flow is smaller, because motor speed constant, the electrical power is relatively small decline.
speed control That by changing the compressor speed to adjust the flow rate, and the valve opening remains the same (generally maintain maximum opening). When the compressor rotational speed changes, the gas supply system of the lift characteristics and changes, and change management resistance characteristics.
In this control mode, by changing the frequency control technology air compressor motor speed, air compressor gas flow can be used as the gas flow is changed to achieve a real balance between supply and demand, while in energy-saving also make the whole system to achieve optimum efficiency. Inverter AC has an AC power supply based on transformation theory, can control the needs of the target output continuously adjustable frequency AC voltage. Frequency proportional to motor speed and power, therefore, with the inverter output frequency AC voltage adjustable power supply voltage as the compressor motor, air compressor can easily change the speed. Energy Saving Air Compressor System Principles
Air compressor with inverter speed control to achieve energy efficiency is a more scientific control. Operating characteristics under the air compressor to know:
Q1/Q2 = n1/n2 H1/H2 = (n1/n2) 2 P1/P2 = (n1/n2) 3 Type in the Q??? Air compressor air flow supply pipe network;
H??? Pipeline pressure; P??? Motor power consumption; N??? Compressor speed. From the above equation, when the rated speed of the motor speed down to 80% of the supply pipeline compressor air flow reduced to 80%, reduced the pressure pipe (80%) 2, the electrical power consumption is reduced ( 80%) 3, or 51.2%, removal of electrical machinery and motor copper loss and iron loss and so the impact of energy efficiency close to 40%, which is where the principle of speed control.
Long proved, in the gas supply system with a variable frequency energy systems, using frequency conversion technology to change the compressor speed to regulate the flow of the pipeline to replace the valve control mode, can achieve significant energy savings, the general Saving Rate above 30%. In addition, the frequency converter and soft-start function enables smooth speed control characteristics of a smooth adjustment of the flow, while reducing the impact and start to extend the service life of units and control group.
Compressor frequency transformation program Frequency Conversion Air Compressor Note 1) air compressor is a great moment of inertia of the load, this can easily lead to start the characteristics of V / F control mode of inverter overcurrent protection start jumping when circumstances suggested the use of non-high starting torque speed Sensor Vector converter, which can achieve constant pressure to ensure continuity of supply, but also to ensure stable and reliable operation of equipment;
2) air compressor does not allow a long run in the low-frequency, low speed when the air compressor, air compressor will work on the one hand the stability of variation, on the other hand also worse cylinder lubrication will accelerate wear. And so the minimum frequency should be no less than 20Hz
