1, energy-consuming loading pressure to reach the desired working pressure compressor Houqin Wei, traditional control methods adopted at its pressure will continue to rise until the unloading pressure. Pressurized process, will occur more heat and noise, and then causing power loss. On the other hand, high-pressure gas before entering the pneumatic components, the pressure demand pressure through the valve, the same energy in the process. 2, unloading energy consumption when the pressure reaches unloaded, compressor unloading valve active open, the motor idling, forming a large energy consumption. Power compressor unloading of about 30% to 50% at full load, showing the traditional air compressor has a significant saving space. 3, the frequency of the main motor launch in spite of the impact of current large selection of decompression start, but the starting current is still great, big impact on the grid, as well as easy to form a grid instability affecting the operation of other electrical equipment safety. 4, the pressure instability, low degree of automation of traditional compressor bottom degree of automation, the output pressure of conditioning is to rely on the loading and unloading valves, control valve manipulation to complete, conditioning slow shake, low accuracy, the output pressure instability. 5, a large amount of air compressor equipment maintenance Frequency launch current, up to 5-8 times the rated current, the operation mode determines the loading and unloading valve must repeat the action, air compressor parts easy to aging high cost, the frequency at high speed, bearing wear big equipment maintenance volume. 6, noisy-frequency high-speed operation continues beyond the desired working pressure rated pressure compressor, repeated loading, unloading, directly resulting in the power frequency operation. Compressor means for compressing the medium of air compressors, accounting for over 90% of the total output of the compressor, the other widely used in mining machinery, chemicals, petroleum, transportation, construction, marine and other industries, its users almost covers the national economic sectors, large breadth, it is defined as a general-purpose machinery. Because of extensive air compressor applications whose failure to directly affect the daily production in many sectors. Cause of excessive compressor motor current faults and approach: 1. Motor temperature controller failure, replace the temperature controller; 2. Compressor overload fault produce custom replacement overload; 3. air inlet obstruction, the air intakes do cleaning and maintenance; 4. drive belt tension too tight, loosen the drive belt, the normal tension of downward pressure of the distance of 0.8-1.0cm; 5. air filter blockage, replace the air filter (large vacuum value so 5psi time); 6. starter poor contact, the starter contacts do maintenance; 7. oil separator obstruction, replace oil separator (when pressure is greater than 0.8-1kg); 8. No refueling motor bearings, motor bearings filling butter; 9. The ambient temperature is too high, the installation of wind tube ventilation equipment; 10. The three-phase voltage instability, under-phase voltage is too low (below 10%), it is recommended to improve the power system; 11. The motor bearing damage will strengthen the work of the motor insulation removed done processing; 12. bad motor insulation, replace the motor bearings; 13. The motor wiring loose, re-lock the motor wiring Cottle compressor |?? Air Qin Wei (certified) |. by Xianyang compressor Compressor Co., Ltd. Qin Wei. Xianyang Qin Wei Compressor Co.
