                              風機水泵智能節電控制裝置
                              Intelligent electricity-saving control device of fan and pump
                               
                              風機和水泵是目前工業現場中應用較多的設備,而且電機功率較大。多數風機水泵依靠擋板、閥門來調節流量,當工藝需求變化時,風機擋板、水泵閥門開度增加或減小。該種調節方式簡單易行,但它是以增加管網損耗,耗費大量能源在擋板、閥門上為代價的。另外在通常設計中,用戶配用電機的設計容量都要比實際需求高出很多,也就是大馬拉小車現象,造成能量的極大浪費。
                              Fans and pumps are the equipment finding wide application in industrial sites, and their motor powers are huge. Most of fans and pumps rely on baffle and valve in adjusting the runoff. When technical requirement changes, baffle of fans and valve of pumps are increased or decreased in their openings. The adjustment way is simple and easy, but at the cost of increasing the energy consumption on baffle and valve. In addition, the designed capacity is usually much higher than the actual need, which results in serious waste of energy.
                               
                               
                               
                              工作原理 Working principle
                               
                              在通風或供水系統中,風機和水泵的功率都是根據最大流量來選擇的,但實際使用中流量隨各種因素而變化(如季節、溫度、工藝、產量等等),往往比最大流量小的多。要減少流量時,通常情況下只能調節擋板或閥門的開度,即通過關小和開大閥門/擋板的開度來調節流量。擋板、閥門控制法的實質是通過改變管網阻力大小來改變流量,而這種控制方式當所需流量減少時,壓力反而會增加,故軸功率的降低有限,此時,過剩的風機、水泵功率將導致壓力增加造成很大的電能損耗及加快設備損壞。
                              In ventilation or water supply system, the power of fan and pump are determined according to the maximum runoff, but the actual runoff changes frequently because of various factors (such as season, temperature, technique, and output), usually much lower than the maximum runoff. When the runoff has to be decreased, users can only adjust the opening of baffle or valve in normal cases, namely increasing or decreasing the opening of valve/baffle to adjust the runoff. The baffle and valve control method is substantially to change the runoff through the change of network resistance. But when the runoff is decreased, the pressure may increase on the contrary. So the decline of axial power is limited. At the time, surplus power of fan and pump will lead to the increase of pressure, further increasing electricity consumption and accelerating equipment failure.
                               
                              節電原理 Electricity-saving principle
                              風機水泵智能節電控制裝置可以隨工藝的需求實現動態調節,自動輸出最優的工作參數,達到工藝需求的流量和電機的輸出功率精確匹配,從而取代原有的檔板和閥門調節,可節約大量的能源。這種控制方式可從根本上消除風機、水泵設備由于選型或負荷變化普遍存在的 “ 大馬拉小車 ” 的動力浪費現象,消除了擋板、閥門節流阻力,使風機、水泵始終運行在最佳工作狀態,提高系統的穩定性和運行效率并大幅度減少能耗,降低企業生產成本。
                              Intelligent electricity-saving control device of fan and pump can be adjusted dynamically according to technical requirements, automatically generating the optimum working parameters, reaching precise matching between the flow required by the technique and the output power of motors, thus replacing the original baffle and valve adjustment and further saving a huge amount of energy. The control way can fundamentally eliminate the power waste caused by the model selection or load change of fan and pump, and the throttle resistance of baffle and valve, thus making fan and pump always work at the optimum status, increasing the stability and operating efficiency of the system and further greatly lowering the energy consumption and reducing the corporate production cost.
