電機(jī)是一種應(yīng)用量大、使用范圍廣的高耗能動(dòng)力設(shè)備。據(jù)統(tǒng)計(jì),我國電機(jī)耗電約占工業(yè)用電總量的60%~70%。實(shí)際應(yīng)用中,我國電機(jī)的整體運(yùn)行狀況,同國外相比差距很大,機(jī)組效率約為75%,比國外低10%左右;系統(tǒng)運(yùn)行效率為30~40%,比國際先進(jìn)水平低20~30%。因此,我國的電機(jī)應(yīng)用具有極大的節(jié)能潛力,推行電機(jī)節(jié)能勢在必行。 Motor is a kind of are big, the wide use of energy intensive power equipment.According to statistics, China's electric power consumption accounts for about 60% ~ 70% of the total industrial power.In practical application, the overall health of the motor, a big gap compared with foreign, unit efficiency is about 75%, about 10% less than abroad;System efficiency is 30 ~ 40%, 20 ~ 30% lower than the international advanced level.Therefore, application of motor in our country has a great energy saving potential, promote motor energy conservation is imperative. 目前電機(jī)能耗狀況是:與發(fā)達(dá)國家相比,我國電力能源利用效率仍然較低,尤其是工業(yè)用電設(shè)備電能消耗高,浪費(fèi)情況較為嚴(yán)重。大量的工業(yè)設(shè)備如風(fēng)機(jī)、泵類設(shè)備以及傳統(tǒng)的工業(yè)縫紉機(jī)、機(jī)械加工設(shè)備等,多采用交流電動(dòng)機(jī)恒速傳動(dòng)的方案運(yùn)行,導(dǎo)致交流電動(dòng)機(jī)效率普遍較低。 Motor energy consumption is at present: compared with the developed countries, our country electric power energy efficiency is still low, especially the industrial electric power consumption of the equipment are high, waste is serious.A large number of industrial equipment such as fans, pumps and traditional industrial sewing machines, mechanical processing equipment, with ac motor constant speed transmission scheme, operation result in ac motor efficiency is generally low. 傳統(tǒng)的工業(yè)縫紉機(jī)電機(jī)是一款交流離合器電機(jī),效率僅為40~50%;電機(jī)在工作時(shí),不論縫制布料厚薄,始終全功率輸出;在縫紉機(jī)待料待機(jī)時(shí),電機(jī)通過離合器脫開負(fù)載,繼續(xù)空載運(yùn)行,造成極大的待機(jī)損耗。The traditional industrial sewing machine motor is an ac clutch motor, efficiency was only about 40 ~ 50%;Motor at work, regardless of sewing fabric thickness, always full power output;When sewing machine work on standby, motor by clutch release load, to continue running light, caused a great deal of standby loss. 根據(jù)美國能源部的一項(xiàng)數(shù)據(jù)顯示,如果采用最新的高效率電機(jī)設(shè)備和一定的變頻調(diào)速裝置來替代舊的電機(jī)設(shè)備,工業(yè)用戶至少能在現(xiàn)有基礎(chǔ)上節(jié)省電能18%以上。目前許多國家均已指定流量壓力控制必須采用變頻調(diào)速裝置取代傳統(tǒng)方式,我國也在積極鼓勵(lì)工業(yè)企業(yè)采用高效、節(jié)能的電動(dòng)機(jī)、鍋爐、窯爐、風(fēng)機(jī)、泵類等設(shè)備。目前,我國在家電行業(yè)已逐步采用變頻調(diào)速控制技術(shù)以降低能耗,而工業(yè)控制領(lǐng)域中的許多速度調(diào)節(jié)方法還停留在傳統(tǒng)技術(shù)層面上。 According to the U.S. department of energy (doe), according to a data if using the latest equipment and high efficiency motor of variable frequency speed regulating device to replace the old machine equipment, based on the existing industrial users can at least save electric energy more than 18%.Now many countries have been specified flow pressure control variable frequency speed regulating device must be used to replace the traditional way, in our country are also actively encouraging industrial enterprises with high efficiency, energy saving motor, boilers, furnaces, fans, pumps and other equipment.At present, in the home appliance industry in China has gradually adopt frequency control of motor speed control technology to reduce energy consumption, and many in the field of industrial control speed regulation method with the traditional technology level. 在工業(yè)生產(chǎn)、產(chǎn)品加工制造業(yè)中,風(fēng)機(jī)設(shè)備主要用于鍋爐燃燒系統(tǒng)、烘干系統(tǒng)、冷卻系統(tǒng)、通風(fēng)系統(tǒng)等場合,根據(jù)生產(chǎn)需要對(duì)爐膛壓力、風(fēng)速、風(fēng)量、溫度等指標(biāo)進(jìn)行控制和調(diào)節(jié)以適應(yīng)工藝要求和運(yùn)行工況。而最常用的控制手段則是調(diào)節(jié)風(fēng)門、擋板開度的大小來調(diào)整受控對(duì)象。這樣,不論生產(chǎn)的需求大小,風(fēng)機(jī)都要全速運(yùn)轉(zhuǎn),不能隨運(yùn)行工況的變化進(jìn)行相應(yīng)的調(diào)節(jié),白白浪費(fèi)了大量的能量。在生產(chǎn)過程中,不僅控制精度受到限制,而且容易造成設(shè)備損耗,從而導(dǎo)致生產(chǎn)成本增加,設(shè)備使用壽命縮短,設(shè)備維護(hù)、維修費(fèi)用居高不下。In industrial production, product processing and manufacturing, fan equipment is mainly used for boiler combustion system, drying system, cooling system, ventilation system, etc, according to the production needs of furnace pressure, wind speed, air volume, temperature indicators such as control and adjust to meet the technological requirements and operation condition.The most commonly used means of control is damper, the baffle opening to adjust the size of the controlled object.In this way, regardless of the demand of production size, the fan will run at full speed, cannot adjust accordingly along with the change of operation condition, a large amount of energy wasted.In the process of production, not only the control precision is restricted, and easy to cause loss of equipment, which can lead to the cost of production increases, the equipment service life is shortened, equipment maintenance, maintenance costs high. 泵類設(shè)備在生產(chǎn)領(lǐng)域同樣有著廣闊的應(yīng)用空間,提水泵站、水池儲(chǔ)罐給排系統(tǒng)、工業(yè)水(油)循環(huán)系統(tǒng)、熱交換系統(tǒng)均使用離心泵、軸流泵、齒輪泵、柱塞泵等設(shè)備。根據(jù)不同的生產(chǎn)需求往往采用調(diào)整閥、回流閥、截止閥等節(jié)流設(shè)備進(jìn)行流量、壓力、水位等信號(hào)的控制。這樣,不僅造成大量的能源浪費(fèi),管路、閥門等密封性能的破壞;還加速了泵腔、閥體的磨損和汽蝕,嚴(yán)重時(shí)損壞設(shè)備、影響生產(chǎn)、危及產(chǎn)品質(zhì)量 Pump equipment also has a wide application in the field of production space, numerical station, tank storage tank to the exhaust system, industrial water (oil) circulation system, heat exchange system using centrifugal pump, axial flow pump, gear pump, plunger pump and other equipment.According to different production requirements often USES the adjusting valve and return valve, globe valve throttling devices such as flow, pressure, water level control signal.In this way, not only caused a lot of energy waste, the destruction of the pipeline, valve sealing performance;Also accelerated the pump cavity, the body of the wear and cavitation, serious damage to the equipment, affect production, and threaten the quality of the products
