1、河北升降貨梯http://m.kkwl.net/電機(jī)故障,電機(jī)內(nèi)部都是由鐵芯和繞組線圈組成的,繞組有電阻,通電會產(chǎn)生損耗,損耗大小與電阻和電流的平方成正比,這就是我們常說的銅損。如果電流不是標(biāo)準(zhǔn)的直流或正弦波,還會產(chǎn)生諧波損耗;鐵心有磁滯渦流效應(yīng),在交變磁場中也會產(chǎn)生損耗,其大小與材料,電流,頻率,電壓有關(guān),這叫鐵損。銅損和鐵損都會以發(fā)熱的形式表現(xiàn)出來,從而影響電機(jī)的效率。電機(jī)一般追求定位精度和力矩輸出,效率比較低,電流一般比較大,且諧波成分高,電流交變的頻率也隨轉(zhuǎn)速而變化,因而河北升降貨梯電機(jī)普遍存在發(fā)熱情況,且情況比一般交流電機(jī)嚴(yán)重,此時應(yīng)當(dāng)及時聯(lián)系生產(chǎn)廠家或?qū)I(yè)維修人員,進(jìn)行檢修。
Shandong cargo lifter motor failure, internal motor core and windings are made consisting of windings resistance, power will produce losses, the loss is proportional to the square of the size and resistance and current, and this is what we often say that the copper loss. If the current is not a standard DC or sine wave, but also produce harmonic losses; vortex core has a hysteresis effect in an alternating magnetic field will produce loss, its size and materials,current, frequency, voltage, called iron loss . Copper and iron losses will be manifested in the form of heat, thus affecting the efficiency of the motor. Motors are generally pursue positioning accuracy and torque output, efficiency is relatively low, the current general relatively large, and high harmonic components, the frequency of the alternating current with the speed of change, and therefore the prevalence of fever Shandong cargo lifter motor case and the situation than the average exchange motor serious, this time should contact the manufacturer or qualified service personnel for maintenance.
2、河北升降貨梯油管堵塞,檢查油管是否流通順暢,液壓油流通不暢會給液壓系統(tǒng)帶來負(fù)擔(dān),使泵站發(fā)熱。
Shandong cargo lifter tubing plug, check whether the smooth flow tubing, hydraulic oil flow of the hydraulic system will burden the poor, so that the heat pump station.
3、河北升降貨梯http://m.kkwl.net/設(shè)備超載,檢查貨物是否超過額定載荷,造成泵站過熱,超載會嚴(yán)重影響使用壽命。
Shandong overloaded cargo lifter device to check whether the goods exceeds the rated load, resulting in overheating of the pump station, overloading will seriously affect the life.
