升降舞臺(tái)變頻器如何檢查？

升降舞臺(tái)http://www.8kvv.com/變頻器定期保養(yǎng)檢查時(shí)，一定要切斷電源，待監(jiān)視器無(wú)顯示及主電路電源指示燈熄滅后，才能進(jìn)行檢查。下面南寧榮凱升降機(jī)械的有關(guān)技術(shù)人員就給大家分析一下升降舞臺(tái)變頻器如何檢查？

1、檢查升降舞臺(tái)散熱片是否有灰塵、異物堵塞風(fēng)道，壓力的干燥壓縮空氣吹掉。
Check the landing stage heatsink for dust, duct blockage, dry compressed air to blow off stress.

2、檢查升降舞臺(tái)印刷電路板是否有油污、導(dǎo)體屑附著，銅箔是否有腐蝕現(xiàn)象，可用毛刷清潔板件表面異物。
Check the landing stage PCB whether there is oil, conductor crumbs attached, if there is corrosion of copper foil, brush can be used to clean the surface of the foreign body panels.

3、檢查升降舞臺(tái)冷卻風(fēng)扇運(yùn)轉(zhuǎn)是否正常，是否有異常聲音、振動(dòng)異常，累計(jì)運(yùn)行時(shí)間達(dá)萬(wàn)小時(shí)以上，則需要更換冷卻風(fēng)扇。
Check the landing stage of the cooling fan is functioning properly, if there is abnormal sound, vibration, unusual, total running time of more than ten thousand hours, you need to replace the cooling fan.

4、檢查升降舞臺(tái)功率元件是否有灰塵、油污等異物附著，必須清潔處理異物。
Check that the landing stage power components dust, oil and other foreign objects attached, must be cleaned of foreign material.

5、檢查升降舞臺(tái)http://www.8kvv.com/電解電容是否有漏液、鼓泡現(xiàn)象，防爆閥有無(wú)突起，需要進(jìn)行更換電解電容。
Check the landing stage electrolytic capacitor leaks, bubbling phenomenon, explosion or without protruding valve needs to be replaced electrolytic capacitors.
