大慣量（寬調速）直流伺服電動機雖然具有上述特點，但是，對它進行控制不如步進電機簡單，快速響應性能也不如小摜量電動機，寬調速直流伺服電動機轉子由于采用良好的絕緣，耐溫可達150～200℃。轉子溫度高，熱量通過轉軸傳到絲桿，絲杠的變形將影響傳動精度，因此，出現(xiàn)了熱管形的大慣量電機，即將電機軸做成空心，在軸內裝氟里昂之類的工作介質，介質在管內反復蒸發(fā)和冷卻，將熱量由高溫區(qū)傳至低溫區(qū)，終散發(fā)到周圍環(huán)境中去。
伺服電機被步進脈沖控制的優(yōu)點:
(1)可靠性高，不易發(fā)生飛車事故。用模擬電壓方式控制伺服電機時，如果出現(xiàn)接線接錯或使用中元件損壞等問題時，有可能使控制電壓升至正的值。這種情況是很危險的。如果用脈沖作為控制信號就不會出現(xiàn)這種問題。
(2)信號抗干擾性能好。數(shù)字電路抗干擾性能是模擬電路難以比擬的。

旋振篩篩網(wǎng)應安裝在篩網(wǎng)架上，安裝或拆卸篩網(wǎng)應先拆下篩圈（框），出料口朝上放置在平臺上后放下篩網(wǎng)架，篩網(wǎng)平鋪在篩網(wǎng)架上，然后放上篩網(wǎng)壓緊圈，按照篩網(wǎng)的垂直方向用螺釘對稱稍作固定，在確定篩網(wǎng)無縐折、松緊均勻、篩孔正方形狀后分別將螺釘穿入螺孔中，慢慢逐個均勻輪換擰緊，后裁去多余的篩網(wǎng)即可。.因為篩網(wǎng)架和篩網(wǎng)壓緊圈采用燕尾槽結構設計，所以越壓篩網(wǎng)繃的越緊，確保篩網(wǎng)繃緊；如客戶無特殊需求，篩網(wǎng)架通常采用鋁合金材料，篩網(wǎng)架壓緊圈和篩網(wǎng)架的間隙有一定的范圍，如遇特粗篩網(wǎng)時應增加這個間隙，如未到位，則用木榔頭輕輕、均勻敲擊，或使用臺鉗邊緊邊擰螺釘，這個過程應特別小心，以免導致篩網(wǎng)架壓緊圈認為斷裂。

安裝注意事項
1.滾動軸承的安裝滾動軸承安裝時軸承內圈應緊貼軸肩，要求縫隙不得通過0.05mm厚的塞尺。
2.軸承軸向游隙對游隙不可調整的軸承（如深溝球軸承），其軸向游隙為0.25~0.4mm；對游隙可調整的軸承軸向游隙數(shù)值見表。點擊查看圓錐滾子軸承軸向游隙；角接觸球軸承軸向游隙
3.齒輪（蝸輪）嚙合的齒側間隙可用塞尺或壓鉛法。即將鉛絲放在齒槽上，然后轉動齒輪而壓扁鉛絲，測量兩齒側被壓扁鉛絲厚度之和即為齒側的大小。
4.齒面接觸斑點圓柱齒輪齒面接觸斑點。

為此，現(xiàn)在上又開發(fā)金屬密封蝶閥，氣蝕區(qū)減小，近幾年我國也開發(fā)了金屬密封蝶閥，在日本近年來還開發(fā)耐氣蝕、低振動、低噪聲的梳齒形蝶閥。一般密封座的壽命在正常情況下，橡膠15年-2年，金屬的8年-9年。但如何正確選用則要根據(jù)工況要求。蝶閥的使用：蝶閥的開度與流量之間的關系，基本上呈線性比例變化。如果用于控制流量，其流量特性與配管的流阻也有密切關系，如兩條管道安裝閥門口徑、形式等全相同，而管道損失系數(shù)不同，閥門的流量差別也會很大。
