大惯量（宽调速）直流伺服电动机虽然具有上述特点，但是，对它进行控制不如步进电机简单，快速响应性能也不如小掼量电动机，宽调速直流伺服电动机转子由于采用良好的绝缘，耐温可达150～200℃。转子温度高，热量通过转轴传到丝杆，丝杠的变形将影响传动精度，因此，出现了热管形的大惯量电机，即将电机轴做成空心，在轴内装氟里昂之类的工作介质，介质在管内反复蒸发和冷却，将热量由高温区传至低温区，终散发到周围环境中去。
伺服电机被步进脉冲控制的优点:
(1)可靠性高，不易发生飞车事故。用模拟电压方式控制伺服电机时，如果出现接线接错或使用中元件损坏等问题时，有可能使控制电压升至正的值。这种情况是很危险的。如果用脉冲作为控制信号就不会出现这种问题。
(2)信号抗干扰性能好。数字电路抗干扰性能是模拟电路难以比拟的。

旋振筛筛网应安装在筛网架上，安装或拆卸筛网应先拆下筛圈（框），出料口朝上放置在平台上后放下筛网架，筛网平铺在筛网架上，然后放上筛网压紧圈，按照筛网的垂直方向用螺钉对称稍作固定，在确定筛网无绉折、松紧均匀、筛孔正方形状后分别将螺钉穿入螺孔中，慢慢逐个均匀轮换拧紧，后裁去多余的筛网即可。.因为筛网架和筛网压紧圈采用燕尾槽结构设计，所以越压筛网绷的越紧，确保筛网绷紧；如客户无特殊需求，筛网架通常采用铝合金材料，筛网架压紧圈和筛网架的间隙有一定的范围，如遇特粗筛网时应增加这个间隙，如未到位，则用木榔头轻轻、均匀敲击，或使用台钳边紧边拧螺钉，这个过程应特别小心，以免导致筛网架压紧圈认为断裂。

安装注意事项
1.滚动轴承的安装滚动轴承安装时轴承内圈应紧贴轴肩，要求缝隙不得通过0.05mm厚的塞尺。
2.轴承轴向游隙对游隙不可调整的轴承（如深沟球轴承），其轴向游隙为0.25~0.4mm；对游隙可调整的轴承轴向游隙数值见表。点击查看圆锥滚子轴承轴向游隙；角接触球轴承轴向游隙
3.齿轮（蜗轮）啮合的齿侧间隙可用塞尺或压铅法。即将铅丝放在齿槽上，然后转动齿轮而压扁铅丝，测量两齿侧被压扁铅丝厚度之和即为齿侧的大小。
4.齿面接触斑点圆柱齿轮齿面接触斑点。

为此，现在上又开发金属密封蝶阀，气蚀区减小，近几年我国也开发了金属密封蝶阀，在日本近年来还开发耐气蚀、低振动、低噪声的梳齿形蝶阀。一般密封座的寿命在正常情况下，橡胶15年-2年，金属的8年-9年。但如何正确选用则要根据工况要求。蝶阀的使用：蝶阀的开度与流量之间的关系，基本上呈线性比例变化。如果用于控制流量，其流量特性与配管的流阻也有密切关系，如两条管道安装阀门口径、形式等全相同，而管道损失系数不同，阀门的流量差别也会很大。
