font-size: 14px; line-height: 2;"><strong>螺杆真真空泵</strong>是把两个经过严格动平衡校正、用轴承做支撑的螺杆，安装在泵腔内，并在两个螺杆之间留下合理的空隙。此设备在运转的时候，两个转子在泵腔内作同步高速反向旋转，由此来产生吸气和排气。因为转子经过严格的动平衡校正，并且两个轮子间也留下了合理的间隙，因此泵工作时，转子不会相磨擦，运转平稳，噪音低，并且工作腔内不需润滑油，消耗功率低，螺杆真空泵具有节能，免维修等优点，特别适用于要环境及噪音要求比较高的环境、�/span><br style="color: rgb(51, 51, 51);

font-size: 14px; line-height: 2;">1、气压力会对螺杆真空泵吸气量和轴运转功耗带来巨大的影响。系统在运行时，若排气压力越大时，其吸气量越小，轴运转功耗就会越大。当系统排气压力越小时，吸气量就会越大，相应轴运转功耗就会越小、�/span><br style="color: rgb(51, 51, 51); font-family: 微软雅黑, Arial, Helvetica, sans-serif;
