机械密封优点
1、密封可靠在长周期的运行中，密封状态很稳定，泄漏量很小，按粗略统计，其泄漏量一般仅为软填料密封的1/100；
2、使用寿命长在油、水类介质中一般可达1～2年或更长时间，在化工介质中通常也能达半年以上；
3、摩擦功率消耗小机械密封的摩擦功率仅为软填料密封的10%～50%；
4、轴或轴套基本上不受磨损；
5、维修周期长端面磨损后可自动补偿，一般情况下，毋需经常性的维修；
6、抗振性好 对旋转轴的振动、偏摆以及轴对密封腔的偏斜不敏感；
7、适用范围广机械密封能用于低温、高温、真空、高压、不同转速，以及各种腐蚀性介质和含磨粒介质等的密封。
8、对许多工厂的“零泄漏”需要，填料密封无法达到此要求；根本适应范围广，随意性更大，但对于在工厂，经常更换或维护将对工厂造成很大损失。

我们的螺杆泵产品在出厂之前已经按规定做了详细的检查和测试，由于是新泵的原因，泵内会有我们测试后残余的油，这都是正常的情况，
我们的螺杆泵都是按国标生产的，客户不管是买备件还是整机都可以和现场使用的泵替换，对于非标的螺杆泵产品，我们会提醒客户进行
比对，核实无误后才会生产，然后交付客户使用，避免客户买到泵之后会出现的和现场使用的泵不一样情况的发生，减少了客户的损失。
