目前市场上，除了指纹识别外，有些还有加配功能，所以这类指纹锁也常常被称为指纹锁。指纹、和应急钥匙可分别开启。功能视安全设置，长度在4-12位之间，数字键一般采用-9全数字输入方式。当然指纹锁也不是越贵越好，真正在买指纹锁的时候，一般应该关注安全性、稳定性、通用性和智能性。安全性安装指纹锁后，应当不影响用防盗门的功用。锁具不存在明显的安全隐患。稳定性是指纹锁最重要的指标，一般需一年以上的实际使用后才会慢慢稳定下来，定型。

不同类型的步进电动机在以下几个方面存在差异：

工作原理：步进电机可分为永磁式、反应式和混合式三种。永磁式步进一般为两相，转矩和体积较小，步进角一般为7.5度或15度。反应式步进一般为三相，可实现大转矩输出，步进角一般为1.5度，但噪声和振动都很大。混合式步进是指混合了永磁式和反应式的优点，分为两相四相和五相，具有更高的应用广泛性。
扭矩和体积：不同类型的步进电动机的扭矩和体积不同。一般来说，步进电机越小，其扭矩就越小，但体积也会相应减小。相反，步进电机越大，其扭矩就越大，但体积也会相应增大。
成本和维护难度：不同类型的步进电动机的成本和维护难度也有所不同。一般来说，高性能的步进电动机通常成本较高，维护难度也较大。而普通的步进电动机则相对成本较低，维护难度也较小。
精度和可靠性：不同类型的步进电动机的精度和可靠性也有所不同。一般来说，高性能的步进电动机具有更高的精度和可靠性，能够满足高精度的应用需求。而普通的步进电动机则相对精度较低，可靠性也较差。
综上所述，不同类型的步进电动机在工作原理、扭矩和体积、成本和维护难度以及精度和可靠性等方面存在差异。因此，在选择使用步进电动机时，需要根据实际应用场景和需求，综合考虑上述因素，选择合适的类型以及负载扭矩。

对静密封件的要求静密封件在刚性固定表面之间防止油液外泄。合理设计密封槽尺寸及公差，使安装后的密封件到一定挤压产生变形以便填塞配合表面的微观凹陷，并把密封件内应力提高到高于被密封的压力。当零件刚度或螺栓预紧力不够大时，配合表面将在油液压力作用下分离，造成间隙或加大由于密封表面不够平而可能从开始就存在的间隙。随着配合表面的运动，静密封就成了动密封。粗糙的配合表面将磨损密封件，变动的间隙将蚕食密封件边缘。
