密封

With the continuous drive of the screw, the liquid will press from a seal cavity to another cavity in a spiral manner until it is pressed out of the pump body finally.

随着螺杆的连续传动，液体以螺旋形方式从一个密封腔压向另一个密封腔，最后挤出泵体。

Check the seal filling for proper seal condition.If too loose,press down the filling cover properly.Renew the filling after operating for the month.

检查密封填料的密封情况，如太松，应适当压紧填料压盖，每运行一个月，应将旧填料取出换上新填料。

The emergency seal oil pump is running together with the main seal oil pump. What shall we do?

紧急密封油泵和主密封油泵都在运行，现在我们该怎样办呢？

The mechanical seal is below the high liquid level ensuring improved ventialtion, avoiding vapour lock and longer seal life.

机械密封是下面的高液位，确保改善ventialtion ，避免蒸气锁和较长的密封寿命。

Hydraulic cylinder piston seal for the L-cups, the Plug Valves sealing performance and durability.

液压缸的活塞密封件为L型皮碗，其密封性能好，经久耐用。

Sliding Seal: pneumatic piston-type cylinder following the sealing implementing agency for the rotary valve is designed conditions.

滑动密封：气动活塞式执行机构气缸下面的密封，为旋转式阀门工况而设计。

Ring is the most frequently used seal in hydraulic cylinder. It's typical lip seal, which is able to gain good seal effect no matter in piston or piston rod.

型圈是液压缸中最常用的油封，它是一种典型的唇口密封件，无论用于活塞还是活塞杆都能获得良好的密封效果。

Beginning with forming mechanics of seal medium, the character of magnetic fluid has been researched and magnetic fluid, which fits the demand, is made out. Then from the point of fluid mechanics, the kinematics equation and Bernoulii equation of magnetic fluid are derived. Based on the production practic of sinterer, straight seal theory is given. Last of all, the accuracy of deriving of theory is proved by experiment.

作者首先从密封介质的形成机理入手，分析了磁性流体的性质，配制出符合要求的磁性流体，又从流体力学的角度推导出磁性流体的运动学方程和磁性流体的贝努力方程，根据烧结机生产的实际，进一步推导出应用于烧结机上的直线密封理论，最后通过试验验证了理论推导的正确性。

A deep sea high pressure valve with pressure balanced poppet was designed to resolve the problem of bidirectional seal in the deep sea sampling devices.

为了解决深海取样中双向密封的困难，设计了带平衡阀芯的深海高压阀，高压阀选用耐高温、耐腐蚀、高强度工程塑料PEEK加工整体阀芯，采用PEEK阀芯-钛合金阀套的密封方式，并对这种阀的使用寿命进行了分析。

Screw pump the working principle is: screw pump work, the liquid after being inhaled into the screw pump shell and sealed by Wai space, when the initiative screw rotation, the screw pump seal volume in the squeezed increase Luoya Screw pump pressure, and along the axial movement.

螺杆泵的工作原理是：螺杆泵工作时，液体被吸入后就进入螺纹与泵壳所围的密封空间，当主动螺杆旋转时，螺杆泵密封容积在螺牙的挤压下提高螺杆泵压力，并沿轴向移动。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
