使润滑

Mist is a compressed air-driven device, the lubricant spray into a mist, and mixed in the compressed air so that the compressed air has the ability to lubricate pneumatic components.

油雾器是以压缩空气为动力，将润滑油喷射成雾状，并混合于压缩空气中，使该压缩空气具有润滑气动元件的能力。

The rotor, supported by babbitt metal made bearing, suspends on the bearing pad thanks to oilfilm lubrication by the fuel feeding system. The end clearances can be adjusted automatically to make oilfilm on both ends the same thickness and ensure no leakage. Compared with screw compressors whose output ends would clasp, this compressor has no possibility of the bearing and rotor biting together.

采用航空级的巴氏合金轴承支撑的转子，通过供油系统提供的油膜润滑：转子能悬浮与轴瓦上，并自动调节端面间隙，使两端油膜厚度相并无泄露，该轴承能保证转子轴绝无咬死之可能，而螺杆压缩机因受轴向力的作用排气端间隙，容易有咬死，抱紧现象。

Another some of characteristic of this equipment is: Go up automatically line, self-adjusting control a foot, automatic reinforced stitches reachs backstitch; The change spending type of all sorts of stitch amounts to 80 ～ 190 kinds; The automatic lubricant system protecting clean of initiate, oiliness bearing, durable and safe clutch, make this equipment needs what lowest is restricted to maintain only.

此设备的另一些特点是：自动上线，自动调节压脚，自动回针及倒缝；各种针法的花式变化达80～190种；首创的自动润滑保洁系统，含油轴承，耐用安全离合器等，使该设备只需最低限的保养。。。

It was found that with the increase in the oscillating frequency for a fixed oscillating angle, the film thickness increases, which may contribute to the formation of the oil film; however, the maximum pressure and the pressure scope during an oscillation cycle also increase; which may shorten the fatigue life of the bounding surface in the latter situation.

结果表明：在摆程不变的条件下，膜厚随摆动频率增加而增大，有利于润滑膜的建立，但同时会增加1个周期中的最大压力及压力波动幅度，使工件易于疲劳；对于相同凸度量，在低频摆动工况下边缘效应较高频工况下的严重，因此在低频摆动工况下使用滚子设计时需要增大其凸度量。

The cylinder of drop forging hammer was improved with oilless lubrication technique.

运用气缸无油润滑技术对模锻锤进行技术改造，使气缸和活塞的使用寿命延长，大大降低了设备的维修费用，也改善了机器的使用性能。

Lubrication of the metal catheter before it is inserted into the eyehole makes both insertion and removal of the metal catheter easier.

润滑的金属导管，然后才能插入眼窝都使插入和删除的金属导管容易。

The fire-brigade was called and two firemen freed George using a special type of grease .

有人打电话叫来消防队，两位消防队员使用了一种特殊的润滑调剂才使乔治得以解脱。

In fact, there is little pump of the fluid loss, which makes the operation of pumps can not achieve 100% efficiency, as these fluids are used to on both sides of bearing and gear lubrication, and the pump body is also not possible with no gap, it can not be so that 100% of fluid discharged from the export, so a small amount of fluid loss is inevitable.

实际上，在泵内有很少量的流体损失，这使泵的运行效率不能达到100％，因为这些流体被用来润滑轴承及齿轮两侧，而泵体也绝不可能无间隙配合，故不能使流体100％地从出口排出，所以少量的流体损失是必然的。

The tribological properties of 500 SN oil containing nanometer copper borate were investigated with a four ball machine and a block on ring friction and wear tester.

结果表明：纳米硼酸铜使500SN基础油润滑下的摩擦系数略有增大，并使其抗磨及承载能力提高；其最佳添加量为0.70%～1.10%；纳米硼酸铜颗粒在摩擦表面发生了摩擦化学反应，生成了由B2O 3及FeB等组成的表面保护膜。

In the course of choosing materials, the electric motors of AAA electric fans adopt high-intensity double-layer insulation polyester enamel-insulated wires, and Pumaweike lubricating grease, to enable the motors to have a longer lifespan; they utilize self-oiling bearings, to make the motors quieter, and have a longer durability; ultra-temperature protection and control devices are also used to give a greater safety factor.

在材料选择中，AAA电风扇电机采用高强度双层绝缘聚脂漆包线，采用普玛威克润滑油脂，使电机使用寿命更长，采用含油铜轴承，使电机噪音小，耐磨时间更长，使用超温保护控制装置，安全性能更强。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
