查询词典 pump

The influence of the eccentricity mass moment, position of mass center and the bearing stiffness to the vibration characteristics of the rotor system is discussed in detail; 3. To verify the exactness of FEM and learn the principle of vibration of dredge pump further, The orbit of the rotor shaft of the pump in the dredger is measured, the measurement results show: the repeat of the orbit of the rotor shaft is very bad when dredge pump is in the dredging mud condition.

模态分析确定了泥泵的振动特性；谐响应分析确定了泥泵转子轴在偏心力的作用下轴截面处的最大响应位移；研究了转子轴的质心位置、轴承刚度和质量偏心矩对转子轴振动特性的影响； 3、采用轴心轨迹法，实船测量了泥泵轴工作时振动响应值。

引射泵或射流泵的发动机可能是在泵上悬挂的一个独立单元，或者发动机的端盖是泵的一部分。

In case that vacuum pump stops working or power supply is suddenly broken off, valve will be cosed automatically to keep the vacuum system vacuum and the air charged into the cavity of vacuum pump, thus to prevent pump oil from reverse flow that can pollute the vacuum system.

使真空系统保持真空并将大气充入泵腔内，从而避免泵油逆向流动而污染真空系统。

With the technology, improve manufacturing processes and quality materials to choose from, small-scale rotor vane vacuum pump can be directly linked with the motor shaft, speed can be as high as 1450 r / min, significantly increased the pump rate and reduced exhaust pump.

随着技术的发展、制造工艺的完善和优质材料的选用，小型滑片真空泵的转轴可与电动机轴直联，转速可高达1450转／分，大大提高了泵的抽气速率和减轻了泵的重量。

As the molecular pump pumping speed for water vapor is only with the diameter cryopump pumping speed of the quarter, so molecular pump exhaust pump longer time than low temperature.

由于分子泵对水蒸气的抽速仅为同口径低温泵抽速的四分之一，所以分子泵的排气时间比低温泵长。

If you do see a white colored smoke near the pump exhaust, this could possibly be oil mist from the pump and have nothing to do with the plasma cleaner itself; this could be corrected with a suitable oil mist filter for the pump in question.

如果看见真空泵排气口处有白色烟气，这可能是从泵里面排除的油雾，与等离子清洗机本身没任何关系；这个问题可以通过更换适当的油雾过滤器来解决。

Rated at extraction conditions, one pump is running, because the cycle of water to reduce the system's water resistance decrease the flow of water pumps 12274T / H, head will drop to 15.0-16.0 m, in the extraction steam turbine at the maximum operating conditions, the recycled water to meet the system requirements to run a pump, because of substantial reduction in the volume of water supplied, so that substantially improve pump head, a direct result of the cooling tower water gushing, increase淋水device with a flow rate of the sink, fill up water in the hot淋水exchange reduce the time and reduces the cooling effect of cooling towers.

在额定抽汽工况下，一台水泵运行，由于循环水量减少、系统的水阻下降，水泵的流量12274T/H，扬程将下降至15.0-16.0米，在汽轮机在最大抽汽工况时，为满足循环水系统要求运行一台水泵，由于供水量大幅度减少，使水泵扬程大幅度提高，直接造成冷却塔涌水，加大淋水装置配水槽的流速，水流在淋水填料上热交换的时间减少，降低了冷却塔的冷却效果。

High-temperature liquid transfer pump, such as power plant boiler feed pump, before you start heating pump.

输送高温液体的泵，如电厂的锅炉给水泵，在启动前必须先暖泵。

It has important real signification to study the condition forecasting of feed water pump, advance the safety and reliability of operation of feed water pump and to develop condition maintenance to feed water pump.

开展给水泵状态预测的研究，提高给水泵运行的安全性、可靠性及状态维修，都具有重要的现实意义。

Boiler feed pump minimum flow valve cycle Control requirements: the boiler feed pump safe start-up and running, eliminate traffic is too small, temperature increase, the water a strong cavitation damage to the pump.

锅炉给水泵最小流量循环阀控制要求：使锅炉给水泵安全启动及运行，消除因流量过小、温升增加、水强烈气蚀使泵损坏。
