离心泵汽蚀问题的解决 |
| ①改进泵入口的结构参数 ① to improve the structural parameters of Pump Inlet 这一方案适于在离心泵的设计制造阶段，该方法在生产现场很少采用。 This program suited for centrifugal pump design and manufacture phase, the method rarely used in the production of the site. ②在泵的吸入口加装诱导轮 ② In the pump suction-induced wheel retrofit 加装诱导轮，对提高离心泵的抗汽蚀性能，解决汽蚀问题，效果很显著。而且其结构简单易于制造安装，运行维修方便，造价低，在不影响生产的前提下即可进行安装调试，特别适于在生产现场推广应用。 Installation of inducer, enhancing the anti-cavitation performance of centrifugal pumps to solve the problem cavitation, the effect is very significant. That its structure is simple and easy to manufacture and installation, operation maintenance of convenient, low cost, without affecting the production can be carried out under the premise of installation, particularly suitable for use in the production of on-site promotion. ③合理设计吸入管路及调整安装高度 ③ rational design of suction pipe and adjust the mounting height 该方法虽能消除汽蚀问题，但在生产现场却很少采用。这是因为调整泵的吸入管路及安装高度，工程量大、施工费用高，并且受施工环境的制约，只有在装置停车或大检修时才能进行；同时，由于工艺条件的限制，调整泵的吸入管路及安装高度又将影响后续工艺，具有连锁反应。 Although this method can completely eliminate cavitation problems, but the site is seldom used in the production. This is because the adjustment of the pump suction pipe and installation height, work volume, high cost of construction, and by the construction of environmental constraints, and only in the device when the parking or large maintenance be carried out; the same time, due to process conditions, the adjustment of the pump suction pipe and install a high degree of turn affect the follow-up process, with a knock-on effect. ④优化工艺操作条件 ④ optimum process operating conditions 在工艺条件允许的情况下，改变泵的流量、扬程、转速及介质的操作温度等操作参数，可以避免汽蚀的发生。但由于工艺条件的限制，优化工艺操作条件具有很大的局限性，大部分情况下效果并不显著。所以，可将该方法作为解决汽蚀问题的辅助方法。 In the process conditions permit, the change in pump flow, head, speed and medium operating temperature operating parameters, to avoid the occurrence of cavitation. However, process conditions, optimization of process operating conditions have significant limitations, in most cases results were not significant. Therefore, this method could be to solve the cavitation problem supporting facilities. 在不影响正常生产的前提下，解决机泵的汽蚀问题，应在其入口加装诱导轮。 Without affecting the normal production of the premise, the resolution of pump cavitation, it should be first choice at the entrance to the installation of inducer. |
