以前对于小型潜水电泵机械密封的评价,往往只注重于密封寿命。笔者通过对该类密封现状的分析及简易的试验,认为小型潜水电泵机械密封的能耗约占潜水电泵总能耗的3.5%左右,故减少机械密封的能耗,对提高小型潜水电泵的经济效益具有普遍意义。考虑这一情况,本文对进一步提高小型潜水电泵机械密封的技术经济指标的途径提出初步的探讨。
Previous small submersible pump mechanical seal evaluation, often only focus on seal life. The author through the analysis of the status quo of the seal and a simple test that the small submersible pump mechanical seal energy consumption accounts for about 3.5% of the total energy consumption of submersible pumps, it reduces the mechanical seal energy consumption, to improve the small submersible The economic benefits of pumps have universal significance. Considering this situation, this article puts forward a preliminary discussion on ways to further improve the technical and economic indexes of small submersible pump mechanical seal.
