泥浆泵工作的可靠性取决于液力端密封结构的工作状况,在很大程度上取决于凡尔的工作性能。现场调查表明,泥浆泵凡尔在各种不同使用条件下的平均工作寿命为20～150小时。凡尔寿命短,主要是由于其结构不完善,选用材质不当,以及凡尔体和凡尔座工作面的热处理工艺(表面高频淬火)不能保持稳定的硬度等造成的。近年来研制的一种KCK型凡 The reliability of the mud pump operation depends on the working condition of the fluid-tight seal structure and largely on the performance of Versailles. Field surveys show that the average working life of the slurry pump Versail under various conditions of use is 20 to 150 hours. Versailles life is short, mainly due to its structural imperfections, improper selection of materials, and Vernal and Versailles face heat treatment process (surface induction hardening) can not maintain a stable hardness caused. In recent years developed a KCK Van
