柴油机热油泵※13775024666常州市武研热油泵有限公司※柴油机热油泵机械密封失效的原因:4.安装、运转等引起的故障分析:(1)加水或静压试验时发生泄漏。由于安装不良,机械密封加水或静压试验时会发生泄漏。如果用手转动轴泄漏方向性会方向有如下原因:弹簧力不均匀,单弹簧不垂直,多个弹簧长短不一或个数少;密封腔端面与轴垂直不够。静环压紧不均匀。(2)由安装、运转等引起的周期性泄漏。运转中如果柴油机热油泵泵叶轮轴向窜动量超过标准、转轴发生周期性振动以及没有稳定的操作工艺,密封腔里的压力经常变化都会导致密封周期性泄漏。Hot oil pump mechanical seal failure reasons: 4. Installation, operation caused by fault analysis: (1) adding water.hydrostatic test occurred leakage due to improper installation, mechanical seal.hydrostatic test of water will leak. With the hand rotating shaft leakage direction of, for the following reasons: spring force is not uniform, single spring is not vertical, multi spring of different lengths.fewer in number; sealing cavity surface.the vertical axis is not enough. Static ring pressed unevenly. (2) caused by the installation, operation cycle of leakage in operation such as pump impeller axial runout exceeds the standard, a rotating shaft occurred periodic vibration.the process is not stable, sealed cavity pressure is constantly changing will lead to cyclical seal leakage.
