1.用户更换的轴承多是在机电市场或轴承店采购的,用户采购轴承只看型号而忽视了导热 油泵的高温高速的特性,选择热 油泵轴承必须要求具备耐高温、高速的条件,否则不适用于
导热油泵。
2.轴承装配工艺有问题;厂部组装车间在装配轴承时都用专用工具,排装第一块轴承与第二块轴承使用的工具不同,目的使轴承内环与外环同时受力以保证轴承原始性能,据了解很多用户在更换轴承时忽视了轴承安装的过程,加之使用非专用工具排装,往往使轴承在安装过程中因受力不当造成人为损坏,这是至关重要的问题。
3.导热 油泵在运行2000-3000小时后必须及时添加或更换轴承体内润滑油,来保证轴承有良好的润滑性,来延长轴承使用寿命。
4.在更换轴承时,也要判断轴的磨损程度,如果碳纤维填料处磨损严重,建议连同轴一起更换,碳纤维处磨损严重会造成导热油与机油室的润滑油混合,使润滑油丧失润滑性,另外管路中的导热油有杂质也会滚入轴承内,加速轴承损坏。
5.建议在更换轴承时连同泵内密 封件一起更换,同时清洗叶轮内部的积碳以保证有足够的流量与压力。
6.泵头组装完毕后用浸水中打气压检验是否漏气,如有漏气说明在组装过程中有密 封不严之处;后泵头与电机组装务必调整好同心度,否则噪音大且对联轴 器内部胶块磨损过快。
1 heat conducting oil pump must be timely to add or replace the oil lubrication bearing in the running after 2000-3000 hours, to ensure that the bearing lubrication of a good, to extend the service life of bearing.Bearing
2 user replaceable is procurement in the electrical market or bearing shop, users buy bearings only models and ignore the heat conducting oil pump of high speed andhightemperature properties, selection of hot oil pump bearing must have high temperature resistant, high speed conditions, otherwise it is not suitable for hot oil pump.
3 bearing assembly process problem; in assembling the bearing with special tool factory assembly workshop, is arranged the first piece of bearing and the second bearing use different tools, at the same time the force to make the bearing inner ring and the outer ring to ensure the bearing the original performance, it is understood that many users in the replacement of bearingsIgnore the installation of bearings, and the use of non special tool is arranged, often make the bearing in the process of installation causedby improper artificial damage due to the stress, which is the key issue.
4 in the replacement of bearings, also want to wear to judge the degree of shaft, if carbon fiber filler wear serious, suggest even coaxial replaced together, lubricating oil mixed carbon fiber wear serious can cause the heat conduction oil and the oil chamber, the oil loss of lubrication, thermal oil and pipeline in the complexMatter will be rolled into the bearing, accelerated bearing damage.
5 proposals in the replacement of bearings with the pump seal replacement, while cleaning the carbon deposition inside the impeller flow and pressure to ensure there is enough.
6 pump head assembly after soaking in a pressure test whether the leak, if leakage in the assembly process is not seal point; finally, the pump and motor assembly must adjust good concentricity, otherwise the noise and internal rubber poetic couplet axis block wear too fast.Conclusion: oil pump which belongs to the mechanical wear of the equipment, maintenance and repair, good maintenance can make the vulnerable components to increase the service life of many, as Huangdi Neijing said: "so the sage does not treat the disease preventive treatment of disease, not cure is not chaos chaos, this is. Sickness is then medicine, chaosIs then treat them, for example still thirsty and wear well, behind time, didn't also late on"! Small investment for the big harvest, discover and solve problems in a timely manner, not to not run when the overhaul.
