What are the water pump wearing parts?

1. Wearing parts are the most vulnerable part of the pump. In the process of using, repairing and maintaining, special care is needed for wearing parts.What should I pay attention to?Water pump agent to join small make up for you one by one:2. Water pump pump shell is usually cast iron parts, it is seen by mechanical force or the effect of thermal stress crack when the pump at work due to the impact of the cavitation effect or in winter without draining water accumulation in the pump shell is also easy to broken when frozen, such as damage is not repair should be change to new pump casing 3. Pumps pump shaft of the carbon steel is commonly, but due to reasons such as manufacturing quality use or installation is easy to damage the pump shaft bending crack shaft neck wear may occur thread failure and so on, also may appear fracture accidents such as badly damaged beyond repair, should replace the new shaft4. Impeller is an important working part of water pump. It is made of cast iron.Some defects can not be repair, that is, a new impeller should be replaced 5. Sliding bearing bush is copper's tin alloy cast, poor wear resistance, is one of the most easy to wear and burn out of wearing parts, bearing shell can repair commonly, also can replace a new general average service life of rolling bearings for 5000 hours, but improper installation, use a long time or poor maintenance, and easy to wear or destruction of rolling bearing, besides the individual parts can change the new general is to replace the whole piece of 6. Reduce mouth ring, also known as the leakage or wearing ring, it is one of the most easy to wear and tear parts in pumpsSteady flow can wear after could repair can also change the new when new minus leakage ring, the inner diameter should be configured according to the impeller inlet diameter wear, such as impeller inlet diameter can be turning processing, in order to eliminate the trench and ellipse, and then configure miniature minus leakage ring inside diameter of the impeller inlet diameter can generally be turning 7. Three times after packing with long will harden and lose elasticity, makes the pump leak leakage, general new packing should be replaced

水泵易损件有哪些?
1.易损件是水泵最脆弱的地方，在使用、维修和保养等过程中，需要对易损件进行特别照顾。那么一台泵，他的易损件有哪些?要注意些什么?水泵代理加盟小编为您一一道来：

2.水泵泵壳一般都是铸铁件，它受机械力或热应力的作用易出现裂纹。当水泵在工作中因受汽蚀作用的冲击或在冬季没有放掉泵壳内积水而受冰冻时也易破裂，如损坏较重不能修理时应更换新泵壳。

3.水泵泵轴一般为碳钢件，但由于制造质量、使用或安装等原因也易损坏。泵轴可能出现裂纹、弯曲、轴颈磨损、螺纹损坏等，也可能出现断裂事故。如损坏严重不能修理时，应更换新轴。

4.叶轮是水泵的重要工作部件，为铸铁制成。由于制造质量和使用等原因也易损坏。叶轮可能会出现裂纹，因汽蚀作用表面形成窝眼或穿孔，长期被冲磨使叶片变薄或偏磨，甚至被杂物击碎。有些缺陷可以修复;有些缺陷不能修复，即应更换新叶轮。

5.滑动轴承的轴瓦是铜氏锡合金铸成的，耐磨性很差，是最易磨损和烧坏的易损件之一，轴瓦一般都可以修复，也可更换新件。滚动轴承一般平均使用寿命为5000小时，但安装不当，使用时间长或保养不良，也易磨损或毁坏。滚动轴承除其中的个别零件可以调换新的外，一般均要更换整体件。

6.口环也称减漏或减磨环，它是水泵中最容易磨损的零件之一。稳流罐磨损后可以修理也可以更换新的。当更换新减漏环时，其内径应按叶轮入口外径来配置。如叶轮进水口外径磨损，可进行车削加工，以消除沟痕和椭圆，然后再配置内径缩小的减漏环，叶轮进水口外径一般可车削三次。

7.填料用久后会变硬而失去弹性，会使水泵漏气、漏水，一般应更换新填料。
