Xu Xinhua rubber seals rotary dynamic seal leakage to exclude

(1) rubber seals leak too much. Causes and measures:

1, the assembly bad: Correct installation of rubber seals, do not reversed or misplaced

2, the lip pressure is insufficient (Seal): Seal check the correct size or not, spring is working

3, the shaft rough spots or scars: lower roughness of the shaft, or use soft seal or other sealing materials

4, the sealing lip cracking: It may be caused due to the rough surface of the shaft, the sealing material is incorrect or speed, temperature is too high and other reasons

5, the rubber seal is damaged or worn: replace the seals and the seal is to improve the wear resistance

(2) large rubber seal friction. Causes and measures:

1, poor lubrication: Xu may switch from the friction surface of polytetrafluoroethylene

2, pre-load is too large: may promise change seal type

3, the pressure is too large: may promise change seal type

(3) rubber ring seal is broken. Causes and measures:

1, improper installation or carelessness: the use of appropriate technologies and tools

2, the shaft rough: See the technical requirements of surface roughness and chamfer

3, there is the presence of abrasive particles (also reflected shaft wear), equipped with a dust seal in dusty environments

(4) rubber ring seal excessive wear. Causes and measures:

1, seal type or material selection errors: equipped with more suitable type of seal according to the working conditions

2, the pressure is too high: more suitable type equipped with a seal according to the working conditions

3, the temperature is too high: more suitable type equipped with a seal according to the working conditions

3, reciprocating seals leak exclusion

(1) a large rubber ring friction. Causes and measures:

1, rubber seal assembly bad: according to the recommended standard checking the seal, if necessary, reduce the amount of interference or pressure

2, improper size rubber ring seal: checking Dimensions

3, rubber seals the surface roughness is too large: reduce the surface roughness or use in rough surface friction sealing material

4, the friction velocity big: may need to change the seal type

5, sealing medium work pressure: you may need to change the type of seal or seal material

(2) crawling, causes and measures:

1, the seal dry friction: improving working conditions

2, the surface roughness is too large: reduce the surface roughness or use in rough surface friction sealing material

3, the lubricant film formation of undesirable: to improve working conditions or change the seal type (such as using a combination of PTFE seal

(3) rubber seals leak too much. Causes and measures:

1, install anti seal: checking, two-way seal or necessary

2, preload inadequate: checking the size and preload

3, shrink seals: Check the sealing material is compatible with the sealing medium

4, seal wear: replace the seals, check the wear reason, if the low life Consider replacing seal type

(4) rubber ring seal is broken. Causes and measures:

1, rubber seals initial improper assembly: Replace the seals as required, and carefully check the installation status

2, failure to reverse the rubber seals (O-ring): check the O-ring geometry and applicability

3, the gap bites: reduce extrusion gap provided when necessary is to add laps

4, wear: check size, if necessary, adjust the extrusion gap

4, rubber ring seal storage
