Pump circulates by the tower that the GA-203 pump that Qilushi changes workshop of joint-stock company splitting decomposition is DA-203 tower, it enrages classics splitting decomposition alkaline washed chroma still taller lye carries cat head recycle to use. This pump is driving earlier moving state is better, but often produce leak after moving period of time, maintenance frequency rises, raised upkeep costs and product cost, the long-term stability that affected unit moves. (1) invalidation analyses general and mechanical sealed invalidation to basically have 4 kinds of forms, corrode namely, the hot caustic, invalidation that wears away to be caused with the element such as installation, movement. The sealing surface after this pump disintegrate is mixed without nick wear away, because this can exclude the account of respect of injury of sealing surface physics. Consider content of the crystallization inside annular seal space and rubiginous skin are more, link a lot of performance of mechanical and sealed invalidation at the same time, preliminary decide the easy crystallization sex that carries medium and caustic it is the main reason that causes sealed invalidation. (2) improve measure A.

Change stretch component structure: Will stretch component is in charge of by bedspring instead ripple, component of flexibility of moire canal since is the auxiliary sealing ring that moves link, leave out uses the O of annulus and axial apartment group formerly, simply is moving link the stock that end place adds one gaskets to seal the place, settled O group already so sealed contradict with compensatory, will allow static sealed instead formerly again completely static sealed, make sealed dependability rises. Convert moire canal returns leave out the drive with bedspring sealed machinery is sold and move annulus and move link between coordinate a side, the action moving link that avoided to be caused by the deposit of solid grain content is out of order, rose further machine sealed integral function. Moire canal offers stretch compensation to offer torque again already, have better tracing ability and compensation capacity. B.

Static annulus compensation replaces the compensation that move link: Be in machine the quality that annulus part uses in sealing package is far bigger than static annulus part, reason movement rises amount of roll coming back is large also. Instead reduced roll coming back to measure after static annulus compensation, raised whole machine to seal the stability of package and dependability. C.

Increase use annulus and axle sleeve space: Increase this clearance to be able to avoid the deposit of crystallization content and rubiginous skin, the internal diameter that move link increases below the premise that makes sure end panel comparing is pressed or reduce axle sleeve internal diameter all but. Recommend according to concerning a material, clearance by 0 original.

38mm is added to 0.

5mm. D.

Increase aperture of strong Xian line appropriately: Be aimed at the actual condition with crystallization content and rubiginous more skin, raise the deposit that rinses a quantity to settle solid grain matter effectively, reason beard will rinse line aperture formerly by 12.

7mm is added to 19.

05mm. But should notice, cross the earth to increase bore diameter to be able to reduce the efficiency of pump. E.

Increase entrance filter mesh to count: Increase mesh to look number can prevent solid grain content effectively to enter annular seal space, for machinery sealed provide relatively perfect work environment. CNC Milling
