Water flow prevents bubble explosion, reduces noise, promotes expansion tank reliability and system radiating performance, while evading cavitation erosion risk.
Least risk: source control initially fills coolant liquid, enters back into after first passing around expansion tank core tertiary treatment
Engine operation, for engine input cleaning coolant liquid, problem is controlled from source, by cooling system work in risk control
System is in minimum zone.
Cost is reduced, user satisfaction is promoted: need to only spend very low expense to regularly replace expansion tank, and not have to spend big valence
Money cleans water channel, is also not thorough.User is greatly reduced with vehicle cost, effect is more preferable.
The expansion tank of the technical program passes through level-one Physical Absorption, isolation and second level, three-level by built-in core
Effect, the iron rust generated in absorption cooling system work, scale, bubble and reaction treatment calcium ions and magnesium ions, iron ion, it is acid from
The potential threats such as son make coolant liquid pH value maintain suitable constant range, clean for system output, the coolant liquid of safety, with
Guarantee the safe and efficient lasting work of cooling system.

Resin layer is necessary for twice of cation exchange resin layer volume.
When cooling system pressure reaches setup pressure value, relief valve and pressure cover in venting conduit can be opened successively,
As shown in fig. 6, expansion tank completes exhaust pressure relief work, after cooling system pressure reduction, relief valve and pressure cover can be closed successively
It closes.
Built-in core working principle:
Level-one effect absorbs iron rust, scale and separation bubble by M type high molecular composite filtering paper layer 24.
Second level effect, acid ion etc. is disposed by anion exchange resin layer 25 and endangers ion, and generate hydrogen-oxygen from
Son.
Three-level effect, disposes calcium ion, magnesium ion, iron ion etc. by cation exchange resin layer 26 and endangers ion simultaneously
Generate hydrogen ion.
When cooling system works, coolant liquid is vented water pipe head, engine exhaust water pipe head into the by radiator
After one cavity area, first passes around M type high molecular composite filtering paper layer and complete iron rust, scale absorption and bubble isolation (prevention bubble
Cooling water circulation is participated in, heat dissipation performance is improved), using anion exchange resin layer, ion-exchange treatment falls acid ion, most
Afterwards by cation exchange resin layer, fallen by ion exchange the calcium ion in coolant liquid, magnesium ion, iron ion etc. endanger from
Son.
After coolant liquid is by the above tertiary treatment, hazardous substance is all disposed, second level effect and three-level effect
Hydroxyl ion and the hydrogen ion chemical reaction generated afterwards generates the deionized water harmless to cooling system, it is ensured that cooling system can pacify
Full persistent high efficiency operation.
