What tasks does the exploration of the expansion ship has the expansion ship?

The expansion ship acts as a compensation tank: when heated, the cooling liquid visibly extends to the volume. In a very old car, there is no separate expansion tank and the radiator himself plays this role.

The radiator compass has carried out the same task as modern expansion cars, due to the presence of a steam steam valve of steam which allows water to boil only at 109-112 degrees.

In addition, an air valve was supplied in the radiator cap, usually in the void (0.01 -0.0.10 kgf/cm2). The burden of the bus was the opposite: to prevent the creation of too low a pressure inside the system. Both low and increased pressure are harmful to the car cooling system.

The modern coverage of the expansion tank – although it is different from the radiator’s hood – is similar to it. As a rule, two exhaust and suction valves are provided inside the plastic housing.

DOP DOP DOP VAS VAS VAS – 2108:

1. Arc The escape valve
2. Entrance valve
3. Arc The suction valve
4. Exit (steam valve)
5. Brass valve lock
6. The filling neck of the expansion ship.

The operational principle – Buson Vason’s expansion

Since modern engines have higher operating temperatures than those of previous generations, the discharge valves of the expansion ship can be open to pressure up to 1.5 kgf/cm2 and this parameter is rigorously regulated for each specific engine.

The suction valve opens at 0.03 – 0.13 kgf/cm2, which makes the void excessive in the system. Some producers combine two valves in one, but their essence does not change.

Until the pressure in the cooling system falls within the normal limits, the valves on the expansion ship do not work. As soon as the pressure exceeds the limit values, they act. The lid of the expansion ship is used not only to prevent the refrigerant from losing the tank, but also has the role of the pressure regulator in the cooling synthetic.

How many types are the hats of the expansion ship?

Usually for most modern cars there are covers for the expansion ship that are designed to work in the pressure field of 0.9-1.1 bar.

There are also covers for expansion vases designed to work at high pressure, in particular up to 1.3 bar. These hoods are particularly used in sports cars whose engines are designed to work in high power, but for a short period of time.

The coverage for the expansion vessels are of different types, depending on their geometric dimensions (the diameter of the lid, the diameter of the gasket, the resistance of the bow) and the premise for which they were designed.

The covers differ from one car brand to another, even if the operational principle is identical.

Defective symptoms of Buson Vason defective

It is quite difficult to identify a malfunction of the expansion ship and, due to the operational problems of the valve, serious problems can often arise.

However, there are several ways in which we can identify the breakdown of the expansion ship. Therefore, it is important to pay particular attention to the following symptoms:

• • The presence of smoke under the hood (see that the smoke comes out of the hood): It often occurs when the cooling liquid enters a hot suction gallery. In this situation, the engine temperature will be at a normal level but the antifreeze will burn again. The problem occurs when the valve works defective, it must lower the pressure when she is overcome, but it does not do it. In this case, the pressure begins to release before the best values, which leads to spraying with antifreeze.
  • The engine is boiling – You can see the increase in temperature above normal limits on board. It can also turn on the appropriate witness (see the material What they indicate on board bright witnesses).
  • At the start of the car, from air impacts you can hear a Unpleasant smell of burnt oil. It is possible that there is no smoke from under the hood, but you can expect white smoke to make its presence in a short time.
  • On the clips of the tube they appear Traces of antifreeze.
  • The terminals are broken.

• The cooling system is broken.

• • The pipes are compressed and do not let the cooling liquid pass.
  • The refrigerant tank it can also be save.

• The circulation of the antifreeze in the system is disturbed.

• The engine overheats but the radiator remains cold.

• • There are air pockets in the system that do not allow the antifreeze to circulate, for this reason The engine begins to overheat.

• The bush is expelled from the expansion ship.

Most of the time in such a situation it is necessary not only to replace the component, but also to repair other components of the cooling system. For example, if the radiator tube is broken, it must be replaced with a new one.

When is it necessary to change the composition of the ship?

In practice, it can often be seen that the high pressure valve in the compass compass of the expansion ship is the first at a defect. In fact, toosol or antifreeze are expelled through the valve even when the pressure is normal.

In addition, it happens not to release the pressure, the lid to break and the cooling fluid flows in the area of ​​the joints and joints. When the Boscaglia valves do not work anymore or, as in the previous case, when the lid is broken or broken, the expansion ship’s compass must be replaced with another to have the same size and the same parameters.
