The water tank plays an important role in cooling and dissipating heat during the operation of Volvo diesel generator set. If you think about the improper application, the heat cannot be reduced, which will cause the expansion of the water tank of Volvo diesel generator set to be damaged, and the failure of normal use will cause unnecessary consumption.
The reason for the expansion of the water tank of Volvo diesel generator set is that when the diesel engine is operating under load, the coolant often boils on the cooling surface in the high temperature area, generating steam bubbles. When the steam bubbles increase and become one piece, a steam pocket is formed; In addition, when the water pipe joint or water pump itself is poorly sealed, air will leak into the cooling system and form an air bag; Due to the high combustion pressure of the diesel engine and slight poor sealing of the cylinder gasket, gas is prone to seep into the cooling system from the cylinder and form a gas bag.
Under normal circumstances, these gases can be discharged from the water cap. If these gases cannot be discharged, they will form an air lock in the cooling system, which will cause insufficient water supply to the water pump, reduce the flow rate and pressure of the water, and worsen the cooling of the cylinder liner, resulting in pitting corrosion. The residual air can also cause local uneven cooling and faults such as cooling oxidation and corrosion of metals. The expansion tank is used to discharge the above gases and eliminate the air lock of the cooling system. Let the coolant have space to expand the body on the cooling circuit, which is completed by the expansion tank.
Expansion tank is also called additional water tank or elevated water tank. It is a water tank with a small volume and a high installation position, which is connected in parallel with the radiator in the water circuit of the cooling system. During operation, part of the coolant flows through the expansion tank to separate air and water. This part of coolant flows through the expansion tank, which is called degassing circulation.
Therefore, the water tank is extremely important in the cause of the expansion of the water tank of Volvo diesel generating set, and the fault should be found and solved in time. Starlight reminds everyone that when operating the cause of the expansion of the water tank of Volvo diesel generator set, there should be professional personnel for operation and relevant technical training, so as to better solve the problem.
