Specifiion

Description

The main function of the excavator's water tank is to dissipate heat, thereby reducing the temperature of the engine.

From the point of view of the structural principle, if the temperature of the excavator engine is very high, the thermostat will be turned on, and the water pump will pump water repeatedly, which will reduce the temperature of the excavator engine (the composition of the water tank is a There are hollow copper tubes, high temperature water enters the water tank and is air-cooled and circulated into the engine water channel) to protect the engine.
The main water tank also has an auxiliary water tank. The function of this auxiliary water tank is that when the engine water temperature rises, the water in the water tank will flow into the auxiliary water tank due to thermal expansion and contraction, until the temperature drops, the water will Flow into the water tank again, this process will not cause water shortage. When the water tank is short of water, the cooling capacity of the engine will be greatly reduced, and the ultimate goal of protecting the engine will be difficult to achieve. When this phenomenon occurs, it is necessary to check whether the auxiliary water tank is damaged or leaking.
Due to long-term work, scale will form in the water tank, which will reduce the heat dissipation capacity of the water tank to a certain extent, resulting in high temperature of the engine, suffoion of the engine and even boiling of the water. In this way, the engine is often injured, so we have to work every time. Check the heat dissipation capacity of the water tank, or replace it with the original pure antifreeze. The cooling effect of antifreeze is much better than that of water, and it is not easy to produce scale. It is necessary to use regular antifreeze. Do not mix water and antifreeze. , will increase the risk of tank clogging. If the water tank fails to dissipate heat properly, it is time to clean the water tank.

We turn on the drain switch of the radiator and unscrew the drain plug on the engine block to drain the liquid inside, then close the switch and install the plug, add water and some limescale cleaning agent to the radiator, the accessories store on the market It is generally available. The ratio of water and cleaning agent should be appropriate. Do not add too much. Too much will make it difficult to wash and increase the cleaning burden. Then start the engine to idle at a speed slightly higher than the idle speed, and when the water temperature reaches a green state, continue to run the engine for about ten minutes.

Characteristic

1.Core: The core is the largest part of the radiator. It’s a metal block that features the metal cooling fins that help vent the air. The core is where hot liquid releases heat and gets cooled before being sent through the process again.

2.Pressure cap: The pressure cap works to help seal the cooling system so it can remain pressurized. Coolant in the radiator is pressurized to prevent the coolant from boiling. It also keeps the system more efficient.
3.Inlet and outlet tanks: These tanks are where coolant flows in and out of the radiator and are loed in the radiator head. Hot liquid flows from the engine through the inlet tank, and once it is cooled, goes out through the outlet tank and back into the engine.
4.Radiator hoses: Coolant moves through the engine via the radiator hoses. They are important for connecting the inlet and outlet tanks to the radiator and the engine.
