Excavator summer heatstroke cooling measures - silencer modification

In the summer, the excavator spare parts is prone to oil temperature and water temperature when it is exposed to hot sunlight, which affects the normal performance of equipment.

Principle of action:

The muffler assembled at the front end of the exhaust pipe is installed next to the engine of the excavator. This has advantages and disadvantages. The advantage is that the temperature of the engine can be increased faster in the winter and the heat engine can be accelerated because the heat of the muffler can Conducted to the engine; but in summer it becomes one of the factors that aggravate the engine's water temperature too high. In summer, the temperature is high, and the engine exhaust will transfer heat to the hood when passing through the silencer. If the engine water temperature is too high, it will not work properly. It can also lead to accidents such as pulling cylinders.

Wrap the silencer with insulation material to effectively block the silencer from emitting heat into the hood. Hydraulic spare parts

Materials used: rubber-insulated cotton or glass wool, aluminum foil, super glue surface.

Production method: the insulating cotton is cut into a size that can be matched with the muffler, and the aluminum foil paper is attached and attached to the outer wall of the muffler, and the total thickness is about 10 mm.

Modified temperature test:

Working condition

The time is in early June, the location is in Anhui, the temperature of the day is 33 degrees, the construction conditions are the foundation of the excavation platform, the concrete of the surface layer needs to be removed first, which belongs to the condition of large engine load. Original excavator spare parts

At noon the day before the installation of insulation cotton, the measured temperature is 85 degrees, and the working temperature after installation is 77 degrees. It can be seen that there is a cooling effect of 5 to 8 degrees.

Security:

When the equipment is working, the temperature of the silencer is very high, and the rubber-plastic insulation cotton can only withstand the high temperature of more than 200 degrees. It does not rule out the situation that the rubber-plastic insulation cotton is burned or burned. Therefore, it is recommended that you still choose the resistance. Higher temperature glass insulation cotton or other materials. If you can't find glass insulation cotton, you can use the following method to test whether the rubber insulation cotton can withstand the silencer temperature of the machine you operate. https://jnjmzm.wixsite.com/sdjygcjx
