Failure details: A Carter 320 excavator has a high temperature in the summer at 35 degrees. The water tank and radiator of the excavator have been cleaned or the temperature is still high. What is going on? The following Master Yang of Merritt will answer this question for the family!
Common cause analysis of Carter 320 excavator engine high temperature failure: motivation load, hydraulic leakage, poor fuel injection nozzle, insufficient air intake of the engine itself, water channel fouling, low heat dissipation efficiency, etc. may cause high temperature failure of the excavator engine. Fan belt too Loose will also be high temperature. It may be that the heat dissipation of the engine is not good, so focus on checking whether the heat dissipation and the water jacket are smooth. As for the other, the heat dissipation equipment, other hydraulic pressure, transmission, etc. have nothing to do with the air conditioning. , Also because he hinders the heat dissipation of the radiator. The tension of the belt is also very important.
Fault inspection and maintenance:
It is recommended to add a small water tank for the high temperature of the excavator engine, find a water tank with an electronic fan on the mini car, install it on the excavator, connect the excavator warm air pipe to the small water tank, and connect the upper warm air pipe to the small water tank. Port, below the 12V power supply connected to the battery, press a switch. Check the oil pump fire level, and oil pump flow, check the cylinder gasket to see if there are bubbles in the water tank.
When the temperature of the excavator engine is high, first check whether the shutters are fully open, whether the cooling water is sufficient, and whether there is also added last year's antifreeze, which will also reduce the boiling point of the cooling water, thereby reducing the cooling effect of the cooling water. Increase the engine speed to the highest level, and gently hold the upper water pipe with one hand. If you can feel rhythmic vibration, the pump is working normally. If there is no or the rhythm is not strong, it means that the pump is not working or is weak, and the pump is damaged. Check The belt, if you turn on the air conditioner, it will heat up. Turn off the air conditioner immediately, and move the condensation plate of the air conditioner to the outside.
