Fujian Excavator: Let's talk about the high engine oil and water temperature of small excavators
High engine oil and water temperature in small excavators During the construction and operation of construction machinery and equipment, high engine temperature or high water temperature is a common phenomenon. So, when the temperature of engine oil and water is too high at the same time, what should be done?
1、 High water temperature: How can the water temperature be too high?
The function of the water storage tank is to remove heat, and the function is to ensure that the heat is continuously channelled out through the engine fan.
Let's talk about the difficult problem of high water temperature:
1. The water temperature sensor is stuck and cannot be used. At this time, the water can only go through a small cycle and does not pass through the heat pipe radiator.
2. The inside of the water storage tank is dirty and the water is not smooth. This allows a thermometer to check the temperature of the left and right sides of the water storage tank. If it is blocked, the ambient temperature will be relatively low.
3. Insufficient fan revolutions, clutch failure.
4. "The sealing strip around the heat pipe radiator is damaged or missing, and at this time, vortices will occur, causing the warm air to be circulated through the system, unable to achieve the cooling effect.".
5. As for the fifth point, it is easy for everyone to overlook whether there is a false alarm or whether the sensor is broken. It is also very likely that the computer is very wooden, so just look at the data rather than the actual situation.
2、 High temperature
High temperature is similar to the problem of high water temperature, but there are also large and small cycles. Only if there is a pump oil throttle valve based on the water temperature sensor, if these valves are stuck, the temperature will be higher, and the other problems are the same as the temperature of water. Naturally, small excavators rely on the fan pump to drive the fan motor to adjust the rotational speed ratio. There is also an overflow type device, which generally has a high temperature. Checking these places can solve these problems, When the temperature of engine oil and water is too high at the same time, if the amount of oil and water is sufficient or scarce, the temperature should be lowered first, followed by precipitation.
Fujian Excavator: Safe Driving for Excavator Owners Operating Methods for Excavator Excavation and Trench Filling
During the excavation of the foundation pit, the excavator gradually reverses along the end of the trench and moves backward to excavate the foundation pit. The dump truck and car are parked at the ditch side, and the excavator only needs to turn over 40 ° to 45 ° to pour the material. If the excavation width is twice as large as the excavation half diameter of the excavator (that is, the excavator will excavate at a 180 ° turnover operation scale every time it idles), the dump truck and car must be parked next to the excavator, and the excavator boom must be rotated at 90 ° before dumping. If the excavation width exceeds twice the half diameter of the dry excavation, it is necessary to excavate the foundation pit in sections, that is, after the excavator reverses the excavation to the end, excavate the adjacent section of the foundation pit in the opposite direction at this end. The total width of each excavation section in this method is not suitable for being too large. Based on the principle that dump trucks and cars can travel on the trench side, it can reduce the moment of each working cycle and develop the output power in mechanical work.
Fujian Excavator: Safe Driving Method after Trench Excavation:
Excavators excavate the foundation pit on the side of the trench, cars receive materials at the end of the trench, and the excavator arm turns over and dumps materials below 90 °. The total width (trench width) of each excavation must be within the scope of its half operation. The disadvantage of this method is that the slope protection for excavation is relatively large.
Fujian Excavator: Alright, thank you for watching. If you need to purchase excavators, you can consult our company.

Fujian excavator introduces the operation method of large excavator
Fujian excavator introduces the operation method of large excavator. It is also a method-type technical work that requires several smooth postures, so the operators need to learn to use the swing method in addition to skilled training. I will talk to you about the swing methods of large excavators today.

Oil burning of large excavators is one of the serious faults of excavator engines. Oil burning of excavator engines means that the oil consumption of excavators is higher than that of excavators of the same model, and there is blue and black smoke during operation. The excavator manufacturer will take you to see how to deal with oil burning of large excavators?
