1 The hydraulic oil deteriorates or the circuit is blocked. If the hydraulic oil used is not up to the requirements, it may cause the hydraulic oil temperature to be too high.
2. The oil level of the hydraulic system of the excavator is too low, when the excavator works below the specified oil level for a long time, especially when the hydraulic system is excessive and lacks oil, the hydraulic oil temperature will be too high.
3. If the hydraulic oil is circulated too fast and cannot be fully allowed to settle and clean the end, the oxidation and deterioration rate of the hydraulic oil can be accelerated, and the oil temperature will increase.
Troubleshooting Solution:
1 Replace the deteriorated hydraulic oil, use the hydraulic oil that matches the excavator or unblock the hydraulic oil circuit.
2 Add excavator hydraulic oil to the standard oil level.
3 Adjust the hydraulic pump pressure of the excavator.

It's not very clear, it's because the water temperature was low at the beginning, maybe the thermostat is broken; Do you mean that the temperature of the hydraulic oil is high, see if the cooling oil tank is blocked by dust, rinse it down, and wash or replace the hydraulic oil filter.

Hello. What is the reason for the high water temperature of the excavator Hello dear, <>
The reasons for the high water temperature of the excavator are: the coolant circulating water pump is faulty, and the water in the water tank cannot be circulated, resulting in high water temperature leakage; The excavator is covered with dust and sludge on the surface of the radiator, blocking the heat dissipation channel, and the lack of heat dissipation capacity leads to high water temperature; Clogging the radiator with substandard coolant or insufficient coolant refers to the section, resulting in insufficient heat dissipation capacity and high water temperature. Hope it helps.
Excuse me, my excavator water tank has just been replaced, so it will be hot.
Hello dear, <>
There are many reasons for the high water temperature of the engine or even "boiling", such as damage to the electronic components of the cooling system (thermostat, cooling fan), poor heat dissipation of the dispersion heater, and insufficient coolant.
But I used to have damaged electronic components, and I wouldn't have high temperatures.
Excuse me, there are several reasons for the high temperature, and the coolant has just been replaced.
Hello dear, <>
The reason for the high water temperature of the excavator is 1, the operating environment temperature is too high or the excavator is close to the heat source, which may cause the phenomenon, and the excavator is easy to appear in the summer operation, because the summer operating environment temperature is very high, so it is necessary to avoid long-term operation in the summer operation, and try to work as little as possible in the case of overload operation and too hot engine; 2. The heat sink of the excavator radiator is blocked by dust, and the heat dissipation effect is poor, and the excess heat cannot be discharged in time, resulting in high water temperature. To discharge faults, it is necessary to check the heat sink frequently and clean the heat sink; 3. If the thermostat is damaged or the thermostat is too small, it will also cause the phenomenon of high water temperature. 4. The water circulation of the excavator pump is not good, or the pump is damaged; 5. There are bubbles in the water tank, the water circulation is not good, and the cylinder gasket is caused by the punch, and the fault can be eliminated by replacing the cylinder gasket; 6. The excavator water tank is too dirty, there is too much scale, and the water circulation is not good; 7. The excavator fan belt is too loose and affects the circulation; 8. The coolant is not enough or the cooling system is wrong; It will also cause a high water temperature failure (the concentration of antifreeze ratio may be too large in summer); 9. If the engine cover is broken, it will also cause failure; 10. In addition, if the oil temperature of the excavator is too high, the operation time is too long, which will also cause the phenomenon of high water temperature; I hope it can help you Hongkai mill. <>
Excuse me, does engine oil have an effect?

Summary. Hello, the reason for the high water temperature of the excavator. Inaccurate ignition timing, insufficient engine power, and failure of the cooling system can all cause the engine water temperature to be too high.
On the excavators before the common rail EFI diesel engine, the hydraulic oil radiator was installed upstream of the cooling air in the water tank, so the overheating of the hydraulic oil could also cause the water temperature to be too high.
Hello, the reason for the high water temperature of the excavator. Inaccurate ignition timing of high volts, insufficient engine power, and failure of the cooling system will cause the engine to be too high in water temperature. In the excavator before the common rail EFI diesel engine, because the liquid Qishan with the pressure oil radiator is installed in the upstream of the cooling air of the water tank, the overheating of the hydraulic oil will also cause the water temperature to be too high.
Well, the hydraulic fluid is also hot.
Hydraulic oil temperature is too high: first of all, the hydraulic oil temperature is too high, according to the hydraulic theory and maintenance experience in recent years, the main reason for the high temperature of hydraulic oil is that the heat production is too fast and the heat dissipation is too slow. The hydraulic pump oil inlet pipeline and hydraulic oil tank are not tightly sealed, the oil inlet filter element is blocked, the hydraulic system pipeline is not smooth, and the internal leakage of the hydraulic pump will cause a large number of thermal bridge ridges to produce a large amount of hydraulic oil, so that the temperature of the hydraulic oil will rise rapidly due to excessive heat production.
The internal channel of the hydraulic oil radiator is blocked, the dust outside the radiator is too large, the wind is not enough, and the hydraulic oil does not pass through the hydraulic oil radiator, etc., which can lead to high temperature due to slow heat dissipation.
Mine may have the hydraulic oil not going through the radiator and going straight back to the tank.
There are several reasons for that: 1The radiator silver bypass valve is faulty, and the voltage regulation is low or often open; 2.The radiator back pressure valve is faulty, the pressure regulation is high or normally closed; 3.Blockage of the extremity segment of the foreign body inside the radiator.

The high water temperature of the excavator means that when the water temperature exceeds 95 in the work of the excavator equipment, the equipment will prompt an alarm, and the solution is to reduce the load, reduce the speed, and reduce the heat absorption; Increase the air inlet volume of the water tank to accelerate heat dissipation; After the temperature drops, check whether the antifreeze in the tank is missing and add antifreeze; When the temperature drops, clean the radiator.
The correct thing to do after the water temperature of the excavator is too high:
1. Load reduction, low speed, reduce heat absorption. Put the throttle of the equipment to the first gear to idle operation, so that the load of the equipment is reduced, the speed is reduced, and the heat generated by the friction of each moving part will correspondingly reduce the heat generated by the engine, and indirectly reduce the heat absorbed by the coolant, thereby reducing the speed of water temperature rise.
2. Increase the air inlet volume of the water tank to accelerate heat dissipation. Open the side doors on both sides of the excavator, so that the air volume of the radiator enters becomes larger, and the temperature of the cabin can be quickly dissipated, thereby reducing the speed at which the water temperature rises.
3. After the temperature drops, check whether the antifreeze in the water tank is missing, and add antifreeze. If you don't have a spare antifreeze nearby, you can add "pure water or distilled water for the rock people", and do not add river water or groundwater.
4. After the temperature drops, clean the radiator. After the temperature drops, check whether there is too much dust between the radiator, condenser and water tank, and clean it thoroughly with high-pressure gas to ensure that the water tank and condenser have good heat dissipation performance. Attention should also be paid to wiping the dust between the condenser and the water tank.
In fact, 80% of the high temperature of excavators is caused by poor heat dissipation. Therefore, thoroughly cleaning the debris on the surface of the radiator and the internal scale and oil scale is an important part of solving the high temperature of the excavator.

If the water temperature of our excavator is too high, the cause of the failure is because our water tank is dirty and blocked, resulting in poor water circulation. If we want to solve the problem, we need to clean our water tank and remove it to clean the water tank. Clean the dirt inside the water tank, and then install it back, you can solve our problem of high water temperature.
Here's wishing you a happy life and all the best! <>
How to solve the high water temperature of the excavator.
What is the reason for the high temperature of the excavator?
Hello boss, good evening. It's an honor to be here to answer your questions. If the water temperature of our excavator is too high, the cause of the failure is because our water tank is dirty and blocked, resulting in poor water circulation.
To solve the problem of Huaiyu, we need to clean our water tank and remove it to clean it. After cleaning the dirt in the water tank, and then installing it back, we can solve the problem of high water temperature. Here's wishing you a happy life and all the best!
Hello, dear, let's cover this excavator temperature is too high. The high water temperature is because of the different environments in which we use the tank, which leads to a lot of dirty things around our water tank, which affects the normal heat dissipation of our water tank. This caused the water temperature to be too high.
There is also a lot of dirt in the water tank. There are more impurities in the water, which leads to blockage inside the water tank, which can also cause this problem. If there is no problem, we can remove the water tank and clean the inside, clean the outside, and we can solve the problem of high temperature of the engine water tank system.
Qingbo Nian wash water tank. The use of ** is in this 200 to 230 yuan for disassembly and cleaning. **。
Cleaning the water tank can solve the fault phenomenon that our engine temperature is too high, dear. [Compare the heart] [compare the heart] [compare the heart] [compare the heart] [compare the heart].
Hello, dear, there is a second reason is because of us, the engine water pump water pump impeller is corroded and damaged, and there is no impeller. When our water pump is working, the water circulation cannot be carried out normally, resulting in poor water circulation, which causes the engine temperature to be too high. We also need to remove the pumps.
Check it, and if the impeller is damaged, a separate pump replacement can solve the problem. , through these two methods of maintenance to solve the problem of high engine temperature. Here's wishing you a happy life and all the best!

The discharge of your excavator hydraulic pump can be said to have a fixed discharge range, if you increase the discharge of the lifter, the throttle will definitely work fast, but the idle speed will hold the car and emit black smoke. If you turn the release down, the small throttle is also fine, and the high throttle strength will lack the speed. There is a manufacturer that specializes in treating this problem, and his principle is to collect the speed signal of the engine to control the discharge of the hydraulic pump, and the variable discharge of the proportional solenoid valve.
Power is a physical quantity, horsepower is a unit, there is no direct conversion of the reason. The unit of power is watts, and the conversion of watts and horsepower: 1 metric horsepower = 75 kgf·m-seconds = 735 watts. >>>More
Don't buy Doosan excavators, I regret buying them, I am an old driver who has been driving excavators for more than 10 years, and now I am the owner, Doosan's service is too poor, and the quality of the whole machine is not as good as before, everyone says that the current Doosan is not the previous Daewoo, and there are often a large number of excavators appearing, and the big arm is cracked. Cracking of the chassis. Lever handle oil leaking. >>>More
