How to check for water in excavators during the rainy season and how to deal with it After heavy rainfall water ingress in excavator equipment is a common phenomenon, the main reason for this type of situation is due to rainwater flooding the machine, especially in scenarios such as construction sites, where such events can easily occur. To deal with this situation, we need to take a series of correct measures to protect the equipment and get back to work in the shortest possible time. As there are many reasons for the failure of excavators, so we have to first determine whether the excavator failure is caused by water ingress, the following is to give you a compilation of equipment into the water judgment method: 1. Check whether the tyres or tracks of the machine are heavy. Excavator into the water, the tyres or tracks will be waterlogged inside, resulting in heavy tyres or tracks inflexible when the machine is driving。 2. Check whether the oil of the machine is deteriorated. After the excavator is in water, the internal lubricating oil and hydraulic oil of the machine will be affected, and the oil will deteriorate and become cloudy. 3. Observe whether the appearance of the excavator is abnormal. After water ingress, the surface of the machine will leave obvious water marks or water stains, especially at the seals and recesses. 4. Check whether the electrical system of the machine is faulty. After the excavator is in water, the electrical system is prone to malfunction, such as failure to start, control system failure and other phenomena. 5. Check whether the machine has abnormal sound. After the excavator into the water, the machine internal electrical, oil pipe and other components will produce abnormal sound, such as noise, breathing sound, etc.. Once there is a strange sound may be a more serious problem. These are the basic methods to determine whether water is entering the excavator. If the above phenomenon occurs, it is recommended that the following steps should be followed: 1. Turn off the excavator, after finding water in the excavator equipment, it should be turned off immediately. This will avoid further damage and safety hazards. 2. Check the electrical system. Water ingress may cause damage to the excavator's electrical system. Therefore, the electrical system should be checked for impact and the necessary repairs and replacements should be carried out. 3. Check the hydraulic system. The hydraulic system of the excavator is very important and water ingress may cause serious damage to it. Therefore, the hydraulic system should be checked to see if it has been affected and the necessary repairs and replacements should be carried out. 4. Replace the lubricating oil and hydraulic fluid, as water ingress can contaminate the lubricating oil and hydraulic fluid and should therefore be replaced promptly. 5. Check the filters, as water ingress may cause them to become clogged or damaged, and carry out the necessary repairs and replacements...

What is the reason for the sudden shutdown of the excavator or the failure to increase the throttle? When you are doing intense excavation work, if the excavator suddenly shuts down, it can cause you a lot of trouble. Especially in some time-critical work, this situation will lead to delays in the progress of the project, and even need to spend more time and money to repair the excavator. When dealing with flameouts and throttle failures, we need to figure out what's causing the failure. Here OTTO will sort out some reasons that may cause the excavator to stall or the accelerator cannot be added: 1. Fuel oil passage blockage: The blockage of the fuel oil passage means that some substances that hinder the flow of fuel appear in the fuel system of the engine, which causes the fuel to not flow normally into the combustion chamber of the engine. If the fuel oil passage is blocked, the fuel cannot flow smoothly into the combustion chamber of the engine, resulting in insufficient fuel supply, and the engine will stall due to lack of fuel. Moreover, the blockage of the fuel oil circuit may also cause other failures, such as oil pipe rupture, fuel injector failure, etc., thereby affecting the normal operation of the engine. 2. The air filter is clogged: The air filter element of the excavator is usually used to filter dust and impurities in the air. If the air filter element is severely clogged, the intake air volume will be reduced, the engine power will be reduced, and the engine cannot get enough air, which may cause the excavator to stall. If the air filter element is found to be blocked, it should be cleaned or replaced in time to ensure that the engine can work normally. 3. The fuel injection pump of the fuel injector is stuck: When the engine fuel injector or fuel injection pump is stuck, the fuel injector cannot work normally, and the fuel cannot enter the cylinder smoothly. This will cause the engine to fail to operate normally, causing problems such as power drop, engine overheating, and even engine stalling in severe cases. Therefore, if the engine fuel injection nozzle or the fuel injection pump is stuck, the excavator should be stopped immediately and repaired. If you need to replace the fuel injector or fuel injection pump, you should use the same parts as the original ones to ensure that the engine can work normally. 4. The pump regulator is stuck at the maximum displacement position: A stuck excavator pump regulator at maximum displacement can cause engine failure and potentially cause the excavator to stall. When the excavator is working normally, the pump regulator controls the working speed and strength of the excavator by adjusting the output power of the oil pump. If the pump regulator is stuck at the maximum displacement position, it means that the output power of the oil pump is limited to the maximum value, which will lead to insufficient engine output power, thus affecting the normal operation of the excavator. 5. Electronic thro...

The Spring Festival is an ancient festival in our country, and it is also the most important festival of the year. How to celebrate this festival has formed some relatively fixed customs and habits in the historical development of thousands of years, and many of them are still passed down to this day. clean--------OTTO Excavator Company "The twelfth lunar month twenty-four, dust and sweep the house", according to "Lu spring and Autumn" records, the Spring Festival dust custom in my country was in the era of Yao and shun.
