Excessive engine water temperature is a common fault in excavators. Under normal engine operation, the water temperature is generally set between 82 and 95 °C.  Excessive water temperature will affect the normal performance of engine power and shorten the service life of the engine. In response to this common phenomenon, the editor today introduces several common causes of excessive water temperature. 1. The machine is in an overloaded state for a long time, especially in a high-temperature environment The high external temperature reduces the heat dissipation efficiency of the engine cooling system, and the engine continuously generates new heat, resulting in heat accumulation in the body. The water temperature is too high. 2. Long-term use of water with high hardness or impurities Calcium and magnesium ions or impurities in the water will precipitate at high temperature and adhere to the inner surface of the water tank and water pipeline, forming scale. Scale will hinder the water flow and even block the pipeline, which will affect the operating efficiency of the heat dissipation cycle, affect the heat dissipation, and reduce the efficiency of the heat dissipation system. 3. If the radiator is not cleaned for a long time, a lot of dust will adhere to the surface of the radiator, which will affect the heat loss of the radiator The radiator is the most direct heat dissipation device of the heat dissipation system. It is very important to ensure that the surface of the radiator is clean so that it can dissipate heat efficiently. 4. The thermostat is faulty The thermostat is the core component of the heat dissipation system that senses and adjusts the temperature. If the thermostat is damaged, the heat dissipation system will not be able to switch between large and small cycles according to the water temperature. When the water temperature rises, it will not be able to switch to the large cycle heat dissipation in time, resulting in excessive water temperature. 5. Insufficient water The water in the heat dissipation system is the transport carrier to bring the heat inside the engine to the radiator. Too little water directly affects the heat transfer efficiency. 6. The cooling fan blades are deformed and the belt is loose The excavator engine is installed in a relatively airtight engine room. If the cooling fan cannot discharge the heat from the radiator and the body out of the engine room in time, the heat will accumulate in the engine room and affect the cooling efficiency of the engine. 7. The water pump is damaged The water pump is the power source for the heat dissipation cycle operation. If the water pump is damaged, the efficiency of the heat dissipation cycle will be reduced or even stop running, resulting in an increase in water temperature and even damage to other components. It is worth noting that the high engine water temperature is sometimes not only caused by one or two of the above factors, but the result of a combination of various factors.  Therefore, we must learn to make comprehensive judgments. So how do you usually prevent the engine water temperature from overheating?  First of all, do not use water with high hardness or impurities when adding water. Try to avoid long-term overload operation in a high temperature environment, clean the radiator surface frequently, keep the cooling fins clean, and check the cooling fan and belt regularly. The engine is the heart of the excavator, and its working condition has a significant and direct impact on the working condition of the whole machine. Once the water temperature of the engine is overheated, the cause should be checked in time, and the faulty parts should be repaired or replaced in time to avoid damage to important components and cause heavy losses.

1. Wear personal protective equipment Always wear a hard hat and safety shoes. When operating or maintaining machine, wear safety glasses, face shield, gloves, earplugs, and seat belt if the job requires it.  Before use, check that all protective devices are functioning properly. Do not take chances, so as not to increase unnecessary danger. 2. Get on and off the machine correctly When getting on and off the machine, always face the machine and use the handrails and steps marked with arrows in the figure below.  Keep three points (two feet and one hand or two hands and one foot) in contact with handrails and steps (including track shoes) to ensure that you support yourself. 3. Start the machine safely Check the engine coolant level, fuel and oil levels before starting the engine. Check the air filter for clogging. Verify that the safety lock lever is in the locked position. 4. Make sure that no one is above, below, and around the machine, and honk the horn as a start-up warning. Start the engine strictly according to the operating instructions in the operation and maintenance manual to avoid machine damage or casualties caused by wrong operation.

We currently use the most industrial cleaners may still be in the production, may be a lot of people do not know some of our large-scale equipment also needs to be cleaned, because large-scale equipment operating time is too long, its surface will have a lot of dirt. If not cleaned in time, may affect the efficiency of the work, damage the service life of the machine. Therefore, the cleaning of industrial equipment is still very important, and still mainly to remove the oil. Currently the most common industrial cleaning is ultrasonic degreasing cleaning because it is more efficient compared to high temperature heated tank cleaning. It uses the principle of ultrasonic vibration to accelerate the shedding of oil, but also has a heating tank cleaning-heating function. Therefore, advanced ultrasonic cleaning is rapidly replacing the traditional heating tank cleaning. There are many industrial degreasing cleaning processes and many industrial cleaning agents, so we need to pay attention to the following 3 points in the selection of degreaser: 1. Choose the degreaser with high efficiency and strong decontamination Verify the reliability of the product, it is necessary to test or sampling 2. In addition to the quality of the product itself is excellent, for due service should also be concerned Many people will ignore this point. In fact, today, the choice of degreaser and services are almost equally important. Without reliable pre-sale, after-sale and technical services, once the problem occurs, it is easy to cause big losses. 3. It is also important to choose environmentally friendly and non-polluting products Currently, many companies are also the top priority of the national requirements, a series of policies are strictly around the green power.

Preventive maintenance is one of the best things you can do for your heavy equipment. Some of its benefits include reducing expenses, extending the life of your equipment, and ensuring that your company can always use more of it. Because heavy equipment maintenance can provide so much value, many savvy businesses prioritise it. 1. Extended Life When you perform routine maintenance on your construction equipment, you keep it in tip-top shape so that it can be used for a long time without breaking down or needing major repairs. Performing preventive maintenance can keep machines running longer than those that are not regularly serviced and maintained. Longer service life is a major benefit, as it maintains productivity in the workplace and avoids downtime for repairing or replacing faulty machines. 2. Increased Safety Generally speaking, well-maintained construction equipment is safer than neglected machinery. If equipment malfunctions at an unexpected time, a nearby worker or operator could be seriously injured. In addition, equipment failure can damage surrounding property and other materials or equipment. Routine maintenance helps you keep an eye on any potential hazards and repair problems before they become serious. 3. Reduced expenses Unexpectedly damaged or malfunctioning equipment can incur some unexpected costs. While you can't prevent every machine breakdown, you can reduce the chances of failure through preventive maintenance. Compound failures and other major breakdowns are more likely to happen unexpectedly if you don't maintain your equipment on a regular basis. With regular maintenance, you can save money because you won't have to pay for replacement parts or lose productivity while waiting for your equipment to be repaired. 4. Reduce the risk of lawsuits If you don't regularly maintain and repair your equipment, you face potential lawsuits. Unmaintained equipment can break down at the worst possible time, leading to accidents that injure employees or damage your building. Whether it's a lawsuit from an injured employee or a disgruntled customer, you want to avoid equipment negligence and its consequences. Having a regular maintenance schedule in place can prove that you've done your due diligence.
