How to reduce the noise of the excavator engine?

1. When the small excavator is used, we should operate it strictly in the manual, so as to ensure that there will be no wrong operation, so as to ensure the good working condition of the small excavator, and there will be no noise.

2. There is also the fact that we should also check the parts of the small excavator after the end of each day's work, whether they are in good condition, because the parts with more serious wear will have more serious noise.

3. Of course, in addition to observing the integrity of the parts during the daily inspection, we should also check whether some parts are loose, and tighten them in time if there is.

4. Daily maintenance can not be forgotten, because in the daily maintenance, we can find some potential problems, so that they can be solved, so as to avoid the possibility of noise of small excavators.

As long as the mechanical part of the EFI engine can repair the engine, there are very few people who can repair the electronic control part, and there is no way to repair it, and the circuit board can only be replaced with a new one.

Summary. Hello <>

If the sound of the excavator pump becomes smaller, it is generally due to the following reasons: first, the fuel tank is insufficient and needs to be refueled; 2. The inlet of the oil pump is blocked and needs to be cleaned; 3. The pressure adjustment of the oil pump is not accurate, and it needs to be adjusted. Regarding the insufficient fuel tank volume, this situation is very common, you need to check the fuel tank oil level and refuel in time, otherwise it will lead to problems such as unstable machine work and quieter sound.

In addition, a blocked oil pump inlet is also a common problem, which can be eliminated by cleaning the air intake. Finally, inaccurate pressure adjustment also generally leads to a quieter sound, and the pressure of the oil pump needs to be adjusted to adapt to the current working state.

The excavator pump becomes quieter.

If the sound of the excavator pump becomes smaller, it is generally due to the following reasons: first, the fuel tank is insufficient and needs to be refueled; Second, the oil pump is blocked and needs to be cleaned up; 3. The pressure adjustment of the oil pump is not accurate, and it needs to be adjusted. Regarding the lack of fuel tank oil, this situation is very common, you need to check the fuel tank oil level and refuel in time, otherwise it will lead to problems such as unstable machine work and quieter sound.

In addition, the blockage of the inlet of the oil pump is also a common problem in the limb plexus, which can be eliminated by cleaning the air intake. Finally, inaccurate pressure adjustment also generally leads to a quieter sound, and the pressure of the oil pump needs to be adjusted to adapt to the current working state.

In addition to the above reasons, the sound of the excavator's large pump is reduced and there are other generalities, such as oil circuit blockage, oil pump gear damage and so on. If the above methods are eliminated and the problem is still not solved, it is necessary to carry out a deeper oak late entry inspection. For example, disassembling the oil pump to clean the fluid closure or replacing the oil pump gears requires specialized skills and tools and is not recommended for non-specialists.

In addition, paying attention to the maintenance and maintenance of the excavator can also effectively reduce the probability of problems with the machine. <>

1.Carbon deposits can cause insufficient combustion of gasoline and cause the engine to shake. The impact of engine carbon deposition on the car is quite large, first of all, it reduces the engine power, that is, the power output is uneven and gradually decays, in other words, it is more and more weak.

The second is to increase fuel consumption and increase your financial burden. The third is the difficulty of cold start, that is, the difficulty of ignition, it is not easy to get on the car, and finally the carbon deposit in the combustion chamber is strict, and a heavy one will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, and cause high temperature of the engine, which will seriously affect the safety of the car. Then the emission exceeds the standard, which not only fails to pass the annual inspection and inspection, but also directly aggravates the harm of polluting the environment 2

The load operation of the gearbox will destroy the quality and friction characteristics of the gearbox oil, increase the friction and wear, and the transmission noise will follow, and at the same time, the sludge (impurities or dirt) will also be generated inside the gearbox (such as the valve body), resulting in the gearbox stuttering, out-of-gear, impact, slippage, abnormal sound, delay, high temperature, and oil leakage. (Audi and other high-end models will call the police and enter the transmission protection mode) If it is not solved in time, the transmission will be scrapped. Therefore, only by removing the stubborn dirt and impurities in the gearbox and effectively controlling the working temperature of the gearbox can the gearbox problem be completely solved and prevent its recurrence.

3.Decreased lubrication leads to mechanical wear.

Hello dear, glad to answer for you! Based on your description, you can follow the steps below to look for the existing problems:1

Diagnosis of the motor: The sound phenomenon of the large pump of the key hall excavator may be caused by the motor, and it can be diagnosed by checking the insulation, temperature rise, coil burnout and other reasons of the motor. 2.

Check the condition of the lubricating oil: the sound of the large pump of the excavator may also be caused by poor quality of lubricating oil or insufficient lubricating oil, to ensure that the quality of the lubricating oil and the quantity of lubricating oil in the machine are sufficient. 3.

Replace the valve: The sound of the pump can be reduced or the lack of energy is caused by the valve problem, and the valve should be replaced to solve this problem. 4.

Check the filter: The filter may become blocked, causing the pump to be quieter. Therefore, the filter should be checked and replaced in time if the filter is blocked.

With the above suggestions, you can find the specific cause and propose a corresponding solution, hopefully to help you.
