Small excavator winter maintenance skills

Small excavator, also known as small excavator and small excavator, is a very common construction machinery in life. Excavation materials are mainly sediment, pre-loose soil, sediment, coal and rock. Today, the editor will introduce the relevant content of the small excavator in detail. Precautions for oil replacement of small excavator.


1. Remember to change the engine oil regularly. This oil is equivalent to the blood of construction machinery. Every type of engine oil requires regular changes and maintenance. As a lubricant for the normal operation of the engine, engine oil is no exception. The oil has been used for a long time, the viscosity of the oil will decrease, poor lubrication and cooling will cause the engine temperature to be too high, and the cylinder piston will be deformed under high temperature. In addition, in order to filter the impurities in the engine oil, the oil filter element should be replaced regularly.


2. Do not use inferior engine oil. When choosing to buy motor oil, don't buy low-quality motor oil just because you want to be cheap. The quality of oil will directly affect the service life of construction machinery and equipment. Poor quality engine oil can cause poor turbocharger lubrication, excessive wear and poor air intake. It is recommended that you choose original accessories or replace pure original accessories.


3. Engine oils of different grades cannot be mixed with engine oils of different varieties. There are different chemical or physical additives added during production. Mixing different additives together can cause chemical reactions. In addition, different grades of engine oil from the same manufacturer cannot be mixed, so they cannot covet such a small price.


4. The more oil the better. There are many misconceptions about changing the oil. The more oil you add, the better. More oil can do a lot of damage. First of all, too much oil will reduce the engine output power and increase fuel consumption; secondly, too much oil may damage the oil seal and cause the engine to leak.


5. Add a small amount of oil several times. How much oil is correct? How to refuel? Usually, the engine of the mini excavator is equipped with an organic oil dipstick. When adding oil, try adding several times. After about a minute, watch the dipstick and top up a few times to prevent overfilling.


6. Small excavators are not equipped with suitable fuel. Use high-viscosity diesel in winter and low-viscosity diesel in summer.


7. The engine cylinder pressure of the small excavator is insufficient, and the engine valve is not closed tightly.


8. It is difficult to start the hot car of the small excavator. The mini excavator oil pump or nozzle may be faulty.


9. Diesel contains too much water or diesel is mixed with too much air, resulting in failure.


10. Small excavator solenoid valve failure and diesel pump plunger wear can also cause misfire.


This is the end of the introduction of the winter maintenance skills of small excavators. I hope it will be helpful to everyone. If you have any questions, please feel free to consult.

Causes of crawler excavator pipe burst

Crawler excavators are very common in our life, but in the process of use, pipe bursts often occur, so what are the factors that cause this phenomenon? The following crawler excavator manufacturers will give you a detailed explanation: 1. Use inferior hydraulic pipes For the sake of cheapness, many people choose inferior crawler excavator hydraulic pipes that do not meet the standards. The performance and reliability of the hydraulic pipes are far lower than the original pipes, and the sealing and reliability cannot be guaranteed. After a period of use, fuel consumption and even oil leakage will occur. Therefore, it is necessary to choose an ordinary big brand product to replace the hydraulic pipe. 2. Excessive pressure in the hydraulic system will increase the possibility of bursting. This method is used to test the pressure and various actions generated by the main pump. If it is confirmed that the pressure value is too large, the pressure of the multi-way valve can be appropriately ...

Precautions for leveling the ground with small excavators

Leveling a small excavator is one of the skills that a driver must master, and it is very important to master certain essentials of action. This article provides a theoretical basis for novices. Let's take a look at what knowledge a small excavator operator needs to have when leveling an excavator. Essentials of excavator leveling action: 1. On the land to be leveled, first visually measure the height of both ends of the ground, then find the elevation point from the high end of the ground, level it in turn towards the low-lying end, and finally dig out the soil higher than the elevation point and fill it up. In low-lying areas, it is visually level. 2. When the excavator lowers the boom, open the second arm until the angle between the boom and the boom is about 45 degrees; open the bucket so that the mouth of the bucket and the boom of the second arm are basically in a horizontal state; the bucket falls to the ground and retracts the second arm, lift The big arm pulls the soil bac...

Excavator maintenance method

Thank you very much for your question. The following is the relevant information about the maintenance method of the excavator. daily cleaning During the use of the excavator, it will be eroded by a large amount of dust, mud, sand and other impurities, which will accelerate the wear and corrosion of the machine. Therefore, in order to prolong the service life of the excavator, daily cleaning is very important. Specific methods include: Use a high-pressure water gun to clean the surface of the machine, especially the inside of the machine and the surface of the radiator. When cleaning the radiator, care should be taken not to point the high-pressure water gun directly at the radiator chip to avoid damage. After daily use, the machine should be cleaned and inspected briefly to ensure that the machine is in good working condition. Lubrication and maintenance Lubrication maintenance is an important part of excavator maintenance. Improper lubrication will lead to parts wear, oil leakage and...

Excavator service life

It is our pleasure to provide you with information about the service life of excavators. First, the service life of an excavator depends on several factors, including but not limited to the following: Use environment: The service life of the excavator will vary greatly under different use environments. For example, an excavator will last longer if it is used in a dry, clean environment than if it is used in a wet, messy environment. Maintenance: Regular maintenance and repair of the excavator can effectively prolong its service life. If maintenance and repairs are neglected, various parts of your excavator may suffer damage or wear, shortening its lifespan. Frequency of use: The frequency of use of the excavator also has a great impact on its life. If heavy work is performed regularly, the various parts of the excavator may wear out more quickly, shortening its lifespan. Generally speaking, the service life of the excavator can reach more than 5000 hours. However, the specific service ...
