What preparations should be made for small excavator in wint
Small excavators, also known as small excavators and small excavating machines, are very common construction machinery in life. The excavated materials are mainly sediment, pre loose soil, sediment, coal and rock. Today's small edition will introduce the relevant contents of small excavators in detail. Precautions for oil change of small excavator
1. Remember to change the engine oil regularly. This oil is equivalent to the blood of construction machinery. Every kind of oil needs to be replaced and maintained regularly. As a lubricant for normal engine operation, oil is no exception. The oil has been used for a long time, the oil viscosity is reduced, and poor lubrication and cooling lead to high engine temperature, and the cylinder piston is deformed under high temperature. In addition, in order to filter impurities in the engine oil, the oil filter element should also be replaced regularly.
2. Do not use inferior engine oil. When choosing to buy engine oil, do not buy inferior engine oil for the sake of cheapness. The quality of oil products will directly affect the service life of construction machinery and equipment. Poor engine oil can cause poor turbocharger lubrication, excessive wear, and poor air intake. It is recommended that you choose original accessories or replace them with original accessories.
3. Engine oils of different grades cannot be mixed with engine oils of different varieties. The chemical or physical additives added in the production process are different. Mixing different additives may cause chemical reactions. In addition, different grades of engine oils produced by the same manufacturer cannot be mixed, so they cannot covet such a small price.
4. The more oil you don't add, the better. There are many misunderstandings when changing the oil. The more oil you add, the better. More oil will cause great damage. First of all, too much oil will reduce engine output power and increase fuel consumption; Secondly, too much oil may damage the oil seal and cause the engine to leak oil.
5. Add a small amount of engine oil several times. How much oil is correct? How to refuel? Typically, the engines of small excavators are equipped with an organic dipstick. When filling oil, try filling several times. After about one minute, observe the dipstick and fill it several times to prevent excessive oil filling.
6. Small excavator is not equipped with proper fuel. High viscosity diesel oil is selected in winter, and low viscosity diesel oil is selected in summer.
7. The engine cylinder pressure of small excavator is insufficient, and the engine valve is not closed tightly.
8. Small excavator has difficulty in hot start. There may be a problem with the mini excavator oil pump or nozzle.
9. The diesel oil contains too much water or mixes with too much air, causing the fault.
10. Failure of solenoid valve of small excavator and wear of plunger of diesel pump will also lead to misfire.
