1、 Add as much lubricating oil as you can
The lubricating oil quantity of small concrete mixer truck should be controlled between the upper and lower scales of oil dipstick. Because the small mixer too much lubricating oil will rush into the combustion chamber from the gap between the cylinder and the piston to form carbon deposit. These carbon deposits will increase the compression ratio of small-scale mixer engine and increase the tendency to produce knock; the carbon deposit is red hot in the cylinder, and it is easy to cause early combustion. If it falls into the cylinder of small concrete mixer, it will aggravate the wear of cylinder and piston, and accelerate the pollution of lubricating oil. Secondly, the excessive lubricating oil of the small mixer increases the mixing resistance of the crankshaft connecting rod and increases the fuel consumption.
It is correct to check the lubricating oil of small concrete mixer frequently, but it can only make up for the shortage of oil quantity, but can not completely compensate the loss of lubricating oil performance
2、 When the blender oil turns black, it's time to change the oil
This understanding is not in place. For the lubricating oil without detergent dispersant, it is indeed a sign that the oil has deteriorated seriously. However, the lubricating oil used in small concrete mixer truck is generally added with detergent. This kind of detergent washes the adhesive film and black carbon deposits on the piston and disperses them in the oil, thus reducing the formation of high-temperature deposits in the engine of small-scale mixer. Therefore, the color of lubricating oil tends to turn black after using for a period of time, but the oil is not completely deteriorated.
3、 The lubricating oil of mixer truck is often added without changing
It is correct to check the lubricating oil of small concrete mixer frequently, but only replenishing and not changing can make up for the shortage of oil quantity, but can not completely compensate the loss of lubricating oil performance. In the process of using, the quality of lubricating oil of small mixer truck will gradually decline due to pollution and oxidation, and there will be some consumption to reduce the quantity.
The really excellent lubricating oil for small and medium-sized concrete mixer is a finished product with various engine protection functions, and the formula already contains a variety of additives
4、 Additives are of great use
The really excellent lubricating oil for small and medium-sized concrete mixer is a finished product with various engine protection functions. The formula already contains a variety of additives, including anti-wear agents. Moreover, the small-scale mixer lubricating oil pays attention to the balance of the formula to ensure the full play of various properties. Self adding other additives can not bring extra protection to small mixer, but easily react with chemical substances in engine oil.
