Lubricating oil for construction machine
It is very important to use the lubricating oil of the construction machinery on the equipment, and it is also related to the working efficiency of the equipment. Sometimes, however, we have a variety of misconceptions about lubricants".
Misunderstanding 1: lubricating oil is always replaced
It is necessary to check the lubricating oil frequently, but it can not completely compensate for the loss of lubricating oil performance only if it is not replaced. In the use of lubricating oil, due to pollution, oxidation and other reasons, the qu
Misunderstanding two: additives are of great use
Really good lubricants have a variety of function of motor protection products, a variety of additives have been contained in the formula, including antiwear agent, lubricating oil and give full play to the most exquisite formula to ensure balanced performance. Adding other additives not only can not bring additional protection to the vehicle, but also reacts with the chemicals in the oil, resulting in the decline of the comprehensive performance of the engine oil.
Myth three: when the lubricating oil is black, it's time to change the oil
This understanding is not comprehensive. For no added dispersant lubricant, the black color is indeed a serious deterioration of the oil performance, but the use of modern automotive lubricants are generally accompanied by a quiet decomposition agent. This quiet agent will adhere to the piston glue film and carbon black washed down, and dispersed in oil, reduce the engine high temperature deposits, so the use of lubricating oil after a period of time to color black, but the oil is not completely bad.
Misunderstanding four: lubricating oil can be added more
The amount of lubricating oil should be controlled between the upper and lower scales of the oil dipstick. Because the lubricant is too much, it will break into the combustion chamber from the gap between the cylinder and piston to form coke. These deposits will increase the compression ratio of the engine, increase the tendency to produce knock; coke in the cylinder are red state but also easy to cause early burning, such as falling into the cylinder will aggravate the wear of the cylinder and piston, will accelerate oil pollution. Secondly, too much lubricating oil increases the resistance of the crankshaft connecting rod and increases the fuel consumption.
The above "misunderstanding" for lubricating oil, I hope you can correct this concept as soon as possible, in order to make your equipment better and more healthy work.
