The selection of oil and antifreeze is very important when the engine of the muck loader is operating in the cold winter. The oil selection of the muck loader must be checked. It is not possible to use inferior oil to save a little money. Time will cause great damage to the muck loader, so we must insist on buying high-quality oil for the machine to use. With less machine failure, the profit will increase quickly.
Entering the cold winter, how should these big guys in construction machinery take care of them in the winter? The staff below will tell you the secrets of the muck loader in winter.
First of all, let’s talk about the choice of engine oil in winter:
1. Choose engine oil. Choose the engine oil produced by regular manufacturers. The machine and oil used are the same grade P, because the oil produced by the manufacturer is produced according to the nature of the machine.
2. It is necessary to select engine oil with appropriate viscosity according to different ambient temperatures. The use of residue loader engines is different from other equipment. Its heat dissipation performance is poor and the engine is under high-load working conditions for a long time, so the engine oil requirements are strict; The choice of oil should be selected according to different ambient temperatures.
3. Choose engine oil according to quality, etc. When selecting engine oil, the quality and other requirements must be met at the same time. The American Petroleum Association API standards are commonly used. Currently, there are CD, CE, CF-4, CG-4, CH-4, CI-4, etc. on the market , The quality is improved in order; CD, CE have been eliminated, CI-4 is now used in electronic injection engines; machine maintenance not only requires the choice of oil, but also requires strict regular exchange, which is also very important.
Secondly, antifreeze is indispensable in the cold winter slag loaders. If the mixing ratio of engine cooling water and antifreeze does not meet the requirements, the coolant will freeze and cause serious consequences of engine block rupture, so the choice of antifreeze And use the following two points:
1. The antifreeze used in the market today can be divided into two categories: ethylene glycol-standard service life antifreeze and propylene glycol extended use antifreeze, ethylene glycol (standard service life antifreeze) does not have Propylene glycol (extended service life antifreeze) has improved corrosion resistance. Therefore, propylene glycol should be used instead of ethylene glycol in antifreeze for muck loaders.
2. Do not mix ethylene glycol and propylene glycol, otherwise it will reduce the antifreeze performance. If the weather is not cold and the muck loader is parked for too long, please drain the antifreeze in the muck loader.
