Wheeled mucking rock loader engine in the cold winter operation, the choice of oil and antifreeze is very important, a few days ago I visited the bazhaji company, the manager told the editor bazhaji in the choice of oil should be put on a good pass, can not save a little money and the use of low-quality oils, if a long time on the machine is very damaging, so many years the company insisted on their own purchase of good-quality oil for their own tunnel mucking machine use, machine Failure less natural profits also improve very quickly. So mucking rock loader oil selection is very important.
So these "big guys" in the construction machinery into the winter how to take care of it? Today I will discuss with you the winter oil selection considerations.
First talk about the choice of tunnel mucking loader engine oil into the winter:
Choose a regular engine oil to choose a regular manufacturer of engine oil, the use of tunnel mucking machine and oil is the same factory, because manufacturers produce oil is produced in accordance with the characteristics of the machine, so the good way is to use and their own mucking rock loader with the same factory oil.
Choose the appropriate viscosity of the engine oil according to different environmental temperatures bazhaji engine use is different from other equipment, its heat dissipation performance is poor and the engine is in a long-term high load working condition, so the engine oil requirements are stringent; the choice of oil should be based on the different ambient temperatures to distinguish between the choice.
According to the quality level to choose the engine oil oil selection at the same time to meet the quality level requirements, now commonly used American Petroleum Institute API standard, currently on the market CD, CE, CF-4, CG-4, CH-4, CI-4, etc., the quality of the order of sequential improvement; CD, CE has been eliminated, CI-4 is now used in the EFI engine;
The above points are the introduction of tunnel mucking machine oil selection, machine maintenance not only on the choice of oil requirements, and the need for strict regular exchange is also important.
Secondly, in the cold winter mini mucking loader antifreeze is indispensable, if the engine cooling water and antifreeze mixing ratio is not up to the requirements, the coolant will freeze and cause the engine block rupture of the serious consequences
So antifreeze selection and use should pay attention to the following two points:
Antifreeze used on the market today can be divided into two categories are ethylene glycol - standard service life antifreeze and propylene glycol - extended use of antifreeze, ethylene glycol (standard service life antifreeze) does not have propylene glycol (extended service life antifreeze) improved corrosion resistance, so mini mucking loader antifreeze should be used with propylene glycol instead of ethylene glycol.
Do not mix ethylene glycol and propylene glycol, otherwise it will reduce the antifreeze efficiency, if the weather is particularly cold, mucking rock loader parking time is too long, please tunnel mucking machine antifreeze inside the discharge clean.
