How to choose diesel grade for rotary drilling rig

Winter construction rotary drilling rigs should be equipped with a bottle of starting fluid, and fuel can also be selected according to the temperature. Currently, the vast majority of rotary drilling rigs use diesel engines, and the editor has collected some information for everyone's reference.

The basis for dividing diesel grades is the freezing point of diesel. Currently, the light diesel used in China is divided into 7 grades according to the freezing point:

10 # Diesel: Suitable for high-speed diesel engines with preheating equipment;

5 # Diesel: Suitable for use when the temperature is above 8 ° C;

0 # diesel: suitable for use at temperatures between 4 and 8 degrees Celsius;

-10 # Diesel: Suitable for use at temperatures between 4 and 5 degrees Celsius;

-20 # diesel: suitable for use at temperatures between -5 and -14 degrees Celsius;

-35 # diesel: suitable for use at temperatures between -14 and -29 degrees Celsius;

-50 # Diesel: Suitable for use at temperatures between -29 and -44 or below.

Yahe Heavy Industry's small rotary drilling rig manufacturer suggests that everyone pay more attention to weather forecasts and choose different grades of fuel according to the appropriate temperature.
