Lubrication has a great influence on the performance of the drill, as well as the service life of the parts. Continuous lubrication should be ensured in the operation of the drill.Therefore, it is strictly prohibited to use inferior oil and waste oil, or use the large viscosity oil and lubricating oil that the injector cannot work, so as to avoid the bad lubrication caused by blocking the lubricating orifice or the air hole.
In addition, the use of large viscosity oil will also cause start-up difficulties.The principle of selection is that when the field temperature is high, the viscosity of oil is large.The viscosity of oil is small when the field temperature is low.When the site contains super gas, do not use the oil with low ignition point and easy to ship.
