Lubricating oil generally consists of two parts of the base oil and additives. Base oil is the main component of lubricating oil, determines the basic properties of lubricants, additives can make up for and improve the performance of the base oil deficiencies, given some new properties, is an important part of lubricants.

 Lubricants drums and drum lubricants should be stored in the warehouse to the extent possible to avoid being affected by the weather and the drum oil must be stored in the warehouse. Oil drums lying to appropriate, both ends of the barrel wedge must be wedges to prevent rolling. In addition, check whether there is any leakage of oil drum and whether the sign on the surface of the drum is clear. If the tank must be directly opened, it is advisable to invert the tank so that the tank cover is downward or the tank is slightly inclined so as to prevent rain water from accumulating on the tank surface and flooding the bucket. Water has an adverse effect on any oil.

On the surface, it is not easy for water to penetrate the complete lid into the oil drum, however, the oil drums stored in the outdoors are exposed to the sun during the day and the cooler weather at night. Such thermal expansion and contraction of Suzhou Lubricant will affect Barrel air pressure; daytime slightly above atmospheric pressure, at night is close to the vacuum. This change in day and night pressure will have a "breathing" effect, during the day part of the air is "exhaled" outside the barrel, the night air was "sucked" bucket, if the bucket is immersed in water, then the night will inevitably with the air moisture Into the barrel, over time, the water mixed in the oil is quite considerable.

Oil extraction, the oil drum should be lying on a suitable height of the wooden frame, with the lid at the top of the bucket with the oil drain, and put a container under the tap to prevent spills. Or insert the drum directly into the tubing through the lid of the barrel to pump the oil through the hand pump.

 Bulk oil stored in the tank will inevitably have condensation of water and dirt incorporation, and ultimately gathered in the bottom of the tank to form a layer of sludge-like substances, so that lubricants contaminated. Therefore, the design of the bottom of the tank with butterfly butterfly or tilt appropriate, and install the drain cock to drain the residue on time. Where possible, the interior of the tank should be cleaned regularly.
