The management of oil stock is mainly the three aspects of oil stock-in, storage and distribution. The purpose is to prevent the use of the wrong oil, mix of wrong oil and the occurrence of undesirable oil quality deterioration.

To store a certain amount of company-wide oil equipment in the warehouse, various grades of oil are needed to supplement the loss during operation. The oil can be replaced during maintenance and emergency oil use in the event of an accident. Moreover, it is necessary to ensure that various grades of oil have a certain amount (at least not less than the amount of oil used by the equipment that uses the most oil) to keep up to date.

New oil, degraded oil (used oil) and regenerated transformer oil must have test records when entering the depot. For each batch of new oil entering the depot, two oil samples must be taken at the same time, one for the international test, and the other for Keep it for future reference, at least 6 months. Except for the used oil to be regenerated, all the oil entering the oil depot should be pumped into the oil tank through the oil filtration machine to ensure the cleanliness of the oil pipeline and storage tank. The used oil to be regenerated is stored in special oil tanks and sent to the oil depot using special oil pipelines and oil pumps.

If spare oil is to be stored in oil drums, clean and dry oil drums must be used. When the oil is poured into the oil drum, close the lid tightly. Do not use internal and rusty barrels to avoid deterioration of the oil during storage. Oil drums should be placed in a dry and clean place, not in the open, otherwise they should be covered with a shed. Avoid rain and strong direct sunlight, and keep away from heat sources. In order to avoid accidents due to the large quantity and variety of stocked oil, (such as sending the wrong type of oil, etc.) all stocked oil tanks should be sealed with detailed record cards. Oil drums should be classified and stored in different brands. All oil tanks and oil drums must be clearly marked, and the accounts must be the same as the actual items.

It is forbidden to mix different grades of oil without testing, and it is even more important to prevent the mixing of new oil with old oil. If you mix different oils without a basis, the quality of the oil will be reduced, or even waste oil. Turbine oil and transformer oil should be stored separately, and the handling and storage equipment should also be separately dedicated to prevent mixing and sending.

The sealed oil drum should be opened when the oil temperature is close to the room temperature as much as possible to avoid condensed water due to the difference between the oil temperature and the room temperature, reduce the oil insulation strength and increase the trouble of oil filtration. In order to prevent moisture from affecting the oil quality, a moisture absorption device of calcium chloride or silica gel should be installed on the oil tank.

In order to detect abnormalities in stock oil in time, stock oil should be checked frequently. There are two types of inspection methods: regular and irregular inspections. Regular inspections are generally performed quarterly to check the quality, quantity and storage conditions of various oils. Simplified tests should be performed when checking the quality of the oil. Irregular inspections should be temporarily determined based on actual conditions, and focused inspections should be conducted for the problems found. In one of the following situations, inspections should be conducted:

1) When there is oil leakage, moisture and heat due to improper storage;

2) When the fluidity of the oil in the oil depot is very high and the oil management department is not easy to grasp certain situations;

3) When you have doubts about stock oil.

Regular and irregular inspections must be recorded, test reports must be written, and major issues issued during inspections must be recorded in the inventory oil card, and the oil management department shall deal with and solve them according to the inspection results.
