I-40A Industrial Oil: Protection from Contamination in Storage

The main area of application of I-40A industrial oilis in hydraulic equipment such as automatic lines and presses.  Since these machines are quite common, I-20A oil has become rather popular with equipment operators. After purchasing oil, it is important to protect it from contamination.  Our website has reviewed various protection measures for industrial oil the oil oil is in operation, now we want to focus on protecting oil while in storage. One of the most efficient measures to prevent contamination of I-20A industrial oil in storage is to keep it out of contact with air.  This can be done by removing gas from storage tanks entirely.  This is done by storing oil in flexible tanks or tanks with floating lids. Flexible tanks are mostly used for the temporary storage of oil.  This is due to simplicity of their transportation and deployment. Floating lid tanks can significantly reduce oil losses.  They do not however, protect industrial oil very well from dust.  When the lid lowers, dust settles on the walls of the tank and enters the oil from there.  Additional problems arise in winter after significant precipitation.  Water is difficult to remove from the lid’s surface.  In Winter, a floating lid is often suspended in the upper position.  The tank then functions as a regular vessel.  This circumstance prevents extensive use of such reservoirs in colder regions. Tanks with a floating pontoon are free from this type of drawback.  Besides, they are significantly simpler, cheaper and lighter than floating lids.  Polymer pontoons are the most promising.  Development of chemical technologies leads to constant reduction of cost of polymeric materials for the pontoons. Another approach is to use tanks that do not entirely remove the empty space, but reduce its size.  Tanks with variable gas space can be divided into reservoirs with a breather, a gas cylinder and membrane roofs. Tanks with breather roofs, although of simple design, can only be used for long-term storage of industrial oil with low vapor pressure when the tanks are full.  The volume of this type of tank can only vary by no more than 3% to 5%. Gas cylinder tanks are more complex, but can be partially filled, since their volume may change by 8% to 12 %.  It should also be remembered that gas cylinder tanks cannot be used as consumption tanks. Tanks with membrane roofs are not widely used due to the complexity of their design. The “Gas Space” in oil storage tannks can be reduced by using the water cushion storage method. The advantage is the ability to use existing tanks.  The changes of the design are slightand include piping, pumps and a water tank.  The volume of the gas space therefore, will be insignificant and constant because the decrease of oil level is compensated immediately by the same amount of water pumped under the product.  The primary disadvantage of this method is the potential and possibility of water mixing with the oil. To prevent the appearance of microbiological contaminants in the oil, the oil is subjected to UV radiation, electromagnetic fields, or heat.  These methods however, are not widely used due to their temporary effects that do not prevent subsequent contamination of the oil with microorganisms.
