Can oil filters ensure the stability of oil products
2018/5/17 Viewers:
Under certain external conditions, the ability of oil to resist oxidation is known as the oxidation stability of oil, or the oxidation stability. How much is the amount of sediment and acid value in the oil? The principle of determining the oxidation stability of oil products is that a certain amount of test oil is installed in a special glass oxidation tube, which is used as a catalyst to add a certain specification of metal to a certain temperature, and keeps a constant flow of oxygen or air for a certain period of time, that is, to accelerate the oxygen of the oil by artificial method. The acid value and the precipitate of the oxidized oil are then determined. The oxidation and stability of the oil with poor oxidation stability will change the physical and chemical properties of the oil. If the color of the oil is deepened, the oxidation product is produced, the acid value is increased, and the sediment of the oil sludge is produced. Therefore, the determination of the acid value of the oil and the content of the precipitate can be used to determine the quality of the antioxidant stability of the oil. The larger the measured result is, the worse the antioxidant stability of oil products is.
Frequently asked questions about the oxidation stability of oil used in turbine oil:
1. can different types of steam turbines be mixed?
Due to the obvious difference in the additives of different manufacturers, mixed use is not recommended in general. If it must be mixed, the mixing test should be carried out in proportion, and the test items are mixed after being qualified.
2. turbine oil after being emulsified?
The emulsion may destroy the oil film when the water is discharged from the bearings. The emulsion can cause metal corrosion. The emulsion is deposited in the oil circulation system, resulting in insufficient oil supply. Oil is emulsified, which causes accelerated aging of oil products. Naphthenic acid soap and gum, which are produced by aging, further promote emulsification of oil products. The lubricating effect of the oil is reduced, the friction between the components is increased, the bearing is overheated, and the machine parts are damaged.
3. what is the difference between the performance of ammonia turbine oil and ordinary turbine oil?
Anti ammonia steam turbine oil is a device for sharing the same lubricating system with the compressor and steam turbine used in nitrogen, hydrogen and ammonia as the compression medium. The biggest difference from the ordinary turbo oil lies in the use of neutral or alkaline antirust agent to replace the T746 and other acid antirust agents used in the ordinary steam turbine oil to ensure that the oil does not react with the ammonia in the system. It is white floc, which affects the normal operation of the machine.
4. the advantages of gas turbine oil compared with ordinary turbine oil
As the gas turbine has the characteristics of energy saving and power, the lubricating oil is subjected to high heat surface, mixed with air (gas), pumping and circulating at a considerable rate, and being used under high pressure. Therefore, it is required that the gas wheel oil has better oxidation stability and abrasion resistance than the steam turbine oil.
