Guangdong imported vacuum pump used in oil products _ constant mechanical and electrical equipment co. , LTD

import vacuum pumps as a kind of basic extraction device, are widely used in various industries, many types of it, either in life or in the process of production, vacuum pump users around the world have a passion for the field, including plastic machinery, chemical pesticides, dyes, chemical industry, brick machinery, cryogenic equipment, paper making machinery, pharmaceutical and chemical industry, food machinery, industrial furnace, electronic industry, vacuum equipment, petrochemical industry, metallurgy, mining and foundation treatment, etc. , due to its simple and compact structure, therefore, is not sensitive to dust and water vapor in the air, so it plays an important role in the petroleum products. Small make up by this article lead you to understand the import vacuum pump application in petroleum products.

what is the oil? Mineral oil is flammable liquid, in the initial stage by the Chinese working people find and use. Color is mainly black, brown or dark green, occasionally is yellow. Usually, the oil is lighter than water. Most oil density of 0. 77 to 0. 96 g/cm3。 Oil is a complex mixture of hydrocarbons. In the composition of oil, carbon content is 84 - For about 12-85%, hydrogen content 14%, and there is a small amount of containing sulfur, oxygen and nitrogen organic compounds. In addition, in the oil was found in a small amount of iron, nickel, copper, lead, vanadium, arsenic, magnesium, phosphorus, potassium, silicon, calcium, manganese and other elements.

petroleum products usually refers to the various products obtained from refinery processing.

import vacuum water pump structure characteristics, mainly include the following:

1, in a wider range of pressure pumping speed greatly.

2, rotor with good geometrical symmetry, small vibration, stable running. Between the rotor and have clearance between rotor and shell, no lubrication, friction loss is small, can greatly reduce the driving power, which can realize high speed;

3, vacuum pump cavity without sealing and lubrication oil, can reduce pollution of oil steam vacuum system;

4, vacuum pump cavity no compression, no exhaust valve. Simple and compact structure, is not sensitive to be smoke dust and water vapor in the gas;

5, compression is low;

6, rotor surface for cylindrical shape more complex curve.

import vacuum pump application in the oil products

1. Dry gas oil

if the gas oil products contain very small amounts of water, it will make the color opacity and not bright, thus greatly reduces the business the price of the product. However, if the gas from the distillation unit and through only 37-112 MMHG vacuum drying tower, basically can remove the trace moisture contained in the gas oil, crystallization and crystallization product.

2。 Furfural extraction lubricant

in order to remove the colloid substances contained in the lubricating oil, get cycloparaffin polycyclic short side chain, aromatic hydrocarbon, ingredients, such as sulphide or nitride by senior lubricating oil. Is essential for refining processing. Liquid - Furfural extraction and purification of typical solvent refining technique of production rate from 80% to 90%. The boiling point of furfural for 161. 7 t, when the temperature higher than 230 ° C happens when the stack.

3。 Solvent dewaxing oil products

in petroleum products, kerosene, diesel oil and light oil contains more paraffin wax, and in heavy oil and residual oil, the wax content is higher, sometimes content as high as 25% or more. As a result, some performance and liquidity. In addition, paraffin wax and wax is an important industrial raw material, so we must to dewaxing oil products.
