Are you still feeding your vacuum pump to waste oil?

As we all know, oil-based vacuum pump is made of oil medium, if the use of substandard vacuum pump oil is like eating oil, the machine will soon be sick, then how should we choose the quality You are still feeding your vacuum pump to eat waste oil? Vacuum pump in the process, the vacuum equipment suppliers often require vacuum pump users to use the regular high-quality vacuum pump oil, and to regular oil change, the minimum requirements of customers Change the vacuum pump oil every three months. We have learned that there are not many domestic manufacturers engaged in vacuum pump oil production yet. Dongguan Road Vacuum Equipment Manufacturing Co., Ltd. is one of the most powerful vacuum pump equipment manufacturers. Dongguan Road Passes many years of practice concluded the following Point vacuum pump oil selection requirements and technical indicators. (1) require the vacuum pump oil at working temperature, pump oil must have a certain viscosity, and changes with temperature is small, in order to ensure a good seal. Viscosity is too small, the sealing performance is not good, the viscosity is too large, it will pump oil difficult to enter the rate of the surface of the gap, poor lubrication, while the rotor rotation difficulties, power consumption increases, pump oil will overheat. General requirements at 20 degrees when the saturated vapor pressure is not greater than 5.3 * 10-3 Pa; at 50 degrees the viscosity of the pump oil should be (47 ~ 57) * 10-6 m 2 / s range, which can meet the requirements. As the viscosity of the oil decreases with increasing temperature, the oil seal can deteriorate and the saturated vapor pressure increases, reducing the degree of vacuum. Therefore, the provisions of the vacuum pump oil temperature should not exceed 70 degrees. (2) vacuum pump oil vapor pressure is low, less volatile light fraction less. Because the ultimate vacuum of the pump depends mainly on the vapor pressure of the lightest fraction. The road through the VM100 vacuum pump oil saturated vapor pressure of 6.5 * 10-5 Pa at 20 degrees, suitable for all types of mechanical vacuum pumps. In addition to saturated vapor pressure, but also can be used pump oil ignition temperature (flash point) that, at this temperature, the accumulation of steam in the oil surface began to fire. Therefore, the higher the flash point of the pump oil, the less volatile lighter fractions, and the lower the saturated vapor pressure. (3) vacuum pump oil chemical stability, moisture, water-soluble acid. Less water-soluble alkali and other impurities. In the daily use of the vacuum pump, in order to reduce saponification of the pump oil during operation, a dryer may be installed at the pump inlet, which is filled with P2O5 or cold trap: built-in dry ice (solid CO2) to absorb Or freeze the moisture in the gas, the use of sulfur-containing oil in mechanical vacuum pumps; and avoid pumping of corrosive gases and solvents as they saponify the vacuum pump oil. In fact, the choice of high quality vacuum pump oil, it is better to choose a good vacuum equipment manufacturers, only the strength of the physical production plants have the professional production technology manufacturers to produce high quality vacuum pump oil. Dongguan Dalu Tong is an entity factory with vacuum equipment design, development, production and sale of after-sales service. Dongguan Dalu Tong has worked hard in the field of vacuum for 14 years and has accumulated a large number of professional and practical experience in the industry with high Evaluation, but also very much welcome to consult the relevant technical issues and exchange of industry information.
