(Summary description)Edward vacuum pump oil's role is increasingly prominent, and it can better maintain the normal operation of Edward vacuum pump. With its use of equipment, it can reduce wear, reduce temperature, prevent leakage and many other faults during operation, making the use of the pump more efficient. Smoother and longer life. Manufacturers of vacuum equipment generally have their own designated oil, which is based on different types of pumps used in different industries to choose the appropriate vacuum pump oil. In this environment, its products can reach various information indexes, otherwise the quality and reputation of vacuum equipment will be affected by changing the inappropriate vacuum pump oil. What are the ways to choose a good Edward vacuum pump?

1. Very low vapor pressure: This is an important performance indicator of vacuum pump oil. The lower the vapor pressure, the higher the vacuum degree. Since the rotary vane vacuum pump rejects the vacuum degree exceeding 0.06Pa, and the high rejection exceeds 1.33×10-4Pa, the cooling property of rejecting the vacuum pump oil is extremely low. Generally, paraffin-based narrow-cut lubricating oil is used. For spreading vacuum pump, it can also be used for silicone oil or other synthetic oil with very low vapor pressure.
2. Appropriate viscosity and good viscosity-temperature characteristics: The vacuum system uses the constant change of the internal volume of the pump chamber to form exhaust, and the rejected lubricating oil should have suitable viscosity and good viscosity-temperature characteristics.
3. Better thermal oxidation stability: The vacuum pump is constantly developing towards high speed. Due to the high-speed friction between the sliding vane and the pump body, the oil temperature rises, so the heat and oxidation of the oil are intensified. The spread pump is often working at a high ambient temperature, and the thermal oxidation difference will make the vacuum pump oil hydrolyzed and deteriorated. As a result, the vacuum degree is low, so it is rejected that the vacuum pump oil has better thermal oxidation stability.
4. Good anti-corrosion and anti-emulsification: If the corrosive gas discharged from the vacuum pump will rust, the metal parts and the oil in the pump will undergo chemical changes again. In addition, the water vapor in the exhaust air often causes the emulsification of the vacuum pump oil, so it refuses to have better corrosion resistance and anti-emulsification. The emulsification of vacuum pump oil used in the vacuum hydrolysis process is more noticeable.
5. Lower flash point: It is forbidden to load light components in the vacuum pump, so as not to affect the saturated vapor pressure of the oil.
