In the practical application of the vacuum pump, sometimes encounter a variety of vacuum pump oil-related issues, such as: ①Known a common purpose import pump model, wondering if the original factory oil grade may be what? ② Known import pump Oil grades, phase understanding of its viscosity grade. ③ known import pump oil viscosity grade, how to choose the trial of domestic oil products, and then be identified in order to ensure the pump performance and operational reliability, as well as lower and reasonable costs. ④ For the users and distributors of Shanghai Vacuum Pump Factory, sometimes they need to know the standard, viscosity, quality grade, refueling quantity and recommendation of our factory specific products and the current factory oil, as the same time ordering the spare oil grades Number of references. So, etc., for this purpose, specially collected some information and practical experience for the relevant users and production, distribution, maintenance personnel reference. Vacuum pump oil selection considerations Because the price of imported vacuum pump oil is much higher than the domestic oil, so if you can correctly choose to replace the domestic oil, will significantly reduce the cost of use. For domestically produced pumps, if the vacuum pump oil can be reasonably selected, it will have a good effect on the pump partial pressure limit, ultimate pressure, start, power consumption, pump temperature, pump performance stability, anti-emulsification performance and reliability . For the vacuum pump manufacturer, the selection of high quality vacuum pump oil, can improve the overall performance of the pump, to bring benefits to most users, have good social benefits. For the user, if the effect of the factory oil is not very satisfactory, but also depending on the circumstances of choice. For example: ①If the weather is cold, start difficult, optional low viscosity oil pump. ② If the pump for a long time at higher pump temperatures, such as the pump in the summer heat and the environment have poor ventilation, the inlet gas is heated or the inlet pressure is higher, etc., the choice of a high viscosity grade oil or may apply High temperature, high load pump oil, such as HFV-A series of oil. ③ If the pump temperature is high, and the pressure on the pump is less than the full pressure requirements, such as the two-stage pump limit the total pressure ≤ 5 Pa, can elect to replace the viscosity of 100 or 150 qualified oil, or the same or slightly higher viscosity of the mechanical oil, Oil, mechanical oil prices lower. ④ If the oil change period is shorter or shorter, but also to meet the performance requirements, you can change with the viscosity or slightly higher viscosity of qualified oil or mechanical oil, compressor oil, in order to reduce the cost of oil change. The specific choice by the user to decide.
