How to select the vacuum pump oil -

in the practical application of vacuum pump, sometimes will meet all kinds of problems related to the oil. For example, 1. Is general import pump type. I want to know how much is the original engine oil level. 2. Known level of imported oil pump, know their level of viscosity. 3. Understand the import pump oil viscosity grade, how to choose the domestic oil products for trial, and then determine to ensure the performance of the water pump and operation reliability, low and reasonable cost. 4. For users and distributors of Shanghai vacuum pump factory, sometimes they need to know our specific product and the current plant oil standard, viscosity, quality grade, the fuel quantity and recommendations. The quantity and number of references. For this purpose, therefore, have to relevant users as well as the production, distribution and maintenance personnel to collect and compile some materials and practical experience.

due to import vacuum pump oil is much higher than the price of oil, therefore, if you can correct choice can replace the oil, the cost will be greatly reduced.

for domestic pump, if it is reasonable to select the vacuum pump oil, will limit the partial pressure of pump, limit the impact pressure, starting, power consumption, temperature of the pump, pump performance stability, good impact demulsification performance and reliability.

for vacuum pump manufacturers, the use of high quality oil products can improve the overall performance of the pump, bring benefits for most users, and produce good social benefits. For users, if you use the effect of plant oil is not very satisfactory, also can choose according to the specific situation. For example, 1. If the day is cold, it is hard to start. You can choose low viscosity grade of oil pump. 2. If the water pump work long time under high temperature of pump, for example, if you have any heat pump in summer and poorly ventilated environment, the suction gas is heated or high inlet pressure. Can choose or application has a viscosity grade of oil quality. Suitable for high temperature, high load of pump oil, for example HFV - A series of oil. 3. If the high temperature of pump and pump pressure is not high, the double pump pressure maximum 5 or less Pa, for example, you can choose qualified engine oil viscosity for 100 or 150, or the same or slightly higher viscosity machine oil, compressor oil, machine oil prices lower. 4. If the oil change period is short or short, and it can meet the performance requirements, you can choose the same or slightly higher viscosity oil qualified or machine oil or compressor oil, in order to reduce the cost of an oil change. The specific choice is determined by the user.
