How much vacuum degree should be maintained for a vacuum oil filter machine when filtering?
As you know,vacuum degree is an important technical index for vacuum oil filter machine.Our company experiment many
times in this area for a long time.And summarize the requirement of vacuum degree for a vacuum oil filter machine when treat various kinds of oils.
1. Demand of vacuum degree when filtering insulating oils: the higher the better.
a. For single-stage vacuum oil filter machine,the vacuum degree should be kept above -0.095mpa.
b. For double-stage vacuum oil filter machine,its vacuum degree should be maintained between -5mpa ~ -50mpa.Since
this type of machine greatly improves its vacuum degree and pumping rate.It dewatering and degassing of transformer oils more faster and depth.Greatly increasing transformer oils` flash point and breakdown voltage,as well
as.
2. Suitable vacuum degree when filtering oils with high water content
When a vacuum oil filter machine filtering oils with high water content, the vacuum degree should be guaranteed
above -0.085mpa.However,the vacuum degree of machine will be reduced gradually due to heavy water content.If you found that the vacuum degree is decreased during working process,that means the oil vacuum pump should be checked
in time.If there is any emulsification, please change your vacuum pump as soon as possible.
