Some suitable kinematic viscosity bath liquids
Methyl alcoholThis is quite volatile, has a low flash point, and has a degree of toxicity. Ethyl alcohol is also volatile and has a low flash point, but unless iingested is relatively non-toxic. Some halogen-based fluids are marketed as low temperature bath fluids, but these also have a high volatility, ...

How to choose a suitable kinematic viscosity bath liquid
In order to accurately measure kinematic viscosity in glass capillary viscometers, the viscometers must be suspended in a constant temperature bath. The ideal bath fluid would possess low viscosity, high heat capacity, and low vapor pressure over a wide range of temperatures. In addition, the liquid ...

Recovery rate of waste oil recycling machine
During process of waste oil recycling, the machine removes more than 95% harmful substances and nearly does not affect original base oil(including its additives), therefore the stability, oxidation resistance and anti-emulsification etc. of oil are better than normal base oil. The following table is ...

Working principle of waste oil recycling machine
The waste oil recycling machine initially removes impurities and water(Vacuum dehydration process, dehydration heating temperature is about 60℃– 80℃); then, vacuum flash vaporization on heated oil(Distillation heating temperature is about 230℃–300℃. Heating temperature is not the same due ...

General Knowledge of Insulation Oil
The main functions of electrical insulation oil are cooling and insulating, also eliminating electric arc when switch off. Because of system leakage, poor sealing, oil in heat-load state for a long time and open storage etc., the water and gas enter into oil which resulting in oil having water gand gas. ...

Preliminary judging criteria for transformer oil dissolved gas analysis
1. Nitrogen and around 5% oxygen: Transformer operates normally. 2. Nitrogen and over 5% oxygen: Check tightness of transformer. 3. Nitrogen, carbon monoxide and carbon dioxide: Transformer overload or cellulose is damaged by heat during operation. Operation condition should be checked. 4. Nitrogen and ...
