DPY-3 type of crude oil processing performance electric tester using SCM control, with artificial fill pressure system that can simulate electric desalting and dehydration industrial sites, explore different treatment process crude oil. Instrument can display and print the temperature, pressure, electric voltage and time, test data, and has over pressure protection and overcurrent protection. Can be used above 100 ℃ heavy oil test. DPY-3 type of crude oil processing performance electric system pressure tester to meet the ultra-heavy oil desalting and dehydration of high temperature and pressure requirements. DPY-3 type of crude oil processing performance electric tester main technical indicators: electric voltage: 0 ~ 6000V continuously adjustable heating temperature: room temperature ~ 180 ℃ cooling method: rapid cooling water circulation, relief. Working pressure: ≤1mPa electrode types: Kennedy hanging, hanging two kinds of flat. Sample volume: 100 ~ 600ml
