DRILLNG FLUID TESTING INSTRUMENT 1. Summary The Electrical Stability Tester is a kind of instrument used mainly to measure the relative stability of water in oil (w/o) emulsion.In addition, the electrical resistance caused by impurity present in electrolytic solution and the stability to time can be predicted from the measurements of the relative emulsion stability. This instrument also can be used to evaluate the oil base drilling fluids, oil base releasing stuck agent, cement and crack water etc. Therefore, it can be extensively applied in petroleum, metallurgy, drilling crew and research...

DRILLNG FLUID TESTING INSTRUMENT 1. Switch of power supply; (2) Working principles The instrument adopts the advanced technology of frequency conversion. It alters the AC220V±5%, 50Hz to AC220V, 340Hz. The voltage output of 0~2000V, 340Hz can be realized by virtue of regulating using the 340Hz voltage regulator and increasing voltage using the transformer of intermediate frequency. When regulating voltage, the material tested between electrodes is ionized slowly and finally broken down. At this time, the feedback loop is working and the instrument starts alarming. The instrument is replaced...

DRILLNG FLUID TESTING INSTRUMENT Prevent the transformer of high voltage is burnt out due to short-circuit current. (9) After the tests are completed, press the key of “STOP” on the frequency meter. The displayed “340.0” will stop altering about three seconds later. At this time, turn off the main switch and then take off the plug of power supply (10) Take off the electrode, and then wash and dry disposal for the use next time. 6. The maintenance of the instrument (1) The environment of usage for the instrument should be kept dry and neat. (2) The operator should be familiar with all the...
