How to use infrared thermometer correctly
Introduction: Infrared thermometer temperature measurement principle is the object (such as steel) emitted infrared radiation has the radiation energy into an electrical signal, the size of infrared radiation energy and the object (such as steel) itself corresponds to the temperature, according to the size of the electrical signal converted into the size of the object (such as steel) can be determined the temperature of the object (such as steel).
In the use of infrared thermometer, it is correct in judgement!
In the past, generally follow the mixture of liquid "overflow point" to smash the cement floor to find "leakage point", often twice the effort. Shengli Oilfield Ludong three mining centre technicians use infrared thermometer sensitive to the temperature characteristics, to achieve a fast and accurate to find the pipeline leakage point.
General polymer injection well pipeline to the wellhead is a mixture of polymer mother liquor and sewage, the temperature of about 40 ℃. The mixture coming out from the puncture leakage point is transported along the largest underground porosity, and can be transferred for more than 10 metres at the longest, and finally overflows from the weakest point, i.e. the spillage point. Mixed liquid transfer process temperature gradually decreased, that is, the lowest temperature of the spillage point, and the highest temperature of the puncture leakage point.
Therefore, the actual search for leaks, as long as the handheld infrared thermometer from the spillage point along the path of increasing temperature to find the highest temperature point that is to find the leakage point. Multiple leakage tests have proved that this method saves time and effort, accuracy of 100%, and can greatly reduce the scope of smashing the concrete floor. This year, the infrared thermometer was used to find leaks in 15 wells, shortening the pipeline processing time by 6 hours per well on average, and increasing the amount of polymer solution injected by 680 cubic metres.
In addition, the infrared thermometer can also be used to monitor the station control cabinets, switchboards and other places with strong currents, and accurately and timely find out the abnormalities such as false connection and loosening at the AC contactor junction points, which is simple and quick to operate and does not affect the normal operation of the equipment.
