地面油罐和半地下油罐内的油温和环境温度总是有一定的温差,特别是在炎热的夏天,半地下油罐的油温要比大气温度低10℃左右。如果在测量油温时温度计使用不当,就很难测准罐内油料的平均温度,使计算出来的油料重量不准确。如某油库去年6月份测量一个3000m~3半地下油罐的油温时,由于对温度计没有采取一定的措施,连续换了几个人测量,所得结果均不相同,计算出来的油料重量相差3t多。其原因是由于油温与气温相差太大,温度计从油中拿出来在大气中停留时间的长短影响了温度计读数的准确性。目前多数油库使用温度计,都是用一根钓
There is always a certain temperature difference between the oil temperature and the ambient temperature in the surface oil tank and the semi-underground oil tank, especially in the hot summer, the oil temperature in the semi-underground tank is about 10 ° C lower than the atmospheric temperature. If the thermometer is not used properly when measuring the oil temperature, it is difficult to measure the average temperature of the oil in the tank, making the calculated oil weight inaccurate. Such as a depot in June last year, measuring a 3000m ~ 3 underground tank oil temperature, because the thermometer did not take certain measures for a few people for a continuous measurement, the results are not the same, the calculated weight difference of more than 3t oil . The reason is because the temperature difference between the oil and the temperature is too large, the thermometer out of the oil in the atmosphere to stay the length of time affect the accuracy of thermometer readings. At present, most oil depots use thermometers, all with a fishing tackle
