The winter in the north is cold. In the oil field, once the screw pump production equipment is stopped, the driving head of oil emulsification is very easy to freeze. In order to solve this long-standing problem, the members of Song Jianji Skills Master Studio of Fuyu Oil Production Plant of Jilin Oilfield developed a set of "screw pump driving head fast defrosting device", which not only avoids the potential risks in the traditional defrosting process, but also greatly reduces the cost of understanding the freezing. "There are more than 1100 screw pump wells in Fuyu Oil Production Plant, and freezing of screw pump drive head caused by oil emulsification often occurs in winter. The traditional treatment method is to defrost the drive head with a high-temperature vehicle. During operation, high-temperature steam is sprayed to the drive head, and the frozen oil is melted through heat transfer. During the cleaning process, the water falls to the ground and freezes into an ice slope, which forms a great safety hazard." Song Jianli said, facing the problem that plagues the enterprise, The young people in the studio could not sit still and tried to find a better solution. For this matter, the studio member Lin Jiaqi did not spend less time. One day, her car door was frozen. She found a way to defrost the car door by covering the towel with a hair dryer on the Internet, and it worked. Inspired by this, she repeatedly studied and tested and found that although the hot-air gun can thaw, it takes a long time and affects the production time rate. "Can we turn the hot air into a heating device that directly acts on the driving head?" Lin Jiaqi, after many experiments and analysis, finally developed a set of fast defrosting device that uses silica gel electric heating plate to heat and independently adjust the defrosting temperature through the temperature controller. It can adjust the heating temperature randomly within the range of 0-90 degrees Celsius, with fast heating and high thermal efficiency, and can realize fast defrosting of the frozen screw pump driving head. Song Jianli made a calculation for the reporter: "Before, it took about 600 yuan to use the high-temperature vehicle to defrost once, and only 5-10 kilowatt-hour electricity was needed to use this device, and the electricity cost was 10 yuan and 20 yuan. The processing cost of this device was about 500 yuan, and the cost of application came back. In addition, this device is safe and durable, easy to operate, and can be used repeatedly."
