| titleOfInvention | Oil bath heating method for local cooling |
| abstract | A heating method of oil bath with local temperature reduction is characterized in that the sealed oil bath is vacuumized, oil in a normal-temperature oil storage tank is filtered and then injected into three chambers of the sealed oil bath, an electric heating tube is started for heating, and heating is stopped when the temperature of the three chambers is more than or equal to 200 ℃; when the oil bath needs to be cooled, the electromagnetic stop valve at the oil outlet end of the middle cavity is opened, the oil flows into the high-temperature oil storage tank, the electromagnetic stop valve is closed, the electromagnetic stop valve at the oil inlet end of the middle cavity is opened, the oil pump is started again, oil in the normal-temperature oil storage tank is injected into the oil bath middle cavity, the electric heating tube is heated again, and meanwhile hot oil in the high-temperature oil storage tank flows into the normal-temperature oil storage tank after being cooled by the S-shaped cooling coil of the water; repeating the steps of heating, discharging hot oil from the middle cavity, injecting cold oil into the middle cavity and cooling and refluxing hot oil, so as to realize the local quick cooling and the integral quick heating of the oil bath; the method can rapidly heat and cool, and is especially suitable for automatic energy storage high-pressure liquid injection of CO 2 Phase change pulse coal rock mass fracturing device. |
