Gap adjusting tool for lower flange of hydrogen cooler of generator

A clearance adjusting tool for a lower flange of a generator hydrogen cooler comprises a magnetic attraction tool, a sensor and at least one distance adjuster. And the sensor is fixed on the magnetic suction tool and is used for measuring the gap between the lower flange of the generator and the hydrogen cooler. And the magnetic suction tool is detachably fixed on the lower flange close to the generator end cover body or detachably fixed on the generator end cover body. The distance adjuster is located on the gap between the end cover body and the lower flange and used for adjusting the gap between the lower flange and the hydrogen cooler. And one end of the distance regulator is contacted with the lower flange while the other end is contacted with the end cover body. According to the measurement information of the sensor, an operator can adjust the gap more accurately in real time through the distance adjuster, repeated adjustment is not needed, the efficiency of gap adjustment is greatly improved, the speci
