    Bolt heaters can be divided into two forms: electric heating and electromagnetic induction heating.    The electromagnetic induction heater adopts a DSP+IGBT structure, which can quickly heat bolts and achieve the purpose of disassembling and assembling bolts. The electromagnetic induction heater heats M140 * 938 bolts for about 2 minutes, which is about 20 minutes faster than ordinary bolt heaters, improving the efficiency of maintenance work.    The rated power of the bolt heater can meet the simultaneous use of 6 or 12 output circuits, with sufficient redundant capacity. The bolt heating rod is customized according to the bolt size. The bolt heating rod is made of 316 stainless steel and equipped with a temperature sensing probe to transmit the bolt temperature in real time to the bolt heating electric control cabinet. Each output circuit of the bolt heater is equipped with a separate temperature display and power adjustment function, which can achieve automatic heating function. Satisfy on-site disassembly and assembly of low-pressure and high-pressure cylinder bolts, and improve the efficiency of disassembly and assembly work.

    The exciter shaft neck sway measurement bracket is used to support the exciter rotor during the exciter shaft neck sway measurement process, and is a special tool for exciter maintenance.

Product Features    According to the maintenance process requirements of nuclear power plants, after the connection between the exciter generator coupling is completed, it is necessary to remove the exciter rotor support bearing shells, use support rings or lifting ropes to support the rotor, and measure the circumferential runout of the shaft neck. The measurement time for the vibration of the exciter shaft neck is relatively long and the work needs to be continuous without interruption. The use of temporary support for the rotor by the crane and lifting rope will cause the crane to be occupied for a long time, affecting maintenance efficiency. Therefore, we have specially designed and manufactured the measurement dedicated bracket.    The gate bracket is fixed on the split surface of the exciter bearing seat, and the rotor journal is supported by bearing shells. There is a gearbox adjustment mechanism on the upper part of the bracket, which can adjust the position of the bearing shells up, down, left and right to ensure that the bearing shells support the rotor, and then adjust the rotor position to the state when the bearing shells support it.
