The introduction of rolling bearings of the burner

Burner is used to heat the bearing inner ring, make the bearing inner ring after heat expansion, is advantageous for the bearing from the shaft to be removed. In commonly used drawing, removing is difficult to use. Can be divided by use of fuel burner, gas burner kerosene and liquefied petroleum gas burner three, as shown in the figure below. Of fuel burner, when using, add fuel to no more than 3/4 of the barrel volume advisable ( Do not use kerosene and gasoline fuel) , which would hold some space to store compressed air, in order to maintain the necessary air pressure. Should be in the preheating combustion set in advance before ignition ( Cup) Pour a little gasoline, in a match lit, preheat flame nozzle. For flame nozzle heat, preheating combustion plate ( Cup) Pump up 3 - before in gasoline burn 5 times, unscrew the oil drain valve, the valve stem to open, the fuel of ejective mist shape, spray torch is lit the fire. Then continue to pump up, can be used to fire from yellow to blue. Should pay attention to air pressure is too high, after filling, cheer handle card should be firm on the pump cover. Attention should be paid to control the size of the flame, use environment should be no flammable items ( Solid, gas and dust) Cause fire, to prevent fuel leakage, temperature control heating parts and as required. In use process, should also pay attention to examine the fuel level in the tube, should be no less than a quarter of the cylinder volume. A major general might overheat the torch and unexpected accident. If need to put out a blowtorch, should first close the drain valve, when the flame extinguished completely, and then slowly refueling loose screw, tied to release the compressed air in simplified Chinese. Unscrew the adjustment switch, unscrew the hole cover again after cooling down.
