DEVICE FOR MEASURING A SEAL GAP OF A LIQUID OXYGEN PUMP, ENABLING A PLURALITY OF BOLTS TO BE UNIFORMLY FASTENED BY MEASURING THE GAP BETWEEN EACH POINT ON THE FRONT OF THE SEAL OF THE LIQUID OXYGEN PUMP
DEVICE FOR MEASURING A SEAL GAP OF A LIQUID OXYGEN PUMP, ENABLING A PLURALITY OF BOLTS TO BE UNIFORMLY FASTENED BY MEASURING THE GAP BETWEEN EACH POINT ON THE FRONT OF THE SEAL OF THE LIQUID OXYGEN PUMP
PURPOSE: A device for measuring a seal gap of a liquid oxygen pump is provided to prevent seal failure due to lack of uniformity of bolt fastening and prevent the leakage of liquid oxygen due to seal failure.;CONSTITUTION: A device for measuring a seal gap of a liquid oxygen pump comprises a base member(10), a bar member(20), a gap measuring unit(30) and a bolt unit(20b). The base member is arranged across the center of the rotating shaft of a pump. The bar member is mounted on the base member and the end of the bar member is connected to the rotating shaft of the pump. The gap measuring unit is installed on the base member, makes contact with the front of the seal of the pump and measures distance. A shaft connecting bolt, which is fastened to an impeller locking groove on the rotating shaft of the pump, is formed on the end of the bar member. The bolt unit is fastened through the base member. A nut unit(20c) is fastened to the bolt unit.;COPYRIGHT KIPO 2011
