The invention relates to a rotating equipment phase angle measuring device. The device comprises a photoelectric sensor, a signal receiving device, a counting device and a marking disc, wherein the marking disc is used for being arranged on a rotating shaft or a shaft coupling of a rotor of the rotating equipment; 72 light reflecting belts are adhered to the same radius of the marking disc at equal intervals, and the angle of each equal division of the light reflecting belts is 5 degrees, so that the shaft necks of the rotating shaft or the shaft coupling of the rotor are uniformly divided into 72 equal divisions; and the photoelectric sensor is connected with the signal receiving device, the signal receiving device is connected with the counting device and used for enabling signals sent by the photoelectric sensor to irradiate the reflecting belts and then return signals when the rotor is rotated, the number of the returned signals is recorded by the counting device, and the rotatingangle of the rotor is calculated by multiplying the number of the signals by 5. The rotating equipment phase angle measuring device of the invention can determine the mounting position of the balanceweight through the rotating of the rotor on the premise of not uncovering a bearing box, thereby saving the workload and the working hours and having accurate measurement.
Description
technical field [0001] The invention belongs to the technical field of dynamic balance of rotating equipment, and in particular relates to a phase angle measuring device of rotating equipment. Background technique [0002] The rotating part of the rotating equipment, that is, the rotor, inevitably produces unbalanced mass in the process of casting and processing. When the rotor rotates at high speed, it will generate severe vibration, which will affect the safety of the equipment. In order to eliminate this adverse effect, the rotor needs to be dynamically balanced. The key to dynamic balance is to determine the circumferential position of the counterweight installation. At present, to determine the circumferential installation position of the counterweight in the process of dynamic balancing of the rotor, it is necessary to remove the bearing box and measure the phase angle. This measurement method has large errors, heavy workload, and long time consumption. Contents of t...
