Detection calibration device of coolant pump rotating speed monitoring system and detection calibration method of detection calibration device

Abstract

The invention discloses a detection calibration device of a coolant pump rotating speed monitoring system. The detection calibration device comprises a case, a rack arranged in the case, a motor driving module, a motor, a revolution meter, a control panel, a protection cover, a mounting bracket, a message sending tooth mounted on an output shaft of the motor, a sensor mounted on the mounting bracket, an amplifier connected with the sensor through a coaxial cable, and an oscilloscope and a coolant pump rotating speed monitoring system data processing unit that are in communication connection with a signal output end of the amplifier, wherein the motor driving module, the motor, the revolution meter, the control panel, the protection cover and the mounting bracket are mounted on the rack; the motor driving module is connected with the motor, the revolution meter and the control panel through wires; the control panel is connected with a power supply, the motor driving module and the revolution meter through wires; and during operation, the message sending tooth is driven by the output shaft of the motor to pass through the sensor. The device solves the problem that a special detectioncalibration device for the coolant pump monitoring system and a detection calibration method are unavailable at present.

Description

【Technical field】 [0001] The invention relates to the technical field of calibration of a rotational speed monitoring system, in particular to a detection and calibration device and a detection and calibration method for a power plant coolant pump rotational speed monitoring system. 【Background technique】 [0002] The coolant pump is one of the key equipment of the power plant during the operation of the entire power plant, and it is also the only rotating mechanical equipment in the cooling system. This equipment has been in a state of unmanned monitoring on site for a long time, so the speed monitoring system is required for remote monitoring of the equipment (monitoring equipment includes generators) Fast tooth, magnetoresistive sensor, connecting cable, signal processing unit, DCS), and currently there is no detection (calibration) device and detection (calibration) method specifically for this monitoring system in the market, so our company has developed a detection (cal...
