Abstract

The invention discloses a sound wave monitoring system of a pump and a method. The system comprises a sound wave sensor, a sound wave signal transmission cable and network, a sound wave data analysisplatform and a sound wave monitoring system platform; the sound wave sensor is installed on a monitored pump and used for collecting sound wave signals of the pump in real time and transmitting the collected sound wave signals of the pump to the sound wave data analysis platform and the sound wave monitoring system platform; a local sound insulation assembly is arranged outside the sound wave sensor; the sound wave data analysis platform is used for filtering and extracting characteristic parameters, and sending the characteristic parameters specially extracted from the filtered sound wave signals to the sound wave detection platform; and the sound wave monitoring system platform is used for analyzing the working state of the pump according to the sound wave signals of the pump, analyzingwhether leakage or internal leakage occurs or not or analyzing the corresponding relation between the sound wave signals of the pump and the rotating speed of the pump. By means of the relatively cheap sound wave sensor, real-time continuous online monitoring of the running state of the pump is achieved, the cost is low, the failure rate is low, and the detection rate is high.

Description

technical field [0001] The invention belongs to the technical field of pump monitoring, and in particular relates to a pump acoustic wave monitoring system and method. Background technique [0002] Pumps are widely used in production equipment in petrochemical, pharmaceutical, food and other industries, occupy an important position in the equipment, and are the power source of factory production logistics. In petroleum, petrochemical, and natural gas installations, the use of centrifugal pumps accounts for 70-80% of the total pumps. As a kind of fluid power equipment, the stable and safe operation of pumps is related to production safety and benefits, and there are more and more pumps in the market. The more relevant technology is to monitor the safe operation of pumps. [0003] With the development of the Internet of Things and sensing technology, remote online monitoring technology has been widely used in smart home, automobile and other industries, but it is relatively l...
