Abstract

The invention discloses a detection system and method for fluid leakage of a canned motor pump. Capacitive sensors are respectively installed on the two sides of a stator coil in a canned motor pump.A temperature sensor is installed on each side of the capacitive sensors. An air pressure sensor is installed in the shielding cavity of the canned motor pump. The system and the method have the advantages of simple structure, low price, high sensitivity, good dynamic response characteristic, strong adaptability to bad conditions such as high temperature, radiation and strong vibration, and the like.

Description

technical field [0001] The invention relates to a detection system and method, in particular to a detection system and method for the leakage of a canned pump used to transport toxic, inflammable and explosive liquids. Background technique [0002] With the development of China's economy, the transportation of various highly toxic, flammable and explosive liquids is very large, so it is very necessary to prevent accidents. In the mechanical industry, for the monitoring system with stable performance and toxicity of various liquids, its detection accuracy, timeliness, reasonable design, and rapid alarm are in line with relevant national regulations, and this field is very important. [0003] At present, highly toxic substance production plants have been established in many regions of China, and a large number of people live around them. In the past ten years, the field of highly toxic chemicals has been greatly developed, and various testing institutions are currently testin...
