This application belongs to the field of compressor technology, specifically relating to a method for identifying valve faults in reciprocating compressors. As a crucial component of reciprocating compressors, valves have a relatively high failure rate, especially in ultra-high pressure reciprocating compressors, where valve failures are even more prominent. Existing fault diagnosis methods are mostly limited to process parameters and sound analysis, which are complex and require a high level of professional experience from testing personnel, thus limiting their widespread application in engineering practice. This application provides a method for detecting valve faults in reciprocating compressors. It obtains the temperature of the valve cover on the same side of the cylinder and processes the data based on its distribution and trend characteristics. Evaluation indicators are constructed using the similarity of the temperatures of each valve cover, and valve faults are identified using the characteristic distribution patterns of normal valve temperature data. This provides an easily applicable reference method for early and rapid identification of valve faults in reciprocating compressors.

The application relates to the technical field of engineering design simulation, and provides a power battery box cover pressing test simulation method, device, equipment and medium, the method comprises the following steps: acquiring frame design parameters and cover design parameters of a power battery box; generating a power battery box simulation frame according to the frame design parameters; generating a power battery box simulation cover by simulating cover stamping on a preset flat plate cover material according to the cover design parameters; assembling the power battery box simulation frame and the power battery box simulation cover to obtain a power battery box simulation model; and performing pressing simulation on the power battery box simulation model according to preset pressing parameters to obtain a pressing simulation result. The method can quickly predict whether the battery pack has a pressing rebound abnormal sound problem before the battery pack is produced and manufactured, has high analysis precision for the abnormal sound problem of the battery pack, and can reduce the abnormal sound analysis cost.

A toilet monitoring system and device for detecting toilet operating conditions through acoustic analysis are provided herein. The system includes a sensor unit configured to be mounted on a toilet bowl and a control unit coupled to the sensor unit. The control unit captures and analyzes sounds from toilet operation to identify operating conditions by comparing captured sounds to reference sound patterns. When operating conditions are detected, the control unit generates alert signals. The sensor unit enables monitoring through external mounting, while the control unit's sound analysis capabilities allow differentiation between various conditions like clogs and leaks. The system can be installed without permanent toilet modification and provides condition detection through acoustic pattern recognition.
