[0002] Hydraulic elevators have the advantages of smooth operation, comfort, low noise, and high utilization rate. They are widely used in villas in Europe and are also increasing in my country. They are widely used in public places such as subway stations, shopping malls, and parking lots. However, due to the influence of working conditions and environmental factors, hydraulic elevator failures also occur from time to time, especially hydraulic elevators produced by some small and medium-sized enterprises. Due to the use of some unstable hydraulic components, the failure rate is high. The hydraulic system of a hydraulic elevator not only plays the role of lubrication, cooling, rust prevention, shock absorption, and buffering of the mechanical parts of the elevator, but is also the main carrier of the elevator power. Therefore, the reliability of the hydraulic system determines the reliability of the hydraulic elevator. In addition, the elevator fault detection devices currently used are generally inconvenient to install, which makes it inconvenient for staff to use the detector. Utility Model Content
