LIFE DETERMINATION DEVICE AND LIFE DETERMINATION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240200999 titled 'LIFE DETERMINATION DEVICE AND LIFE DETERMINATION METHOD
Simplified Explanation: The patent application describes an electronic control unit (ECU) that determines the lifespan of a pressure storage tank used for hydraulic oil. The ECU calculates the movement of a piston in the tank based on changes in the gas chamber's volume. When the total movement of the piston exceeds a set threshold, the ECU concludes that the tank has reached the end of its life.
- The ECU calculates the movement of the piston by monitoring the volume change in the gas chamber.
- The ECU sets a threshold value for the total movement of the piston to determine the end of the tank's life.
Key Features and Innovation:
- ECU monitors gas chamber volume changes to calculate piston movement.
- Threshold value set by ECU to determine end of tank life.
Potential Applications: This technology can be applied in various industries that use pressure storage tanks, such as manufacturing, automotive, and aerospace.
Problems Solved:
- Provides a method to accurately determine the lifespan of pressure storage tanks.
- Prevents potential failures by monitoring piston movement.
Benefits:
- Increases safety by preventing tank failures.
- Optimizes maintenance schedules by accurately predicting tank lifespan.
Commercial Applications: Potential commercial applications include manufacturing equipment, hydraulic systems in vehicles, and aircraft hydraulic systems.
Prior Art: Readers can explore prior art related to pressure storage tanks, hydraulic systems, and electronic control units in the field of fluid dynamics.
Frequently Updated Research: Stay informed about advancements in pressure storage tank technology, hydraulic system monitoring, and ECU innovations.
Questions about Pressure Storage Tank Lifespan Monitoring: 1. How does the ECU calculate the movement of the piston in the pressure storage tank? 2. What industries can benefit from the technology described in the patent application?
Original Abstract Submitted
an ecu is configured to determine the life of a pressure storage tank. the pressure storage tank has a gas chamber filled with gas, an oil chamber connected to a common passageway, and a piston dividing the gas chamber and the oil chamber. the pressure storage tank is configured to store hydraulic oil in the oil chamber and to release the hydraulic oil from the oil chamber. the ecu calculates a movement amount of the piston based on the volume change of the gas chamber. the ecu determines that the life of the pressure storage tank has ended when an integrated value of the calculated movement amount exceeds a threshold value.
