Solving Problems at the Rail Yard

Solving Problems at the Rail Yard

A Train Maintenance yard uses sand to gain grip on the track in inclement weather. They use large tanks to fill sand trucks to distribute the sand as necessary. The original system in this process used a pneumatically actuated butterfly valve to allow sand to fill the sand trucks from above out of a sand tank. They experienced issues with the actuator burning out on the valve shortly after installation.

IPT was called to inspect the existing system and found that the butterfly valve was unable to open due to the weight from the sand above, which stripped the actuator gears. Once the problem was found IPT installed a pneumatically actuated gate valve that slides open instead of turning. In addition to solving the actuator problem, IPT also made the system automated. Now the truck driver backs his truck under the covering and places the hose into his tank and hits a button. Once the sand reaches the top of the tank and touches our capacitance probe the sand valve shuts and the truck driver is free to pull away. The new system saves the drivers time and ensures the perfect amount of sand is delivered every time.
