This is an overview of the motion of the "standard" type of diesel fuel pump cam which is used to deliver fuel from the fuel tank to the combustion chamber of a single-acting, tubular type of diesel hammer. What are Kinematics? As defined in Seely and Ensign, "Kinematics deals with the relation between distance, time, … Continue reading The Kinematics of Diesel Fuel Pump Cams
Much of the narrative around Vulcan centres on the development of the Warrington-Vulcan pile hammer design in the late 1880's (and the serial number records aren't the most informative about when exactly the final transition to that design was made.) But how did Vulcan come up with the valve design it made its standard? Some … Continue reading Some Insight into the Origin of Vulcan’s Pile Hammer Valve System
When Vulcan introduced the Vari-Cycle in the late 1960's, it thought that the issue of stroke changing during operation had been solved. But there were exceptions Both the #1 and #0 series hammers had difficulties with physically accommodating the Vari-Cycle, and when the 5' stroke hammers were introduced in these size ranges there were durability … Continue reading Traverse Trip
A common problem in elementary statics is picking up a load with a sling. It's an important one in heavy lifting, and Vulcan certainly experienced a great deal of that. We're going to look at an example: the Internal Pile Hammer IPH-16. It's shown with its skid on the truck above; we're going to look … Continue reading An Example of Balancing a Sling Picked-Up Load: the IPH-16
