Gear Pumps in Modern Industry
Gear pumps do more than simply move hydraulic or chemical fluids. In today’s industry, the demand for specialized equipment has given birth to businesses that provide this equipment to the aerospace and aircraft industry, as well as to many other areas of industry. Today’s industry has special demand for fuel-delivery systems, and here is a look at some common types of pumps and applications that see a great deal of use in modern industry.
Military Turbo Jet
The military uses UAV turbojet-powered air vehicles for many important missions. UAV stands for Unmanned Aerial Vehicle, and they see a lot of usage for reconnaissance missions and attack missions. These types of vehicles can be used in situations that would place a great deal of danger on human lives.
The turbojet engines are simple in design, and permit a wide variety of fuels. The fuel system requires a special pump that is precision metered for proper fuel flow. It is also uses a specially designed pump for cooling and lubrication. These pumping parts are designed by Cascon, which specializes in gear and gerotor pump applications for industry.
Tactical Air Launch Decoy Applications
The Tactical Air Launch Decoy or TALD sees use for saturating and confusing enemy air defense systems. They are often used to allow attacking aerial weapons to penetrate enemy air defenses, and thus increase the odds for success. They saw a great deal of success in the early 1990s, in Operation Desert Storm. These devices use a turbojet engine, and can fly at altitudes of 30K feet, reaching speeds close to Mach I.
This motor requires a precision made, variable-flow pump for the fuel system. It is made to integrate with the digital power supply control logic, and the output varies from 20 to 400 pph. It contains a brushless direct current motor, which provides the signal to the tachometer. The pump assembly is made from stainless steel and contains special Samarian cobalt brushes within.
Microturbine Generators
Microturbine generators are a relatively new source of clean energy on the market today. They have few moving parts and produce clean emissions. They are used for hybrid electric cars, as well as for large applications. In industrial applications, a specially-designed fuel pump is required.
These systems need a pump that can provide fuel at a fifty to one turndown ratio. The system also requires very accurate feedback and fuel monitoring, and this is provided by a Hall Effect switch. Wetted components are sealed hermetically from the windings and the control parts. This prevents problems with fluid leakage that may occur with these systems. The gear pump is precision engineered, and designed to withstand the high demands that can be placed upon it.
Summary
In today’s industry, there is a special demand for gear pumps that can deliver fuel to engines. Military UAV planes have turbojet engines with special needs and conditions. Tactical air launch decoy vehicles and microturbine generators require fuel systems with specific components and needs. It takes a great deal of skill and experience to design and produce these components, and companies such as Cascon are supplying important needs to industry.
