Due to the compressibility of air and the nonlinear characteristics of pneumatic elements, pneumatic servo
control is much more difficult to achieve than electric or hydraulic ones [3,4].
Regardless of the type, the proportional valve is the most expensive component of the pneumatic servo
system, which diminishes the above-mentioned advantages of pneumatic drives [1, 2].
This pneumatic servo
dispensing system is a positive rod displacement metering system that combines the cost efficiency of a pneumatic drive motor with the controlling accuracy of a servo drive motor.
1 -- Sealant Equipment & Engineering has launched Pneumatic Servo
Dispensing (PSD) system, which is a positive rod displacement metering system combining the cost efficiency of a pneumatic drive motor with the controlling accuracy of a servo drive motor.
When using proportionally controlled pneumatic servo
valve, the error in torque is decreased to an amount of 1.
The company says the increasing industry adoption of pneumatic servo
valve technology was a driving factor in the development of the position-feedback option for the cylinder.
It features pneumatic servo
valves, electric servo-driven plugs, vertical preheat oven, and automated sheet-width adjustment.
An infinitely adjustable pneumatic servo
cylinder moves the stopper into the position required by the pouring program.
Most of the increase was from recently acquired businesses, notably: the Automotive Segment of Handy & Harman, a producer of automotive fuel-delivery system components; Long Manufacturing, a manufacturer of vehicle heat exchangers and air-conditioning evaporators; Nobel Plastiques, a European maker of fluid, hydraulic and pneumatic servo
control lines; Brosol, a Brazilian manufacturer of fuel system products; and, the North American Aftermarket division of ITT Automotive, a producer of brake parts sold under the brand name AIMCO.
systems play an important role and are widely used in modern industry (see pneumatic muscle systems [1,2], pneumatic brake systems , pneumatic manipulators [4,5], ball-plate pneumatic systems , etc.
The new actuator uses a specially designed pneumatic servo
drive system with few moving parts in order to further reduce the need for preventive maintenance of the actuator.
