Better Control of the Welding Process

Application
Machine for automated production of blood bags

Colpitt has traditionally used pneumatic or hydro-pneumatic cylinders to control the movements of their blood bag welding machines. However, they were not able to control the process as precisely as this application required. Colpitt was looking to switch to an electric servo system which could control all the motion for this process through PLC programming providing better control of the welding process.

GSX40 and GSX50 servo actuators were used in this application offering Colpitt the ability to manipulate motion parameters instantaneously, via an operator interface panel, eliminating the need for setting switches or changing offsets. This allowed Colpitt to achieve a quick transfer motion combined with a controlled low speed move for pressing at the end of each move. Not only did this help Colpitt maintain a high cycle rate, it also allowed them to achieve the accurate pressing control that their application requires. The integrated nature of the GSX servo actuator allows both force and speed to be set very precisely resulting in an accurate and easily controlled process.

Gas Turbine Electric Valve Actuators

Industrial gas turbine packages must deliver efficient and dependable performance with low operating and maintenance costs in order compete in today’s global market place.

Challenge
Industrial gas turbine packages must deliver efficient and dependable performance with low operating and maintenance costs in order compete in today’s global market place. In order to accomplish this goal, manufacturers and retrofitters are turning to all electric servo solutions for their actuator needs, eliminating the need for pumps and tubing normally associated with hydro- mechanical or pneumatic designs. Exlar Corporation is a worldwide leader in the design and manufacture of industrial electric servo actuators.

Application Solution
Fuel Control Valve:  The use of electric actuated fuel control valves on gas turbines can replace pressure regulator/gas loaders, throttle valves, and associated electrohydraulic actuators. Exlar’s servo electric actuators integrate a high performance servo motor and a specially designed roller screw mechanism for converting electric motor power into linear motion. The roller screw, which consists of multiple threaded helical rollers assembled in a planetary arrangement around a threaded shaft, is capable of carrying heavy loads for thousands of hours even in very arduous conditions. This, combined with high torque servo motor technology, provides a compact and powerful linear actuator solution for fuel valves.

Benefit
Each Exlar actuator, when supplied with Exlar’s all digital positioner, will respond to command signal changes in less than 5 mSec. The speed of the response combined with the dynamic capability of the all-electric actuator delivers repeatability much greater than typical pneumatic or hydraulic cylinders and allows for end-to-end travel time of a 6 inch stroke actuator of less than 200 mSec. This performance makes Exlar’s actuators the obvious choice for applications such as turbine controls.

Exlar’s FT Series Actuator for Coal Diverter Gate

Exlar’s FT Series Actuator Performs in Class II Hazardous Location Environment

Application:
Coal Diverter Gate /Damper Control

Drawing of Exlar’s FT60 actuator installed on the
coal diverter gate.

The Challenge
The customer was using an Andco hydraulic actuator to control their coal diverter gate. Due to the actuator’s age, the customer was experiencing difficulties sourcing replacement parts for the unit. The Andco actuator also utilized old technology that the customer wanted to update through the purchase of a new actuator solution. This application required an actuator with a long stroke length that could control the motion of their large coal diverter gate. This application also required a solution that was rated for Class II hazardous locations because of the presence of coal dust in the facility.

Application Solution
The customer had previous experience with Exlar on a turbine application and felt comfortable with the Exlar product. They worked with the local Exlar representative and decided to purchase two FT60 actuators. The actuators provided the necessary stroke length for this challenging application; one actuator with a 12 inch stroke and the other with a 24 inch stroke. Operating in a Class II environment was required for this actuator solution and Exlar’s FT60 combined with a Explosion Proof motor and a Grove gear reducer satisfied this requirement. The customer also required a special trunnion mount and motor support bracket for their application which Exlar willingly designed. This non-standard trunnion mount and custom motor support was easily incorporated on to the FT60 actuator because of Exlar’s immense experience designing and manufacturing custom made actuator solutions for their customers.

Servo Electric Turbine Valve Actuator

Replacing the hydraulics actuators with  all electric servo actuators in older steam turbines.

Challenge
There are hundreds of steam turbines installed throughout the military and process industry that incorporate pre-1970 design. The valves on these turbines are predominantly operated by hydraulic actuators. Maintaining these hydraulic systems is costly with spare parts becoming more and more difficult to find. The control on these turbines in many cases is no longer adequate in today’s marketplace. Many plants that have older steam turbines are now upgrading them with digital controls and replacing the hydraulic actuators with all electric servo actuators from Exlar.

Application Solutions
Steam Control Valve Steam turbines incorporate two basic arrangements of control valves: Shell Mounted and Chest Mounted. Shell mounted control valves are attached to the turbine shell. Some are modulated by a rack and cam arrangement. This valve operating method utilizes a common hydraulic cylinder to lift a rack of four to nine poppet valves in sequence. A fulcrum lever is used to multiply actuator force. Exlar directly replaces this main hydraulic actuator with a high performance servo electric actuator and positioner.

Benefit
Each Exlar actuator, when supplied with Exlar’s all-digital positioner, will respond to command signal changes in less than 5 mSec. The speed of the response combined with the dynamic capability of the all-electric actuator delivers repeatability much greater than typical pneumatic or hydraulic cylinders and allows for end-to-end travel time of a typical 6 inch stroke actuator of less than 200 mSec. This performance makes Exlar’s actuators the obvious choice for applications such as turbine controls.

Injection Molding

For generations, hydraulic cylinders were the core pull devices selected by mold makers. But today, when it comes to creating the core pull actuation, the ideal electro-mechanical solution is provided by Exlar.

Challenge
Most plastic parts have a void. That void houses the electronics of a lap top computer or cell phone; on a plastic plate that void creates separate places for baked beans and potato salad. But, cycle time is where the money gets made. After the molded product is competed, the mold still has to be cycled, the core removed, the product ejected; and how fast those actions can be moved in and out impacts production.

Application Solution
Traditional hydraulic cylinders are fast, but Exlar’s GSX actuator can enhance cycle rates by letting related operations get started sooner. Exlar’s actuators and associated servo amplifiers can monitor their own position as well as the status of the rest of the machine, and allow processes to begin as early as possible, and work in conjunction with other processes to maximize throughput. Traditional limit switch controlled hydraulics don’t offer this flexibility.

This an Exlar Application Solution.
