The combined ingenuity of six Electro-Mechanical Technology classes was on display this past semester as students demonstrated a mobile pumping station at McKenzie Pond on the Raymond Campus.
A motor control apparatus was connected to a generator-powered mobile power supply and hydraulics systems to make for a fully usable pumping system that moved water in and out of the pond, located next to McKenzie Arena along Seven Springs Road.
鈥淔luid power is basically the center of this whole project,鈥 said Garrett Hopkins, of Vicksburg, a student from the fluid power class. 鈥淲e have a diaphragm pump, centrifugal pump and our sump pump. The intake pump will pull the water into our reservoir. We have options with our sump and centrifugal pumps to pump the water back out into the lake.鈥
Switches and relays were connected to a boom lowered into the pond to move the water in and out. Power tools such as band saws and drill presses were used to create the project in just eight weeks by students in the PLC, motor control, fluid power, industrial control, power tools and troubleshooting classes.
The demonstration provided vital hands-on instruction to students learning to operate equipment used in the program, including the versatile PLC, or programmable logic controller, which can be used to write a code to automate the entire operation with minimal human manipulation.
鈥淭he idea was to show there are different types of pumps for different applications,鈥 said Jeffrey Hoovler, Industrial Maintenance instructor, who prompted his students to point out the function mimics what the average pumper-style fire truck does to move water from one source to another. It can also be used for agriculture purposes, to manage water used for cattle, for example.
A key lesson for students was to show how each mechanism involved had real-world applications.
鈥淚t showed all the different types of pumps, different uses for your pumps as well,鈥 said Alan Walker, of Vicksburg, a student in the industrial control class. 鈥淪o in case you don鈥檛 have an electrical supply but an air supply, you can run the diaphragm pump, which is run off air. It also showed how to wire your switches and relays.鈥
Pooling classes and knowledge in such a way promoted skills useful down the line in their eventual careers.
鈥淚 want to commend the students and instructors and the job they鈥檝e done,鈥 Vice President of Workforce & Community Development Chad Stocks told students. 鈥淲e鈥檙e watching what they learned go into practice. We鈥檙e sharing the labs, we鈥檙e sharing equipment and sharing the knowledge. We see from combining these classes they learn to work together.鈥
Some supplies used in the project, such as valves, switches and plugs, were funded through a Workforce Opportunity for Rural Communities (WORC) Initiative grant from the U.S. Department of Labor鈥檚 Employment and Training Administration in partnership with the Delta Regional Authority.
It also put the students鈥 classroom materials to work in a positive way, instructors said.
鈥淲e incorporated the textbook material and apply it to real life applications, while the students receive hands-on training in fabrication, troubleshooting, installation, and testing,鈥 said Frederick Jefferson, Industrial Maintenance instructor.

Students monitored the water level of the reservoir so once the float switch is activated, they can start the process of pumping water back into the pond using the centrifugal pump.

Students explain the operations of the generator, uses of the hydraulic actuator, and pneumatic air compressor to Vice President Sherry Franklin and Director of Workforce Solutions David Creel. These operations were taught in the Fluid Power courses at 蜜桃影像 Raymond Campus.
