Continental AG Preliminary Cooling System Design

Colton Knight - William Klein - Zachary Dobias

Preliminary Task Requirements

• The cooling system will be

designed to supply an automated machining line as part of the new plant.

• The design is created to handle the

coolant from the time it reaches the plant until the dirty coolant is removed from the premises.

Selection of Materials

• In the selection of the tanks and pipes

stainless steel was chosen given the corrosive properties of the coolant.

• A coating was not needed around the

material due to the minimal corrosive properties of the fluid and to minimize initial expenses.

• All calculations for both the piping

systems and tanks have been performed to ensure the materials selected can handle the pressures the system may be subjected to.

Example of Materials Subsystem 2

Storage Tank Design and Layout

• The Clean Storage Tank has a volume of

16000 gallons and is located on the top of the roof near the train tracks. ○ This will allow for all delivered coolant to be taken from the train.

• The Dirty Storage Tank has a Volume of

10000 gal and is located outside of the building on the ground.

• The Reservoir tank is located inside the

manufacturing facility next to the machining area.

• The size and wall thickness of each tank

have been selected and proven adequate through the design calculations.

Maintenance Considerations

• Given the necessity to perform maintenance on the cooling system. The time required to

fill and empty the largest storage tank can be done within a single shift.

• With the flow rates and times to fill and empty the tanks chosen this allows for more than

enough time to complete any necessary repairs to the cooling system from wear over time.

Pipe Size and Layout

• The clean storage tank has been

elevated to the roof of the facility in

• rder to eliminate the need for an

extra pump. The overall layout of the system was designed around this concept.

• The pipe size, thickness, and layout are

based on a series of calculations based

• n the desired flow rate between each

system.

• The routing of the pipes and locations
• f the tanks allow for complete

accessibility through the driveway to the facility.

Structural Support Design

• Structure is a major safety component

with any design. The number of hangers and distance between them are designed to support the load from the weight of the pipes and forces from the flow of fluid.

• The pipes will be supported with

standard clevis hangers.

• The calculations for the weight and

windload on the storage tanks have been completed to assist in the development of tank supports by working alongside the civil engineers.

Valves and Fittings

• The valves and fittings in the system

were selected to control the flow rate

• f the fluid and prepare the system in

case of failure.

• The utilization of standard 90 degree

elbows ensures the initial expense of the cooling system is minimized.

• Through the use of gate valves the risk
• f experiencing a problem in fluid flow

such as a water hammer is greatly

• reduced. This ensure that anyone
• perating the valve will not close it too

quickly.

Emergency Blind Flange & Open Channel

• The Open Channel is designed to

insure that there is a safe and effective way to remove the coolant away from the manufacturing plant in an emergency event that requires the entire system to be drained.

Table: Summary of Open Channel Width of Channel, b (ft) Wetted Perimeter, WP (ft) Hydraulic Radius, R (ft) Open Channel 0.3953 0.7908 0.0988

Utilizing Gravity

• By placing the clean storage tank on

the roof of the facility, no pump is required as gravity does all the work. This will allow for the reservoir to be filled with 1000 gallons by simply

• pening a valve.
• By not using a pump in this subsystem

the initial expense of the new cooling system will be reduced.

Pump Requirements

• The requirements for the performance
• f the pump were calculated before

the selection of the pump began.

• By laying out the necessary pump

characteristics, the selection of the pump type can be proven to require a Kinetic Radial Pump for both pump driven systems.

• In order to assist the electrical

engineers, the required power output

• f the electrical motors have been

determined according to the pump requirements.

Pump Selection

• Given the requirements of the pumps per each subsystem of the design, the actual pumps

can be selected using the graphs provided by Sulzer.

• The specific pumps and impeller size have been chosen based on the required pump head

and flow rate of each subsystem.

• The efficiency of the pumps has been determined to allow for the calculation of the Net

Pump Suction Head and proven the pumps selected are capable of meeting the requirements of each subsystem.

Summary of Preliminary Design

• In the design of the new cooling

system, the main priority was to create the most efficient layout of the tanks and pipes to minimize complications in maintenance and future problems.

• This design serves as a preliminary

layout of the new cooling system to be refined and adjusted as needed to ensure all necessary criteria have been met.
