Abstract

Rolls-Royce produces various engines which must be tested prior to their distribution to ensure a high-quality product. The manufacturing plant contains four test cells where the engines can be subjected to high levels of torque and extreme temperatures. A heat exchanger is necessary in this testing system and over time, unwanted waste accumulates on the system’s plates. The team is tasked with developing and implementing a system mounted on a mobile cart which can provide data to determine whether the plates need to be cleaned. For this cleaning system to work, it must fully saturate the heat exchanger in cleaning solution, making the choice of pump important to the planning process. Additionally, the pump must be able to handle liquid containing silt and other debris and possess a maximum flow rate allowing the plates to be saturated. The pump must have four connection points to the heat exchanger system, and the fitting nozzle to control the flow rate of the cleaning solution into the heat exchanger. The cleaning solution for the system must be strong enough to clean the waste from the heat exchanger, yet weak enough to not corrode the plates. Additionally, some cleaning solutions have standards regarding storage and disposal, which have considerable influence on the selection of an acceptable solution. The final design incorporates a workable pump, a suitable solution, and the supporting materials needed to sustain the system. Implementation of the design will include pressure testing and a cleaning system that will improve the life span and efficiency of the heat exchanger in each test cell.
