Jedd Carlill South Hunsley School OCR Camebridge National In Engineering Design R106: Product Analysis and research Drill Pump 1:What is a drill powered pump used for? Drill pumps are useful for a variety of applications, including emptying clogs, changing oil, draining tanks, or pumping water out of pits or wells. Other related pump types include: mud pumps,-/ hydraulic pump, self-priming pump, transfer pump, dewatering pump. 2. Once the drill is turned on a small impeller within the pump begins spinning which draws the fluid through the intake and pushes it out through the outlet. Drill pumps are limited by the power of the drill and they can only handle small volumes of fluid Assignment scenario Many households experience problems with flooding due to burst pipes or extreme weather, simple pumps that can be powered by an electric drill widely available to help remove water from flooded areas however testing some of these pumps have shown they can fail to preform correctly You have been sked by a pump manufacturer to undertake product analysis of both its own and competitors pump products to establish the strength and weakness of the designs You will also consider the factors that influence the design of these pump products The product will be analysing initially is the silverline drill pump wich retails at £4.95 followed by a range of similar competitors products Commercial Product Methods One Off Production: Batch Production: •One product made at a time •Made for a specific need of a user or customer •High quality and can be used for prototypes •Made in batches of set quantity •Lower production cost and consistent quantity •If one product has an error, all in that batch will have to be recalled Mass Production: •Large amounts of standardised products •Used to make single components •Very efficient economically and very fast rate of production One Off Production Products: Injection Moulding 1. The mould closes 2. Injection the heated plastic is injected into the mould 3. The mould is left to cool 4. Ejection Disadvantages: high tool cost and long set up times, Advantages: low cost and a range of different plastics Step 1: the mold closes Step 2: the heated plastic is injected into the mold Step 3: the mold is given time to cool down Step 4: the mold gets ejected and its finished CNC Punching/Die Cutting 1.The die is placed onto your cutting material 2.The whole ensemble is pressed between two plates 3. The entire thing is then passed through your die-cutting machine sequentially cutting out the design Metal extrusion
