PROJECTS

Pipette Controller

An Electro-mechanical device to quickly fill and release accurate volume of chemicals into pipette

• Complete design and detailing of the product to accommodate pump, trim, tubing, battery, pcb and lcd display. Drafts, sink marks and undercuts are taken into consideration while designing plastic components.

• New trim designed which helps to pump air into and out of the system using one positive displacement pump

• 3d printed prototypes to check its functioning and usability before going into mass manufacturing using plastic injection molding

Kettle fryer - potato chip line

Conventional fryer is included with a stirrer mechanism to produce kettle fried style potato chips of capacity 500 Kg per hr

• Specification of potato chips at the outfeed end is 1.5% Moisture, 35% oil pickup, bulk density 50 gm/liter to 70 gm/liter. Frying time is approximately 3 minutes.

• Screw stirrer mixes the oil to achieve the thermal equilibrium of the system and also moves potato chips to the outfeed end. It was so designed not to topple over during motion along the fryer bed.

• Sizing of shaft, chain drive, power, heat load according to modification of the capacity of the fryer

• Added rollers at the bottom of the fryer structure to eliminate thermal stresses due to thermal expansion of the Fryer at 180 deg celcius

• Multiple oil entry and exit points into the fryer to transfer heat to food product efficiently

• Fabrication drawings of equipment made of sheet metal and tubes with welding details and weldment cutlist.

FEA - lifting mechanism

An object weighing 100 Kg needs to be lifted up and rotated in angular position using using ball screw

• Static analysis is performed on critical components. Fixtures and remote loads are applied to simulate real world conditions.

• Von Mises stress plots were studied to determine the most stressed regions. Mesh refinement was done on areas of interest which reduced computer resource and hence faster results were achieved

• The arm is modified to include two square tube extrusions instead of one. Two radial and thrust bearings were used at the pivot. Thickness of the extrusion and bolt size was modified according to design requirements.

• Guide shaft displacements were kept minimal for smoother operation of ball screw

• Optimized the design with minimal material. Hence reduced the weight of the assembly.

• Calculation to determine Power and Torque requirement for geared motor Water Column with probes

A cylindrical column which detects the liquid level in the boiler by using probes installed in it at various positions which in turn drives the thermal load to the boiler

• Calculations to determine the probe location in the water column attached to the boiler incorporating density level error

Liquid Level Gages

Liquid level gauge is used to see the level of the liquid in a pressure vessel. These gauges are used as a single unit or stacked up in multiple sections to view a desired height of liquid in a vessel or tank.

• Designed according to ASME BPVC section VIII div 1

• Developed spreadsheet design calculations to determine the factor of safety of pressure vessel component parts of liquid level gages including glass and magnetic gages. Calculated the deflection of flanges and verified with the allowable deformation for leakage criteria according to asme codes and standards. 3

5300 Automatic Recirculation Control Valve

This product is used to protect centrifugal pumps while the flow is not enough in the system.

• Designed the valve according to ASME standards B 31.3, B 16.5 and B 16.34

• I have worked on the project with a team of engineers. Team members are required to upload drawings for sand casting and machining components into a vault with "draft in progress" status. I have to check and approve the drawings and change the status of drawings to "released". While checking if any mistakes were found, they will be tabulated with numbering. So team members can go to the table and recheck their drawings before uploading into the vault. Hence reduction of errors while creating the drawings. Variant Configurator, CPQ (Configure, Price and Quote) VC, CPQ is used to generate sales order quotes, BOM for all allowed configurations. It will connect sales, engineering and production

• Code creation for all the options available under all family of valves to be used in Model String for all allowed configurations. 2 digit codes for mandatory and 3 digit codes for non mandatory for all options.

• Contacting manufacturing plants to understand any other rules not mentioned in catalogs and incorporating those rules between option classes in a tabular form like “Yes”, “No”, “Sometimes”.

• The rule table for allowed combinations of options will be created for the Schema OR Product matrix. Non standard selection will automatically goes to ETO

• ETO will be enabled for unallowed configurations. Engineering has to create special parts which are not available in the system

• Superbom/PPC is created to pick the component parts in BOM according to the options selected by user

• Routing and pricing information is added into separate files. These files help to generate quotes and scheduled delivery dates for the particular configuration.

• Parts and Bom creation using material master MM01, CS01 Parametric Modeling - Access Covers using ilogic

Assembly, parts and drawings will update according to the user form. Variations can be generated easily in less time using the ilogic template’s

• Created an ilogic template for assembly, parts and drawings.

• Dynamic user form created using VBA to update the parameters according to user defined values.

• Complex rules were built which include VBA code. It will update beam and cover depth depending upon the load class. Even or odd no of cover’s can be designed. Routing - Piping

Reverse Osmosis (RO) Nano Filtration (NF) systems

• Skid design for capacity 500 gpm

• Optimized the system by performing structural analysis

• Creation of Piping and Instrumentation Diagram (P&ID) Composite - Boat

Watercraft with two parallel hulls.

• 55 feet Ship - Flybridge, Sunbed.

• Marine standard - Rina, Enave.

• Plug design - Mold lamination

• Lamination schedule table - gel coat, hand layup and vacuum infusion details with CSM, quadriaxial, biaxial, uniaxial laminate.

• Resin transfer molding (RTM) process for access covers.

• Strengthening the parts with core material at stressed areas.

• Surface development - Deck flooring, Fabric, Core
