Application Story

Spray Foam Machines

A manufacturer of spray polyurethane foam (SPF) equipment developed an automated, high-accuracy system for void-filling applications like taxidermy molds and boat hulls. The system uses a proportional pump to deliver chemicals from two drums to a spray gun, producing polyurethane foam. To maintain consistent, high-quality foam based on user-defined recipes, the manufacturer required a precise method for metering the chemical output.

Application

A manufacturer of professional spray polyurethane foam (SPF) equipment offers an automated, high-accuracy system for void-filling projects such as taxidermy molds, boat hulls, walls, and impact insulation for shipping containers. Its configuration includes a proportional pump, which transports chemicals from two multi-gallon drums to the nozzle of a spray gun to create polyurethane foam.

The automated SPF machine follows user-defined batching recipes to balance precise ratios of chemicals from each drum to create a stable, consistent foam. To ensure quality foam production as defined by user parameters, the manufacturer needed a precise method of metering the exact output of these chemicals.

Challenge

A precise amount of chemicals must flow through the hose of the automated SPF machine to ensure exact amounts are dispensed that match recipes entered by an operator. The pump is not reliable enough by itself as its stroke may drift over time, resulting in systematic compromises to dispense precise amounts of chemicals. A consistent, accurate, metering method not prone to drift, overspin, or media slippage under pulsation is essential to determine and maintain the preset mix as determined by the end user.

Products Supplied

JVM-30BBV-NS Positive Displacement Gear Flow Meters. By ensuring the correct proportional output of the expensive chemicals in this process, this positive displacement gear flow meter prevents overdosing and reduces material costs.

Solution

AW-Lake Positive Displacement Gear Meters provide ultra-precise chemical batching for the SPF machine over time. After a recipe is entered into the controller (or DCS), the pump activates, causing media to flow through the flow meters. As the media is metered, the flowmeters produce a signal that is sent back to the DCS, which controls the pump. When dispensed media meets specifications for producing the amount of foam to a preset batch, the DCS turns off the pump. This, in turn, halts foam production. Integrated sensors report when setpoints are reached to ensure precise batches of chemicals enter the hoses, guarding against under- or overdosing chemicals and allowing exact amounts of polyurethane to be sprayed by the machine. To ensure longevity and chemical compatibility, the meter features a ball bearing design that works well in non-lubricating media, such as the chemicals used here.
