Troubleshooting Paper Machine Problems Through Thermal Imaging

Plastic welding can join thermoplastic parts together. Several methods of plastic welding are available. Proper techniques are critical.

Paul Maier, project manager of the NYSERDA study, states that "Pump sandblasting and coating should be a required step of any pump. refurbishment program." MCWA has also included interior pump coatings as a requirement in its new pump specifications. The goal is that. requiring coatings on the inside of. new pumps will eliminate, or significantly delay, the seemingly inevitable decline in pump performance and efficiency from internal corrosion and tuberculation buildup inside unlined pumps.

Too much heat can cause multiple problems with cartridge mechanical seals. Some heat problems are not seal design or seal installation related.
