Title: Mark M Qandil: Innovator in Motor Systems
Introduction
Mark M Qandil is a notable inventor based in Camas, WA (US). He has made significant contributions to the field of motor systems, holding a total of 4 patents. His innovative designs focus on enhancing the efficiency and functionality of electric motors, particularly in submerged applications.
Latest Patents
One of Qandil's latest patents is the Immersible Motor System. This system utilizes a totally enclosed fan-cooled (TEFC) electric motor to provide power. The motor enclosure is designed to be sealed with various sealing devices, including a double mechanical seal, a single mechanical seal, a double lip seal injected with grease, a labyrinth seal, and/or a repeller positioned adjacent to the motor enclosure. A release mechanism is incorporated to prevent the fan from creating excessive drag when the system is immersed in water. The fan cools the motor when the water level is below the motor, and the surrounding water aids in cooling when the water level rises. The release mechanism can take the form of a shear key, a torque-release clutch, or flexible fan blades. Alternatively, a separate fan motor may be provided for driving the cooling fan.
Another significant patent is the Dry-Pit Submersible Pump, which also employs a TEFC electric motor. Similar to the Immersible Motor System, this pump features a release mechanism that prevents excessive drag when submerged. The fan cools the motor when the water level is below it, and the surrounding water assists in cooling when the motor is partially submerged. The design ensures that the fan does not impose a load on the motor due to the surrounding water.
