Brushless DC Motor Ceramic Submersible Pump (Brushless fuel pump) Introduction Electric control fuel injection (injection technology) is the auto industry in recent years in a major advanced technology, which allows air and fuel mixture than better and more uniform fine mist more, burning more secure, thus reducing the automobile exhaust The amount of pollution, improve engine power and save fuel. However injection system currently used in high-pressure pumps, are using a brush DC motor driven pump (gear pump or roller pumps). With brush in the rotation when the motor commutator brush in the surface-to the frequent friction and heat, the higher the speed, the higher surface temperature, then commutator radial and adjacent deformation of the inter � The abrasion is higher , the spark in great level , because of the sparks, easily ignited fuel, not security. Coupled with the fuel pump is immersed in gasoline ( add a fuel ethanol or methanol), then with the sulfur in gasoline, methanol or ethanol will be corrosion commutator, so that the DC life will be decrease. As brush and commutator friction in the process of sulfur in gasoline like cauterant, such as corrosion, will have a lot of black mealy solid, it will make the gasoline and Circuit serious pollution, discourage fuel from pathway, wall up the nozzle, Fuel combustion engine is not in full, exhaust emissions were relatively high, and couldn�t achieve purposes of environmental protection. Also the current fuel pump used the body materials were aluminum or cast iron materials, they immersed in the fuel with the worm gear ( gear or roller) between the relative friction, abrasion and corrosion will also in pump The shortening of life. At present the life of the fuel pump about 2, 000 -3000 hours. This technology provides a brushless DC motor from the body composition of the ceramics named brushless DC motor ceramic submersible pumps, the existing technology to solve a brush DC motor submersible pump the existence of the structure is irrational, insecure, intolerant Corrosion, and a shorter life expectancy, exhaust emissions were relatively high, and other technical problems. Specific solutions are as follows: There will replace brush DC motor to brushless DC motor and the body will replace the ceramic body. As Brushless DC motor directly from the electronic circuit for the control, no change spark, So the fuel used in more secure. Because the electronic circuits was anti-corrosion, the motor life will be longer. In the absence of brush and commutator friction, so there is no fuel and Circuit pollution, more fuel combustion, exhaust emissions from waste less, more conducive to environmental protection, while fuel consumption will go down, save fuel. As brushless DC motor high efficiency, less current, the great flow of the pumps, and increase of engine power and torque, improved engine performance. Also due to the use of ceramic materials for the body, wear-resistant and corrosion-resistant ceramic materials, the pump also greatly extend the life. As a result of this technology above actions, its integrated life will be extended to 20, 000 hours. The project has received utility model patents by national, patent No.: ZL200620095548.X. The project will be the implementation of China&＃039;s automobile industry to a new level of play a great role for China&＃039;s export of electromechanical products to make greater contributions to global environmental protection cause of contribute. So its revolutionary technological innovation will bring about tremendous social and economic benefits.
