摘要： Le chauffe-eau à protection cathodique élimine le besoin d'avoir recours à une tige conventionnelle en guise d'anode. Le réservoirchauffe-eau comprend une enceinte cylindrique (2) fermée par des têtes supérieure et inférieure (3,4), et un brûleur à gaz (6) est placé sous la tête inférieure. Les produits de déchets de la combustion sont déchargés vers le haut au travers du réservoir via un tube d'évacuation de fumée qui est monté dans des ouvertures ménagées dans les têtes inférieure supérieure. La surface externe du tube d'évacuation ainsi que la surface supérieure de la tête inférieure sont revêtues d'un métal anodique (12) à l'acier, et le revêtement métallique sur le tube d'évacuation s'étend de manière continue depuis la tête inférieure jusqu'à un point situé au-dessus de la tête supérieure. La surface interne de l'enceinte et la tête supérieure sont revêtues d'un revêtement résistant à la corrosion telle que du verre ou un métal anodique à l'acier également, et le bord supérieur de la bride (14) dans la tête supérieure bordant l'ouverture est soudé directement au travers du revêtement métallique au tube d'évacuation tandis que la périphérie externe de la tête inférieure est soudée au bord intérieur de l'enceinte. Lorsqu'un métal anodique à l'acier est appliqué sur la surface intérieure de la tête supérieure et de l'enceinte, il est appliqué sur une épaisseur suffisante au moins au niveau de la jonction de l'extrémité inférieure de la bride périphérique de la tête supérieure et de l'enceinte pour boucher et sceller le creux qui existe généralement entre l'extrémité libre de la bride de la tête supérieure et la paroi de l'enceinte. Le revêtement métallique sur la tête supérieure/le creux de l'enceinte scelle hydrauliquement la soudure extérieure entre la tête supérieure et l'enceinte par rapport à l'eau contenue dans le chauffe-eau et forme une barrière à la corrosion et une surface anodique vis-à-vis de l'eau contenue dans le chauffe-eau. Lorsqu'il existe des soudures dans le revêtement métallique au niveau

摘要： The outlet fitting (5) of the hot water tank is connected to a pipe (7) by way of a nipple (6) including an internal damper (8). This is constituted by a sleeve (9) having sector-shaped flaps (10) integrally hinged to it by hinge portions (11). In a no flow standby condition, the flaps (10) extend transversely across the sleeve (9) to close off the fitting (5) and prevent hot water heat loss by convection. During periods of water flow, the flaps are pivoted to a dotted line open position to permit water flow through the fitting with minimum restriction.

摘要： A gas water heater includes a water tank, a combustion chamber, a burner, a heat exchanger tube at least partially within the water tank, and a fan. The burner receives fuel gas and primary air to create a primary air-fuel mixture for combustion in the combustion chamber with secondary air. The primary air-fuel mixture has a gas concentration above the upper explosive limit of the fuel gas. Secondary air is supplied to the combustion chamber through a secondary air conduit that is separate from the burner. The heat exchanger tube receives the products of combustion, transfers heat from the products of combustion to water in the tank, and exhausts of the products of combustion. Only air flows through the fan; no fuel-air mixture flows through the fan. The water heater utilizes partial premix combustion with low excess air ratio and low contaminant emission. The water heater utilizes a high power burner such that the water heater can supply hot water continuously during low flow rate draws and hot water stored in the tank supplements the hot water supply of the water heater during higher flow rate draws.

摘要： A pumping apparatus for a jetted-fluid system includes a pump having an inlet connectable to the drain, and an outlet connectable to the return. The pump is adapted to receive the fluid from the drain and jet fluid through the return. The apparatus includes a motor coupled to the pump to operate the pump, a sensor configured to generate a signal having a relation to a parameter of the motor, and a switch coupled to the motor and configured to control at least a characteristic of the motor. The apparatus also includes a microcontroller coupled to the sensor and the switch. The microcontroller includes a model observer configured to receive a first value based on the signal and to generate a second value representative of at least one of a modeled flow or a modeled pressure based on the first value. The microcontroller is configured to control the motor based on the second value.

摘要： Permanent magnet rotor with several skewed sections, which are axially arranged. This rotor can be inserted into different stators of different lengths for different output power. The angular skew depends on phase number and stator pole number. Concentrated winding on each stator tooth or every second tooth. The tooth faces have dummy channels (recesses) to further reduce cogging. The dummy channels have trapezoidal or round shape.
