Sales installation even into sewage pumps | centrifugal pumps connected to | repair and replacement parts | basic configuration sewage pump bearing replacement offer centrifugal pump is composed of eight parts, namely: impeller, pump, pump cover, retaining ring, pump shafts, bearings, seal rings, stuffing, axial force balancing device. 1 centrifugal impeller is the core part of its speed and high output force. 2, pump, also known as the pump casing, which is the main water pump. Fixed play a supporting role, and connected to the installation of the bearing bracket. 3, the role of the pump shaft is connected by means of coupling and motor, the torque of the motor is transferred to the impeller, so it is transmitting mechanical energy of 4 main components, seal rings, also known as Save the drain ring. 5, stuffing consists of filler, let the water flow out of the pump to not let the outside air into the pump. Always keep the vacuum pump inside! When the shaft and packing friction heat to rely on the seal pipe water to seal the filler cooling circle! 6, the axial force balance device, the centrifugal pump is running, because the liquid into the impeller is under low pressure, and flow out under pressure, ranging from pressure on both sides of the impeller, resulting in the entry point to the direction of the axial thrust, It causes axial movement of the rotor occur, resulting in wear and vibration, and therefore should be set axial thrust bearing to balance the axial force. One species, classified according to the number of the impeller 1, single-stage pump: that is the only one impeller shaft. 2, multi-stage pump: the pump shaft has two or more impellers, when the total lift of the pump impeller to lift the n and produced. Second, according to the working pressure Category 1, the low-pressure pump: pressure of less than 100 meters of water; 2, medium-pressure pump: pressure between 100 and 650 m water column; 3, high-pressure pump: pressure is higher than 650 meters of water. Third, according to Impeller method to classify a unilateral water pump: also known as single-suction pump, that only one impeller inlet; 2, bilateral water pump: also known as double suction pump, which impeller sides It has an inlet. Its flow is twice the single-priming pump, it can be approximated as two single suction pump impeller put together back to back. Fourth, according to the classification of a combination of the pump casing, horizontal split pumps: that is, in the horizontal plane through the axis opened a combined seam. 2, the vertical joint surface pump: the joint surface perpendicular to the shaft axis.
