Briefly describes the structure of the centrifugal pump 5)

the basic construction of centrifugal pump is composed of six parts, respectively is: impeller, pump body, pump shaft, bearing, seal ring, stuffing box. , is the core part of a centrifugal pump impeller, its high speed output power is big, on the impeller blades and play a major role, the impeller through static balancing experiments before assembly. Impeller on the inside and outside for smooth surface to reduce friction loss of water. , pump body also calls the pump shell, which is the main body of the pump. Support fixed effect, and connected to install bearing bracket. , the role of pump shaft is connected by coupling and motor, the torque of the motor to the impeller, so it is a major part of the mechanical energy transfer. , bearing is set on the pump shaft support, pump shaft components, which has two kinds of rolling bearing and sliding bearing. Rolling bearings must be properly use butter as a lubricant oil is commonly / ~ / size too much will be fever, too little and there was a noise and fever! , sealing ring, also known as minus leakage ring. Import and pump impeller shell gap between in the cause of high water in the pump by means of this clearance flow to the low pressure area, affect the water yield of pump, efficiency! Clearance starts to cause the impeller and pump casing friction wear. In order to increase the flow resistance reducing internal leakage and delay the service life of the impeller and the pump shell, the pump casing and impeller around the foreign aid junction with sealing ring, sealing gaps remain. ~。 It is advisable to mm. And stuffing box is mainly composed of filler, seal ring, packing, packing gland, water tubes. The role of the stuffing box is mainly in order to close the gap between pump casing and pump shaft, don't let the flow within the pump does not flow outside to not let outside air into the pump. Always keeping the vacuum inside the pump! When the pump shaft and be about to rely on water seal packing friction heat to hold water to the water seal circle packing cooling! Keep the pump running. So in the process of pump run Tours of inspection to check the stuffing box is paying special attention to! In running an hour or so of packing replacement.
