Fluorine plastic centrifugal pump mainly by the impeller, pump body, pump shaft, bearings, seal ring, stuffing box six parts, then we all know what part of the pump? If you do not know, the following is about Fluoroplastic centrifugal pump structure description. Fluoroplastic centrifugal pump structure Description 1, the impeller is the core part of the fluorine plastic centrifugal pump, it is high speed high output force, the impeller blades play a major role in impeller assembly before static balance experiment. The inner and outer surfaces of the impeller require smoothness to reduce the frictional loss of water flow. 2, also known as the pump casing, it is the main pump. To support the role of fixed, and with the bearing bracket to connect. 3, the role of the pump shaft is connected by a coupling and motor, the motor torque to the impeller, so it is the main component of mechanical energy transfer. 4, the bearing is set on the pump shaft supporting the pump shaft components, there are two types of rolling bearings and plain bearings. Rolling bearing the use of butter as a lubricant to the appropriate general size of 2/3 ~ 3/4 Too much heat, too few have a sound and heat! Sliding bearing centrifugal pump structure is the use of transparent oil lubricants, refueling To the oil level line. Too much oil to bleed along the pump shaft and bleach *, too little bearing overheating and burned to cause an accident! In the process of running the pump bearing temperature up to 85 degrees generally run at 60 degrees, if high, we must find the reason (Whether impurities, whether the black oil, whether water) and timely treatment! 5, seal ring, also known as leakage ring. The gap between the impeller inlet and the pump casing is too large, causing the water in the high-pressure area of ​​the pump to flow to the low-pressure area through the gap, affecting the water output of the pump and reducing the efficiency. If the clearance is too small, friction between the impeller and the pump casing will be caused to wear. In order to increase the backflow resistance to reduce internal leakage, delay the service life of the impeller and the pump housing, the inner edge of the pump housing and the impeller is provided with a sealing ring at the joint of the outer support, and the sealed clearance is maintained at between 0.25 and 1.10mm. 6, stuffing box mainly by the filler, water seal ring, packing tube, packing gland, water seal tube. The purpose of the stuffing box is to close the empty space between the pump housing and the pump shaft so that the water in the pump does not flow outside and the outside air does not enter the pump. Always keep the vacuum inside the pump! When the pump shaft friction with the filler to generate heat will depend on the water seal to live in the water seal to make the packing cool! Keep the normal operation of the pump. Therefore, during the inspection of the pump running inspection of the stuffing box is of special note! The filler should be replaced after about 600 hours of operation.
