Centrifugal pump structure description

The main structure of the centrifugal pump from the impeller, pump body, pump shaft, bearings, seal ring, stuffing box six parts, for its six part structure, we understand? If you do not understand, now Xiaobian Centrifugal pump one by one on the structure. Centrifugal pump structure Description 1, the impeller is the core part of the centrifugal pump, it is higher than the speed of large impeller blades play a major role in impeller before the assembly through the 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 2/3 to 3/4 of the volume too much will heat, too few have a sound and heat! Sliding bearings are used as a 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! During the pump running 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 gap between the pump housing and the pump shaft so that the water inside 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. The above is the structural component of the centrifugal pump, I hope the above content to deepen our understanding of the centrifugal pump.

We are a manufacturer of automatic door openers that are designed to provide people convenience. Automatic Door Systems` drive to provide that level of service is but one of the reasons why automatic doors are becoming more and more popular. Our Automatic Sliding Door systems are modern, space-saving and elegant. Automatic sliding doors have many basic functions some of which include: automatic mode with full opening width and/or reduced opening width, and exit only for traffic control. The opening of automatic doors can also be adjustable to make the opening width smaller or larger. Important safety functions such as safety sensors prevent the door from shutting if persons or objects are in the detection zone. If the door leaves are inhibited when closing, they are immediately re-opened or if the door leaves are hindered when opening, they are immediately stopped by a safety automatic reversing mechanism.
