Vertical pump impeller under the disk called what? What role?
The stuffing box is mainly composed of packing, water seal ring, stuffing box, packing gland and water seal pipe. The function of the stuffing box is mainly to close the gap between the pump shell and the pump shaft. The water in the pump is not allowed to flow outside and the outside air is not allowed to enter the pump. Always keep the vacuum in the pump. When the pump shaft and the packing friction produce heat, it will depend on the water seal to keep the water in the water seal ring, so that the packing can cool down and keep the pump running normally. Therefore, in the water pump running inspection process, the stuffing box inspection is particularly necessary to note that in the operation of 600 hours or so, it is necessary to replace the filler.
The disc under the vertical pump impeller is the pump body, which affects the water output of the pump. Play a supporting role in the fixed role!
Bearings are mounted on the pump shaft to support the pump shaft components, there are two kinds of rolling bearings and sliding bearings. Rolling bearings use butter as a lubricant, fueling properly, usually 2/3~3/4 of volume, too much heat, too little, noise, and heat. Plain bearings are used as lubricant, and oil to the oil level line. Too much oil to be leaking along the shaft and low drift, too little overheated bearings burned to the accident! Bearing in the pump during operation the maximum temperature of 85 degrees in the general run of about 60 degrees, if we should find the reasons (whether there are impurities, oil is black, is water) and timely treatment!
First, the basic structure of the vertical pipe centrifugal pump is composed of six partsThe basic structure of a vertical pipe centrifugal pump consists of six parts, namely, impeller, pump body, pump shaft, bearing, sealing ring, stuffing box.1, the impeller is the core part of the centrifugal pump, it is high speed, large output, the impeller blade and play a major role in the impeller before assembly, through the static equilibrium experiment. The inside and outside surfaces of the impeller are required to be smooth, so as to reduce the friction loss of the water flow.2, pump body, also known as pump shell, it is the main body of the pump. The utility model is provided with a supporting and fixing function and is connected with a bracket for mounting the bearing.3, the role of the pump shaft is to use the coupling and motor connected, the motor transfer distance to the impeller, so it is the transfer of mechanical energy of the main components.
