Fountain pump the basic structure

The basic structure of the fountain pump is composed of six parts are the impeller, pump, pump shaft, bearings, seal ring, stuffing box.

1, the impeller is the core of the fountain pump, it is much higher speed, the impeller blade plays a major role in impeller assembly through static balance before the experiment. The inner and outer surfaces of the impeller are required to be smooth to reduce the friction loss of the water flow.

2, the pump body, also known as pump shell, which is the main fountain pump. To play a role in supporting the fixed and installed with the bearing bracket connected.

3, the role of the pump shaft is connected by the coupling and the motor, the motor torque to the impeller, so it is the transmission of mechanical energy of the main components.

4, the bearing is set in the pump shaft to support the shaft of the components, there are two kinds of rolling bearings and plain bearings. Rolling bearings using butter as a lubricant to the appropriate general is 2/3 ~ 3/4 of the volume too much heat, too little noise and fever! Sliding bearings use a transparent oil as a lubricant, refueling to the oil level line. Too much oil to bleed along the pump shaft and drift cheap, too little bearing but also overheating caused by accident! In the process of running the pump bearing the highest temperature of 85 degrees in the general operation of 60 degrees, if the high is necessary to find out the reasons (whether impurities, oil is black, whether the water) and timely treatment!

5, sealing ring, also known as leakage ring. Impeller inlet and pump shell gap between the General Assembly caused by high pressure within the pump area through the gap to the low pressure area, affecting the pump out of water, reduce efficiency! The gap is too small will cause friction between the impeller and the pump casing wear. In order to increase the return resistance to reduce the internal leakage, delay the life of the impeller and pump shell, the pump shell and the impeller at the outer edge of the foreign aid with sealing ring, sealed gap maintained between 0.25 ~ 1.10mm is appropriate.

6, stuffing box mainly by the filler, water ring, packing tube, packing gland, water pipe composition. The role of stuffing box is mainly to close the gap between the pump shell and the pump shaft to prevent the flow of water does not flow to the outside nor to the outside air into the pump. Always keep the vacuum inside the pump! When the pump shaft and packing friction generated by the heat will depend on the water sealing tube to the water seal ring to fill the cooling! To maintain the normal operation of the pump. So the pump running the inspection process to check the stuffing box is particularly important to note! In the run about 600 hours to fill the filler to be replaced.
