1. Impeller is the core part of the centrifugal pump, it is high output power, the impeller on the blade and play a primary role in the assembly before the impeller through the static balance test. The inner and outer surface of the impeller is smooth, and the loss of the water flow is reduced.
2. Pump body, also known as pump shell, which is the main body of the pump. To play a supporting role, and with the installation of the bearing bracket.
3. The role of the pump shaft is connected with the motor through the coupling, the motor will be transferred to the impeller, so it is the primary component of mechanical energy transfer.
4. Bearing is set 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 to be appropriate fuel is usually 2 / 3 3 / 4 size too much may have a fever, there are too few sound and heat! Sliding bearings using transparent oil as lubricant, and fuel to the oil level line. Too much oil to leaking along the shaft and drift of base, too little overheated bearings and also burn caused by accident. In the operation of the water pump bearing temperature highest in 85 degrees usually operates at about 60 degrees, if high to find out the reasons (whether there are impurities, oil is black, is water) and timely treatment.
5. Sealing ring, also known as the reduction of leakage ring. The open space between the impeller and the pump shell over the general assembly caused by the flow of water pump, a high pressure area the space area of low pressure affect the pump out the water, reduce efficiency. Space too small will cause the impeller and the pump shell friction and wear. In order to increase the flow resistance reducing internal leakage, delayed the service life of the impeller and the pump shell and the impeller in the pump shell edge and foreign aid junction with sealing ring, sealing the space kept between 0.25 ~ 1.10mm appropriate.
6. Mainly by the stuffing box packing, seal ring, tube filler, filler cap, seal tubes. Filling function is mainly to close the open space between the pump shell and pump shaft, so that the pump does not flow inside the pump to the outside and do not let the outside air into the pump. Always keep the vacuum pump! When the pump shaft and filler conflict generates heat is depends on water seal on the living water to fill the cooling seal circle! Keep the pump's normal operation. Therefore, the operation of the pump in the process of inspection of the stuffing box is particularly to pay attention to in the operation of 600 hours or so to replace the filler.
