With the rapid development of chemical, textile, metallurgy, energy and other fields, the matching products in these fields have also made great progress. Taking pipeline centrifugal pump as an example, as a representative of the potential star in centrifugal pump, it has unique advantages in liquid transportation and is especially suitable for the work of chemical industry, textile, metallurgy and energy. Understanding pipeline centrifugal pumps can certainly play an important role in these areas. Next, a detailed analysis of the pipeline centrifugal pump structure. Pipe centrifugal pump structure Figure 1, the impeller: Centrifugal pump is the core part of its high speed, the impeller blades play a major role in the 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, the pump body: pump casing, it is the main pump. To support the role of fixed, and with the bearing bracket to connect. 3, pump shaft: The role of the pump shaft is connected to the motor by the coupling, the motor torque to the impeller, so it is the main component of mechanical energy transmission. 4, Bearing: It is a set of components that support the pump shaft on the pump shaft. There are two kinds of rolling bearings and plain bearings. Rolling bearings using butter as a lubricant, appropriate to the fuel, usually 2/3 to 3/4 of the volume: too much heat, too little sound and fever. 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 this gap, affecting the output of the pump and reducing the efficiency. The gap is too small will cause the impeller and the pump shell friction wear. 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. Professionals often give advice to new users, they often recommend users to use the new equipment to understand, familiar with the structure of the device. This shows the structure of the device for the importance of equipment. We all know that the chart not only helps users to use the device better, but also can have a significant impact on the repair and protection of later devices. For those who intend to use or just use a pipe centrifugal pump, a better understanding of the pipeline centrifugal pump structure will definitely have a positive impact on the use of the pipe centrifugal pump.
