Interpretation of the working principle of horizontal pipeline pump - horizontal pipeline pump structure

Horizontal pipeline pump is a centrifugal pump, its working principle in addition to the general characteristics of the centrifugal pump, because of its differences in purpose and structure, and has its own characteristics. First, the working principle of a horizontal pipe pump 1, suction pressure ≤ 1.6MPa, or the maximum working pressure of the pump system ≤ 1.6MPa, the pump inlet pressure + pump head ≤ 1.6MPa, pump static pressure test pressure of 2.5MPa, when ordering Please indicate the system pressure. Pump system operating pressure greater than 1.6MPa should be separately ordered when ordering, in order to manufacture pump overcurrent part and the coupling part of the cast steel material. 2, ambient temperature <40 ℃, relative humidity <95%. 3, the conveying medium solid particles volume content does not exceed 0.1% of the unit volume, particle size <0.2mm. Second, the structure of horizontal pipe pump Third, the structural characteristics of horizontal pipe pump 1, the pump is a vertical structure, import and export of the same caliber, and located in the same center line, the valve can be installed in the same pipeline, shape Compact and beautiful, small footprint, low construction investment, such as with the protective cover can be placed outdoors. 2, the impeller is directly mounted on the extended shaft of the motor, the axial dimension is short, the structure is compact, the configuration of the bearing of the pump and the motor is reasonable, the radial and axial loads generated by the pump operation can be effectively balanced, thereby ensuring the smooth operation of the pump, Vibration noise is low. 3, shaft seal mechanical seal or mechanical seal combination, the use of imported titanium alloy seal, medium-temperature mechanical seal and the use of hard alloy material, wear-resistant seal, can effectively increase the service life of mechanical seals. 4, easy installation and maintenance, without moving the piping system, as long as you remove the pump seat nut can be pulled out all the rotor components. 5, according to the requirements of the use of flow and lift needs of the pump string, parallel operation. 6, according to the requirements of the pipeline layout using vertical and horizontal pump installation.
