Abstract
The utility model provides a convenient disassembly type centrifugal pipeline pump which comprises a pump body (1), a pump cover (2), an impeller (3), a pump shaft (4), a bearing seat (5), a motor frame (6), a motor (9), an intermediate joint (7) and a diaphragm coupling (8). The pump shaft has high installation accuracy and good transmission stability; only the intermediate joint (7) needs to be disassembled to disassemble and maintain the bearing seat (5), the pump cover (2) and the pump shaft (4); and the motor does not need to be disassembled; therefore, the maintenance is convenient.
Description
Technical field
The utility model relates to the riser pump.
Background technique
Riser pump kind is more, and main structure is vertical coaxial construction, and motor is the pipeline mounted pump motor special, impeller is directly installed on the motor shaft of lengthening, though axial dimension is short, pump rotor supports by motor bearings, causes motor shaft carrying power excessive, damage easily, reduced the working life of pump, maintenance cost improves, and is difficult for pump is dismantled maintenance, need pull down motor during maintain and replace pump accessory, waste time and energy.
The model utility content
It is convenient that the purpose of this utility model provides a kind of mounting or dismounting, the riser centrifugal pump of being convenient to keep in repair.
The utility model is by the pump housing 1, pump cover 2, impeller 3, pump shaft 4, bearing support 5, motor frame 6, motor 9, middle segmentum intercalaris 7, diaphragm coupling 8 constitutes, the pump housing 1, pump cover 2, motor frame 6 is mutually permanently connected together by bolt, bearing support 5 is fixedlyed connected with pump cover 2 upper ends by bolt, pump shaft 4 is rotatably installed on the bearing support 5 by bearing, the upper end of pump shaft 4 is connected with middle segmentum intercalaris 7 flanges butt joint by coupling 41, motor shaft 91 is connected with middle segmentum intercalaris 7 by diaphragm coupling 8, be provided with mechanical seal device 24 and backbone sealing ring 25 at pump cover 2 and 4 of pump shafts, on pump cover 2, offer the discharge orifice 27 that communicates with the inner chamber A of 25 of mechanical seal device 24 and backbone sealing rings, offer on pump cover 2 and have cooling inlet opening 28, cooling inlet opening 28 is communicated with the pump housing 1 liquid outlet end by connecting tube 29.
The utility model is rational in infrastructure, special-purpose pump shaft is connected with motor shaft by diaphragm coupling, make motor shaft and pump shaft good stress performance, pump shaft installation precision height, transmission stability is good, stable working, have enough spaces on motor frame 6, and pump shaft 4 is connected with coupling by middle segmentum intercalaris 7 with motor shaft 91, segmentum intercalaris 7 just can be dismantled and keep in repair bearing support 5, pump cover 2, pump shaft 4 in only need pulling down, do not need to dismantle motor, easy to maintenance.
