Abstract
The utility model discloses a blade-adjustable vertical axial pump which comprises an electric motor and is characterized in that the electric motor is arranged on a barrel-shaped chassis which is arranged on a pump bracket; the middle of the pump bracket forms an enclosed cavity; the upper and the lower ends of the pump bracket are respectively provided with a bearing seat; a filling sealing seat is positioned in the cavity; the rotating shaft of the electric motor penetrates through the barrel-shaped chassis and is connected with a pump shaft through a coupler; a bearing set is arranged between the pump shaft and the bearing seat; the two ends of the bearing set are provided with bearing end covers; a mechanical seal and a filling seal are arranged between the pump shaft and the filling seal; the front end of the pump shaft is provided with an impeller seat which is provided with blades; and the top of the pump shaft is provided with a water guide bowl. The utility model discloses a novel axial pump. Compared with the prior art, the blade-adjustable vertical axial pump has great single-level flow rate, wide pump lift amplitude, high efficiency, strong adaptability, no vibration, high reliability and low noise, and is widely applicable to city water supply and drainage, circulation water supply in a thermoelectric station, agricultural water drainage and irrigation and other water conservancy projects.
Description
Technical field
The utility model belongs to a kind of pump, specifically is the adjustable vertical-type axial-flow pump of a kind of blade.
Background technique
The adjustable vertical-type axial-flow pump of blade is widely used in urban water supply and sewerage, cogeneration power plant delivery cycle water, agricultural irrigation and drainage and other hydraulic engineering.Form by the pump housing, pump support, pump shaft, impeller etc., but defective such as the existing adjustable vertical-type axial-flow pump of blade exists the lift amplitude low, and pump duty is little.
The model utility content
The purpose of this utility model provides the adjustable vertical-type axial-flow pump of a kind of blade, and is rational in infrastructure, and the lift amplitude is big, and pump duty is big, the advantage that efficient is high.
The technical solution of the utility model is as follows:
The adjustable vertical-type axial-flow pump of blade, include motor, it is characterized in that: described motor is installed on the tubular support, the tubular support is installed on the pump support, constitute sealed hollow in the middle of the pump support, on the pump support, following two ends are separately installed with bearing support, the packing seal seat is positioned at described cavity, machine shaft passes the tubular support, connect with pump shaft by coupling, between pump shaft and the bearing support bearing pack is installed, the bearing pack two ends are equipped with bearing (ball) cover, be provided with mechanical seal and packing seal between pump shaft and the packing seal seat, the pump shaft front end is equipped with impeller base, and blade is installed on the impeller base, and the pump shaft top is equipped with the diversion bowl.
The adjustable vertical-type axial-flow pump of described blade is characterized in that described mechanical seal is provided with cooling jacket outward.
Compare with prior art, blade is adjustable, and vertical-type axial-flow pump single-stage flow is big, the lift amplitude broad, and the efficient height, adaptability is strong, friction, the reliability height, noise is low, is widely used in urban water supply and sewerage, cogeneration power plant delivery cycle water, agricultural irrigation and drainage and other hydraulic engineering.
