Abstract
The utility model discloses a spindle type bulb tubular pump device and belongs to the technical field of pump station devices. The spindle type bulb tubular pump device comprises a water inlet flow channel, an impeller, a guide vane, a water outlet flow channel and a bulb body arranged in the water outlet flow channel, the water inlet flow channel, the impeller, the guide vane, the water outlet flow channel and the bulb body are connected and arranged in sequence, the bulb body is in a spindle type, and the unilateral spread angle of the outlet side of the guide vane and the bulb body is 7 degrees. The spindle type bulb body is of a half-and-half structure and is formed by welding metal materials. The water outlet flow channel is of a concrete structure. The length of the spindle type bulb body is 5.3 times of the diameter of the impeller. According to the spindle type bulb tubular pump device, on the basis of the principle that flow speed in a flow channel is evenly spread, the situation that the flow speed is suddenly decreased to cause the increase of hydraulic losses is avoided, the spindle type is adopted by the bulb body of a bulb tubular pump, and the unilateral spread angle of the outlet side of the guide vane and the bulb body is 7 degrees. Relative to a traditional bulb tubular pump, the pump device enables water outlet hydraulic losses to be greatly reduced, can effectively lower project investment and operation cost, ensures the safe, high-efficiency and reliable operation of a unit, effectively improves device efficiency, and saves energy.
Description
Technical field
The utility model relates to the bulb through-flow pump-unit, particularly spins the structural type of tapered bulb through-flow pump-unit, belongs to pumping plant device technique field.
Background technique
The bulb through-flow pump has characteristics such as lift is low, flow is big, horizontal layout, set structure compactness as the pump type that adapts to than low lift, has that runner is straight, hydraulic loss is little, the unit efficiency advantages of higher.Its main feature is that motor is installed in the bulb, has guaranteed the direct transmission of motor and water pump.But the domestic bulb through-flow pumping plant bulb of having built is shorter at present, and motor mounting space is little, exists efficiency of pumping station not reach needs of expected design simultaneously.
The model utility content
The purpose of this utility model is exactly the deficiency that exists at above-mentioned existing bulb through-flow pump, solve the low problem of the improper efficiency of pumping station that causes of bulb through-flow pump motor installing space problem and bulb partial design, provide a kind of structural type simple, the pump-unit whole efficiency is high spins tapered bulb through-flow pump-unit.
The purpose of this utility model is to realize like this, spin tapered bulb through-flow pump-unit, comprise water inlet flow channel, impeller, stator, the outlet passage that sets gradually connection and be arranged on bulb in the outlet passage, it is characterized in that, described bulb is tapered for spinning, and the monolateral angle of flare of stator and bulb outlet limit is 7 degree.
Described to spin tapered bulb be double structure, adopts Metal Material Welding to constitute.
Described outlet passage is concrete structure.
The described length of spinning tapered bulb is 5.3 times of described impeller diameter.
The described Extreme breadth that spins tapered bulb is 0.95 times of described impeller diameter.
The utility model is rational in infrastructure simple, and based on the even diffusion principle of flow velocity in the runner, the hydraulic loss of avoiding the unexpected minimizing of flow velocity to cause increases, and the bulb shape of bulb through-flow pump adopts to be spun taperedly, and the monolateral angle of flare of stator and bulb outlet limit is 7 degree.This spins tapered bulb through-flow pump-unit and reduces greatly with respect to conventional bulb through-flow pump water outlet hydraulic loss, can reduce construction investment and operating cost effectively, guarantees the operation of unit safety high efficient and reliable, has improved unit efficiency effectively, has saved the energy.
