Abstract
This utility model provides a kind of LNG low temperature immersed pump inducer, is related to mechanical engineering pump class technical field, and inducer is the little Double cone structure in two broad in the middle, and blade pitch is equal.The LNG low temperature immersed pump inducers that this utility model is provided, are a kind of ultralow cavitation inducers.Inducer adopts biconial structure, and the structure inlet -duct area large outlet area is little, can increase the area of passage of entrance, so as to improve the anti-cavitation performance of inducer itself；Diconical airflow design, can form good flow regime, pressure and VELOCITY DISTRIBUTION in impeller eye；Uniform pitch shape blade, simple structure, processing cost are low.
Description
Technical field
This utility model is related to mechanical engineering pump class technical field, and in particular to LNG low temperature immersed pump inducers.
Background technology
The application of low temperature LNG pump is more special, mostly inflammable, the explosive low temperature of pumped (conveying) medium or super-low liquid,
This harsh working condition determines that this kind of pump has to possess good cavitation performance and hydraulic performance.Traditional inducer
Do not possess anti-cavitation performance, it is impossible to adapt to harsh working condition.
Utility model content
A kind of LNG low temperature immersed pump induction that this utility model is aiming at the problem of above-mentioned background technology presence and invents
Wheel, solves inducer and does not possess anti-cavitation performance, it is impossible to adapt to the problem of harsh working condition.
The technical solution adopted in the utility model is：
A kind of LNG low temperature immersed pump inducer, it is characterised in that：Inducer is the little Double cone structure in two broad in the middle,
Blade pitch is equal.
The beneficial effects of the utility model：
The LNG low temperature immersed pump inducers that this utility model is provided, are a kind of ultralow cavitation inducers.Inducer is using double
Pyramidal structure, the structure inlet -duct area large outlet area are little, can increase the area of passage of entrance, so as to improve inducer itself
Anti-cavitation performance；Diconical airflow design, can form good flow regime, pressure and speed point in impeller eye
Cloth；Uniform pitch shape blade, simple structure, processing cost are low.
Description of the drawings
Accompanying drawing is structural representation of the present utility model.
Wherein, 1, impeller 2, inducer 3, water inlet end.
Specific embodiment
As illustrated, a kind of LNG low temperature immersed pump inducer, inducer is the little Double cone structure in two broad in the middle, leaf
Piece pitch is equal.The wheel hub structure of inducer is designed to into the little Double cone structure in two broad in the middle, blade design is uniform pitch
Form, inducer are arranged at (chopped-off head) impeller eye, and inlet segment shape is with inducer profile (two broad in the middle is little), inducer
Blade outer rim keeps suitable spacing with inlet segment runner.Inducer has anti-cavitation performance, is a kind of ultralow cavitation inducer,
Uniform pitch shape blade, simple structure, processing cost are relatively low.
Claims (1)
1. a kind of LNG low temperature immersed pump inducer, it is characterised in that：Inducer is the little Double cone structure in two broad in the middle, leaf
Piece pitch is equal.
