Technical field
The utility model relates to a kind of anti-whirlpool flow guide device, more particularly, relates to the anti-whirlpool flow guide device of a kind of pump sump.
Background technique
As everyone knows, the flowing of any real fluid all has two kinds of nowed formings, i.e. turbulent flow and laminar flow.The flow shape of the water sucking mouth of water pump suction pipe is generally in turbulent condition, and current can form little whirlpool one by one, and the pressure in whirlpool center portion is lower, easily by air intake, one denier air enters water pump suction pipe, will increase the resistance of conveyance conduit, and produces cavitation erosion to water pump vane.At present for solving this problem, the general method adopting reduction water sucking mouth water velocity, the 1.3-1.8 mainly extend outward water sucking mouth to suction sleeve diameter doubly forms horn mouth, during use, the height of horn mouth distance pond (water tank) bottom is greater than suction sleeve diameter, and the lowest water level of pond (water tank) needs exceed horn mouth 1.5-2.0 suction sleeve diameter height and be not less than 0.5 meter, therefore, bottom, pond (water tank) must retain the depth of water region of 2.0-3.0 suction sleeve diameter height as water suction zone of protection, the volume of this water suction zone of protection cannot be utilized.
Summary of the invention
1. the model utility technical problem that will solve
The purpose of this utility model is to overcome above-mentioned deficiency, provide the anti-whirlpool flow guide device of a kind of pump sump, adopt the technical solution of the utility model, structure is simple, design ingenious, using effect is good, the generation of eddy current when preventing pumping for water pump by forming multiple guide channel, and can reduce the depth of immersion needed for pump sump mouth.
2. technological scheme
For achieving the above object, the technological scheme that the utility model provides is:
The anti-whirlpool flow guide device of a kind of pump sump of the present utility model, it is characterized in that: comprise baffle upper plate, the structure shape of described baffle upper plate is spherical shape to lower recess or conical surface-shaped, the center of the baffle upper plate of this spherical shape or conical surface-shaped is provided with flanged surface, and the center of this flanged surface offers pump sump mouth; The below of described baffle upper plate is provided with lower horizontal guide plate, is provided with multiple directing vane between this lower horizontal guide plate and baffle upper plate; Be provided with angle between described directing vane and baffle upper plate, this angle is greater than 0 ° and is equal to or less than 90 °, and multiple directing vane with pump sump mouth axis for interval, the center of circle annular arranged.
Further, described multiple directing vanes with pump sump mouth axis for equal angles interval, the center of circle annular arranged.
3. beneficial effect
The technological scheme adopting the utility model to provide, compared with existing known technology, has following beneficial effect:
(1) the anti-whirlpool flow guide device of a kind of pump sump of the present utility model, the structure shape of its baffle upper plate is spherical shape to lower recess or conical surface-shaped, the center of the baffle upper plate of this spherical shape or conical surface-shaped is provided with flanged surface, the center of this flanged surface offers pump sump mouth, the below of baffle upper plate is provided with lower horizontal guide plate, multiple directing vane is provided with between this lower horizontal guide plate and baffle upper plate, angle is provided with between this directing vane and baffle upper plate, this angle is greater than 0 ° and is equal to or less than 90 °, and multiple directing vane 2 with pump sump mouth 11 axis for interval, the center of circle annular arranged, baffle upper plate, lower horizontal guide plate and the directing vane be arranged between lower horizontal guide plate and baffle upper plate form multiple guide channel, by changing the direction of a stream of water and water velocity, the generation of eddy current when effectively preventing water pump from drawing water in water tank, and the depth of immersion that can reduce needed for pump sump mouth, and due to the structure shape of baffle upper plate be spherical shape to lower recess or conical surface-shaped, make more not easily to produce whirlpool,
