Abstract
The invention discloses a split heat-insulation double-sided impeller structure which comprises a large impeller 1 and a small impeller 2, wherein the large impeller 1 and the small impeller 2 are arranged axially in an interference fit manner, after being assembled, the large impeller 1 and the small impeller 2 form a heat-insulation structure 3 at the back of the impeller, and the heat-insulation structure is internally filled with a heat-insulation material or a coating with end surface coated with zirconium oxide. For a double-sided cooling water pump of a high-low-temperature double-loop cooling system meeting the application of a diesel engine, the working temperatures of cooling media at two sides of the impeller are commonly different, if the heat-insulation measure is not taken, the impeller is made of metals, so that strong heat transfer capability causes large influence on the heat dissipation at two sides during long-time working. The split heat-insulation impeller adopted can reduce the mutual temperature influence of two high-low-temperature sides, and meet the long-time working demand of high-low-temperature loops.
Description
Technical field
Technical field of the present invention is the rotating machinery field, realizes that especially same water pump satisfies the impeller of two kinds of different temperatures work requirements.
Background technique
application number a kind of Centrifugal water pump water pump that has been 201010197780.5 Patent Application Publication, comprise transmission shaft, bearing, fastening piece, bearing support, spiral case, water inlet coupling plate, impeller and mechanical seal, impeller comprises linear leaf and short blade, each 5 alternate layouts of linear leaf and short blade, blade intermediate shaft hole diameter 18mm, hub diameter 24mm, impeller outer diameter 133.6mm, long, the short blade inlet diameter is 66mm, long, short blade import laying angle is 36 °, long, the short blade inlet height is 17mm, long, short blade thickness is 3.5mm, long, short blade outlet laying angle is 45 °, long, it is 10.3mm that short blade goes out open height.Runner and the impeller of spiral case are complementary, and water inlet coupling plate suction chamber tapering is 12.5 °.This water pump is energy-efficient, and processability is good, and efficient is high, lightweight, volume is little.But owing to there being two cooling circuits of high low temperature on motor, the temperature difference of cooling liquid is larger in these two loops, this water pump can only drive a cooling liquid in the loop, so the high coolant cooling circuit on motor must adopt two water pumps, does not satisfy the compactedness that complete machine is arranged.
Adopt high low temperature loop cooling system to realize that High-temperature cooling is the developing direction of internal-combustion engine cooling system.In order to satisfy the compactedness of integral arrangement, the two-sided blade water pump has appearred, and can adopt a whole water pump to realize that the cooling liquid that satisfies two loops drives demand.
Usually water pump vane adopts metallic material, and the coolant temperature of double-impeller both sides differs more than 30 ℃, the heat transfer of double-impeller is larger on the temperature impact of both sides cooling liquid, and the impact that temperature variation causes the cooling circuit coupling causes the reliability that the engine operation environment is abominable, affect motor.
Summary of the invention
Be the interactional technical problem of coolant temperature of the high low-temperature circuit that solves two-sided water pump vane both sides, the present invention improves two-sided water pump vane, has designed a kind of split type heat insulation blade wheel structure.
Technological scheme of the present invention is:
A kind of split type heat insulation double-impeller structure, comprise large impeller 1, small impeller 2, large impeller 1 and small impeller 2 be interference fit in the axial direction, takes turns back of the body place's formation heat-insulating structure 3 at impeller after impeller 1 assembles with small impeller 2 greatly, heat-insulating structure 3 end faces spraying zirconia coatings.
A kind of split type heat insulation double-impeller structure, comprise large impeller 1, small impeller 2, large impeller 1 and small impeller 2 be interference fit in the axial direction, forms heat-insulating structure 3 at impeller wheel back of the body place after large impeller 1 and small impeller 2 assemblings, and heat-insulating structure 3 inside are filled with thermal-protective material.
Preferred thermal-protective material is asbestos.
The thickness of the heat-insulating structure 3 at the impeller wheel back of the body place of large impeller 1 and small impeller 3 is the 3-5 millimeter.
Beneficial effect of the present invention is: by increase heat-insulating structure on two-sided water pump vane, can reduce influencing each other of media of both sides different operating temperature.Satisfy the long-term stable operation in two loops.Adopt this split type heat insulation double-impeller structure, owing to having adopted split-type structural can realize heat insulation measures, reduced the heat output of impeller, make the minimizing that influences each other of the coolant temperature of both sides, satisfy the demand of diesel engine long-term work.
