Summary of the invention
Problems and shortcomings at above-mentioned prior art existence, the utility model adopts elastic rubber material to make integrally-built rubber impeller, utilize elasticity, sheathed and the pliability of rubber tree leaf, make impeller blade can by crooked, reset at and rotate the technological scheme that the pump water conservancy project is done in the eccentric pump chamber cylinder chamber, a kind of elastic caoutchouc impeller of sea water pump is provided, be intended to substitute the telescopic impeller of rigid blade, make the rotator type sea water pump reach purpose simple in structure, that cost is low, rate of fault is low with the elastic caoutchouc impeller of overall simplification structure.
The purpose of this utility model is achieved in that a kind of elastic caoutchouc impeller of sea water pump, for by copper wheel hub and the compound impeller that is the cylindrical straight gear wheel shape that constitutes of rubber tree leaf wheel rim; Described copper wheel hub is the copper lining of cylindrical tubular that is positioned at the elastic caoutchouc impeller center of sea water pump; The central bore of copper wheel hub is provided with the flat key groove of rectangle;
Described rubber tree leaf wheel rim is that superpacket overlays on the rubber mass wheel rim that is provided with blade on the described copper wheel hub outer cylinder; The circumference of rubber tree leaf wheel rim be provided with some uniform five equilibriums, along the blade of diametric(al) straight plate shape radially, vane tip be provided with protrusion, along ridge hat ridge rib direction, columniform; Two ends of rubber tree leaf wheel rim are provided with the convex tendon of protrusion along the center of vane end faces; The length of rubber tree leaf wheel rim is greater than the length of described copper wheel hub, therefore respectively forms the stepped recesses of a dark circle such as mutual at two ends of two ends of copper wheel hub and rubber tree leaf wheel rim 2.
Working principle
The elastic caoutchouc impeller of sea water pump by with the rotating shaft flat key connection set of sea water pump in the cylinder chamber of sea water pump pump chamber off-centre, by the rotating shaft rotary driving, the blade that is positioned at wall place, cylinder far away chamber is unfolded, the ridge hat elasticity sliding motion contact of this blade is on the wall of cylinder chamber, be positioned at the bending blade at wall place, nearly cylinder chamber, the ridge of this blade is preced with also elasticity sliding motion contact on the wall of cylinder chamber; When wall place, nearly cylinder chamber was left in the blade rotation, blade elasticity was stretched out, and volume increases between the adjacent blades, and pressure reduces to produce negative pressure, and water is from suction cylinder chamber, water inlet; When blade rotates into wall place, nearly cylinder chamber, the blade elastic bending, volume reduces between the adjacent blades, produces malleation, and water is extruded through water outlet from the cylinder chamber; In rotary course, each blade is stretched out successively with bending and is finished pump water conservancy project work.
Above-mentioned, the utility model adopts elastic rubber material to make integrally-built rubber impeller, utilize the elasticity of rubber tree leaf, sheathed and pliability, make the blade of impeller can pass through crooked, reset at and rotate the technological scheme that the pump water conservancy project is done in the eccentric pump chamber cylinder chamber, the elastic caoutchouc impeller of a kind of sea water pump that is provided, overcome prior art and had complex structure, the cost height, the problems and shortcomings that rate of fault is high, substitute the telescopic impeller of rigid blade by elastic caoutchouc impeller, make the rotator type sea water pump reach simple in structure with the overall simplification structure, cost is low, the purpose that rate of fault is low.
