Wheel.
Background technology
Since seawater has corrosivity, the impeller of the rotor sea water pump of the prior art is the telescopic impeller of rigid blade, is
It is made of copper or stainless steel, refering to Fig. 4, the rigid blade of impeller is rotated with the shaft of impeller in eccentric pump chamber when work,
Blade of the sliding in shaft telescopic chute needs constantly to carry out stretching motion under the action of the spring, thus complicated,
It is of high cost, and malfunctioning node is more；If impurities in water enters the stretching motion failure that blade telescopic chute leads to blade, will occur
" seizing stuck " or leak idle running failure, therefore, the prior art there are problems that complicated, of high cost, high failure rate with
It is insufficient.
By retrieval, a Chinese patent open source literature similar with present patent application, a kind of entitled sea water pump are found
Elastic rubber impeller, notification number be CN 202056049U.The publication includes being answered by copper wheel hub and rubber tree leaf wheel rim
Close the impeller in cylindrical straight gear wheel shape constituted；The copper wheel hub is the circle positioned at the elastic rubber impeller center of sea water pump
The copper bushing of cylindricality tubulose；The central bore of copper wheel hub is equipped with the flat key slot of rectangle；The rubber tree leaf wheel rim is multiple
Conjunction, which is coated on the copper wheel hub outer cylinder, sets vaned rubber mass wheel rim；If the circumference of rubber tree leaf wheel rim is equipped with
Dry plate is evenly distributed with decile, slide plate shape diametrically radially blade, and vane tip is equipped with protrusion, along ridge rib side
To, cylindrical ridge hat；Two ends of rubber tree leaf wheel rim are equipped with the convex ribs of protrusion along the center of vane end faces；Rubber tree leaf
The length of wheel rim is more than the length of the copper wheel hub, therefore in each shape in two ends at two ends of copper wheel hub and rubber tree leaf wheel rim
Deep circular stepped recesses are mutually waited at one.
It is found by comparing, the impeller of documents is pumped in sea water pump by the shaft flat key attachment device with sea water pump
In the cylinder chamber of room bias, stress point is in the both sides of flat key slot, discontinuity, and torque is smaller；In seawater pump work, blade
Can switch under two states being bent and unfold always, in the course of time, the ageing of rubber of blade is very fast, can not normally be bent and
Unfold, to will appear the phenomenon that leak is dallied, refering to Fig. 3.
Utility model content
To overcome the above-mentioned deficiency of the prior art, the purpose of this utility model is to provide one kind can be when impeller works
The toughness and elasticity that blade can be protected extend a kind of elastic rubber impeller of sea water pump of its service life.
The technical scheme adopted by the utility model is that：
A kind of elastic rubber impeller of sea water pump, including copper wheel hub, rubber tree leaf wheel rim, blade and reinforcement wing, institute
It is cylindrical to state copper wheel hub；Center bore inner wall positioned at the copper wheel hub in the center of the elastic rubber impeller of sea water pump is axial
It is uniformly formed with continuous fin, the continuous fin is fixed outer groove with the shaft of sea water pump and is adapted；
The rubber tree leaf wheel rim is coaxially to be coated on copper hub outer wall；It is axial on the outer wall circumference of rubber tree leaf wheel rim
Interval is integrally formed with several blades, and blade is the blade of slide plate shape diametrically radially, and blade tip is circle
Arc；
The both sides of the blade are formed with reinforcement wing, and the length of the rubber tree leaf wheel rim is more than the length of the copper wheel hub
It spends, the both ends of copper wheel hub respectively form one with the both ends of rubber tree leaf wheel rim and mutually wait deep circular stepped recesses.
The advantages of the utility model and good effect:
1, the elastic rubber impeller of a kind of sea water pump provided by the utility model makes whole knot using elastic rubber material
The rubber impeller of structure enables the blade of impeller by being bent, resetting using the paddles elastomeric, bendability and flexibility of rubber
The work of rotation water pumping is carried out in eccentric pump chamber cylinder intracavitary, makes simple in structure, cost reduction.
2, the elastic rubber impeller of a kind of sea water pump provided by the utility model, every blade both sides coaxial-symmetrical, which is formed with, to be added
Strong wing, when which is bent, the reinforcement wing for the side being bent is supported on rubber tree leaf wheel rim, to support blade, thus
The toughness and elasticity for protecting blade, improve the service life of impeller.
3, the elastic rubber impeller of a kind of sea water pump provided by the utility model, the copper wheel hub are positioned at sea water pump
Elastic rubber impeller center cylindrical copper bushing；The central bore of copper wheel hub is uniformly formed with continuous fin,
The continuous fin is adapted with the fixation outer groove of the shaft of sea water pump, keeps the shaft junction stress of impeller and sea water pump equal
It is even, reduce the failure of impeller work.
