The utility model solves the water intake and the anti-corrosive problems of the electric motor, and has simple structure and light weight. When in working, the pump body is floated on the liquid surface, a blade wheel is submerged under the liquid surface, and the utility model has no need of exhausting air and filling liquid, no restriction by the suction lift and convenient move. The utility model pumps the supernatant liquid, and has small limit on the size, the color and the perimeter of the liquid and the bottom of the liquid. The utility model is suitable for pumping various liquid, and is also suitable for various working conditions.
Description
The utility model relates to a kind of centrifugal pump of carrying liquid, particularly a kind of floating pump.
In the prior art there be the structural type of centrifugal pump:
(1) general centrifugal pump.Separated motor and pump housing two large divisions connect with support, are furnished with imbibition bottom valve and pick-up tube, during use, and after the imbibition body is treated in the first exhaust of palpus, perfusion, can pump liquid.This structure benzene is heavy, and the suction journey of pumping liquid is limited.
(2) pump housing is immersed in the Under Water Pumps under the liquid.Pump is connected by baroque connecting tube with motor, and transmission shaft very long in the pipe is a set point value, and liquid level must be higher than pump housing impeller center line all the time during work, because of transmission shaft can not change with the height of liquid level, has been subjected to certain limitation so use.
(3) submersible pump.The motor and the pump housing are connected as a single entity and are immersed under the liquid.The motor strict seal of this pump, easy to use, but in order to prevent motor water inlet and motor radiating, complex structural designs, material requirements is tight, the manufacture cost height.
(4) floating pump.This structure swims in liquid level by the connection screw and the pump of motor front cover are direct-connected for one is connected with the circular shape buoyancy aid more as shown in Figure 1.This pump has solved a series of problems that are subjected to water body restriction, and the motor and the pump housing are exposed outside, surges or during liquid splash, motor is easily intake at liquid level; Because will solve sealing problem and will cause complicated structure again separating of buoyancy aid and motor, the pump housing, increase overall weight and increase the problem of volume, especially in corrosivity production environments such as chemical industry, the motor sealing needs the problem that solves especially.
The utility model has designed a kind of closed floating pump in order to overcome above-mentioned every the deficiencies in the prior art.This floating pump motor complete closed, triplicity becomes an integral body with buoyancy aid with motor, pump with compact, simple structure, and this structure organically combines prior art (three) and (fours') advantage.
For reaching above purpose, buoyancy aid of the present utility model is designed to a levitron, and it can guarantee that complete machine floats on liquid level, plays the buoyancy aid effect, itself again with motor, pump three compactly in conjunction with as a whole.Levitron is designed to the container shape that periphery is higher than the bottom, such as being designed to circular arc, ship shape or certain periphery other geometrical shape highly being arranged.A cylinder that is connected as a single entity with it is arranged in the levitron, be fixed with the motor outer cover in the cylinder, motor closely is sleeved in the motor outer cover, connect a motor bonnet on the motor outer cover again, outer cover and bonnet are tightly sealing motor, between motor outer cover and the cylinder certain space being arranged, is pumping chamber, and impeller directly is contained on the projecting shaft of motor in pumping chamber.
Motor of the present utility model adopts simple in structure, lightweight steel plate motor.
The bottom of levitron also is equipped with stability column, in stability column and the levitron foamed plastics is housed.Stability column can make levitron more stable on liquid level, and foamed plastics has increased the water displacement of levitron and stability column.
In order to prevent that better liquid splash from entering in the levitron, can be equipped with a buoyancy aid loam cake on the levitron, realize the top sealing.
The utility model is except that motor, and all the other component are working of plastics, and are in light weight, need not machining, and cost of production is low.
The utility model holds together motor and pump three by the cylinder in the levitron, and this structural type reduces component in a large number.Motor is totally-enclosed, has solved the anticorrosion problem of water inlet.Motor floats on liquid level, and except that motor shaft stretches into pumping chamber partly for the motive sealing, remaining part is static seal.During use, the pump housing floats on liquid level, and impeller is immersed under the liquid level all the time, need not exhaust, irritates liquid, exempts to use bottom valve, can carry liquid by self-priming, and the lifting with the lifting of liquid level, so there is not the restriction of the journey of suction, not limited by allowable suct lift.Complete machine is floating, and conveniently moving has been exempted the labor of fixing, installing, moving support, and is very easy to use, pumping and sucking liquid body upper clear liquid, as be used for pump water, to water body size periphery, the depth is minimum with water-bed restriction.
Motor of the present utility model can be for exchanging or direct current generator, and power supply can adopt electric main, also can adopt solar cells and wind-driven generator DC electrical source.This pump is applicable to food, pharmacy, chemical engineering industry and the irrigation of agricultural water, is applicable to that equally also industrial and mineral production, fire-fighting flushing etc. need the field of conveyance fluid.
Below in conjunction with accompanying drawing the utility model is described in further detail again.
Fig. 1 is the structural representation of existing floating pump.
Fig. 2 is the schematic representation of a kind of concrete structure of the present utility model.
With reference to Fig. 2, a cylinder that is connected as a single entity with it (11) is arranged in the levitron (12), motor outer cover (6) is packed in the cylinder (11), motor (7) just is installed in the motor outer cover (6), reconnect motor bonnet (9) above, motor down-lead (8) picks out from bonnet (9), and motor (7) is by totally-enclosed like this, and the waterproof of motor, anticorrosion problem are resolved.Design has certain space between motor outer cover (6) and the cylinder (11), and it is exactly pumping chamber (15), and impeller (3) is installed on the projecting shaft of motor (7) in pumping chamber (15), compact structure.
Complete machine floats on the liquid level under the floating function of levitron (12), has considered the weight effect of the pump housing self during design, and impeller (3) is immersed under the liquid level all the time, and pumping chamber (15) is full of liquid to be pumped.When motor (7) energising, impeller (3) rotation passes to liquid continuously to energy, the speed of the liquid in the pumping chamber (15) can be converted to the pressure energy, and under the effect of pressure energy, the liquid in the pumping chamber (15) is pumped away by outlet (5) and outlet pipe (4).Liquid below the levitron (12) constantly constantly enters pumping chamber (15) by the lower baffle (1) of stability column (14) and the inlet strainer (2) under the levitron again simultaneously, constantly pumps.The heat that produces in steel plate motor (7) work is taken out of outside the pump by the liquid that motor outer cover (6) passes in the pumping chamber (15), and the cooling problem of motor has also solved.
For stable and balance levitron and complete machine, the bottom water bottom of levitron also design and installation a stability column (14), the foamed plastic block (13) of increase water displacement also is housed in stability column (14) and levitron (12).Also installed one on the levitron (12) and can prevent that liquid from entering the buoyancy aid loam cake (10) in the levitron from top.
The utility model is except that motor (7), and all the other component are working of plastics, so not influenced by Environmental Conditions.
