The conjugate symmetric rotating self-priming pump comprises a pump body and a pump shaft, wherein a pump cavity is formed in the pump body; a runner and a middle partition board sliding block are arranged in the pump cavity; the middle partition board sliding block divides the pump cavity into a left cavity and a right cavity; rotating sheets are arranged in the left cavity and the right cavity respectively; the two rotating sheets have the identical shape and are arranged in a conjugate symmetric mode to maintain balance. A piston and a speed reducer can be saved, so the conjugate symmetric rotating self-priming pump has simple structure, few parts, low noise, stable performance and high efficiency, and saves energy.
Description
Technical field
The utility model relates to a kind of self-priming pump, relates in particular to a kind of conjugation symmetry rotation self-priming pump.
Background technique
Self-priming pump is an industrial field pump commonly used, and volume self-priming pump of the prior art generally is a screw pump, a little less than the strong pump water of screw pump pump oil.Present oil field secondary oil recovery is most ofly used multistage centrifugal pump, and centrifugal pump pump water is strong, pump oily a little less than.These two kinds of pump structure complicacies, noise height, unstable properties, energy consumption height, and, must increase speed reducer in the course of the work because the rotating speed of traditional displacement pump is low.The centrifugal pump rotating speed is high, and fault is high.
The model utility content
The purpose of the utility model provide a kind of simple in structure, parts are few, noise is low, stable performance, energy-efficient conjugation symmetry rotation self-priming pump.
The purpose of the utility model realizes through following technological scheme:
The conjugation symmetry rotation self-priming pump of the utility model comprises the pump housing, pump shaft, and pump housing inside is pump chamber; Be provided with central diaphragm slide block and runner in the said pump chamber; Said central diaphragm slide block is fixedly connected with the said pump housing, and said central diaphragm slide block is divided into left chamber and right chamber with said pump chamber, is respectively equipped with blade in said left chamber and the right chamber; Said blade is fixedly connected with said pump shaft; The axial dimension of said blade one side is greater than the axial dimension of opposite side, and the shape of two blades is in full accord, and two blades are the conjugation symmetric arrangement.
Technological scheme by above-mentioned the utility model provides can find out that the conjugation symmetry rotation self-priming pump that the utility model provides is owing to be provided with the central diaphragm slide block in the pump chamber; The central diaphragm slide block is divided into left chamber and right chamber with said pump chamber, is respectively equipped with blade in left chamber and the right chamber, and blade is fixedly connected with pump shaft; The axial dimension of blade one side is greater than the axial dimension of opposite side; The shape of two blades is in full accord, and two blades are the conjugation symmetric arrangement, keeps balance.Can omit piston and speed reducer, simple in structure, parts are few, noise is low, stable performance, energy-efficient.

Embodiment
To combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
The conjugation symmetry rotation self-priming pump of the utility model, its preferable embodiment is:
Comprise the pump housing, pump shaft, pump housing inside is pump chamber, is provided with central diaphragm slide block and runner in the said pump chamber; Said central diaphragm slide block is fixedly connected with the said pump housing, and said central diaphragm slide block is divided into left chamber and right chamber with said pump chamber, is respectively equipped with blade in said left chamber and the right chamber; Said blade is fixedly connected with said pump shaft; The axial dimension of said blade one side is greater than the axial dimension of opposite side, and the shape of two blades is in full accord, and two blades are the conjugation symmetric arrangement.
The occlusal surface of two blades is a time pendulum column rule face.
The material of said blade is that high molecule nano composite material is made.
The interior survey of end cap is located in sealing, and bearing is located at the outside of end cap.
In the utility model, the shape of two blades is in full accord, and two blades are the conjugation symmetric arrangement, keeps balance.Time pendulum column rule technology is adopted in blade production, to guarantee that on the blade each select all parallel with pump shaft and if each parallel symmetric points all were the slits that do not have of interlock after two blades combined.The blade material adopts high molecular nanometer composite material (PPESK) to make.The interior survey of end cap is located in sealing, and bearing is located at the outside of end cap, has reached bearing like this and has separated with meson, to reduce the loss of meson to bearing.
Specific embodiment:
Like Fig. 1, Fig. 2, shown in Figure 3, whole unit comprises assemblies such as motor, base, coupling, safety enclosure.The pump housing 4, pump shaft 1, blade 5, central diaphragm slide block 6, sealing 3, bearing 2, logically cover 7, end cap 8 is critical piece.
Its working principle is:
A pair of blade is as the criterion with the central diaphragm slide block and divides right and left; Respectively formed in the both sides of central diaphragm slide block a shape end face in full accord, blade stagger mutually 180 degree, blade height complementary, the ring-type wedge shape space; The working room, the left and right sides of Here it is pump also claims swept volume.Be divided into hyperbaric chamber and low pressure chamber to working room, the left and right sides again, low pressure chamber communicates with inlet, and hyperbaric chamber communicates with outlet.When the continuous rotation synchronously of paired blade, hyperbaric chamber and low pressure chamber alternately realize descending, suck liquid from zero to maximum, pressure; Again from be up to zero, pressure rises, the circulation change of drain.It promptly is the working principle of rotation self-priming pump.
The utility model has the advantages that:
Symmetric design can positive and negatively be imported fully, has the strong point of displacement pump pump oil, possesses the advantage of centrifugal pump pump water again.Axle, pulse is little, noise is low, stable performance, energy-efficient, compare with conventional pump and not to be with speed reducer; Simple in structure, volume is little, pump is few, suction is strong, the life-span is long; Core component adopts high molecule nano composite material (PPESK material), light specific gravity, intensity height, and corrosion resistant is wear-resistant indeformable.
The above; Be merely the preferable embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claims.
