Description
Technical field
The utility model relates to rotor pump field, especially a kind of large discharge rotor pump.
Background technique
A lot of pumping units of current use do not possess self-priming performance; foreign matter passes through poor performance; conveying is not steadily, vibrations are large, noise is high; easy generation axle is inclined and wear and tear; working life is short, and component cost is high, and occupation of land space is large; need during maintaining to dismantle whole pipeline, upkeep operation is loaded down with trivial details and cause dead time very long.
Therefore, need to solve the technical problem such as conveying capacity, smoothness, reduction noise of elevator pump, realize the realistic problem in the work such as water supply operation of current water treatment, effluent discharge, mud discharging, waterworks.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art, provide a kind of large discharge rotor pump, by the redesign to rotor structure size, under the prerequisite meeting economic benefit, make that the increased flow capacity of rotor pump, pressure raise, application area is wider.
The utility model object realizes being completed by following technological scheme:
A kind of large discharge rotor pump, described rotor pump comprises motor, speed reducer, connecting shaft, base, shell and rotor, the output terminal of described motor connects described speed reducer, described speed reducer connects the described connecting shaft of driving, described connecting shaft is arranged in the axis hole of described rotor, described rotor is arranged in described shell to be driven by described connecting shaft and rotates, described speed reducer and described motor are arranged on described base respectively, it is characterized in that: described rotor is provided with 2-10 sheet blade, the diameter of described rotor is 250-350mm, width is 200-600mm, Root diameter is 155 ± 20mm, the diameter of described axis hole is 110 ± 20mm.
The width being arranged on the described rotor in described shell is 226-320mm.
The width being arranged on the described rotor in described shell is 226mm.

Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is the structural representation of the utility model rotor.
Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
As shown in Figure 1-2, mark 1-7 in figure to be expressed as: motor 1, speed reducer 2, base 3, shell 4, rotor 5, blade 6, axis hole 7.
Embodiment: as shown in Figure 1, the large discharge rotor pump in the present embodiment comprises motor 1, speed reducer 2, base 3, shell 4, connecting shaft (not shown) and rotor 5, and wherein motor 1 forms to drive with speed reducer 2 as driving link and is connected.Speed reducer 2 is connected with forming between connecting shaft to drive, and motor 1 is connected by speed reducer 2 and drives connecting shaft to rotate.Connecting shaft is arranged on axis hole 7 inside that rotor 5 center position is offered.The periphery of rotor 5 is provided with some blades 6.When rotor 5 is rotated by connecting shaft drive, the some blades 6 being arranged on rotor 5 periphery rotate to carry fluid simultaneously.
In order under the prerequisite meeting economic benefit, make that the increased flow capacity of rotor pump, pressure raise, application area is wider, the physical dimension of rotor 5 is redesigned.Refer to meet economic benefit, when rotor 5 physical dimension strengthen or blade 6 increase time, the flow of rotor pump must strengthen, pressure must raise, but the relation between the physical dimension of rotor 5 and the flow of rotor pump, pressure is not linear relationship, simultaneously because the size of rotor 5 increases, when it rotates, required driving force also can increase, and the electric energy that motor 1 consumes is also just corresponding larger.Therefore, need what time to come to redesign the physical dimension of rotor 5 comprehensively.
In the present embodiment, as shown in Figure 2, the peripheral described rotor of rotor 5 is provided with 2-10 sheet blade 6, and the diameter D of rotor 5 is 250-350mm, and width B is 200-600mm, and Root diameter is 155 ± 20mm, and the diameter of axis hole 7 is 110 ± 20mm.
The present embodiment is in the specific implementation: adopt the rotor 5 of following four kinds of physical dimensions to meet and design needs.
The diameter that in table, diameter 305mm refers to four kinds of physical dimension rotors 5 is 305mm.Two kinds of width that width 226 and width 320mm refer to four kinds of physical dimension rotors 5 are respectively 226mm and 320mm.And the width being provided with rotor 5, two rotors 5 of two couplings in the shell 4 that width 452mm and width 640mm refers to wherein a kind of rotor pump is respectively 226mm, the output of two rotors 5 can be coupled into output that width is the rotor of 452mm; Same, the width that width 640mm refers in shell 4 rotor 5, two rotors 5 being provided with two couplings is respectively 320mm, the output of two rotors 5 can be coupled into output that width is the rotor of 640.
Although above embodiment elaborates the design of the utility model object and embodiment with reference to accompanying drawing, but those of ordinary skill in the art can recognize, under the precondition not departing from claim limited range, still various improvement and conversion can be made to the utility model, as: the structure of blade 6, form; The mounting structure etc. of connecting shaft, therefore do not repeat one by one at this.
