Abstract
A novel roto-jet pump comprises a pump body, a rotor cavity, a collector tube, an impeller, an inlet pipe and an outlet pipe. The end of the pump body is provided with a pump cover. The rotary rotor cavity is arranged inside the pump body. The inlet pipe is disposed outside the pump cover and the outlet pipe is arranged at the center of the pump cover. The fixed collector tube is disposed inside the rotor cavity and is vertically connected with the outlet pipe. The beneficial effects of the utility model are that not many components are arranged in the pump body; when the pump is working, liquid enters the rotary rotor cavity via the inlet pipe and enters the collector tube under the influence of centrifugal force and pressure, and speed energy is converted into stable pressure energy with no fluctuation via the collector tube and discharges from the outlet pipe; a novel structure with low cantilever ratio is employed by the rotor cavity so that support is stable and reliable, and unstable support caused by an overweight conventional rotor and a large cantilever is avoided; and the novel roto-jet pump has the advantages of convenient dismounting and maintenance, low cost, prolonged service life of parts, simple operation, improvement of work efficiency, etc.
Description
Technical field
The utility model relates to high pressure chemical pump technology, relates in particular to a kind of novel rotary-jet pump.
Background technique
Rotary-jet pump is based on a kind of novel high-pressure chemical pump of Pitot tube principle rotary-jet pump model, just need this high-pressure service pump as cleaning system in the food service industry, be a kind of small flow, high-lift, structure and all very unique single-stage pump of working principle, belong to utmost point low specific speed pump, the principle of punching press stagnation supercharging in conventional centrifugal pump and the space technology is adopted in its design.Existing rotary-jet pump is bad at as liquid or the solids-laden fluid of carrying cleaning, need improve with better solution and be applied to cavitation erosion and the pressure decline problem that multistage centrifugal pump that boiler feed water, boiler blow-down water reclaim exists.In addition, rotary-jet pump can be used as the standard configuration equipment of chemical plant deep-well waste disposal field, food processing CIP high-pressure wash system, manufacturing industry workshop purging system and paper industry high-pressure wash.In sum, its structure of rotary-jet pump should be comparatively simple, if volume is excessive or complicatedly all can bring certain difficulty to maintenance, in addition, the cavitation resistive property of a lot of pump housings is relatively poor, and its flow, pressure, rotating speed are stable inadequately.
The model utility content
At above defective, the purpose of this utility model provides and a kind ofly simplifies the structure, rotor supports is steadily reliable, easy to operate, help the novel rotary-jet pump of raising the efficiency, increasing the service life, to solve many deficiencies of prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of novel rotary-jet pump, comprise the pump housing, rotor cavity, liquid collecting pipe, impeller, inlet tube and outer pipe, body end is provided with pump cover, the rotor rotated cavity is equipped with in described pump housing inside, the external side of rotor chamber is provided with impeller, an inlet tube is offered in the described pump cover outside, and an outer pipe is offered in the pump cover center portion, and described rotor inside cavity is provided with fixing liquid collecting pipe and is connected with outer pipe is vertical.
The beneficial effect of novel rotary-jet pump described in the utility model is: simplified agent structure, pump housing component are less, be in the pump only two groundwork parts be a rotor rotated and a fixing liquid collecting pipe, working as liquid during work enters in the rotor rotated chamber from inlet tube, enter liquid collecting pipe under centrifugal force and pressure effect, by liquid collecting pipe speed can be converted into steady, pulseless pressure can discharge from outer pipe; The rotor cavity adopts cantilever than little new structure, supports steadily reliably, and it is overweight and cantilever is excessive and support jiggly deficiency to have overcome conventional rotors; In addition, also have dismounting and easy to maintenance, reduced cost, prolonged parts working life, simple to operate, characteristics such as help increasing work efficiency.
