Abstract
Provided is a gas-liquid two-phase flow pump capable of refining and equalizing air bubble particles deeply. The gas-liquid two-phase flow pump capable of refining and equalizing the air bubble particles deeply is an improvement on a traditional peripheral pump, and is characterized in that a water diversion outlet hole is formed in an output port of a peripheral pump, a water diversion inlet hole is formed in a pump body, and a communicating pipe between the two round holes is used for connecting a magnetic valve in a series mode. The magnetic valve can be opened or closed in a certain period, and therefore two-phase flow continuously output from the output port is changed into impulse type output and flows back into the pump body, the two-phase flow by 10%-20% of total flow can be led out from the output shaft and returns into the pump body, pump pressure can be alternated continually, and motion change of fluid and impellers in the pump is large. Thus, crashing effects of the impellers are enhanced greatly, gas-liquid two-phase flow air bubble particles at the outlet port are even, and differences of the gas-liquid two-phase flow air bubble particles are reduced greatly.
Description
Technical field
But the present invention relates to the gas-liquid two-phase flow pump of a kind of degree of depth refinement and even bubble particles, be specially employing and make the two phase flow continuous wave output become the pulsed output intent, make the two phase flow bubble particles even, significantly dwindle, belong to fluid pump class conveying equipment technical field.
Background technique
Peripheral pump is one of fluid class material conveying equipment that extensively adopts, it is to make liquid produce the effect of vorticla motion and suck and discharge liquid when leaning on vane rotary, the specific speed of peripheral pump is usually between 6～50, it is a kind of pump of low-flow high-lift, suitable transport viscosity is little, without solid particle, pure liquid or gas-liquid mixture, the flow of general peripheral pump is 0.18～45m
3/ h, single-stage lift can reach about 250m.Peripheral pump is compared with the centrifugal pump of same performance, have the advantages such as volume is little, lightweight, simple in structure, cost is low, because most of peripheral pumps all have suction capacity, so peripheral pump can also be bled or the conveying gas liquid mixture, this is the not available feature of general centrifugal pump.
Known peripheral pump is when the conveying gas liquid mixture, the bubble particles that produces is large and very inhomogeneous, Chinese invention patent " adjustable flow peripheral pump " (application number: 03130472.9 applying date: 2003-07-28) disclosed be peripheral pump install its water inlet and osculum respectively with the water outlet of peripheral pump and water intake is connected and this water inlet and osculum also can be interconnected or block flow regulator; Utility model patent " complex intensifying aerator " (application number: the 89208037.X applying date: be to adopt pressurized air is added respectively gas-liquid two-phase flow pump input end and output terminal 1989-05-27), reach the abundant mixed effect of gas-liquid.In existing patent or the document, have no traditional peripheral pump is improved, make it when carrying gas-liquid two-phase flow, but degree of depth bubble disintegration particle and homogenizing method make the two phase flow bubble particles even, significantly dwindle.
Summary of the invention
The objective of the invention is to ask a question for background technique, but the gas-liquid two-phase flow pump of a kind of degree of depth refinement and even bubble particles is provided, make the two phase flow bubble particles even, significantly dwindle.
Technological scheme of the present invention is: but the gas-liquid two-phase flow pump of a kind of degree of depth refinement and even bubble particles, it is the improvement to traditional peripheral pump, it is characterized in that: have minute water at the delivery outlet of peripheral pump and portal, have a minute water hand-hole on the pump housing, between two circular holes with connecting tube being connected in series solenoid valve.Its working principle and beneficial effect are: described solenoid valve can open or close by certain cycle, make from the two phase flow of delivery outlet continuous wave output and become pulsed output and be back in the pump housing, can draw 10%～20% of total discharge from delivery outlet is back in the pump housing, make constantly alternation of pump pressure, the relative movement of pump inner fluid and impeller changes greatly, thereby the pulverization of impeller is greatly strengthened, and the gas-liquid two-phase flow bubble particles of delivery outlet is even, significantly dwindles.
But the gas-liquid two-phase flow pump of aforesaid a kind of degree of depth refinement and even bubble particles, it is characterized in that: minute water goes out bore dia and enters bore dia greater than minute water, the circular hole internal diameter that divides water to portal is 1/2～1/5 of delivery outlet internal diameter, minute water hand-hole is opened the circular hole internal diameter by dividing the water circular hole internal diameter 1/2～3/4 that portals out, and the switch periods of solenoid valve is 0.5～5 second.Its beneficial effect is: enter bore dia because minute water goes out bore dia greater than minute water, draw back two phase flow in the pump housing and be the interrupted mode with jet, inject on the impeller of High Rotation Speed in the pump, make to produce vigorous agitation in the pump housing, reach degree of depth refinement and even bubble particles effect.
Description of drawings
Accompanying drawing 1 is embodiment of the invention gas-liquid two-phase flow pump stereogram;
Accompanying drawing 2 is embodiment of the invention gas-liquid two-phase flow pump work schematic diagram.
Embodiment
Mark in the accompanying drawing: in the accompanying drawing 1: A-suction port, B-suction port, C-delivery outlet, D-minute water portals, E-minute water hand-hole; In the accompanying drawing 2: F-solenoid valve.
Below in conjunction with accompanying drawing inventive embodiments is described further:
Shown in accompanying drawing 1, accompanying drawing 2, but the gas-liquid two-phase flow pump of a kind of degree of depth refinement and even bubble particles, open two circular holes on the basis of traditional peripheral pump and access solenoid valve F, one of them circular hole D opens on the peripheral pump delivery outlet, another circular hole E opens on the pump housing, minute water D internal diameter that portals is 1/2～1/5 of delivery outlet C internal diameter, minute water hand-hole E internal diameter is minute water 1/2～3/4 of the D internal diameter that portals, minute water portals on D and minute water hand-hole E, be connected to respectively connecting tube, the other end of two connecting tube links to each other with the input/output terminal of solenoid valve F respectively.
The working procedure of the embodiment of the invention is as follows: by solenoid valve F periodic switch, can draw 10%～20% of total discharge from delivery outlet C is back in the pump housing, owing at the pipeline that refluxes a solenoid valve F is installed, and with 0.5～5 second cycle switch, such as: if switch periods is 1 second, then opened in the 1st second, closed, opened in the 3rd second in the 2nd second .....That pulse mode enters the pump housing with the two phase flow that reaches backflow.On the other hand because minute water portals the pressure of D place two phase flow much larger than suction port A place pressure, draw back two phase flow in the pump housing and be the interrupted mode with jet, inject on the impeller of High Rotation Speed in the pump, make and produce vigorous agitation in the pump housing, so that the two phase flow gas-liquid degree of depth in the pump housing is mixed, fragmentation, form uniform particles, tiny two-phase fluid, flowed out by delivery outlet C, utilize this method can make the two phase flow bubble particles of outflow even, significantly dwindle.
