Description
Technical field
The utility model relates to chemical industry, thermal technology, mechanical-hydraulic technical field, is specifically related to a kind of container and fills row's circulation means.
Background technique
In the mechanical-hydraulic technical field, hydraulic container is filled row's circulation uses following dual mode always:
(1) uses two pumps container is accomplished charging into and discharge work of liquid respectively.
(2) use one to have pump the charging into and discharge work that charges into discharge function to container completion liquid.
For above-mentioned (1) mode: the shortcoming of existence and deficiency are that cost is high, and volume is big.
For above-mentioned (2) mode: the shortcoming of existence and the deficiency cost height that is to cost an arm and a leg, motor needs frequent start-stop and switching-over.
Frequent change pump drive motor working state more can not be ignored the influence of the impact of power network fluctuation, circuit elements device for powerful pump.Costco Wholesale is often restricting the economic profit of enterprise.
The model utility content
The utility model has overcome that existing cost is high to need the deficiency of frequent start-stop, switching-over with motor, provides a kind of cost container low and need not the frequent start-stop motor to fill row's circulation means.
For solving above-mentioned technical problem, the utility model adopts following technological scheme:
A kind of container fills row's circulation means; Comprise first liquid-container, second liquid-container; Be connected with first selector valve and second selector valve between said first liquid-container and second liquid-container; Be connected with pump between said first selector valve and second selector valve, said first selector valve also is communicated with second liquid-container through first pipeline, and said second selector valve also is communicated with first liquid-container through second pipeline.
In order to realize the utility model better, further technological scheme is:
As preferably: the first above-mentioned selector valve and second selector valve all are two position three-way valve.
As preferably: above-mentioned pump is a single pump.
The utility model can also be:
Above-mentioned pump is a kind of in centrifugal pump, gear pump, vane pump, volute pump, the plunger pump.
Compared with prior art, the beneficial effect of the utility model is:
(1) the utility model technological scheme only need use the logical single pump of a Daepori and two two position three-way valves can reach or realize that change passes in and out the purpose of the flow direction of container, and is simple in structure;
(2) need not use expensive double fluid to accomplish the flow direction that passes in and out container, effectively reduce installation cost to pump;
(3) need not use the logical single pump of two Daeporis to accomplish the flow direction of turnover container, reduce installation cost, save the space;
(4) need not change the sense of rotation of pump drive motor, need not the circuit of motor commutation;
(5) do not need frequent start-stop and change motor sense of rotation, avoid causing the surge, particularly heavy-duty motor of fluctuation and circuit elements device to influence bigger to electrical network because of the frequent electric machine operation state that changes;
This structure is in zero load starting state when (6) can make the electrical power running;
(7) this structure not only is suitable for the applications of small flow, small-power pump, and is more suitable in the applications of the high-power pump of big flow;
(8) this container fills that row's circulation means fills, to arrange process efficiency better;
(9) this structure contains fault-toleranr technique, and promptly no matter unnecessary combination of actions appears in two two position three-way valve logical action of this device, can not cause the superpressure damage accident of pump.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, the pairing name of the reference character in the accompanying drawing is called:
1-first liquid-container, 2-first selector valve, 3-pump, 4-second selector valve, 5-first pipeline, 6-second liquid-container, 7-second pipeline.
Embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the mode of execution of the utility model is not limited thereto.
As shown in Figure 1; A kind of container fills row's circulation means; Comprise first liquid-container, 1 second liquid-container 6, be connected with first selector valve 2 and second selector valve 4 between said first liquid-container 1 and second liquid-container 6, be connected with pump 3 between said first selector valve 2 and second selector valve 4; Said first selector valve 2 also is communicated with second liquid-container 6 through first pipeline 5, and said second selector valve 4 also is communicated with first liquid-container 1 through second pipeline 7.
The first above-mentioned selector valve 2 and second selector valve 4 all are two position three-way valve.
Above-mentioned pump is a single pump.
Above-mentioned pump 3 is a centrifugal pump, and when being a kind of in gear pump, vane pump, volute pump, the plunger pump, other structure Placement is constant, then enumerates embodiment no longer separately and describes.
In the face of filling the workflow of arranging circulation means, said vesse specifically describes down:
A. the zero load startups running of pump 3: only primer pump 3 runnings, liquid is got back to the suction port of pump 3 through second pipeline 7, gets from the exhaust port of pump 3 again, so moves in circles.
B. second liquid-container 6 being carried out liquid charges into: primer pump 3, startup second selector valve (4), can realize liquid in first liquid-container 1 is charged into the action of second liquid-container 6.
C. to the discharge of liquid in second liquid-container 6: primer pump 3, start first selector valve (2); Can realize the flow of liquid in second liquid-container 6 is got into pump 3 suction ports through first pipeline 5, second pipeline 7 of after pump 3 is got, flowing through is again got back in first liquid-container 1.
D. second liquid-container 6 filled, arranges action continuously: under the condition of pump 3 runnings, only need alternately change the valve position state of two selector valves, can realize second liquid-container 6 is carried out the continuous action of filling, arrange.
