Abstract
The utility model relates to a water pump protection return circuit, it can protect the water pump comprehensively when taking place the pipeline jam in the water pump major loop. The utility model discloses an in the water pump protection return circuit in confined pipe-line system, the interface in water pump protection return circuit is connected respectively on the export of water pump and entry. Like this, even when the pipeline takes place to block up in the major loop for the water pump, liquid can participate in the circulation in the protection return circuit for the water pump obtains effectual protection.
Description
Technical field
The utility model relates to water pump.Be specifically related to the water pump protection loop in the using process of closing pipe line system.
Background technique
Existing water pump protection loop as shown in Figure 1, wherein the liquid circulation loop of water pump major loop is: liquid is by outlet 5 → pipeline F of inlet 4 → closing pipe line E of system of container outlet 1 → pipeline B → pump entrance 2 → water pump P → exit of pump 3 → pipeline C → threeway 7 → pipeline D → E of closing pipe line system (load) → flow back to container A (solid arrow direction in as Fig. 1) through container inlet 6.The liquid circulation loop in water pump protection loop is: liquid is by container outlet 1 → pipeline B → pump entrance 2 → water pump P → exit of pump 3 → pipeline C → threeway 7 → pipeline G → flow back to container A (dotted arrow direction in as Fig. 1) through another inlet 8 of container.
Above-mentioned water pump protection loop works principle is that when the pipeline blocking phenomenon took place for pipeline D, the E of closing pipe line system and pipeline F in the major loop, liquid circulated in the protection loop, thereby the certain protection effect is played in the running of water pump.But there is following shortcoming in this protection loop: if under the situation of pipeline B and C generation pipeline blockage in the major loop, liquid can not participate in circulation, and water pump can not be effectively protected.
The model utility content
At the problems referred to above, the utility model proposes the water pump protection loop that a kind ofly overcomes above-mentioned defective in the prior art, can the general protection water pump when in the water pump major loop, pipeline blockage taking place.
According to the utility model, a kind of water pump protection loop in the pipe-line system of sealing is provided, wherein the interface in water pump protection loop is connected in the outlet and inlet of water pump.
Like this, even when water pump pipeline in major loop take place to stop up, liquid can participate in circulation in the protection loop, make water pump be effectively protected.
Description of drawings
Fig. 1 is the schematic representation in existing water pump protection loop;
Fig. 2 is an embodiment's in the utility model water pump protection loop a schematic representation; And
Fig. 3 is another embodiment's in the utility model water pump protection loop a schematic representation.
Embodiment
Specifically describe the utility model water pump protection loop embodiment below in conjunction with accompanying drawing, wherein identical drawing reference numeral is represented identical parts.
Fig. 2 shows an embodiment in the utility model water pump protection loop.As shown in the figure; the liquid circulation loop of water pump major loop remains unchanged; but the interface that will protect the loop is installed near the water pump gateway; like this; when even water pump pipeline B in major loop take place to stop up, liquid is by water pump P outlet 3 → threeway 7 → pipeline G → flow back to water pump P (dotted arrow direction in as Fig. 2) through threeway 8, because liquid participates in circulation in the protection loop; make water pump be effectively protected, and such protection loop is more reasonable on cost.
Fig. 3 shows another embodiment in the utility model water pump protection loop.For the protection loop is installed in practice more easily; in Fig. 2, distinguish connecting pipeline C and H between the interface in protection loop and the water pump gateway; like this; when water pump pipeline B in major loop take place to stop up, liquid flowed back to water pump P (as dotted arrow direction among Fig. 3) by water pump P outlet 3 → pipeline C → threeway 7 → pipeline G → threeway 8 → by the road H.
And the pipeline sectional area in above-mentioned protection loop should design according to the permission minimum discharge and the major loop rated flow of water pump when fluid circulation system designs.
The novel occasion that is applicable to that mainly water pump uses in the pipe-line system of sealing of this use.
Although the utility model is described, foregoing description is that the utility model is not limited to above-mentioned specific descriptions in conjunction with the accompanying drawings for illustrative purposes.Those of ordinary skills can carry out various changes and not break away from spirit of the present utility model it, and protection domain of the present utility model is limited by the accompanying Claim book.
Claims (4)
1. the water pump protection loop in the pipe-line system of sealing is characterized in that the interface in water pump protection loop is connected in the outlet and inlet of water pump.
2. water pump protection according to claim 1 loop, wherein said protection loop is connected in the outlet and inlet of water pump by threeway respectively.
3. water pump according to claim 2 protection loop wherein also is being respectively equipped with pipeline between the outlet of water pump and the described threeway and between the inlet of water pump and another described threeway.
4. according to each described water pump protection loop among the claim 1-3, the pipeline sectional area in wherein said pipeline protection loop is according to the permission minimum discharge and the design of major loop rated flow of water pump.
