Abstract
The utility model relates to a fluid pumping device, which comprises a pump, a negative pressure tank and a pipeline. A storage tank is further added on the negative pressure tank, and the negative tank is communicated with the storage tank through a pipeline. The fluid pumping device is simple and reliable in structure, and more effectively overcomes the shortage that air is pumped into the device after the device is stopped.
Description
Technical field
The utility model relates to a kind of fluid pumping apparatus.
Background technique
The general pumping fluid lower than pump position all adds basket strainer in the bottom of pipeline usually.When basket strainer was not closed completely, in a single day pump stops will have air in its body, and restarting must water or pulling vacuum, pretty troublesome.
Summary of the invention
The purpose of this utility model just provide a kind of when pump restarts, do not need water or pulling vacuum fluid pumping apparatus.
Major technique of the present utility model is as follows:
A kind of fluid pumping apparatus, it comprises pump, negative-pressure cup and pipeline, wherein adds a storage tank on negative-pressure cup again, negative-pressure cup is communicated with storage tank by pipeline.
The utlity model has simple and reliable for structurely, can preferably resolve and shut down the disadvantage that the back pump advances air.
Description of drawings
Fig. 1 is the structural representation of model utility.
Wherein: 1,2,3,4 pipelines 5, basket strainer C, pump A, negative-pressure cup B, storage tank
Embodiment
As shown in the figure, fluid pumping apparatus, it comprises pipeline 1,2,3,4, pump C, negative-pressure cup A, storage tank B.Storage tank B is full of by fluid in the time of normal boot-strap; fluid when shutting down in the storage tank B will replenish the fluid that is not closed completely and loses because of basket strainer 5 by managing 2,3 backspace negative-pressure cup A; pump C is full of by fluid all the time, just needn't water or pulling vacuum when starting shooting again.
Claims (1)
1. fluid pumping apparatus, it comprises pump, negative-pressure cup and pipeline, it is characterized in that: add a storage tank B on negative-pressure cup A again, negative-pressure cup is communicated with storage tank by pipeline.
