Description
Technical field
The utility model relates to pumping device, particularly relates to the vapour-pressure type pumping device that a kind of structure is simple, cost is low, convenient to use.
Background technology
Casting industry inevitably uses alcohol in whole production process, coating and antirust wet goods barreled liquid, traditional liquid mode of getting generally direct inclination metal bucket gets use, also the pumping plant of the similar pumped well of lift pump or the hand using price comparison high is had, lift pump is applicable to drawing liquid in enormous quantities, but the general volume of equipment is larger, mobile inconvenience and comparatively occupied ground, operation and maintenance require higher, expense is large, hand pumping plant is applicable to small lot drawing liquid, main by manpower driving, get the work capacitys such as the alcohol paint of needed for work one day very large, and special messenger must be sent to be responsible for, human cost increases.
Summary of the invention
The utility model mainly provides that a kind of structure is simple, low cost of manufacture, convenient to use, time saving and energy saving vapour-pressure type pumping device, solve the pumping device manufacturing cost existed in prior art high, get the technical matters that liquid operation wastes time and energy etc.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of vapour-pressure type pumping device, comprise the bung of airtight sealing cover on liquid receiver, described bung is plugged with and extends to ventilation flue in liquid receiver and catheter, and under being positioned at liquid level corresponding to the catheter tip in liquid receiver, to one end of then spring tube on the catheter that liquid receiver is outer corresponding, to then Air compressor on the outer corresponding ventilation flue of liquid receiver.The gas resource that the Air compressor utilizing casting industry to have produces, Air compressor is connected on the external side end of ventilation flue, in liquid receiver, pressurized air is squeezed into during use, airtight liquid receiver is made to produce external and internal pressure poor, thus the liquid in liquid receiver is flowed out from catheter, and be delivered in small container by spring tube, meet and dailyly required get liquid requirement, structure is simple, low cost of manufacture, convenient to use, time saving and energy saving.
As preferably, the outer corresponding catheter of described liquid receiver and ventilation flue are respectively equipped with shutoff valve.Can close or open catheter or ventilation flue at any time by shutoff valve, easy to use.
As preferably, be provided with gap bottom the catheter tip in described liquid receiver and liquid receiver, the ventilation flue end in liquid receiver is mutually concordant with bung lower surface.When being provided with gap bottom catheter tip and liquid receiver, can guarantee that the liquid in liquid receiver can extrude smoothly; Bubble is produced when avoiding suppressing in liquid receiver when ventilation flue end is mutually concordant with bung lower surface.
As more preferably, described catheter tip and liquid receiver bottom gap are 5mm to 15mm.Rational gap can be guaranteed that the hydraulic pressure in liquid receiver is suitable and be defeated out, ensures that again the residual liquid quantity that cannot extrude in liquid receiver is minimum.
As preferably, described spring tube is Rubber Parts.Rubber Parts cost is low, good springiness, easy to use and connection.
Therefore, vapour-pressure type pumping device of the present utility model has following advantage: utilize assembling parts simple and with low cost to form, reduce manufacturing cost, convenient and swift during use, workable, transport easy to carry, has saved material resources and human cost.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of vapour-pressure type pumping device of the utility model.
Detailed description of the invention:
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of vapour-pressure type pumping device of the present utility model, comprise the bung 1 of the circle of airtight sealing cover on liquid receiver, bung 1 is vertically interspersed with and extends to ventilation flue 2 in liquid receiver and catheter 3, ventilation flue 2 and keep between catheter 3 and bung 1 sealing, under being positioned at liquid level corresponding to catheter 3 end in liquid receiver and with liquid receiver bottom keep the distance of 10mm, ventilation flue 2 end in liquid receiver is mutually concordant with bung 1 lower surface, to one end of then spring tube 4 on the catheter 3 that liquid receiver is outer corresponding, spring tube 4 is quality of rubber materials, to then Air compressor 5 on the ventilation flue 2 that liquid receiver is outer corresponding, for the ease of using, the outer corresponding catheter 3 of liquid receiver and ventilation flue 2 have also installed a shutoff valve 6 respectively.
Specific embodiment described herein is only to design of the present utility model explanation for example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
