Description
Technical field
The utility model belongs to the environmental protection equipment technical field, relates in particular to a kind of high-voltage energy-saving pump.
Background technique
At present, high-pressure service pump mainly comprises the parts such as power end and fluid end, power end comprises prime mover and plunger, the mechanical energy of prime mover is passed to the to-and-fro motion that realizes plunger on the plunger, and fluid end constantly realizes sucking, discharging water according to the to-and-fro motion of plunger, thereby the mechanical energy of plunger is converted to the pressure energy of water, and is injected into the destination by high pressure pipe line.
But above-mentioned power end energy comes from the energy that prime mover provides fully, and its consumption is larger, and input cost is higher.
The model utility content
The purpose of this utility model is to provide a kind of high-voltage energy-saving pump, and the high pressure pump power end energy that being intended to solve prior art provides comes from the energy that prime mover provides fully, and its consumption is larger, the problem that input cost is higher.
The utility model is to realize like this, a kind of high-voltage energy-saving pump, described high-voltage energy-saving pump is provided with the pump housing, be provided with low-pressure cavity and hyperbaric chamber in the described pump housing, the described pump housing is provided with the liquid entering hole that communicates with described low-pressure cavity, the opening of described low-pressure cavity is provided with plunger cavity, be provided with stage columnar plug in the described plunger cavity, one end of described stage columnar plug stretches in the described low-pressure cavity, described hyperbaric chamber is communicated with a drainage pipe, the other end of described drainage pipe is communicated with described plunger cavity, the inwall of described plunger cavity is provided with flow guide device, have the groove that is communicated with described drainage pipe on the outer circumferential face of described flow guide device, have a plurality of pod apertures that run through described flow guide device in the described groove.
In the utility model, what the plunger in the plunger cavity adopted is stage columnar plug, simultaneously drainage pipe with the fraction highly pressurised liquid drainage in the hyperbaric chamber to plunger cavity, thereby utilize highly pressurised liquid that the ladder end face of stage columnar plug is produced certain pressure, thereby for power end provides significant energy source, make the energy of power end be fixed against prime mover no longer fully, reduced the energy consumption of prime mover, reduced the cost input.
Description of drawings
Fig. 1 is the high-voltage energy-saving pump structure schematic diagram that the utility model provides.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the utility model.
Fig. 1 shows the high-voltage energy-saving pump structure schematic diagram that the utility model provides, and for convenience of explanation, has only provided the part relevant with the utility model among the figure.
The high-voltage energy-saving pump that the utility model provides is provided with the pump housing 1, be provided with low-pressure cavity 11 and hyperbaric chamber 12 in the described pump housing 1, the described pump housing 1 is provided with the liquid entering hole 13 that communicates with described low-pressure cavity 11, the opening of described low-pressure cavity 11 is provided with plunger cavity 2, be provided with stage columnar plug 21 in the described plunger cavity 2, one end of described stage columnar plug 21 stretches in the described low-pressure cavity 11, described hyperbaric chamber 12 is communicated with a drainage pipe 3, the other end of described drainage pipe 3 is communicated with described plunger cavity 2, the inwall of described plunger cavity 2 is provided with flow guide device 4, have the groove (not shown) that is communicated with described drainage pipe 4 on the outer circumferential face of described flow guide device 4, have a plurality of pod apertures (not shown)s that run through described flow guide device 4 in the described groove.
In the utility model, on the pump housing 1 that high-voltage energy-saving jumps the parts such as power end and fluid end are installed also, wherein, power end can be converted to the mechanical energy of prime mover the straight reciprocating motion of plunger, and fluid end can be converted to the straight reciprocating motion of plunger the pressure energy of liquid, certainly, only provided the component relevant with the utility model among the figure, and not completely shown its concrete structure.
In the utility model, prime mover drives stage columnar plug to left movement, produces negative pressure in the low-pressure cavity, and under the effect of this negative pressure, liquid is in liquid entering hole enters into low-pressure cavity; Prime mover drives stage columnar plug and moves right, and the liquid in the low-pressure cavity enters in the hyperbaric chamber under the impetus of stage columnar plug; In this process, highly pressurised liquid has the sub-fraction highly pressurised liquid in drainage pipe enters into groove, enter in the plunger cavity by a plurality of water conservancy diversion through holes again, in limited plunger cavity space, this part highly pressurised liquid acts on the ladder end of stage columnar plug, stage columnar plug is moved right can play certain impetus, thereby played the effect of assist prime mover, save the Partial Power of prime mover, reduced the cost input.Through practical proof, this energy-saving high pressure water-injection pump energy-saving efficiency reaches 18%, and power of motor 110KW does not compare when energy-conservation, day economize on electricity 480KW, and year power saving accumulative total reaches 172800KWh.
This energy-saving high pressure water-injection pump is simple in structure, by the cooperate input that can effectively reduce cost of stage columnar plug with the drainage pipeline, saves power of motor, has good practicability.
In the utility model, what the plunger in the plunger cavity adopted is stage columnar plug, simultaneously drainage pipe with the fraction highly pressurised liquid drainage in the hyperbaric chamber to plunger cavity, thereby utilize highly pressurised liquid that the ladder end face of stage columnar plug is produced certain pressure, thereby for power end provides significant energy source, make the energy of power end be fixed against prime mover no longer fully, reduced the energy consumption of prime mover, reduced the cost input.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
