Description
Technical field
The utility model belongs to mechanical device field, specifically a kind of high pressure, large discharge plunger reciprocating pump.
Background technique
At present, conventional plunger is made primarily of common cast iron, in order to strengthen corrosion resistance, needs plate layer of metal chromium at its outer surface.Because plunger reciprocates is frequent, wear and tear very large.After long-time use, sealing place of its plunger just there will be the situation of leakage, and serious its liquid carried that also can make is polluted, and impact is produced.In addition, in movement process, transmission is steady not, and noise is also larger, and greasy property is also good not.
Model utility content
The purpose of this utility model solves deficiency of the prior art, provides a kind of high pressure, large discharge plunger reciprocating pump.
The utility model comprises fluid end and power end, and described fluid end is connected with stud with power end by acorn nut, and described power end is provided with housing structure.
Preferably, described stud is run through power end and is fixedly connected with by acorn nut with fluid end.
Preferably, power end is provided with reducing gear, and described reducing gear adopts two herringbone tooth to slow down.
Preferably, described fluid end adopts split type feed pathway structural design.
Preferably, described fluid end is provided with pump head
The utility model is a kind of high pressure, large discharge plunger reciprocating pump, has that compact structure, volume are little, lightweight, efficiency high.In addition, the utility model manufacture cost is not high, and structure is simple, and practical, the utility model is adapted at correlative technology field and applies.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below with reference to accompanying drawings the utility model is described in more detail, which show preferred embodiment of the present utility model, should be appreciated that those skilled in the art can revise the utility model described here and still realize advantageous effects of the present utility model.Therefore, following description is appreciated that extensively knowing for those skilled in the art, and not as to restriction of the present utility model.
In order to clear, whole features of practical embodiments are not described.They in the following description, are not described in detail known function and structure, because can make the utility model chaotic due to unnecessary details.Will be understood that in the exploitation of any practical embodiments, a large amount of implementation detail must be made to realize the specific objective of developer, such as, according to regarding system or the restriction about business, change into another embodiment by an embodiment.In addition, will be understood that this development may be complicated and time-consuming, but be only routine work to those skilled in the art.
For making the purpose of this utility model, feature becomes apparent, and is further described embodiment of the present utility model below in conjunction with accompanying drawing.It should be noted that, accompanying drawing all adopts the form that simplifies very much and all uses non-ratio accurately, only in order to object that is convenient, aid illustration the utility model embodiment lucidly.
As shown in Figure 1, the utility model is a rated power is 450kW, and rated pressure is 20M Pa, and rated flow is high pressure, the large discharge plunger reciprocating pump of 1120l/m.The utility model comprises fluid end 1 and power end 2, and described fluid end 1 is connected with stud with power end by acorn nut, and described power end 2 is provided with casing 3 structure.
Stud of the present utility model is run through power end 2 and is fixedly connected with by acorn nut with fluid end 1.
The utility model power end 2 is provided with reducing gear, and described reducing gear adopts two herringbone tooth to slow down.This structural design ensure that transmission is more steady reliably, noise is little, improves greasy property, is applicable to long-time continuous and runs.
Fluid end 1 of the present utility model adopts split type feed pathway structural design, increases feed liquor aperture, alleviates pump housing weight.
Fluid end 1 of the present utility model is provided with its reasonable in design of pump head 4 and is convenient to safeguard, changing easily damaged parts does not need to dismantle pump head.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model embodiment.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from the spirit or scope of the utility model embodiment, can realize in other embodiments.Therefore, the utility model embodiment can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
These are only the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; within all spirit in the utility model embodiment and principle; any amendment of doing, equivalent replacement, improvement etc., within the protection domain that all should be included in the utility model embodiment.
