Description
Technical field
The utility model relates to a kind of many plunger types high pressure reciprocating pump, relates in particular to the drive mechanism of this many plunger types high pressure reciprocating pump.
Background technique
Many plunger types high pressure reciprocating pump is widely used in each field such as oil, rock gas, chemical industry, metallurgy, coal, electric power, national defence, space flight as a kind of equipment of carrying highly pressurised liquid, and its discharge maximum pressure can reach 258MPa.
The structure of many plunger types high pressure reciprocating pump can be divided into driving end and fluid end, and the driving end of existing many plunger types high pressure reciprocating pump mainly contains two and turns crank mechanism form, three-throw crankshaft mechanism form, four-throw cankshaft mechanism form etc.All there is a common characteristic in the driving mechanism of these forms, and promptly each fluid end is in one line at grade.The driving mechanism of many plunger types high pressure reciprocating pump receives the restriction of inner mulit-turning crankshaft structure, makes so many plunger types high pressure reciprocating pump promptly to insert the output terminal of motor from the side input power of cabinet.
Mulit-turning crankshaft of the prior art as shown in Figure 1, each crank pin of this mulit-turning crankshaft is around misalignment and annular arrangement.The pump head that uses this many plunger types of mulit-turning crankshaft high pressure reciprocating pump must be to be arranged side by side, and Here it is causes the size of pump head can not be excessive, because the distance between the adjacent pump head is directly proportional with distance between crank pin adjacent on the centerline direction.So the size of pump head is done greatly, just must change the mulit-turning crankshaft of corresponding size.The crank pin number of this mulit-turning crankshaft is many more, and its difficulty of processing is just big more.This is because crank pin distributes to satisfy to be centered around around the center line, satisfies again in dislocation requirement separately on centerline direction.Therefore, the mulit-turning crankshaft difficulty of processing this structure is very high, and processing is wasted time and energy.
Be used to hold the perforate that power is imported because the power input mode has determined cabinet one side of many plunger types high pressure reciprocating pump to be provided with, occur oil leakage phenomenon through regular meeting at tapping during actual the use.The reason that causes this defective is to account for the oiling agent in cabinet inside 2/3rds spaces because the work of many plunger types high pressure reciprocating pump the time must be packed at cabinet inside; Simultaneously, mulit-turning crankshaft is in horizontal working state, make the inner space of cabinet be provided with and trend towards flat structure, and then the liquid level of oiling agent did not have at tapping, occurs oil leakage phenomenon after the use.
In sum, many plunger types high pressure reciprocating pump of the prior art adopts horizontal working method and dependency structure, has that the pump head size is little, the production and processing difficulty is big, the shortcoming of poor sealing performance.
Summary of the invention
The technical problem that the utility model will solve provides a kind of many plunger types high pressure reciprocating pump of simple in structure, convenient for production, upright work that sealability is strong.
For solving the problems of the technologies described above; The utility model adopts following technological scheme: this many plunger types high pressure reciprocating pump comprises cabinet, motor, speed reducer, connecting body and pump head, and said motor via reducer is installed on the cabinet, and said pump head is connected on the cabinet through connecting body; Said motor is positioned at the top of casing; At least be provided with three connecting bodys on the said cabinet, said connecting body circular array is at the casing sidepiece and be the state that staggers up and down, all is provided with pump head on each connecting body; Said box house also is provided with one-throw crankshaft mechanism; Said one-throw crankshaft mechanism comprises an one-throw crankshaft and three reciprocal transmitting assembliess at least, and three reciprocal transmitting assembliess all flexibly connect with one-throw crankshaft, and three reciprocal transmitting assembliess are movably connected in the connecting body respectively.
Each pump head span of many plunger types high pressure reciprocating pump of the utility model is very big, and does not receive the structure influence of crank mechanism, so the pump head size can be sufficiently large.One-throw crankshaft vertically is installed in box house, and the perforate that is used to insert power like this on the casing just can place the casing top, and then avoids oil leakage phenomenon; And this one-throw crankshaft has only a crank pin, therefore manufactures difficulty and obviously reduces.
Preferred as the utility model; Said reciprocal transmitting assemblies comprises connecting rod, slide bar, plunger at least; Said one-throw crankshaft one end is movably connected in box house, and the other end is connected with the output terminal of speed reducer, and said connecting rod one end and one-throw crankshaft flexibly connect; One end of the other end and connecting rod flexibly connects, and the other end of said connecting rod is connected with plunger.The reciprocal transmitting assemblies of this structure has characteristics simple in structure, that transmission efficiency is high, in the to-and-fro motion system, has the high characteristic that adapts to of stability.
Preferred as the utility model; The crank pin diameter of said one-throw crankshaft is greater than axle body; The link position of said axle body and crank pin departs from the position of center line of crank pin, and said crank pin surface is provided with three road parallel annular grooves at least, and said connecting rod is movably connected in the groove.Large-sized crank pin structure has the big characteristics of surface area, when the mutual friction of connected components phase, can reduce friction like this through the mode that reduces pressure, so that the wear resistance of lifting feature, the working life of prolongation parts.
The utility model adopts technique scheme: this many plunger types high pressure reciprocating pump uses one-throw crankshaft to drive the reciprocal transmitting assemblies of annular distribution through improving crankshaft structure, so make pump head can annular distribution in the casing avris, increased the pump head spacing.One-throw crankshaft vertically is placed in the casing, forms the mode of upright work, and the setting of casing opening is optimized, and reaches and utilizes the casing intact part to hold oiling agent, thereby effectively improve the sealability of the whole pump housing.The one-throw crankshaft technology of the many plunger types high pressure reciprocating pump employing that should uprightly work; Not only well solved the size-constrained problem with leakage of oil of pump head; And self structure has the characteristics of simple rigid; Be easy to processing, therefore to product up-gradation, reduce production costs, guarantee that quality of product is significant.
