Abstract
The utility model discloses a plunger pump comprising a piston box body and a connecting rod plunger assembly performing reciprocating movement in the piston box body. The central line of the piston box body is vertical and the connecting rod plunger assembly performs the reciprocating movement in the piston box body in the vertical direction. The plunger pump employs a manner of being exposed out of the ground and fixed on a pedestal vertically and realizes reduction of reciprocating friction by 30% compared with plunger pumps employing a conventional horizontal manner and a conventional V-shaped arrangement manner, so that the continuous operation time of the plunger pump is increased, the service lifetime of the plunger pump is prolonged by 30%, and the cost of a user is reduced. The plunger pump is suitable for drainage and is especially applicable to muddy water.
Description
Technical field
The utility model relates to hydraulic pressure installation, relates in particular to a kind of plunger pump.
Background technique
Plunger pump is with its compact structure at present, the working pressure high is used widely in market, for the plunger pump of larger flow is provided, a kind of plunger pump is disclosed among the CN100467863C, comprise two piston casings that are interconnected, the axis of two piston casings is in a certain angle, also namely V-shaped, although the V-type plunger pump can symmetrically increase plunger quantity with augmented flow and rated lift, but two minute casing still keep certain angle with vertical direction, take 60 ° of angles wherein as example, plunger in the plunger pump so, guide rod, spool, valve seat can bear 30% heel and toe wear in to-and-fro motion, this one-sided wearing and tearing can aggravate the wear rate of these reciprocating members greatly, reduce its working life, cause comparatively frequently shutdown maintenance to the user, produce extra expense.In addition, the material of the reciprocating member of plunger pump in the past is commonly alloyed steel, modified, nitrogenize, use after the polishing, plunger is to be issued to into water at reciprocating, the purpose of draining, for the slime water that contains solid particle, under long duration of action, solid particle is to the guide piston bar, spool, the surface of valve seat is easy to cause scratch, collision, make their surface irregularity, these surfaces will reduce greatly to the effect of O type circle sealing so, because plunger pump water inlet process is a kind of vacuum dehydration process, sealability is very important, and long term wear can cause plunger pump ventilative, permeable, advance, drainage procedure just can't normally carry out.
The model utility content
The technical problem that the utility model solves provides the plunger pump that a kind of wearing and tearing are less, the life-span is longer.
The technical solution adopted in the utility model is, plunger pump, comprise the piston casing and in the piston casing reciprocating rod-plunger assembly, the center line of described piston casing is vertical direction, the rod-plunger assembly is done the to-and-fro motion of vertical direction in the piston casing.
Described rod-plunger assembly comprises guide piston bar, water filling plunger, the guiding gland that is connected from bottom to top, and the spool, the spring that periodically are subjected to the piston rod pushing tow.
Piston casing below is provided with crankcase body, and the bent axle in the crankcase body is provided with at least two crank throws, and crank throw is connected with the guide piston bar by connecting rod.
The Rockwell hardness of the face that is slidingly matched of rod-plunger assembly and piston casing is greater than 70, and surface roughness is at least the minute surface rank.
The beneficial effects of the utility model are that plunger and bent axle form 90 ° vertical motion, have eliminated the deviator resistance that plunger is received, have reduced simultaneously the heel and toe wear of plunger pump reciprocating member, have improved working life, have dwindled the floor space of plunger pump.
Description of drawings
Fig. 1 is the utility model structural perspective.
Fig. 2 is the plan view of the utility model plunger pump.
Fig. 3 is along the sectional view of A-A direction among Fig. 2.
Be labeled as among the figure: 1-bent axle, 2-crankcase body, 3-suction chamber housing, 4-pump cover housing, 5-guide piston bar, 6-water filling plunger, 7-spool, 8-valve seat, 9-connecting rod.
Embodiment
As shown in Figure 1, plunger pump of the present utility model lower end is crankcase body 2 and is installed on bent axle 1 in the crankcase body 2, and crankcase body 2 is fastened by two-part up and down, and lower part is bolted on the base plate of level.Bent axle 1 is provided with at least 2 crank throws, preferred 3-8, crank throw drives guide piston bar 5 by connecting rod 9 and pumps, termination, guide piston bar 5 bottom is positioned at crankcase body 2, crankcase body 2 is provided with piston cavity, and piston cavity is provided with guide sleeve, and the outer surface of its internal surface and guide piston bar 5 is slidingly matched, the piston cavity top of crankcase body 2 is provided with black box, keeps the good tightness of guide piston bar 5 and piston cavity.Suction chamber housing 3 is passed at the middle part of guide piston bar 5, and top drives water filling plunger 6 and moves upward, and the top of guide piston bar 5 is along with moving up and down the spool 7 in the periodic pushing tow outlet component.Outlet component is positioned at the pump cover housing 4 on top, comprises the parts such as spool 7, valve seat 8, limited post and spring.
Piston casing of the present utility model refers to have with plunger pump in the move up and down housing of the inner chamber that is slidingly matched of reciprocating member, comprise the piston cavity of crankcase body 2, wherein guide sleeve; Suction chamber housing 3 inner chambers; And pump cover housing 4, valve seat 8 wherein, the center line of these parts, the direction that also is axis is vertical direction, the axial direction of bent axle is substantially horizontal, and the motion of the reciprocating members such as guide piston bar 5, water filling plunger 6, spool 7, valve seat 8 is fully vertical with substantially horizontal so, and they are not radially stressing, and deviator friction radially is zero, can not cause the life-span of part too short because of the serious wear of part.
In order to reduce to greatest extent the wearing and tearing of reciprocating member, the surface hardness of all reciprocating members will arrive HRC70 simultaneously, and surface roughness reaches the minute surface rank, and material is selected upper preferred nickel-base alloy powder, and to parent hot spraying, grinding.When containing solid particle in the liquid, because the surface hardness of these reciprocating members is high, the destructiveness of particle aligned surfaces is just minimum, and good surface can make plunger pump keep good sealability within a very long time, therefore, can deal with the insurmountable slime water that contains particle of other pump.
