Description
The present invention relates to a kind of reciprocating pump that radially distributes, especially for the reciprocating pump of carrying the liquid system working liquid body, radially cylinder is arranged in its structure, the radial piston that has piston head, piston actuated is held piece, an eccentric driving part and radial piston and piston actuated held the device that piece couples together.The supporting surface of piston head and match with supporting surface that the piston actuated of its termination is held piece, but be not rigidly connected.The other end that piston actuated is held piece presses closer on eccentric driving part.Each piston head all has an outward flange, and end face clamps by radial piston and piston actuated being held the device that piece couples together thereafter, and eccentric driving part can be an eccentric hoop or an eccentric shaft.According to both of these case, radial piston can be driven by the eccentric position of eccentric hoop or the eccentric position of eccentric shaft, and radially cylinder is to arrange like this, for example, can hold the outside or the inboard of piece in piston actuated.Pump case needs to have different structures according to different situations.Clearly, this class radial piston pump can with common device adapted carrying and the regulator solution body medium, but this does not belong to scope of the present invention, so superfluous words no longer.The device that this pump also can be used for bearing to be adopted.For example, to hydrodynamic journal liquid polymers transportation work liquid.Reciprocating pump can drive by eccentric part or by housing, also might be with these two kinds of assemblies of different speed driving (see D.B.P. 1155336, the 4 hurdles, 31-51 is capable).
In this known plain edition radial piston pump (D.B.P. 2915239), it is a connecting ring that radial piston and piston actuated are held the device that piece couples together, it is around the whole periphery of radial piston pump, it is coupling together radial piston and eccentric driving part in the radial direction, piston actuated is held piece and is placed in the middle of them, and connecting ring is installed with the eccentric part of actuator is concentric.And this is only in sizable space and need considerable mounting cost just can accomplish, refers to eccentric driving part here and is one and have the situation of the eccentric hoop of known structure form.In this case, in fact also be so really, to be connecting ring in piston head and piston actuated hold needs not be a kind of being rigidly connected between the piece, yet, concerning the radial piston pump of fast turn-around, above-mentioned part will produce very big wearing and tearing owing to the violent to-and-fro motion of eccentric hoop, and simultaneously, connecting ring also will produce distortion and fatigue crack.In this respect, the situation with another kind of radial piston pump (D.B.P. 1403748) generation is similar.In a kind of radial piston pump in back a kind of so-called piston pressure ring is installed, they are installed on the both sides of radial piston and clamp in the both sides of piston head outward flange back.This just need hold a kind of being rigidly connected of formation between the piece at piston head and piston actuated.And can make wearing and tearing quicken also often to occur fatigue crack.
The objective of the invention is to propose a kind of radial piston pump illustrated when beginning.Hold in the piston head of this pump and piston actuated and need not between the piece to be rigidly connected, also no longer needed by the connecting ring of aforementioned manner setting, and concerning eccentric driving part, can be according to people's wish, it is not difficult to make eccentric hoop or eccentric shaft.
According to the present invention, radial piston and piston actuated are held the device that piece couples together form by being connected lining.This device is had by each radial piston.Each device all has an inward flange, and it will clamp piston head from the back of the outward flange of piston head.It holds piece one side in piston actuated and also has a sealing ring, and this collar will hold piece from the position, outer surface back that the piston actuated of correspondence is held piece and clamp.One ring-spring bearing is arranged on the lining of radial piston one side, and corresponding is also has a spring support in the periphery of cylinder radially, between the bearing of lining bearing and cylinder periphery a stage clip is installed.According to optimum structure form of the present invention, each connects lining and all is made up of two ring parts, and one of them is a sealing ring.With screw itself and another ring part is coupled together, these screws are positioned at and connect lining in the radial direction.
The radial piston pump that proposes according to the present invention, eccentric driving part can be an eccentric hoop or an eccentric shaft.Each part utmost point is not easy to wear and the life-span is long, and the eccentric driving part that it is characterized in that reciprocating pump optimum structure form is an eccentric shaft.It is proper that cylinder radially is embedded in each cylinder shell by the cylinder liner mode.These cylinders are distributed in the periphery of radial piston pump by star.Usually the stage clip that adopts is a helical spring, but also can adopt cup spring.
The radial piston pump that proposes according to the present invention has such advantage, promptly no longer needs to adopt a kind of connecting ring of addressing previously with peripheral profile.Can adopt to connect the connecting ring that the lining replacement is easy to damage, the precision processing that the former can be very high is not even if after long-term the use, the precision of radial piston pump can reduce yet and cause breaking down.Therefore, the radial piston pump that proposes according to the present invention had both just driven with very high rotating speed and had also had the extremely long life-span.
By way of example one embodiment of the invention is illustrated referring now to accompanying drawing:
Figure 1 shows that the part of the radial piston pump transverse section that proposes according to the present invention.Figure 2 shows that along the partial view of direction shown in Fig. 1 bottom arrow.
Figure 1 shows that the transverse section of the part radial piston pump that proposes according to the present invention.Axis and the radially axis of cylinder 2 of this transverse section by eccentric drive shaft 1.Because along a plurality of radially cylinders 2 of circumferential distribution, therefore content described below all refers to a plurality of cylinders.The radial piston pump that is proposed is used for the working fluid of delivery hydraulic pressure system, particularly water.Except that cylinder 2 radially, have the radial piston 3 of piston head 4 in the main member of pump in addition, piston actuated is held piece 5.One eccentric driving part (in the present embodiment for eccentric shaft 1) and be connected radial piston 3 and piston actuated is held the device of piece 5.
The supporting surface 7 that the supporting surface 6 of piston head 4 and the piston actuated that is in contact with it are held piece 5 matches, and the two is not rigidly connected.The other end of piston actuated anchor plate 5 presses closer on eccentric driving part 1.Each piston head 4 all has an outward flange 8, and end face clamps by radial piston 3 and piston actuated being held the device that piece 5 couples together thereafter.This connection set includes and connects lining 9.This lining is had by each radial piston 3.Its inward flange 10 contacts with the position, back of the outward flange 8 of piston head 4.There is a sealing ring 11 in the outside of holding piece in piston actuated, and the aft section that it holds piece 5 outer surfaces in piston actuated will be held piece and be clamped.Connect lining 9 and one annular spring bearing 12 is arranged in radial piston one side.Corresponding, radially around the cylinder 2 spring support 13 is being arranged.Between annular ledge 12 and the bearing 13 installed around the cylinder, around radially cylinder 2(and radial piston 3) the outside one helical compression spring is housed.
Can see that each connects lining 9 all two ring part 9a and 9b, 9a has wherein constituted sealing ring 11, and borrows screw 15 to be connected with another ring part 9b.Screw 15 is connecting lining 9 in the radial direction.
Radially cylinder 2 embeds in the cylinder shell 16 in the lining mode.They radially the reciprocating pump periphery be star and distribute.
