Abstract
The invention discloses an inclined shaft type plunger pump device. The inclined shaft type plunger pump device comprises a main shaft, a bearing, a connecting rod plunger pair, a cylinder, a shell, a valve plate and a back cover, wherein one end of a rotating shaft is connected with the inner wall of one end of the shell through the bearing; the shell is bent; one end of the rotating shaft in the shell is connected with the connecting rod plunger pair; the connecting rod plunger pair is connected with the cylinder; the cylinder is connected with the valve plate; the back cover is arranged at the other end of the shell; and the connecting rod plunger pair, the cylinder and the valve plate are sealed in the shell through the back cover. In the inclined shaft type plunger pump device, the lateral force of the plunger is smaller than the lateral force of the plunger of a straight shaft type pump, so that the frictional loss caused by the lateral force is low; and the connection between a connecting rod bulb and the main shaft is firm, so that the self-priming capacity is stronger.
Description
Technical field

Background technique
China produces inclined plunger pump-unit and starts from nineteen sixty, but kind and quantity are all fewer, 1978, oil hydraulic pump factory of one, Pekinese introduced more than 500 serial specification kind of A2F metering pump, A6V variable displacement motor, A7V variable displacement pump and A8V variable dual-pump four from extra large Drolma Di Ke company of Germany.Subsequently, Shanghai Hydraulic Pump Factory has introduced again the metering pump of A2F6.1 structure.At present, China can production discharge capacity from 10ml/r to 500ml/r, rated pressure is 35MPa, maximum pressure reaches the plurality of specifications of 45MPa, the inclined shaft pump of multiple variable pattern.But existing pump performance still can not meet and develops to obtain needs.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, the inclined plunger pump-unit of better performances is provided.
Consider the problems referred to above of prior art, according to an aspect of the present invention, for solving above-mentioned technical problem, the present invention by the following technical solutions:
A kind of inclined plunger pump-unit, comprise main shaft, bearing, rod-plunger pair, cylinder body, housing, thrust plate and bonnet, described rotating shaft one end is connected with the inwall of shell one end by bearing, described housing is curved shape, the rotating shaft one end being positioned at housing is connected with rod-plunger pair, and described rod-plunger pair is connected with cylinder body, and described cylinder body is connected with described thrust plate, the described housing the other end is provided with bonnet, rod-plunger pair, cylinder body and thrust plate is enclosed in described housing by described bonnet.
In order to realize the present invention better, further technological scheme is:
According to one embodiment of present invention, described bonnet is connected with the end face of housing by bolt.
According to one embodiment of present invention, the bend angle of described housing is 110 degree to 120 degree.
According to one embodiment of present invention, described bearing is 3.
According to one embodiment of present invention, described bearing is selfaligning ball bearing.
According to one embodiment of present invention, described rod-plunger pair comprises 3 connecting rods.
According to one embodiment of present invention, described rod-plunger is secondary is spherical with the connecting end of main shaft.
The present invention can also be:
According to one embodiment of present invention, described rod-plunger pair is connected with main axis.
Compared with prior art, one of beneficial effect of the present invention is:
Inclined plunger pump-unit of the present invention, the lateral force of plunger is less than the plunger lateral force of direct shaft type pump, and therefore, the frictional loss caused by lateral force is little; Connection rod sphere and main shaft are connected firmly, and have stronger suction capacity.
Accompanying drawing explanation
In order to clearer explanation present specification embodiment or technological scheme of the prior art, below the accompanying drawing used required in the description to embodiment or prior art is briefly described, apparently, the accompanying drawing that the following describes is only the reference to some embodiments in present specification, for those skilled in the art, when not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 shows the structural representation of inclined plunger pump-unit according to an embodiment of the invention.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment 1
Fig. 1 shows the structural representation of inclined plunger pump-unit according to an embodiment of the invention.A kind of inclined plunger pump-unit as shown in Figure 1, comprise main shaft 101, bearing 102, rod-plunger pair 103, cylinder body 104, housing 105, thrust plate 106 and bonnet 107, described rotating shaft 101 one end is connected with the inwall of housing 105 one end by bearing 102, described housing 105 is curved shape, rotating shaft 101 one end being positioned at housing 105 is connected with rod-plunger pair 103, described rod-plunger secondary 103 is connected with cylinder body 104, described cylinder body 104 is connected with described thrust plate 106, described housing 105 the other end is provided with bonnet 107, by described bonnet 107 by rod-plunger pair 103, cylinder body 104 and thrust plate 106 are enclosed in described housing 105.
Described bonnet 107 is connected with the end face of housing 105 by bolt 108.
The bend angle 109(of described housing 105 as shown in fig. 1 outer wall at the angle of crooked position) be 110 degree to 120 degree.
Described bearing 102 can be 3.
Described bearing 102 can be selfaligning ball bearing.
Described rod-plunger pair 103 can comprise 3 connecting rods.Described rod-plunger secondary 103 is spherical with the connecting end of main shaft 101.
Described rod-plunger secondary 103 is rotationally connected with main shaft 101.
Embodiment 2
Main shaft support is on 3 bearings, and one of them bearing can also be duplex angular contact ball bearing, and it can bear larger axial force, also can bear certain radial force.Another bearing is wherein deep groove ball bearing, mainly bears radial force.Bearing pack can ensure main shaft stably High Rotation Speed have longer working life.
Bearing place can arrange belleville spring (can abut against the left side bearing shown in Fig. 1), is used for ensureing the pretightening force of paired duplex angular contact ball bearing, also can make that bearing works well when High Rotation Speed and noise is less simultaneously.
End cap, by the gap between O type circle end cover and housing, prevents from revealing.Rod-plunger pair can be linked together by connecting rod and plunger two part footpath roll extrusion.The large bulb of connecting rod is pressed in the ball-and-socket of main shaft by backhaul plate, and the little bulb of connecting rod matches with the ball-and-socket in plunger, and plunger does straight reciprocating motion in cylinder body.Can adopt sphere flow between cylinder body and thrust plate, and be pressed on thrust plate by the belleville spring overlapped on center shaft by cylinder body, thus cylinder body has good self-alignment when rotated, and has higher volumetric efficiency.Central shaft is bearing between alignment of shafts ball-and-socket and the center hole of thrust plate, and it can ensure that cylinder body turns round around central shaft well.
