Description
Technical field
The utility model relates to a kind of transmission device of hydraulic system, and especially a kind of plunger pump, belongs to mechanical equipment technical field.
Background technique
Plunger pump is an important device in hydraulic system, it is a kind of typical positive displacement hydraulic machinery, by motoring during its work, and rely on the to-and-fro motion of plunger in cylinder body, the volume of seal operation cavity volume is made to change to realize oil suction, force feed, so achieve the pressure energy mechanical energy of input being converted into liquid, then be input in system with the form of pressure, flow and go, therefore it is the power source of hydraulic system.The plunger pump advantages such as rated pressure is high owing to having, compact structure, efficiency are high and Flow-rate adjustment is convenient, therefore the occasion that high pressure, large discharge and flow need to regulate is widely used in, in such as hydraulic press, engineering machinery and boats and ships, and because it under high pressure can carry liquid, the industry-by-industry therefore in industrial production and daily life is all widely used.The plunger pump now used at present is mainly divided into axial piston pump and radial plunger pump two kinds of structural types, wherein, radial plunger pump is due to higher to the required precision of equipment unit, and overall structure is comparatively complicated, technical requirements is higher, therefore domestic making is used less at present, and people use axial piston pump.But, now current axial piston pump in use, usually there will be and rock violent situation, find it is due to the too rigidity of the connection between motor and the pump housing on inspection, cause once occur being provided with deviation, the pump housing will operationally produce strong rocking, and this has a great impact the stability of whole system work; Moreover, also there is the too complicated problem of installation in existing plunger pump, in order to make connecting of the pump housing and motor, usually needing a lot of bolts etc. to fix from multiple directions, being so both not easy to installation, being also not easy to maintenance overhaul.
Model utility content
For above-mentioned deficiency of the prior art, main purpose of the present utility model is to solve existing current plunger pump structure less stable, easily produces the problem of rocking, and provides a kind of good operating stability, plunger pump easy for installation.
The technical solution of the utility model: a kind of plunger pump, it is characterized in that, comprise the pump housing of motor and plunger pump, described motor is arranged on underframe, the output shaft of motor is connected with the first coupling, and one end of described first coupling and force-transmitting block is connected and fixed, and the other end and second coupling of described force-transmitting block are connected and fixed, described second coupling is arranged on the input shaft of the pump housing, and the central shaft of the described pump housing is overlapping with the central shaft of motor.
Optimally, the shell of described motor is also provided with flange cylinder, and described flange cylinder is cone structure, and one end of flange cylinder is fixed on motor, the other end of flange cylinder is fixed on the shell of the pump housing, and described flange cylinder and motor and the pump housing are bolt and are connected and fixed.Can increase join strength between motor and the pump housing by described flange cylinder, rocking when being simultaneously also conducive to reduction work, has ensured the stability of equipment work.
Optimally, described motor is bolted on underframe, between described motor and underframe, be also provided with shock absorption strip.Here self vibration time by arranging shock absorption strip and can reducing motor work, also helps reduction noise.
Optimally, the first described coupling and the second coupling are elastic coupling flexible coupling.Inharmonious between motor output shaft and pump housing input shaft can be reduced by elastic coupling flexible coupling and rock, being conducive to the smooth working of maintenance equipment.
Optimally, an annular vent hole is also provided with at the middle part of described flange cylinder.Here the effect arranging vent hole is convenient heat radiation, whether normally conveniently can also observe inner parts etc. simultaneously.
Relative to prior art, the utility model has following beneficial effect:
1, good operating stability: plunger pump of the present utility model have employed two elastic coupling flexible couplings to connect motor and the pump housing, can either ensure that connection is fastening, the impact of motor vibrations on pump housing work can be slowed down again, ensure stability during pump housing work therefore, it is possible to effective.
2, fitting operation is convenient: plunger pump of the present utility model adopts the shell of flange cylinder to electric machine casing and the pump housing of taper to be fixed, further strengthen stability therebetween, workman is also convenient when mounted simultaneously, only bolt corresponding on flange cylinder need be installed, also very easy when needs maintenance and inspection.
3, good damping result, noise is also less, has larger Applicable scope.
