Analysis And Research On Generalized Heart Track Radial Plunger Pump With Rolling Slipper Boots

As the heart of hydraulic system,hydraulic pump on the displacement,noise,pressure,flow and other technical indicators and accuracy of the requirements are increasingly high.The advantage of cylindric rotary internal curve plunger pump is that the plunger can make use of the inertia force and centrifugal force of rotor rotation,among which the selection and optimization of stator guide curve is very important.Combined with plunger and sliding shoe structure,the performance of radial plunger pump can be further improved.Based on the introduction of the main advantages of hydraulic technology and the present academic and applied research status,this paper briefly introduces the structural differences and working principles of conventional radial plunger pump,explains the advantages and disadvantages of relevant plunger pump,and points out one of the important factors affecting the performance of the plunger pump,the stator curve.According to the knowledge of analytic geometry,by changing the amplitude and fluctuation of the heart-shaped line according to certain rules,a series of new guideway curves of radial plunger pump can be obtained,namely,generalized heart-shaped line.The curve is easy to draw and can solve the problem of reducing flow pulsation and internal contact stress of the plunger pump.It is applied to the radial plunger pump of rolling slipper as the central motion track of double ball head,and a series of motion guide curve obtained has excellent expansibility.Using the directional quantitative research methods,reduce the influence of uncertain variables,and analysis to explore the number of different roles,different number of the plunger,axle ratio coefficient of rolling sliding boots is the influence of radial piston pump flow pulsation,and its flow pulsation is using the MATLAB software simulation,studied the rolling sliding boots radial piston pump plunger parts of inhalation of transmission medium and the pressure transmission medium in the process of mechanical analysis,establish the related theory of data model,help to analysis the rolling performance of sliding boots radial piston pump,the results obtained for the rolling radial piston pump structure design of sliding boots provide certain theoretical reference.The simulation and modeling results show that the double-acting hydraulic pump has certain advantages in the current research.When the number of plungers is odd,the pulsation of the radial hydraulic pump with generalized heart orbit of sliding boots gradually decreases with the increase of the number of plungers,and when the number is even,the pulsation is obviously greater than that with odd number.The radial hydraulic pump axial ratio coefficient has little influence on the flow fluctuation.The force N in the center of the connecting rod increases with the increase in,and shows a quadratic square relationship,with the increase in,the force N also increases faster and faster.The radial hydraulic pump with generalized heart-shaped track is superior to the ordinary internal curve plunger pump in terms of flow fluctuation and internal contact stress.According to the generalized heart-shaped lines is practical,reference on the market,and in theory research of plunger pump structure and study in laboratory design complete hydraulic ball pump,on the basis of rolling sliding boots to complete the preliminary structure design of radial piston pump,and modeling analysis,design the application of the initial structure of the stator curve of the piston pump.Then the hydraulic test system is designed according to the characteristics of the hydraulic pump,which can be verified in the subsequent verification test.
