Description

A kind of high speed axial variable displacement plunger pump
Technical field
This utility model relates to a kind of plunger displacement pump, particularly relates to a kind of high speed axial variable displacement plunger pump.
Background technology
Axial plunger pump is the dynamical element of hydraulic system, by changes mechanical energy is become hydraulic energy, and certain pressure required when hydraulic system offer work and the hydraulic fluid of flow, make each execution unit of hydraulic pressure complete the action of various regulation.Due to axial plunger pump compact conformation, realizing variable and be easier to, have the biggest benefit to energy-conservation, electromechanical integration, therefore, axial plunger pump prosperity so far does not wanes, and has broad based growth prospect.In some field, common axial plunger pump usually can not meet special technology requirement, needs to carry out special exploitation and research.
Summary of the invention
The purpose of this utility model is to provide a kind of high speed axial variable displacement plunger pump, this utility model high speed axial variable displacement plunger pump uses swash plate rotary diacytic type axial plunger pump, and on the basis of dosing pump under addition of variable mechanism, and the environment of variable higher for maximum speed.
The purpose of this utility model is achieved through the following technical solutions:
A kind of high speed axial variable displacement plunger pump, described plunger displacement pump includes main shaft, housing, valve plate, cylinder body, plunger, swash plate, variable bar;Electromotor connects main shaft by gear, main shaft connects valve plate and swash plate, it is evenly distributed on cylinder body and has plunger, variable actuating unit is provided with variable bar, variable bar connects with swash plate, and plunger is located in cylinder holes, and cylinder body is fixing shape, swash plate installs axial thrust rolling bearing additional, uses point cantact between swash plate and plunger;The velocity-measuring system of engine fuel control system is connected with electromotor, and be connected with speed setting controller, error signal is connected with Variable plunger pump electric control system after amplifying in the form of a voltage, and constituting the closed loop with engine speed as manipulated signal can be for regulation system.
Described a kind of high speed axial variable displacement plunger pump, described valve plate is provided with eccentric swing and leads to hydraulic fluid port.
Advantage of the present utility model with effect is:
This utility model uses swash plate and rotates, and cylinder body is fixed, and reduces the rotary inertia of pump, thus improves the rotating speed of pump.In terms of stroking mechanism, swash plate both rotated, and swung again, thus realized variable.This utility model volume is little, lightweight.This utility model reduces manufacture requirements and cost.
Accompanying drawing explanation
Fig. 1 is this utility model engine fuel control system schematic diagram;
Fig. 2 is this utility model structural representation.
Detailed description of the invention
This utility model is described in detail by illustrated embodiment below in conjunction with the accompanying drawings.
A kind of high speed axial variable displacement plunger pump, including main shaft 1, housing 2, valve plate 3, cylinder body 4, plunger 5, swash plate 6, variable bar 7.
Stroking mechanism principle of the present utility model is to change swashplate angle to realize variable, and swash plate both rotated, and swung again.Actuating motor promotes swash plate to change angle of inclination by drive mechanism, thus changes pump delivery, changes the flow of fluid in pump, it is achieved variable.High speed axial variable displacement plunger pump is installed in certain engine fuel control system, fuel supercharging is delivered to fuel chambers, thus promotes electromotor to work.
As it is shown in figure 1, this utility model is according to the needs of engine fuel control system, fuel supercharging is delivered in combustor, and then promote electromotor work.Velocity-measuring system sends the engine speed of mensuration to speed setting controller, compare with instruction rotating speed, error signal sends Variable plunger pump electric control system after amplifying in the form of a voltage to, thus constitutes the closed loop with engine speed as manipulated signal and can supply regulation system.
As in figure 2 it is shown, this utility model hydraulic principle and work process are as follows: this utility model structurally uses cylinder body 4 to fix, and swash plate 6 rotates.Swash plate 6 inclination angle to be changed realizes variable it is necessary to swash plate 6 both rotated, and swings again.By electromotor by gear drive shaft 1, thus driving valve plate 3 and swash plate 6 to rotate, cylinder body 4 then remains stationary as.The rotation of swash plate 6 promotes the plunger 5 being evenly distributed on cylinder body 4 to move reciprocatingly in cylinder holes, and the valve plate 3 leading to hydraulic fluid port by having eccentric swing completes oil suction and force feed.When needs variable, variable actuating unit drives variable bar 7, if variable bar 7 moves right, makes swash plate 6 inclination angle strengthen, thus the stroke that plunger 5 is in cylinder holes lengthens, and pump delivery strengthens.Otherwise, variable bar 7 to left movement time, pump delivery reduce.This utility model uses swash plate 6 and rotates, cylinder body 4 is fixed, reduce the rotary inertia of pump, and install axial thrust rolling bearing at swash plate 6 position additional, increase the rigidity of swash plate 6, reduce the mechanical loss of pump, point cantact is used between swash plate 6 and plunger 5, reduce leakage link, reduce manufacture requirements and cost, thus improve the rotating speed of pump.
