Description
Technical field
The present invention relates to a kind of plunger displacement pump, particularly relate to a kind of high speed axial variable displacement plunger pump.
Background technology
Axial plunger pump is the dynamical element of hydraulic system, and by mechanical energy is changed into hydraulic energy, while providing work to hydraulic system, required certain pressure and the hydraulic fluid of flow, make the each execution unit of hydraulic pressure complete the action of various regulations. Due to axial plunger pump compact conformation, to realize variable easier, and energy-conservation, electromechanical integration are had to very large benefit, therefore, axial plunger pump so far prosperity does not wane, and has wide development prospect. In some field, common axial plunger pump usually can not meet special technical requirement, need to carry out special exploitation and research.
Summary of the invention
The object of the present invention is to provide a kind of high speed axial variable displacement plunger pump, high speed axial variable displacement plunger pump of the present invention adopts the rotary diacytic type axial plunger pump of swash plate, and on the basis of constant displacement pump addition of variable mechanism, under the environment of and variable higher for maximum speed.
The object of the invention is to be achieved through the following technical solutions:
A kind of high speed axial variable displacement plunger pump, described plunger displacement pump comprises main shaft, housing, valve plate, cylinder body, plunger, swash plate, variable bar; Engine connects main shaft by gear, main shaft connects valve plate and swash plate, be evenly distributed on and on cylinder body, have plunger, variable actuating unit is provided with variable bar, variable bar and swash plate join, and plunger is located in cylinder hole, and cylinder body is fixing shape, swash plate installs axial thrust rolling bearing additional, adopts point to contact between swash plate and plunger; The velocity-measuring system of engine fuel control system is connected with engine, and be connected with speed setting controller, error signal is connected with Variable plunger pump electric control system with the form of voltage after amplifying, and the closed loop forming taking engine speed as manipulated signal can be for regulating system.

Advantage of the present invention and effect are:
What the present invention adopted is swash plate rotation, and cylinder body is fixed, and has reduced the rotary inertia of pump, thereby improves the rotating speed of pump. Aspect stroking mechanism, swash plate both rotated, and swung again, thereby realized variable. Volume of the present invention is little, lightweight. The present invention has reduced manufacture and has required and cost.
Brief description of the drawings
Fig. 1 is engine fuel control system schematic diagram of the present invention;
Fig. 2 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is described in detail.
A kind of high speed axial variable displacement plunger pump, comprises 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 invention is to change swashplate angle to realize variable, and swash plate both rotated, and swung again. Actuating motor promotes swash plate by transmission mechanism and changes angle of inclination, thereby changes pump delivery, changes the flow of fluid in pump, realizes variable. High speed axial variable displacement plunger pump is installed in certain engine fuel control system, and fuel pressure boost is delivered to fuel chambers, thereby promotes engine operation.
As shown in Figure 1, the present invention, according to the needs of engine fuel control system, delivers to fuel pressure boost in combustion chamber, and then promotes engine operation. Velocity-measuring system sends the engine speed of mensuration to speed setting controller, and instruction rotating speed compares, error signal sends Variable plunger pump electric control system to the form of voltage after amplifying, thereby the closed loop forming taking engine speed as manipulated signal can be for regulating system.
As shown in Figure 2, hydraulic principle of the present invention and the course of work are as follows: the present invention structurally adopts cylinder body 4 fixing, and swash plate 6 rotates. Change swash plate 6 inclination angles and realize variable, will both rotate by swash plate 6, swing again. Pass through gear drive shaft 1 by engine, thereby drive valve plate 3 and swash plate 6 to rotate, 4 maintenances of cylinder body are motionless. The rotation of swash plate 6 impels the plunger 5 being evenly distributed on cylinder body 4 to move reciprocatingly in cylinder hole, completes oil suction and force feed by the rotary valve plate 3 with the logical hydraulic fluid port of eccentric swing. In the time of needs variable, variable actuating unit drives variable bar 7, if variable bar 7 moves right, swash plate 6 inclination angles are strengthened, thereby the stroke of plunger 5 in cylinder hole lengthens, and pump delivery strengthens. Otherwise during to left movement, pump delivery reduces at variable bar 7. What the present invention adopted is that swash plate 6 rotates, cylinder body 4 is fixing, reduce the rotary inertia of pump, and install axial thrust rolling bearing additional at swash plate 6 positions, increase the rigidity of swash plate 6, reduce the mechanical loss of pump, between swash plate 6 and plunger 5, adopt point to contact, reduce and leak link, reduce to manufacture requiring and cost, thereby improve the rotating speed of pump.
