Abstract
The utility model discloses an energy-saving hydraulic-control variable axial plunger pump which comprises an electromagnetic directional valve, a hydraulic-control variable device, and a maximal discharge capacity manual regulation device. The utility model has the advantages of reasonable structure, easiness in installation, low no-load power loss, and less system heating phenomenon.
Description
Technical field:
The utility model relates to a kind of axial piston pump.
Background technique:
Existing hydraulic control axial variable displacement plunger pump, with the full flow running, power loss is big when causing zero load always in system, and system generates heat easily.
Summary of the invention:
The purpose of this utility model is to provide a kind of charged magnetic selector valve, and is simple in structure, saves no-load power consumption, and maximum pump discharge is adjustable hydraulic control axial variable displacement plunger pump manually.
Technical solution of the present utility model is: a kind of energy-saving hydraulic control axial variable displacement plunger pump, comprised solenoid directional control valve, the hydraulic control variable device, the maximum pump discharge manual regulating device, it is characterized in that: solenoid directional control valve is housed in hydraulic control variable device upper end, the maximum pump discharge manual regulating device is equipped with in the lower end, the epicoele of solenoid directional control valve A mouth and variable shell is connected, solenoid directional control valve B mouth connects by the oil pipe between the last lower flange of variable part, connect with the cavity of resorption of variable shell, during the electromagnet no electric circuit, solenoid directional control valve P mouth is connected with the B mouth, and the A mouth is connected with the T mouth, during the electromagnet energising, solenoid directional control valve P mouth is connected with the A mouth, and the B mouth is connected with the T mouth.
The utility model is rational in infrastructure, on existing hydraulic control variable basis, has increased solenoid directional control valve, be near zero displacement position when unloaded, power loss is little, has reduced system's heating, increased the maximum pump discharge manual regulating device in addition, can obtain different peak rate of flow according to different needs.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a structural representation; Fig. 2 is the structural representation of Figure 1A-A section.
Embodiment:
When driving the electric motor starting of hydraulic control axial variable displacement plunger pump, the electromagnet no electric circuit, system does not work, and external control oil enters from the P mouth of upper flange 2, and the P mouth by solenoid directional control valve 1 is connected with the B mouth, the A mouth is connected with the T mouth, B mouth between upper flange 2, the lower flange 5 externally connects by oil pipe, and just external control oil is by B mouth entering variable housing 3 cavity of resorptions, and variable shell 3 epicoeles and solenoid directional control valve 1 drain tap are connected (fluid oil sump tank), promote to move on the variable piston 4, arrive near the position of zero delivery.The electromagnet energising, system starts working, external control oil enters from the P mouth of upper flange 2, P mouth by solenoid directional control valve 1 is connected with the A mouth, the B mouth is connected with the T mouth, and just external control oil is by A mouth entering variable housing 3 epicoeles, and variable shell 3 cavity of resorptions and solenoid directional control valve 1 drain tap are connected (fluid oil sump tank), promote variable piston 4 and move down, arrive displacement.The maximum pump discharge manual regulating device is adorned an adjusting screw rod 6 in variable piston 4 lower ends exactly, and the range of dominated variable piston can obtain different peak rate of flow.
