Embodiment
Fully to explain the technical solution of the utility model, illustrated below in conjunction with accompanying drawing.
Illustrate：The direction of arrow shown in Fig. 1 circulates direction for hydraulic oil.
As shown in figure 1, embodiment of the present utility model provides a kind of hydraulic thrust device.The device includes being interconnected
Send oily portion 1 and work department 2, work department 2 includes oil cylinder body 26, pressure watt 22 and thrust piston 24, in oil cylinder body 26
Pressure oil cavity 21, driving oil pocket 23 and oil back chamber 27 are offered, pressure oil cavity 21 is respectively with sending oily portion 1 and oil back chamber 27 to be connected
Logical, with sending oily portion 1 to be connected, pressure watt 22 is movably disposed in pressure oil cavity 21 oil back chamber 27, and oil cylinder body 26 is also opened
Provided with thrust through hole 25, thrust through hole 25 is connected with driving oil pocket 23, and thrust piston 24 is arranged in thrust through hole 25, pressure
Hydraulic oil in watts 22 extruding driving oil pockets 23 is to extrude the movement of thrust piston 24 to export power.
The simple Tilting Pad bearing loading device pressurizeed by unidirectional quantitative hydraulic valve and convey in fuel tank oil from
And the movement of bidirection press watt 22 is extruded, then the hydraulic oil in the extruding driving oil pocket 23 of pressure watt 22 promotes thrust piston 24 to move
Move to export power, so as to be loaded to the tile fragment of radial direction tilting-pad bearing, that is, realize to the bearing by the fast of loading capability
Speed detection, reduces the workload of existing Tilting Pad bearing test-bed, improves operating efficiency.
During power is exported, hydraulic oil of the pressure watt 22 in extruding driving oil pocket 23 extrudes oil back chamber 27 simultaneously
In hydraulic oil so that the hydraulic oil in oil back chamber 27, which is back to, to be sent in oily portion 1.After power output is done work, pressure oil
Connecting valve between chamber 21 and oil back chamber 27 is opened, and oil back chamber 27 and sending is controlled on connecting line between oily portion 1
Valve is closed, and now persistently send oil, and the hydraulic oil squeeze pressure watt 22 in oil back chamber 27 is displaced outwardly, and is at this moment driven in oil pocket 23
Form negative pressure and form pressure difference with atmospheric pressure, thrust piston 24 is returned to original position in the presence of the pressure difference.
