Movable plate 4, spring 5 and measurement part；Column 2 is arranged vertically on pedestal 1, that is to say, that when pedestal 1 is horizontal positioned
When, column 2 should be placed vertically；Top plate 3 is fixed on column 2 transverse to column 2, is provided with aperture on top plate 3；
Movable plate 4 is arranged between pedestal 1 and top plate 3 and can move along the length direction of column 2, i.e., as illustrated in fig. 1 and 2, activity
Plate 4 can move up and down；One end of spring 5 connects top plate 3, and the other end connects movable plate 4, spring 5 have original state and
Compressive state, it should be appreciated that spring 5 should be at original state when testing without hydrostatic square pillow, in the state
Spring 5 be not intended to be stretching；Movable plate 4 is fixed in one end of measurement part, and the other end is directed at the aperture on top plate 3 and can
Partially extend through aperture.
When being tested after hydrostatic square pillow maintenance, hydrostatic square pillow is placed on pedestal 1, is made hydraulic
The top of tie respacer and the following table face contact of movable plate 4, then press the plunger-type fuel pump of hydrostatic square pillow, live so that top pushes
Movable plate 4 moves upwards, and due to being provided with spring 5 between top plate 3 and movable plate 4, spring can be made when movable plate 4 moves upwards
5 are in compressive state, and the spring 5 of compressive state can apply a downward active force to movable plate 4, if hydrostatic square pillow pushing tow
Effectively, then top can push movable plate 4 to overcome the downward active force of spring 5 and move upwards movable plate 4, movable plate 4
On measurement part can also move upwards and partially extend through aperture therewith, when measure part extension reach certain length after
(being usually advisable with stretching out 20~40mm) keeps ejection state 3~5 minutes of hydrostatic square pillow top, if it does not exist hydraulic oil
Leakage phenomenon then illustrates that hydrostatic square pillow maintenance result is good, and test finishes.
Under normal circumstances, the top of hydrostatic square pillow should withstand on the center of the lower surface of movable plate 4, can make to push up in this way
Power suffered by the various pieces of head is uniform, and the top of hydrostatic square pillow can withstand on activity when in order to make to test each time
The center of the lower surface of plate 4, it is preferable that the surface of pedestal 1 towards movable plate 4 is provided with places for adjusting hydrostatic square pillow 8
The limit plate 9 of position.There are many set-up modes for limit plate 9, such as are set as L-type, when placing hydrostatic square pillow 8, it is only necessary to will
Two perpendicular surfaces of hydrostatic square pillow 8 are fitted on limit plate 9.According to the of different sizes of hydrostatic square pillow 8,
The set position on pedestal 1 of limit plate 9 can also be adjusted.
In order to make top will not there is a phenomenon where slide when pushing movable plate 4, it is preferable that movable plate 4 is towards pedestal 1
Surface is provided with the annular groove of the top for placing hydrostatic square pillow 8.It should be understood that the various pieces in order to make top
Suffered power is uniform, and the center of the lower surface of movable plate 4 should be arranged in annular groove, in this way, when being tested,
Only the center for coming directly towards ejection in the lower surface of movable plate 4 need to will can be realized in the top merging annular groove of hydrostatic square pillow 8
Purpose.
Measurement part can be designed as diversified forms, for example, measurement part can be upper end and set graduated cylindrical rod, it can also
To be prism rod piece etc., in preferred embodiments of the present invention, measurement part includes pin shaft 6 and adjusting nut 7, pin shaft
6 one end is arranged on movable plate 4, and the other end of pin shaft 6 stretches out aperture, and adjusting nut 7 is arranged on the other end of pin shaft 6,
7 backstop of adjusting nut is in aperture.The benefit being arranged in this way is, when without experiment work, movable plate 4 can be in the effect of gravity
Under move downward, can prevent movable plate 4 is excessive to move downward in aperture by 7 backstop of adjusting nut, to guarantee spring 5
It is unlikely to stablize the elastic force for the spring 5 tested each time in the state being stretched.
Measurement part can be designed as the surface that its cross section is slightly less than movable plate 4, and certainly, the spring 5 being arranged so also needs
There are enough radiuses can be set on the outside of measurement part, when the elastic force of spring 5 is sufficiently large, is only needed according to above scheme
