Detailed description of the invention
Below in conjunction with specific embodiment and Figure of description, the invention will be further described.Specific embodiment described herein
Only in order to explain the present invention, it is not intended to limit the present invention.
Embodiment: as it is shown in figure 1, high efficiency hydraulic ram, the conditioning chamber including the pump housing and being arranged on the pump housing, air chamber,
Connecting on the pump housing 19 and have conditioning chamber 20 and air chamber 21, inner chamber communicates；Described conditioning chamber 20 passes through flange with the pump housing 19
Connecting, junction is provided with drain valve assembly, and described drain valve assembly is by the valve rod 5 that sluices, drain valve 6 and drain valve seat 7 groups
Becoming, drain valve seat 7 is fixedly mounted on conditioning chamber 20 and the pump housing 19 junction, and sluicing valve rod 5 lower end is fixing connects drain valve 6,
On sluicing valve rod 5, kink drain valve seat 7, spring base 3 and hollow lead screw 2 the most successively, and described conditioning chamber 20 sets
Be equipped with corresponding through hole, sluicing valve rod 5 and hollow lead screw 2 is stretched out outside conditioning chamber 20 by one section of top by through hole, is sluicing
The top of valve rod 5 location nut 1 is fixed；Installing the first spring 4 on described spring base 3, the first spring 4 is enclosed within air silk
On bar 2, described hollow lead screw 2 is provided with positive stop lug boss 201, limits the first spring 4, with limit hollow lead screw 2
Eject outside conditioning chamber 20.
Described air chamber 21 and the pump housing 19 are by Flange joint, and junction is provided with blooming water valve assembly, and described pumps up water
Valve module is made up of the valve rod 16 that pumps up water, blooming water valve 13 and the valve seat 18 that pumps up water, and the described valve seat 18 that pumps up water is fixedly mounted on air
Room 21 and the pump housing 19 junction, valve seat 18 central axle sleeve that pumps up water is pumping up water on valve rod 16, and valve rod 16 top of pumping up water is fixing even
Connecing blooming water valve 13, the bottom of the described valve rod 16 that pumps up water is installed the second spring 15, spring shield 14 is hung by the second spring 15,
Spring shield 14 lower end is set with shift fork 12, in the middle part of the pump housing 19 above equipped with 11,12 and screw mandrel 10 of two guide posts,
Guide post 11,12 is connected with shift fork 12 with screw mandrel 10.It is also equipped with Pressure gauge 17 on air chamber 21, shows Indoor Air
Pressure, it is simple to check intraventricular pressure force value during regulation.When turn screw mandrel 10, shift fork 12 just makees translational motion, bullet at vertical direction
Spring cover 14 moves up and down under the common effect of the second spring 15 and shift fork 12, it is achieved to the compression of the second spring 15 and
Loosen control, thus realize the blooming water valve 13 regulation to valve seat 18 pressure size of pumping up water.
The control method of pump is as follows:
(1) injecting flowing water in pump, enter in pump from water inlet 22, unscrew location nut 1, turn sluicing valve rod 5 excites water hammer
Effect, allows pump startup.
(2) rotary screw rod 10 passes through fork 12 and the second spring 15 regulates the pressure that pumps up water and shows maximum to Pressure gauge 17.
(3) rotate sluicing valve rod 5, regulation drain valve 6 and the gap of drain valve seat 7, make bleeder quantity reduce, sluicing from
Discharge opening 24 is discharged, and major part water is raised up to air chamber by water hammer effect, and flows out from outlet 23.
(4) rotate hollow lead screw 2 and regulate sluicing pressure.
(5) repeating said process, until bleeder quantity is minimum or the amount of pumping up water is maximum, regulation work completes.
Lift is to be determined by user's field adjustable, can be shown by Pressure gauge 17, regulates by turn screw mandrel 10
The elastic force of two springs, such that it is able to make blooming water valve 13 obtain required unlatching pressure.In the pump housing, pressure everywhere of a certain moment
It is by force equal, but owing to the lifting surface area of blooming water valve 13 and drain valve 6 is unequal, so needing by regulation air silk
Bar 2 regulates the elastic force of the first spring 4, thus controls the closing force of drain valve 6.Last turn sluicing valve rod 5 is to suitable
Position, controls the gap between drain valve 6 and drain valve seat 7 so that the amount of pumping up water reaches maximum, or makes bleeder quantity minimize,
Screwed in place nut 1, stablizes the duty of pump.
When reaching optimal adjustment amount, the water yield of about 10% is discharged via the discharge opening of conditioning chamber, and the water yield of about 90% is passed through
Blooming water valve enters outlet.Owing to using this high efficiency hydraulic ram, in the case of other conditions are identical, the efficiency of pump can improve
About 10%, there is certain economic benefit.
It is preferred embodiment of the present invention in sum, all changes made according to technical solution of the present invention, the function produced
Protection scope of the present invention is belonged to when acting on the scope without departing from technical solution of the present invention.
