Detailed description of the invention
With reference now to accompanying drawing, embodiment of the present utility model is described.
Embodiment 1
Detailed description of the invention of the present utility model is if Fig. 1 is to shown in 8.A kind of for installing plunger displacement pump
Device, including power multiplying cylinder 1；Power multiplying cylinder 1 is provided with clamping piston 3；Clamping piston 3 is for be driven by oil pressure
Dynamic piston.
Power multiplying cylinder 1 is provided with cavity 5, and wherein one end of clamping piston 3 is positioned at cavity 5.Cavity 5
Sidewall be provided with an annular recess, equipped with sealing ring 17 on this groove.This sealing ring 17 is O
Type circle.Sealing ring 17 between clamping piston 3 and cavity 5, play prevent oil in cavity 5 from
The effect that gap between the two spills.
Hole 4, a location it is respectively equipped with at four angles at power multiplying cylinder 1 edge.Hole 4, location can allow a times power
Cylinder 1 is enclosed within four butt cap screw rods 6 of plunger displacement pump.This device also includes that four are installed nut 2, install
Nut 2 for being tightened in four butt cap screw rods 6 by power multiplying cylinder 1.
The quantity of clamping piston 3 is one, and this clamping piston 3 is positioned at the geometric center of power multiplying cylinder 1.
Direction contrary with clamping piston 3 on power multiplying cylinder 1 has hydraulic oil input, hydraulic spanner 15
And it is connected by a hydraulic tube 18 between the hydraulic oil input on power multiplying cylinder 1, hydraulic tube 18 energy
