Have impact on the deficiencies such as the normal operation of production for the serious vibration of plunger pump in prior art, the technical problems to be solved in the utility model is to provide a kind of outlet of plunger pump vibration damper effectively can alleviating Oscillation Amplitude.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of outlet of plunger pump vibration damper of the utility model, be installed on outside outlet of plunger pump, with outlet of plunger pump pipeline connection, vibration damper intracavity section is greater than pipe section, is provided with damping block in chamber.
Described damping block is two, and in pipeline, liquid flow direction is horizontally set with and puts, longitudinal Heterogeneous Permutation, and one end is fixedly connected on vibration damper inwall, and the other end is unsettled.
It is elastic surface that described damping block meets liquid level, and vibration damper inwall and outlet of plunger pump pipeline inner wall are elastic wall.
Damping block is provided with multiple hole.
It is plane or arc elastic face that damping block meets liquid level.
Original outlet of plunger pump pipeline increases pipe-support, namely adopts intermediate support.
Rubber pad is provided with between pipeline and bearing.
Vibration damper and outlet of plunger pump pipeline are by Flange joint, and link place is provided with rubber washer.
Vibration damper liquid entering hole and liquid outlet are bellows interface.
The utility model has following beneficial effect and advantage:
1. the utility model is simple, practical, and vibration damping effect of easing stress is good, does not increase extra power consumption, protects pipeline, extends the working life of pipeline, saves maintenance cost.

Embodiment
Below in conjunction with Figure of description, the present invention is further elaborated.
Embodiment 1
As shown in Figure 1, a kind of outlet of plunger pump vibration damper of the utility model, be installed on outlet of plunger pump pipeline 1, with outlet of plunger pump pipeline connection, vibration damper intracavity section is greater than pipe section, is provided with damping block 3 in chamber.Vibration damper and outlet of plunger pump pipeline 1 are by Flange joint, and link place is provided with rubber washer.
In the present embodiment, vibration damper is cylinder-like structure, and it is axially axially vertical with outlet of plunger pump pipeline.The sectional area of meeting liquid level direction is greater than the sectional area of outlet of plunger pump pipeline, and outlet pressure and flow velocity are cushioned.Damping block 3 is elongated metal plate, it is two, each damping block 3 liquid flow direction in pipeline is horizontally set with to be put, longitudinal Heterogeneous Permutation, one end of one of them damping block 3 is fixedly connected on vibration damper upper inside wall, the other end is unsettled on one side, and another one end is fixedly connected on vibration damper inner wall lower, and the other end is on top unsettled.Pressure surge can guide on damping block 3 by this vibration damping structure, instead of directly clash into export pipeline inwall, cut down the impact of liquid stream by the elastics wing of damping block 3 free end, the balanced pipeline pressure at outlet of plunger pump place, make liquid levelling steady, the vibration of release the pressure fluctuation and pipeline.
Meanwhile, original outlet of plunger pump pipeline increases pipe-support, namely adopts intermediate support, be provided with rubber pad between pipeline and bearing, the flange connector place of vibration damper and outlet of plunger pump pipeline is equipped with rubber washer, to prevent because wearing and tearing appear in vibration
Embodiment 2
Be with the difference of embodiment 1: it is elastic surface that damping block 3 meets liquid level, vibration damper inwall and outlet of plunger pump pipeline 1 inwall are elastic wall.
