Abstract
The utility model discloses a waterproof class of damping of pulsation ware, it has a damping cover, the damping hole of echelonment is equipped with in the axle center of damping cover, damping core pipe has been inserted to entry one end in the damping hole, the outer fringe of damping core pipe is close to damping hole entry one end and is equipped with the annular location shaft shoulder, be equipped with the expanded rubber circle at damping core pipe with the annular space that the damping cover formed, the circumference equipartition has a plurality of hole of permeating water on the pipe wall of damping core pipe, the front end external diameter of damping core pipe is less than the aperture diameter at damping hole middle part. The beneficial effects of the utility model are that: because the annular space who forms at damping core pipe and damping cover is equipped with the expanded rubber circle, the circumference equipartition has a plurality of hole of permeating water on the pipe wall of damping core pipe, produces pulsatory rivers and leads to the fact the impact through the pore pair expanded rubber circle that permeates water, can absorb the pulsation of rivers through the expanded rubber circle to effectively eliminate water flows the pulsation, ensures that water pressure is stable.
Description
Technical field
This utility model relates to a kind of damping unit, particularly to a kind of anti-current ripple damper.
Background technology
It is known that volume type rotor pump is made up of the rotor making beat motion in static pump case and pump case,
Energy is directly acted on liquid with static pressure form by the side contacted with liquid by the rotor in the pump housing, and borrows
The squeezing action drain of rotor, simultaneously at opposite side slot milling, forms low pressure, makes liquid inhale continuously
Enter.
Current owing to discharging when displacement pump works can produce bigger pulsation, causes its pressure transient, therefore
Needs are taked to cut down pulsation measure accordingly.
Summary of the invention
Technical problem to be solved in the utility model is to provide one can eliminate flow fluctuation, it is ensured that hydraulic pressure
Stable anti-current ripple damper.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of anti-current ripple damper, it has a damping sleeve, is provided with stair-stepping in the axle center of damping sleeve
Damping hole, is inserted with damping conductor pipe in entrance one end of damping hole, and the outer rim of damping conductor pipe enters near damping hole
Mouth one end is provided with the circular orientation shaft shoulder, is provided with foam rubber in the annular space that damping conductor pipe and damping sleeve are formed
Cushion rubber, is evenly distributed in several permeable holes on the tube wall of damping conductor pipe, and the front end external diameter of damping conductor pipe is little
Hole diameter in the middle part of damping hole.
As further preferably, the entrance and exit end at described damping hole is respectively equipped with female thread, and in institute
State the port of export and be threaded connection hydraulic quick coupler.
As further preferably, radially it is provided with stepped with connect in the middle part of described aperture in the middle part of damping sleeve
Installing hole, is used for installing Pressure gauge.
As further preferably, described location shaft shoulder outer rim and damping hole matched in clearance.
The beneficial effects of the utility model are: owing to setting in the annular space that damping conductor pipe and damping sleeve are formed
There is foam rubber circle, the tube wall of damping conductor pipe is evenly distributed in several permeable holes, produce the water of pulsation
Foam rubber circle is impacted by stream by permeable hole, can be absorbed the pulsation of current by foam rubber circle,
It is thus possible to effectively eliminate flow fluctuation, it is ensured that stable water pressure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: damping conductor pipe 1, the location shaft shoulder 101, permeable hole 102, damping sleeve 2, damping hole 201 is little
Hole 202, installing hole 203, foam rubber circle 3, hydraulic quick coupler 4.
Detailed description of the invention
As it is shown in figure 1, the one anti-current ripple damper that this utility model relates to, it has a damping sleeve 2,
It is provided with stair-stepping damping hole 201 in the axle center of damping sleeve 2, is inserted with resistance in entrance one end of damping hole 201
Buddhist nun's core pipe 1, the outer rim of damping conductor pipe 1 is provided with the circular orientation shaft shoulder 101 near damping hole 201 entrance one end,
The described location shaft shoulder 101 outer rim and damping hole 201 matched in clearance.
It is provided with foam rubber circle 3, at damping conductor pipe in the annular space that damping conductor pipe 1 and damping sleeve 2 are formed
Being evenly distributed in several permeable holes 102 on the tube wall of 1, the front end external diameter of damping conductor pipe 1 is less than damping hole 201
Aperture 202 diameter at middle part.Entrance and exit end at described damping hole 201 is respectively equipped with female thread, and
It has been threaded connection hydraulic quick coupler 4 at the described port of export.
The stepped installing hole 203 being radially provided with in the middle part of damping sleeve 2 and connect in the middle part of described aperture 202,
In the macropore of installing hole 203, it is provided with female thread, is used for Pressure gauge is installed.
During use, this anti-current ripple damper is connected to water by the female thread of damping hole 201 arrival end
Pump discharge end, connects drain pipe by hydraulic quick coupler 4, installs Pressure gauge on installing hole.Water pump is discharged
When unstable current flow through damping conductor pipe 1, by permeable hole 102, foam rubber circle 3 is impacted, logical
Cross foam rubber circle 3 and can absorb the pulsation of current such that it is able to effectively eliminate flow fluctuation, eliminate pulsation
After current successively in the middle part of damping hole 201 aperture and hydraulic quick coupler 4 discharge.
Although embodiment of the present utility model is disclosed as above, but it is not restricted to description and enforcement
Listed utilization in mode, it can be applied to various applicable field of the present utility model completely, for being familiar with
For those skilled in the art, it is easily achieved other amendment, therefore without departing substantially from claim and equivalent
Under the general concept that scope is limited, this utility model be not limited to specific details and shown here as with description
Legend.
