Vibration and noise holes owing to road

how to deal with pit pump pipe vibration and noise of the road?

another kind of defect is hydraulic line pipe vibration and noise, especially the article number of the line in a together. Responsible for such defect and cleaning methods are as follows.

1, the oscillation tube oil column. Pipe can be altered the length of the body to change the natural oscillation frequency of the oil column in the pipe series damping can avoid and reduce the oscillation.

2, tube into the air, vibration and noise.

3 and return pipe minister oscillation. When the tubing is not smooth, the back pressure big, or device in the return pipe blocked filter, cooler, to reduce the back pressure and return hose should be thick, short, when mounted on the back to the oil filter or the water cooler, to avoid oil return not free, but another one branch. In oil filter or blocked, cooler oil return can pass back pressure valve short circuit to the fuel tank, avoid oscillation at the tongue.

4, as far as possible to cut holes owing to sharp bend in the road, suddenly big or thin, as well as add the pipe wall thickness, can reduce vibration and noise.

5, water pump piping or a hole in the ground under the condition of fixed sand, such as the male two pump discharge is very close to join the overflow with a tee joint total row, this kind of line can produce eddy current, noise caused by pipeline, the direction of the dramatic change of vortex and other vortex flow confluence, vibration and noise, the method is to export pump and valve outlet pressure sharply change the confluence of both piping can't too close, appropriate spin interval, can avoid the noise. Solution is to share a pressure relief valve or two valve widening some difference. Other, return pipe delimited, and properly increase the pipe diameter.

6, the orientation of the vibration and noise in simple concatenated a short flexible pipe, to falling sound effect is significant. To avoid oscillation, this method is often in the string of lee pick a small flexible tube is applied, when there is no point to the attenuation of high frequency oscillation is effective.

7 and wall oscillation. Avoid pit pump has a narrow pa and a sharp bend, as little as possible with the elbow. Need to use elbow, bend radius should be as far as possible.
