In normal conditions, when the high-pressure cleaning pump is in normal operation state, the high pressure cleaning pump will only make a very small sound. And if there's a lot of noise, it's probably due to some problems with the equipment. With the response of user friends, when using high-pressure cleaning pump, it was found that after a period of time, the noise of high-pressure cleaning pump increased much more than that just bought. So, what is this about, for this problem, as a dosing metering pump manufacturer, we think that it can be handled from two aspects. Therefore, if we find the problem of noise increasing in the use of high-pressure cleaning pump, we should first consider whether or not the impeller in the equipment is changed regularly. If we have not changed the impeller for a long time, then we can replace a impeller, if this is the problem, then the noise will naturally reduce.

If it is not the above reason, then we need to consider whether it is due to the problem of the check valve. At this time, we reinstall the check valve. If this is the case, then the noise problem of the high pressure cleaning pump will be significantly reduced after the reinstallation.

In fact, if the noise of the high-pressure cleaning pump is found to be bigger, it is likely to be the two aspects of the problem. That is to say, on the one hand, it is due to the wrong way of cleaning the impeller at ordinary times, causing the deformation of the impeller, and thus the problem of the imbalance of the equipment's dynamic balance appears. Or because the installation of the impeller is not reasonable, resulting in no good coordination with the motor shaft, resulting in noise. On the other hand, it may be that the installation of the valve is not reasonable, and there is a problem of card death, which causes the noise to become larger.

In a word, if we have encountered this problem in the future work, we may refer to the above two aspects of the reasons to deal with. Of course, we also need to combine the actual use of high pressure cleaning pumps to consider.
