Know your Small Household Submersible Pump problem and the best pump solution

Pumps account for a considerable proportion of the manufacturing industry and are an important part of any place. The operation of the pump may cause various problems. The following are the common symptoms of Small Household Submersible Pump and the best pumping solutions for these symptoms.

If the pump has abnormal flow, it indicates a problem. If the drop is significant or the pump spends more time doing the same work, it may be caused by the collapse of the suction hose line. Otherwise, the gasket may be leaking, the suction pipe may be blocked or the impeller or wear plate may be damaged. If you are sure this is the problem, it is important to measure the discharge pressure and the suction vacuum. Compare these numbers with the initial readings during installation to find out if there are any abnormalities. If the discharge pressure is higher than the previous figure, the valve may be closed or blocked.

One of the most common pumping problems is noise. Usually, this means that the pump is cavitation, which may be due to the following reasons:

The suction lift is too high

The suction pipe is too long

Clogged or collapsed lining

Clogged filter

A combination of all these elements

Cavitation is not always extreme noise-sometimes it can be a bearing failure. It is important to identify whether the noise is mechanical or hydraulic noise. One option is to run the pump without water-if the noise disappears, it is mechanical, if not, it is hydraulic.

Pump overheating is related to the restricted flow of liquid into or out of the pump. Inappropriate gaps may also cause overheating, which may slow down the rate of reperfusion. However, there may be other issues related to recirculation-so wait until the pump has cooled down before checking the components.

If the pump leaks, use a vacuum gauge to test the tightness of the suction pipe, fittings, and pipe plug. It is important to ensure that these components are airtight. Use pipe paint to seal the threads and pipe plugs. If the vacuum gauge drops after shutdown, it means that atmospheric pressure enters the suction pipe, causing the pump to lose static lift. If worn, it can be solved by replacing the suction valve.
