How to adjust mechanical seals for submersible sand pumps?

Submersible dredge pump, also known as submersible sediment pump, submersible mud pump, submersible sand pump, submersible suction pump, submersible pump, underwater dredging pump, etc., China Do Pump is a manufacturer of sand pump. dredge pump, electric submersible sand pump and hydraulic submersible dredge pump with relative dredging equipment.

After the mechanical seal of the submersible sand pump is installed and debugged, it is generally necessary to perform a static test to observe the leakage. If the leakage is small, the sand pump is mostly a moving ring or a static ring seal. When testing the flow rate using orifice plates and nozzles, standard orifice plates and nozzles that meet the requirements should be used.


1.The inner surface of the measuring submersible pumping pump tube should be clean, free of pits and deposits, and at least within the length of the upstream 10D and the downstream 4D of the throttling.


2.When the temperature of the measuring fluid exceeds the normal temperature range, the measuring pipe section and flange of the submersible sand pump should be insulated at least on the entire straight pipe section required.


3.Submersible sand pump, except for 2D from the throttle, the pipe between the throttle and an upstream resistance or spoiler can be composed of one pipe segment or several pipe segments.


As long as the misalignment between any two pipe sections does not exceed 0.3%, the flow coefficient has no additional uncertainty. If the misalignment between any two pipe sections exceeds 0.3% D, but the above relationship is satisfied Then the uncertainty of the flow coefficient should be arithmetically added with an additional uncertainty of ± 0.2%; if the misalignment is greater than the limit given above, the installation does not meet the requirements of this standard.
