Issues with the current in centrifugal pumps? (Seeking advice on how to choose a pump and a motor?) ）
Thread Content
I have been driving the vehicle for almost 3 years now; I have 2 centrifugal pumps, each used in a different tower, and their main function is to facilitate circulation. Currently, the outlet of one of these pumps (the water washing pump) is set at a wide opening, yet the current flow is low. The outlet of the second pump is set at a narrow opening, but the current flow is high Their two motors are the same. I would like advice on how to choose a pump and the appropriate motor Could a Haiyou help analyze this?
What is the rated current of the pump? If the current is too high, the pump should be considered.
To determine whether the current level is high or not, first check if the pumps are identical; if the parameters of the pumps differ, the current levels will naturally vary as well. If the parameters of the pump are exactly the same but the current is different, then there is a problem with the pump or the pipes and other related components. The question you asked is not specific at all~
When selecting a pump, it is necessary to determine the flow rate and head you need, as well as the specific properties of the material to be pumped, including its specific gravity. Then calculate the pump shaft power. The shaft power of the pump, multiplied by the specific gravity of the material, can be used to determine the size of motor that should be selected for the pump.
Are the motor and coupling concentric?
