Reasons for the decline in the efficiency of the double suction pump:

Reasons for the decline in the efficiency of the double suction pump:

1. Due to the initialization of the water flow, the inner wall of the pump flow channel and the impeller passing through the water surface become rough and uneven, the friction coefficient of the flow channel in the pump increases, and the flow rate of water in the pump is very large, and the head loss increases. Hydraulic efficiency is reduced.

Structure of segmented multistage centrifugal pump

Structure of segmented multistage centrifugal pump

When the pressure is high, a multistage centrifugal pump is usually used. This pump is a vertically split multistage pump, which has a front section, a tail section and several middle sections connected as a whole by four long rod bolts. The number of impellers installed on the pump shaft represents the number of stages of the centrifugal pump. Each impeller in the middle section is equipped with a seeking wheel. The function of the seeking wheel is basically the same as that of the volute, mainly to convert kinetic energy into static pressure energy. The impeller is generally single-suction, and the suction port faces one direction.

Notable Features of Double Suction Pumps

Notable Features of Double Suction Pumps

Double suction pumps have the following notable features: First, it is equivalent to two single-stage impellers of the same diameter working at the same time, and the flow rate can be doubled under the same outer diameter of the impeller. Therefore, the flow rate of the double-suction pump is larger.
