    KCB gear pump caliber impact on pump head and motor loads
    KCB gear pump selection process, choose the pump caliber are generally ignored , more often is the first to determine the lift and flow . But caliber pump for pump head and motor load is going to affect .
    KCB gear pump caliber impact on lift :
    Large-diameter pipe with a small pump pumping a lot of people think that this can increase the actual head , in fact, the actual lift pump lift ~ = total loss of lift . When the pump model to determine the total lift is certain ; loss of lift mainly from the pipe resistance , the smaller the diameter Obviously the greater the resistance , and thus the greater the loss of lift , so the reduced diameter, the actual lift pump not only can not increase , but will reduce , resulting in decreased efficiency of the pump . Similarly, when a small pump with a large diameter pipes pumping , it will not reduce the actual lift pump , but will reduce the resistance of the pipeline due to a loss of lift is reduced , so that the actual head increased.

    KCB gear pump caliber impact load on the motor :
    A lot of people think that when a small pump with a large diameter pipes pumping bound to greatly increase the electrical load , they think the diameter increases, the pressure of the water in the outlet pipe of the pump impeller is large, and thus greatly increase the electrical load . As everyone knows , the size of the liquid pressure and head level only , but not to the size of the pipe cross-sectional area . A long head , the pump impeller dimensions remain unchanged , regardless of how the diameter , the pressure acting on the impeller are fixed. After just a pipe diameter increases, the flow resistance will be reduced, leaving the flow rate increases, power consumption is also appropriate to increase . But as long as the nominal head range , regardless of how the increased diameter of the pump is working properly , and also can reduce piping losses and improve pump efficiency.
