KCB gear pump caliber impact on pump head and motor loads
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.
