A single suction pump having its suction nozzle on the opposite side of the casing from the stuffing box and having the face of the suction nozzle perpendicular to the longitudinal axis of the shaft
To compensate high suction volume during startup of he pump. the reducer area below the pipeline at the suction stores excess volume of fluid.
Yes refrigerant temperatures and pressures in the cooling mode of a heat pump is the same. They are both in the suction side and the discharge side of the system.
this is overhang centrifugal pump . the suction drum level , suction strainer and suction pipings were all checked and found OK
if we use concentric reducer at suction of pipe ,due to high turbulence flow of fluid ,some vapour pressure generate which generate bad effects on impeller of pump ,which decrease pump efficiency , so to avoid this problem the eccentric reducer's use in pump suction
It is common practice to specify the pump suction line one size larger than the pump discharge line in order to increase the Net Positive Suction Head available (NPSHA) to the pump. A smaller suction line the same pipe size as the discharge line would result in more pressure drop in the suction line and reduce the amount of head available to the suction side of the pump. This in turn would result in an operating point closer to cavitation of the pump.
A suction milking machine is divided into two different parts one side is the milking side the other is the pulsator side. When the machine is turned on a vacuum pump removes air for the system everywhere when it is not on the vacuum be the same on both the milking aide and the pulsator side.
Two of the most common causes of pump cavitation are air in the pump or the fluid being pumped is too hot. Water at 180 degrees will cause the pump to cavitate (steam bubbles form in the eye of the pump on the suction side of the impeller) because of the drop in pressure created on the suction of the pump. This can be corrected by either pumping cooler water, or by raising the net suction head of the pump. Air in the pump can be corrected by venting the pump.
what is th different between end suction pump and singl stage pump and multistage pump
Discharge side........
t
when pressure on the suction side of the pump drop below the vapour pressure of the liquid, vapour forms. It's caused because of insufficient suction head, high suction lift, excessive friction head, or high liquid temperature.
