What else can I help you with?
Why there is Sever cavitation sound at the pump suction for the A pump while there is no problem at the B pump which is operating in parallel with this pump.?
this is overhang centrifugal pump . the suction drum level , suction strainer and suction pipings were all checked and found OK
What is the difference between end suction pump and horizontal multi stage pump?
what is th different between end suction pump and singl stage pump and multistage pump
What is the meaning of end suction of pump?
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
What is the suction pressure of condensate extraction pump?
Condensate pump suction pressure below 4 feet of the condenser is almost equal to condenser pressure (760mm of Hg). If the pump equiped under the deep pit , suction pressure is vary.
Why is the suction line of a pump larger than the discharge line?
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.
Why flat side up reducer is used at pump suction?
To compensate high suction volume during startup of he pump. the reducer area below the pipeline at the suction stores excess volume of fluid.
What is a double pump?
what is the meaning of double suction
What is negative suction in pump?
Negative Suction Head means the pump is drawing liquid up from below its centerline. The distance between the centerline of the pump and the surface of the fluid is measured in head feet, this can be negative (below the pump) or positive (above the pump).
Does the pump go to the bottom of the tank as have no suction pads?
If the pump does not have suction pads, it typically won't reach the bottom of the tank on its own, as suction pads are designed to create a seal and ensure proper operation. Without these pads, the pump may not maintain adequate suction, leading to inefficient performance. Depending on the pump design, it may need to be positioned manually at the desired depth for effective operation.
If suction valve of the centrifugal pump being closed in running what will be a effect?
It will damage the pump.
What is the function of an eccentric pipe reducer in the suction side of a pump?
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
What is the possible cause of pump cavitations?
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.
