How can we protect centrifugal pump?
How can we protect centrifugal pump?
By using an automatic flow control device, you can offer similar protection to the pump. Along with deadhead protection, centrifugal pumps should also be protected from runout, leading to cavitation. Runout also causes excessive currents, which will overheat the pump’s motor.
Which type of casing is used in centrifugal pump?
The three basic casing types primarily used for centrifugal pumps are the single volute, double volute and vaned diffuser.
What is the function of casing in centrifugal pump?
Pump casings serve to seal off the intside of the pump to atmosphere to prevent leakage and retain pressure. In the case of centrifugal pumps they surround the pump rotor which transmits energy to the fluid handled via the impeller(s) mounted on the rotating shaft.
Does centrifugal pump work without wear ring?
Wear rings play a crucial role in centrifugal pumps. A centrifugal pump typically features two adjacent wear rings: a stationary wear ring on the casing and a rotating wear ring on the impeller. The pump wear ring clearance between these two rings is critically important to a pump’s efficiency.
How do I protect my pump?
The most reliable way to protect your pump against dry running is to install external conductivity probe with a switch. This system shuts off the pump before the pump draws in air, providing 100% protection against damage.
Which is the type of casing?
There are five different types of casing pipe: Conductor Casing, Surface Casing, Intermediate Casing, liner String, Production Casing. Casing pipe is an integral part of the oil drilling and completion process.
What is vortex casing?
Vortex casing:- Vortex casing is a circular chamber placed in between the casing of the pump and the Impeller as shown in the above figure. Formation of eddies is reduced for the circular chamber and the loss of energy is reduced to a considerable amount.
What is casing wear ring?
Wearing rings are replaceable rings that are attached to the impeller and/or the pump casing to allow a small running clearance between the impeller and the pump casing without causing wear of the actual impeller or pump casing material.
What is a casing ring?
A ring fitted around the movement to fill the gap between the movement and the case .
