Analyze the main differences between submersible pumps and centrifugal pumps
2017-08-30
Yutong Pump Industry specializes in the production of various pump products, including submersible pumps and centrifugal pumps. Submersible pumps and centrifugal pumps are widely used pump valve products in our daily lives. Yutong Pump Industry introduces the differences between these two types of pumps as follows. (1) Submersible pumps and centrifugal pumps have different working principles. Working principle of submersible pump: Before starting the pump, the suction pipe and the inside of the pump must be filled with liquid. Before starting the pump, the suction pipe and the inside of the pump must be filled with liquid. After starting the pump, the impeller rotates at high speed, and the liquid inside rotates with the blades. Under the action of centrifugal force, it is ejected from the impeller. The ejected liquid gradually slows down in the diffuser of the pump casing, and the pressure gradually...
Yutong Pump Industry specializes in the production of submersible pumps, centrifugal pumps, and other types of pump products. Submersible pumps and centrifugal pumps are widely used pump valve products in our daily lives. Yutong Pump Industry introduces the differences between these two types of pumps below.
(1) Submersible pumps and centrifugal pumps have different working principles.
Working principle of submersible pump: Before starting the pump, the suction pipe and the inside of the pump must be filled with liquid. Before starting the pump, the suction pipe and the inside of the pump must be filled with liquid. After starting the pump, the impeller rotates at high speed, and the liquid inside rotates with the blades. Under the action of centrifugal force, the liquid is thrown outward from the impeller. The velocity of the ejected liquid gradually slows down in the diffuser of the pump casing, and the pressure gradually increases. Then, it flows out from the pump outlet and discharge pipe. At this time, a vacuum low-pressure area without air or liquid is formed at the center of the blades because the liquid is thrown to the surroundings. Under the action of atmospheric pressure on the surface of the liquid pool, the liquid flows into the pump through the suction pipe. The liquid is continuously drawn up from the liquid pool and continuously flows out from the discharge pipe.
Working principle of centrifugal pump: The impeller is installed inside the pump casing 2 and fastened to the pump shaft 3. The pump shaft is directly driven by a motor. There is a liquid suction port 4 in the center of the pump casing, which is connected to the suction pipe 5. The liquid enters the pump through the foot valve 6 and the suction pipe. The liquid discharge port 8 on the pump casing is connected to the discharge pipe 9.
(2) The essential difference between submersible pumps and centrifugal pumps
A submersible pump is a widely used water treatment pump product. Before starting the pump, the suction pipe and the inside of the pump must be filled with liquid, so it is necessary to choose a suitable foot valve.
Centrifugal pumps mainly have single-stage single-suction, multi-stage single-suction, and single-stage double-suction design structures, and there are pipeline type, submerged type, self-priming type, and submersible type. The main components of a centrifugal pump are the impeller, pump casing, and shaft seal device. The function of the impeller is to directly transfer the mechanical energy of the prime mover to the liquid to increase the liquid's static pressure energy and kinetic energy (mainly increasing static pressure energy).
