Working principle of horizontal split case pump
The split case pump is also called a single stage double suction centrifugal pump. Horizontal Split Case Double Suction Centrifugal Pump main function is to transport medium with large flow rate, such as clean water or other liquids with physical and chemical properties similar to water. Due to its unique structural design, this pump can effectively increase the flow rate and efficiency of the pump while reducing energy consumption.
Working principle of double suction split case pump
How does a double-suction split case pump deliver water to a high place? When the pump is filled with water and the impeller rotates, the water will fly outward at high speed due to the centrifugal force. The water that flies outward is collected in a container called a pump casing and led to the outlet. In this process, the high-speed rotating water becomes high-pressure water and is pressed to a high place. To pump up the water from a low place, the following is done: in the pump casing, when the impeller rotates, the water flies outward due to the centrifugal force, and the pressure in the center of the impeller drops, thus forming a "vacuum". In this way, although the water suction surface is located below the pump, the pressure is higher due to the atmospheric pressure, and the water is pressed upward, so the water is pumped up.
How does a double-suction split case pump work specifically? The impeller is installed in the pump casing and fastened to the pump shaft. The pump shaft is connected to the motor through the coupling technology. The operation of the motor drives the pump shaft and the impeller to rotate. There is a liquid suction in the middle of the pump casing connected to the suction pipe. The liquid enters the pump through the bottom valve and the suction pipe. The liquid discharge port on the pump casing is connected to the discharge pipe. Before starting the water pump, the pump casing and the suction pipe must be filled with water, and then the motor is started to make the pump shaft drive the impeller and water to rotate at high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller and flows into the water pressure pipeline of the water pump through the flow channel of the volute pump casing.
Advantages of double suction split case pump
High efficiency: Due to its compact structure and optimized double-suction impeller, the axial force is reduced to a minimum, and the inner surface of the centrifugal pump casing and the impeller surface have anti-cavitation properties, thus ensuring that the pump has high efficiency and low energy consumption during operation.
Large flow: The design of the double-suction split pump has two suction ports, each of which can bear half of the flow, which reduces the inlet flow rate at the same speed and flow, and the impeller is not prone to cavitation. The double-suction design enables the pump to handle a larger flow and is suitable for occasions with large flow requirements.
Easy to maintain: The joint surface between the pump body and the pump cover is usually a horizontal plane passing through the axis centerline. This structure does not require the removal of the inlet and outlet pipes and the motor during maintenance. You only need to open the pump cover to remove the rotor for maintenance, which greatly facilitates maintenance work.
Application of double suction split case pump
The horizontal split case double suction centrifugal pumphas a wide range of applications, and is suitable for water supply and drainage in factories, mines, cities, power stations, farmland irrigation and drainage, and various water conservancy projects. It can transport clean water or liquids with physical and chemical properties similar to water, and has the characteristics of high efficiency, energy saving, stable operation, safety and reliability.
