What's the difference between a double suction pump and a single suction pump?
The 3 floor of a friend, the next time you quote us the trouble to answer, please indicate the source, at least to keep integrity! Now on the market a variety of micro pump, micro pump, micro pump, high pressure micro water pump, liquid sampling pump, small pump, self suction pump, DC pump, diaphragm pump, whether has the function of self suction, mainly refer to the following two points: 1. means: self suction pump suction pipe is in the air, using form a negative pressure pump at work (vacuum), under the influence of the atmospheric pressure will be lower than the water pumping port, then discharged from the pump discharge end. Before this process, there is no need to add "diversion water". The pump with this capability is called a self suction pump". 2., some centrifugal or rotary vane pump, before absorbing water, you must add "water diversion" in the pump cavity to form a closed environment, and then pump operation to form negative pressure, to achieve the purpose of water absorption. For example, a manual pump used in rural areas. No self-priming capacity of the pump, each time before adding water to add "water" is very troublesome. 3., suction level, with the pump power, flow, structure and so on, but the general micro pump self-priming process is not easy to do higher
The difference between a single suction pump and a double suction pump is that the double suction pump has two intake ports, while the single suction has only one intake.
From the literal sense to understand, double suction pump is the impeller at both ends of the water inlet, and the single suction pump is from the impeller at one end of the water.Dual suction is mainly used in the process of large flow and low lift. When the pump flow is greater than or equal to 280m3/h, the caliber of 200mm or more, if the use of a single suction pump, then the speed requirements of about 1450rpm in order to achieve the suction requirements. However, if the double suction pump is used, the size and weight of the pump are reduced, and the speed can be increased, the volumetric efficiency is increased, and the reliability of the equipment is improved.Single suction pump, also known as end suction pump, single suction pump flow is relatively small. The same flow, single suction of small size, but the axial force, bearing a large burden. The cost of single suction pump is low, the price is reasonable, widely used, but in many ways it is not as good as double suction pump. If the inlet pressure is higher, the general choice of double suction wheel can be solved. Because the axial force balance of the impeller of the single suction pump is a big problem.
