To bring it into line with the principles of economy, safety and application. The reliable operation of the medium-open pump determines the normal operation of the industrial production system, we can also assist in the operation of the pump in a series of things. In the operation of the medium-open pump by performance differentiation into three data, small flow and high lift, medium flow and medium lift, large flow and large lift. It should be noted that in these three kinds of performance, to avoid the pump long-term operation under small flow and large lift, so that the pump will produce a vortex, vortex will produce a large thrust, so that the shaft bending deflection is too large, not conducive to continuous operation. In the rotating component lubrication efforts, the rotary components of the pump have bearings, shafts and other forms, to ensure their lubrication, regular inspection of lubricants, check the amount of oil, oil can not be too little, not too much, oil quality is also very important, when the oil spoilage to be replaced in a timely manner. The pump group for planning management, the operation of the pump and maintenance of the installation rules and regulations, so that the temperature is not exceeded, the speed of operation is not speeding.

Bushing composition, shaft parts using flat keys and round nuts fixed, locking, so that it becomes one, the entire rotor by the two ends of the bearing support. The impeller of the medium open pump transmits the energy of the original motive through the action of centrifugal force to the liquid in the pump, which increases the speed and pressure of the liquid, causes the liquid in the pump to drain out, and the liquid in the inlet pipe is sucked in. The medium open pump impeller is installed in the pump shell and fastened to the pump shaft, and the pump shaft is directly driven by the motor. The pump shell has a liquid connected to the tube. The liquid enters the pump through the bottom valve and tube. The liquid outlet on the pump shell is connected with the discharge pipe. When the speed of the pump is certain, its pressure head, the flow rate is related to the impeller diameter. The shape of the impeller blade of the middle open pump lies in the accord with the flow law. The motion law of liquid in impeller should be studied first. In order to study the flow law of liquid in the impeller, we take the liquid flow in the impeller from the front cover to the back cover to the hard layer, each layer of phase method on a flow surface. The liquid flows only along each layer, and the liquid of the layer and layer does not mix with each other.
