Single-side inlet pump: also called single-suction pump, that is, there is only one water inlet on the impeller; 2. Vertical pump: the pump shaft is in the vertical position. Multi-stage pump: that is, there are two or more impellers on the pump shaft. Single-stage pump: that is, there is only one impeller on the pump shaft. 3. Before starting, you need to fill the pump casing and suction pipe with water, and then drive the motor to make the impeller rotate at high speed.

Classification according to the way of impeller discharge 1. Classification by the number of impellers 1. Suction centrifugal pump (non-self-filling centrifugal pump): the pump shaft is higher than the surface of the suction pool. The water is thrown out of the impeller by centrifugal force, and negative pressure is formed in the center of the impeller. At this time, the total head of the pump is the sum of the heads produced China beer brewhouse by n impellers.  Classification according to the combination of pump casing 1. Guide vane pump: After the water comes out of the impeller, it enters the guide vane set outside it, and then enters the next stage or flows into the outlet pipe.

Volute pump: After the water comes out of the impeller, it directly enters the pump casing with a spiral shape. Vertical joint surface pump: the joint surface is perpendicular to the axis line.  Double-side inlet pump: also called double-suction pump, that is, both sides of the impeller All have an inlet.  Classification according to the impeller suction method 1. Low pressure pump: pressure lower than 100 meters water column; 2. The water in the suction pool enters the impeller under the action of atmospheric pressure.

It is also affected by the high-speed rotating impeller and is thrown out of the impeller into the pressurized water pipeline. Horizontally split pump: that is, there is a joint seam on the horizontal plane passing through the axis line. Centrifugal pumps are divided into many types. Classification by working pressure 1. Classification by installation height 1. Medium pressure pump: pressure between 100 and 650 meters water column; 3. Classification by pump shaft position 1. 2.We know that centrifugal pumps work by using the rotation of the impeller to make the water produce centrifugal movement.

Its flow rate is twice that of a single-suction pump, which can be roughly regarded as two single-suction pump impellers placed back to back together. High pressure pump: pressure higher than 650 meters water column. Let's learn about the types of centrifugal pumps in detail below. 2. 2. Nowadays, centrifugal pumps are also very popular and well-known by people. Horizontal pump: The pump shaft is in a horizontal position. 2. Self-filling centrifugal pump: The pump shaft is lower than the surface of the suction pool, and it can be started automatically without watering when starting
