High-pressure self-balancing corrosion multistage pump head, flow rate and the relationship between the impeller diameter

High self balancing corrosion multistage pump lift and flow rate and the relationship between the impeller diameter:

high pressure self balancing corrosion law of multistage centrifugal water pump cutting: ( H1：H2) ^ 2 = D1: D2Q1: Q2 = D1, D2 and it can be seen that the diameter of the impeller and is proportional to the square of the head, is proportional to the flow. The more the greater the impeller diameter head, flow, because the water out depends on the impeller rotates at a speed of the centrifugal force and tangent linear velocity, the larger the diameter, the greater the centrifugal force and linear velocity.

high self balancing corrosion multistage pump impeller and the relationship between the lift:

high-pressure self-balancing corrosion multistage water pump head size depends on the structure of the pump, such as the size of the impeller diameter, blade bending, rotational speed, etc. From the center line of the pump impeller to the height, the vertical surface of the pool that can pump up to the height of the water pressure, called water head pressure, pressure range for short.

of suction lift pump head = + pressure water head, it should be pointed out that lift nameplate marking refers to the pump itself can produce lift, it does not contain water pipe head loss caused by friction. When choosing pumps, attention should not be neglected. Otherwise, can't will spring up.

high self balancing corrosion multistage pump with the impeller diameter, the greater the impeller, the greater the head, and vice versa. It doesn't make much difference whether traffic and impeller diameter. Rated conditions, the greater the head, the smaller the flow, is inversely proportional to.

high pressure determination of self-balancing corrosion multistage pump note:

pump lift can be determined through experiment, namely in the pump inlet to a vacuum gauge, the exit to a pressure gauge, excluding the two table section on the kinetic energy of the poor ( The Δ u2/2 g = 0) Without considering the energy loss between the two tables section ( ∑ f1 - namely 2 = 0) , the pump lift available under calculation.

pay attention to the following two points:

1, the type of p2 for the pump outlet pressure gauge reading ( Pa） ; P1 for the pump inlet vacuum gauge readings ( Negative gauge pressure value, Pa) ;

2, pay attention to distinguish between centrifugal water pump lift ( Head) And the height of the rally in two different concepts.

high self balancing corrosion multistage pumping water, the relationship with the vacuum degree:

high self balancing corrosion multistage pump is pumping by centrifugal force, idling will burn out without water. Vacuum in vacuum pump or a secondary vacuum vacuum method. High pressure self balancing corrosion of multistage centrifugal pump suction vacuum consists of three parts ( Establish, inhaled liquid surface to pump the entrance equation can get)

, on the suction height, this has nothing to do with the traffic;

2, the loss of the suction device, and is proportional to the square of the flow;

3, to set up the pump at the entrance to the kinetic energy of the head, and is proportional to the square of the flow;

with the second and the third is proportional to the square of the flow, so the pump inlet vacuum degree increases with the increase of the traffic.
