Functional characteristics of pipeline centrifugal pump and the submersible pump

Submersible pump can be put under water, centrifugal pump on the ground, the size should be their connection pipe diameter.

1 submersible pump

Water processing tools, a very wide range of uses. Different from the ordinary pumping machine is it works under water, and pumps most of the work on the ground.

Submersible pump works

Before opening the pump, suction pipes and pumps must be filled with liquid. Open pump, the impeller rotating speed, which leaves the liquid together with the rotation, under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the proliferation of indoor speed, the pressure gradually

Gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, the blade center due to the vacuum area of low pressure liquid was thrown into the surrounding formed neither air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, liquid

Is continuously pumped up from the liquid pool is also a continuous outflow from the discharge tube.

The basic parameters of submersible pumps

Including flow, head, pump speed, supporting power, rated current, efficiency, diameter and so on

Submersible pump is the main purpose and scope

Including the construction schedule, water, agricultural irrigation, industrial water cycle, urban and rural residents drinking water supply, and even disaster relief and so on

2 centrifugal pump

What is the centrifugal.

Centrifugal is actually inertia performance. Like drops of water on the umbrella, when the umbrella slowly rotates, water droplets will follow an umbrella rotation, this is because the friction umbrella and water drop for droplets of centripetal force of nature. But if an umbrella rotation speed, the friction is not enough

To drop in a circular motion, then the drop will be from the outside edge of an umbrella movement. Like a rope pulling the Stone moving in a circle, if the speed is too fast, the rope will break, stones will fly out. This is the so-called centrifugal.

Centrifugal pump is based on the design principles of the high-speed rotation of the impeller blades. Rotate driven water, water throw, so as to achieve the purpose of transportation.

Centrifugal pumps have many kinds. From the use can be divided into commercial and industrial pumps, from the transmission media can be divided into the water pump, pump impurities and corrosion resisting pump.

The basic structure of the centrifugal pump is composed of six parts, respectively is: the impeller, pump body, pump shaft, bearings, seal rings, stuffing box.
