The working principle of the submersible vibrating pump, the working principle of the vibrating pump

Submersible pumps. There are several kinds, the wire package in the motor has oil invasion type and water invasion type, and it is dry type, you must read the manual before use, you can't make a mistake, you don't use it for a long time, you must turn the impeller before use, otherwise it will burn the bag because it is not stuck for a long time. The suction tube and pump must be filled with liquid before the pump is turned on.

After the pump is turned on, the impeller rotates at high speed, in which the liquid rotates along with the blades, under centrifugal force.

Under the effect, it flies away from the impeller and shoots outward, and the ejected liquid gradually slows down in the pump casing diffusion chamber, and the pressure gradually increases, and then flows out from the pump outlet and discharge pipe. At this time, a vacuum low-pressure area with neither air nor liquid is formed at the center of the blade because the liquid is thrown around, and the liquid in the liquid pool is at atmospheric pressure on the surface of the tank.

Under the effect, it flows into the pump through the suction pipe, and the liquid is continuously sucked up from the liquid pool and continuously flows out of the discharge pipe.

The suction tube and pump must be filled with liquid before the pump is turned on. After the pump is opened, the impeller rotates at high speed, and the liquid in it rotates with the blades, and under the action of centrifugal force, it flies away from the impeller and shoots outward, and the injected liquid gradually slows down in the pump casing diffusion chamber, and the pressure gradually increases, and then flows out from the pump outlet and discharge pipe. At this time, at the center of the blade, because the liquid is thrown around, a vacuum low pressure area with neither air nor liquid is formed, and the liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure on the pool surface, and the liquid is continuously sucked up from the liquid pool and continuously flows out of the discharge pipe.

Concrete vibrating machine is a kind of machine used in engineering construction, there are two kinds of eccentric and planetary type, and its vibration structure and working principle are: eccentric type: it is the rotating shaft with eccentric mass installed in the center of the vibrating rod, and the centrifugal force generated when rotating at high speed is transmitted to the vibrating rod housing through the bearing, so that the vibrating rod produces a circular vibration.

Planetary type: It is the use of a hollow rotating shaft at one end of the vibrating rod, when it rotates, the conical part of its lower end rolls along the conical surface in the rod shell, so as to form the planetary motion of the rolling element to drive the rod body to produce circular vibration.

The submersible pump is an important equipment for lifting water from deep wells, and the working principle of the submersible pump is as follows:

1. Before the submersible pump is opened, the suction pipe and the pump must be filled with liquid to prevent danger caused by different internal and external air pressures;

2. After the pump is opened, the impeller rotates at high speed, and the liquid in it rotates with the blades, and under the action of centrifugal force, it flies away from the impeller and shoots outward, and the ejected liquid gradually slows down in the pump casing diffusion chamber, and the pressure gradually increases, and then flows out of the pump outlet and discharge pipe;

3. In the center of the blade, because the liquid is thrown around, a vacuum low-pressure area with no mu of buried air and no liquid is formed, and the liquid in the liquid pool flows into the pump through the suction pipe under the use of liquid under the atmospheric pressure of the pool surface, and the liquid is continuously sucked up from the liquid pool and continuously flows out of the discharge pipe.

After the pump is opened, the impeller rotates at high speed, and the liquid in it rotates with the blades, and under the action of centrifugal force, it flies away from the Ye Zhimin wheel and shoots outward, and the ejected liquid gradually slows down in the pump casing and diffusion chamber, and the pressure gradually increases, and then flows out from the pump outlet and discharge pipe.

At this time, at the center of the blade, because the liquid is thrown around, a vacuum low pressure area with neither air nor liquid is formed, and the liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure on the pool surface, and the liquid is continuously sucked up from the liquid pool and continuously flows out of the discharge pipe.

When in use, the whole unit dives into the water to work, extracting groundwater to the surface, which is domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and can also be used for fountain landscape.

The working principle of the submersible pump is to use an electric motor to drive the impeller to rotate, so as to generate centrifugal force to suck water or other liquids into the pump body, and then transport the liquid to the place where it is needed through the outlet dust pipeline. Submersible pumps are usually installed in the water, so they can directly suck the Xiaoyinqiao liquid into the pump body without the need for additional suction pipes. The cable of the submersible pump is connected to the power supply through a sealed joint to ensure the safety and reliability of the circuit.

The structure of the submersible pump is compact and fierce, easy to install, reliable to use, and is widely used in various water conservancy projects and urban construction.

The submersible pump is an important equipment for lifting water from deep wells, and the working principle of the submersible pump is as follows:

1. Before the submersible pump is opened, the suction pipe and the pump must be filled with liquid to prevent danger caused by different internal and external air pressures;

2. After the pump is opened, the impeller rotates at high speed, and the liquid Zheng Xin's body rotates with the blades, and under the action of centrifugal force, it flies away from the impeller and shoots outward, and the ejected liquid gradually slows down in the pump casing diffusion chamber, and the pressure gradually increases in the middle of the bureau, and then flows out from the pump outlet and discharge pipe;

3. At the center of the blade, because the liquid is thrown around, a vacuum low-pressure area with neither air nor liquid is formed, and the liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure on the pool surface, and the liquid is continuously sucked up from the liquid pool and continuously flows out of the discharge pipe.

The working principle of the vibrating pump: after opening the pump, the impeller does high-speed rotation movement in the pump body (the pump body should be filled with liquid before opening the pump), the liquid in the pump body rotates with the impeller, and the liquid is thrown out by the impeller at the output under the action of centrifugal force, and the speed of the liquid thrown out gradually slows down in the pump diffusion chamber, after the liquid is thrown out, a vacuum low-pressure area is formed in the center of the impeller, and the liquid in the liquid pool flows into the pump through the suction pipe under the action of the outside atmosphere.

The volume of the pump diffusion chamber is constant, and as the liquid being thrown out increases, the pressure also gradually increases, and finally it is discharged from the outlet of the pump. In this way, the liquid is continuously sucked up from the tank and then continuously discharged from the pump outlet.

The power device generates vibration through the vibration motor and transmits it to the vibration device, which vibrates the concrete, makes the concrete dense and combined, and eliminates the honeycomb surface of the concrete, so as to improve its strength and ensure the quality of the concrete component.

Before turning on the pump, fill the suction pipe and pump with liquid. When the pump is turned on, the impeller is high.

Speed rotation, the liquid in it rotates with the blades, under the action of centrifugal force, flies away from the impeller and shoots out, the injected liquid gradually slows down in the pump casing diffusion chamber, the pressure gradually increases, and then flows out from the pump outlet and discharge pipe.

At this time, at the center of the blade, because the liquid is thrown around, a vacuum low pressure area with neither air nor liquid is formed, and the liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure on the pool surface, and the liquid is continuously sucked up from the liquid pool and continuously flows out of the discharge pipe.

A submersible pump is generally composed of a pump body, a lifting pipe, a pump base, a submersible motor and a starting protection device. Generally speaking, it is a kind of pump and motor combined into one to transport liquid machinery, it is simple in structure and easy to use.

According to the relative position of the pump and the motor, the submersible pump can be divided into upper pump type and lower pump type. The upper pump submersible pump is on the top and the motor is on the bottom, which greatly reduces the radial size of the pump, so it is mostly used for well submersible pumps and small operation submersible pumps. The lower pump type submersible pump motor is on the top and the pump is below, which is divided into two types: built-in and external.

The liquid conveyed by the built-in submersible electric pump first passes through the annular flow channel surrounding the motor, cools the motor, and then flows out of the pump pressure outlet. The range of applications for these pumps is expanding day by day, even when the suction tank is being drained close to the exhaustion of the suction tank, without worrying about the motor heating up. The externally installed submersible electric pump discharges the liquid directly from the pressurized water chamber behind the impeller or from the outlet of the guide vane, and the motor is also cooled by the pumped liquid.

Because the lower pump structure can work in shallow liquids, it is often used in submersible pumps on the working surface, especially it is the main structural type of large-diameter submersible pumps. The mechanical seal of the downpump submersible pump is located in the high-pressure area of the outlet water flow, the higher the head, the higher the water pressure here, so the performance of the mechanical seal is controlled by the head.

There are two kinds of submersible pumps, one is that the motor winding is directly immersed in the water, which drives the pump with a certain head. One is that the motor is waterproof and airtight, and the inside is filled with insulating oil to drive the pump to pump water.

The submersible pump is a centrifugal pump, before the pump starts, the pump and the inlet pipe are filled with water, after the pump is running, under the action of the centrifugal force generated by the high-speed rotation of the impeller, the water in the impeller flow channel is thrown around, pressed into the volute, the impeller inlet forms a vacuum, and the water of the pool is sucked in along the suction pipe under the external atmospheric pressure to supplement this space. The inhaled water is then thrown out by the impeller and enters the outlet pipe through the volute.

The centrifugal pump is called a centrifugal pump because the water is lifted to a high place under the action of the centrifugal force generated by the high-speed rotation of the impeller.

Talking about so many things, let's put it simply: The motor drives the impeller.

1. The working principle of centrifugal pump.

Before the pump starts, the pump and the inlet pipe are filled with water, after the pump is running, under the action of the centrifugal force generated by the high-speed rotation of the impeller, the water in the impeller flow channel is thrown around, pressed into the volute, the impeller inlet forms a vacuum, and the water of the pool is sucked in along the suction pipe under the external atmospheric pressure to supplement this space. The inhaled water is then thrown out by the impeller and enters the outlet pipe through the volute. It can be seen that if the impeller of the centrifugal pump rotates continuously, it can continuously absorb and press water, and the water can be continuously lifted from low to high or far away.

To sum up, the centrifugal pump is called a centrifugal pump because of the centrifugal force generated by the high-speed rotation of the impeller to lift the water to a high place.

1. The working principle of axial flow pump.

The working principle of axial flow pump is different from that of centrifugal pump, which mainly uses the thrust generated by the high-speed rotation of the impeller to lift water. The lift on the water as the axial pump blades rotate pushes the water from below to above.

The blades of axial flow pumps are generally submerged in a pool of water from which the source is sucked. Due to the high-speed rotation of the impeller, under the action of the lifting force generated by the blades, the water is continuously pushed upward, so that the water flows out along the outlet pipe. As the impeller rotates, the water is continuously pressed to a higher place.

1. The working principle of the mixed-flow pump.

Because the shape of the impeller of the mixed-flow pump is between the impeller of the centrifugal pump and the impeller of the axial flow pump, the working principle of the mixed-flow pump has both centrifugal force and lift, relying on the combined effect of the two, the water flows out of the impeller at a certain angle with the shaft, and the water is lifted to a high place through the volute chamber and the pipeline.

Due to its advantages of simple equipment structure, high efficiency, large displacement and high degree of automation, the electric submersible pump (ESP) oil production process is widely used in non-self-injection high-yield wells, high-cut wells and offshore oilfields, and has become one of the artificial lifting methods with stable production, high yield and good economic benefits, and is the main means of forced mining seepage and annihilation in the middle and late stages of oil exploitation cases.

The electric submersible pump has the characteristics of wide displacement head, large power, large production pressure difference, strong adaptability, simple surface technology, long unit life, convenient management and significant economic benefits, so it has been greatly used and has become the main force of offshore oil exploitation.

The electric submersible pump oil production system is mainly composed of two parts: downhole and surface.

Ground part: transformer, control cabinet, junction box.

Inoue safety valve.

Wellhead pans, Christmas trees, etc. Downhole plexus code punching part: power cable, multistage centrifugal pump, gas separator, motor, motor protector, single-flow valve, oil drain valve, downhole safety valve, etc.

The electric submersible pump motor, also known as the submersible motor, is the prime mover of the electric submersible pump unit, which is generally located at the lowest end. It is a three-phase squirrel cage asynchronous motor, and its working principle is the same as that of an ordinary three-phase asynchronous motor.

In the same way, it converts electrical energy into mechanical energy.

However, compared with ordinary motors, it has the following characteristics: the fuselage is slender, generally with a diameter of less than 160mm, a length of 5 10m, and some are longer, with a length-diameter ratio of up to; The shaft is hollow, which is convenient for circulating cooling the motor; If the starting torque is large, the rated speed can be reached; Inertia.

Small; , the gliding time is generally not more than 3s; Insulation rating.

High, insulating material mold search.

The combined effect of high temperature, high pressure and oil, gas and water; The inner cavity of the motor is filled with motor oil to isolate the well fluid and facilitate heat dissipation; There is a special isolation and sealing device between well fluid and motor oil, and a protector one by one. The structure of the submersible motor is composed of a stator, a rotor, a thrust bearing and an oil circulation cooling system.
