Product Description:

  Vertical Submersible Axial Flow / Mixed Flow Water Pump for Storm Station

1.Structure of Vertical Submersible Axial Flow / Mixed Flow Water Pump for Storm Station

QZB Axial Flow pump is the new upgrated product of the tradition ones. they are used in applications that require very high flow rates and very low amounts of pressure (head). They are useful as circulating water pumps in power plants. They’re also commonly used in the chemical industry for circulating large amounts of fluids in evaporators. And they are useful in flood dewatering applications where large quantities of water need to be moved a short distance, such as over a levee or dyke. These applications are not nearly as common as applications for radial flow pumps, so there are not nearly as many axial flow pumps as there are radial flow pumps. QZB axial flow pump is combined of pump and submersible motor parts. Pump mainly contains sectional bell, impeller, impeller casing, and diffusor. And the submersible motor is the dry closed asynchronous one, which makes sure that the motor can work smoothly in water.

Q:How do vacuum pumps and pumps work together?
Vacuum suction principle of self suction pump:Assuming that the pump connected with the water inlet of a sealed container, the container has plenty of water, since the start of a water pump, water is thrown out of the water impeller pump body, water inlet seal vessel due to the extraction of water to form a vacuum cavity, this assumption will be connected to vacuum cavity and exposed to atmospheric conditions of water, water at atmospheric pressure under the effect of entry into the vacuum chamber".
Q:Why should the pump be closed when the centrifugal pump is started?
On the other hand, the water on the pipe of the inlet pipe of the pump is stationary before the pump is opened, such as the sudden acceleration, and the water behind it can not keep up, which will cause the pressure of the inlet to drop suddenly and vaporize the water, and the centrifugal pump will be evacuated. (because of the centrifugal pump is rotating centrifugal force generated by the pump, leaf water and steam driven (gas) quality is very light, according to F= Ma, the centrifugal force is small, the pump can not be water sent).
Q:Must the water pump in the tank be all soaked in water?
Need a submersible pump in the water, but it is not entirely like this, I have to work for a long time no problem in water, but there is a problem you should pay attention to the water pump, at least in half, or stop when the smoke is not on water.
Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
The power of axial flow pump decreases with the increase of flow rate, and it is a steep curve, so the centrifugal pump starts with an open valve.
Q:What kind of motor does the hydraulic pump need?
The motor should be determined according to the work environment, such as 220V.12V.24V.72V or 380V, and then the power.Calculation of actual oil pump power:
Q:What is the difference between swashplate pump and crankshaft pump?
In hydraulic system:Axial piston pump is the use of parallel with the transmission shaft in the plunger plunger reciprocating movement of the volume changes generated by the work. As the plunger and the plunger hole are circular parts, processing can achieve high accuracy with the high volume efficiency, stable operation, good flow uniformity, low noise, high working pressure, but the hydraulic oil pollution is more sensitive, more complicated structure, high cost.
Q:Is the vacuum pump air compressor?
A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physical chemical method to pump a vacuum from a container to be evacuated. Generally speaking, a vacuum pump is a device that uses various methods to improve, produce, and maintain a vacuum in a confined space.
Q:Advantages and disadvantages of centrifugal pumps?
Centrifugal pump; advantages and disadvantages:(1) advantages:The structure of the pump is simple and compact, and the centrifugal pump has small area, light weight, little material consumption and high cost for the foundation. Therefore, the cost of manufacturing and installation is less.For high speed operation, the 2 pole or 4 pole motor can be directly connected. The drive structure is simple and easy to install.
Q:Difference between pump and compressor
Working principle:The impeller is installed in the pump casing and is fastened on the pump shaft 3, and the pump shaft is directly driven by the motor. There is a liquid suction in the center of the pump shell, and 4 is connected with the suction pipe 5. The liquid through the bottom valve 6 and the suction tube into the pump.The liquid discharge port 8 on the pump housing is connected with the discharge pipe 9. Before the pump starts, the pump shell is filled with the liquid to be transported; after starting, the impeller is driven by the shaft to rotate at high speed, and the liquid between the blades must also rotate. Under the influence of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and obtains energy, and leaves the outer edge of the impeller at high speed to enter the volute pump shell.
Q:What are the basic technical parameters of the pump?
Two, pump head H head is the unit weight of the liquid pump pumping from the inlet of the pump (pump inlet flange) to the outlet of the pump (pump outlet flange) energy value. Effective energy is a Newtonian liquid through the pump unit is obtained. The N m/N=m, the height of liquid column pumping liquid. Habits referred to as meters. Three, the pump speed is n RPM pump unit time revolutions, represented by the symbol n, the unit is r/min. four, the pump NPSH NPSH NPSH is also called net positive suction head, said main parameters of cavitation performance. Cavitation has been used a h power of five, the power of the pump. And the efficiency of the pump is usually refers to the input power, which is the prime mover on the pump shaft power, it is also known as the shaft power, denoted by P;
