1.Structure of Submersible Pump for Sewage Water Pump Station Description
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: Troubleshooting of diaphragm pump
- The ratio of flow to water weight at a specific weight of --68F. 68F water has a specific gravity of 1Static suction head - the vertical distance from the liquid level to the central line of the pump. The pump shall be above the level of the liquid.Vapor pressure the pressure of all the steam on the free surface of the liquid. In any pump operating system, the operating pressure shall not be lower than the vapor pressure, otherwise the steam will be partially or completely cut off into the pump fluid. Viscosity - because of the presence of friction in the fluid, the property of viscosity gives the fluid resistance to flow.Water hammer action -Water hammer is a sudden power failure, or in the valve closed too fast, due to pressure, flow of inertia, produce water shock waves, like hammer hammer, so called water hammer. The force produced by the flow of water shock waves can sometimes be very large, thereby damaging the valves and pumps. Water hammer effect refers to the inside of the water pipe, the pipe wall is smooth, flow freely. When the opening of the valve suddenly closes, the flow of water to the valve and the tube wall, mainly the valve, will produce a pressure. As the pipe wall is smooth, the subsequent water flow in the role of inertia, the fastest reach the maximum and damage, which is the water conservancy "water hammer effect", that is, "positive water hammer.". This factor should be taken into consideration in the construction of water conservancy pipelines. On the contrary, the valve closed in a sudden opening, it will produce water hammer, called negative water hammer, but also a certain destructive power, but not the former big.. Causes and treatment methods of common failures of diaphragm pumps:
- Q: How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?
- Water ring vacuum pump is divided into many types, different sizes, different types, so water is different. As for how much water the no fixed amount, but to ensure that the water temperature is in 25 degrees, not more than 35 degrees can be.
- Q: How to select metering pump head?
- When it comes to metering pump heads, the usual problem is when they measure acid, chlorine, fluoride, and hydrogen peroxide. Due to the difference in concentration and operating temperature, it is difficult to determine the specific pump head material.
- Q: How to install, operate and maintain the pipeline booster pump?
- The motor coil is provided with a safety protector, and when the pump is out of order or the water is not pumped, the motor can automatically break down when the temperature of the motor exceeds the prescribed value, and the motor can automatically resume operation after the temperature rise of the motor is decreased. The booster pump motor is a capacitor running type motor. When the pump leaves the factory, the rotation direction has been adjusted. If you need to replace the capacitor or re connect, press the arrow direction on the pump body to mark the connection. To ensure safety, use the three - core safety socket with ground wire.
- Q: What is the lift off the dead center point? This is a straight mark about the water pump. What is the function and the relationship between the design head and the pump head? ThanksWhat exactly is the dead point lift? What's the function of this indicator?
- In a dead head will be relatively high, the main downstream equipment and pump, if a dead head high, so the design pressure of the pump needs downstream equipment will be relatively large, resulting in the cost increases, so close a better head lower dead point.
- Q: I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?
- (8) check the suitability of the foundation and whether the size of the foundation corresponds to the size of the pump.(9) find the position of positive pump and motor, pump set and anchor bolt and the inlet and outlet flanges, to ensure that the flange torque of the pump conforms to the standard. Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition. It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.
- Q: What should be used to pay attention to the use of mechanical pumps?
- Overall: large pump should first do a good job of the foundation, to find a good whole, fixed, and motor, pump should be added good oil, the first test of the motor, and then conjoined test
- Q: Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
- The direct connected pump impeller is directly mounted on the motor shaft, and the non direct connected pump and motor are two shafts, and the two shafts transmit torque through the coupling
- Q: What are the problems that should be paid attention to when using vacuum pumps?
- (1) check the vacuum pump line and the joint site regularly to see if there is any looseness. Turn the vacuum pump by hand and see if the vacuum pump is flexible.(2) add lubricating oil to the bearing body, observe the oil level at the center line of the oil mark, and the lubricant shall be replaced or supplemented in time.(3) plug screw vacuum pump of the water screw, filling water (or lead paste). (4) turn off the gate valve of the water outlet pipe and the outlet pressure gauge and the vacuum gauge. (5) point motor, and see if motor steering is correct.(6) start the motor. When the vacuum pump is in normal operation, open the outlet pressure gauge and the inlet vacuum pump. As soon as the proper pressure is shown, the gate valve is gradually opened, and the motor load is checked.
- Q: Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why
- Reciprocating pump is a positive displacement pump, the volume change of flow is the unit of time, constant flow speed constant, can not rely on increased resistance to change the flow resistance increase is only leaked, only small changes in flow.
