5. RFQ
1> What's the difference for CHL and CHLF(T) type?
CHL pumps have an inlet and outlet chamber which is made by stainless steel. CHLF(T) is just the section type.
2> Do you have any variable motor for these pumps?
Yes, we have. For the variable motor, the frequence can be changed as the customers' request. If the range is between 30~50Hz, the fan can be just connected with the shaft. And if the frequency is below 30Hz, then the fan has to have another separated power. The variable speed motor would be used for solar energy or some other similar situation with the unstable power.
3> How about the Delivery time?
Actually, this would be depending on the quantity. If it is just small order, 1 week would be fine. For bigger quantity, the delivery would be also less then 20 days. But for the varible speed ones, it will be taking some more time, normally it will be more than a month.
- Q: Why does the centrifugal pump close the pressure to start?
- Therefore, the operation rules of multistage centrifugal pumps require that the inlet valve be opened before opening, and the outlet valve is closed. However, the export valve closed time can not be too long, because at this time the medium in the pump cycle, the medium temperature gradually increased, easy to cause mechanical seals, due to lack of lubrication friction and wear or damage.
- Q: Must the water pump in the tank be all soaked in water?
- Usually you have to soak it all in the water. If you don't want to put it in the water, you can buy an amphibious pump. At most, you can expose it
- Q: What should I pay attention to when buying a pump?
- Two, the first choice of large and medium-sized professional manufacturers, and through the quality identification of relevant departments, the market credibility of the better models, but also to the professional quality inspection institutions consultation.Three, check the motor grounding device for electric pump, water pump and motor axis, the motor should be in a proper position is provided with a grounding screw, and the grounding screw are arranged near the ground; grounding device of small submersible pump should be reliable and grounding wire, grounding wire cables should have the obvious grounding mark the flag should be in use; the motor is not easy to be worn during the period. This is one of the important safety indexes of electric pumps.
- Q: What are the application areas of pumps?
- 1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system
- Q: What are the characteristics of a vertical multistage centrifugal pump?
- Vertical multistage centrifugal pump system using the latest international advanced IS type hydraulic model based design for high efficiency centrifugal pump with multi segment, the soft packing or mechanical seal, has the characteristics of high efficiency, large flow, high lift, no leakage, a wide range of performance, safe operation, stable operation and long service life and small area.
- Q: Is the centrifugal pump large or small?
- Centrifugal pump, the smaller the better the cavitation.1, centrifugal pump cavitation less, anti cavitation performance is better, the pump cavitation is called the necessary cavitation margin or pump inlet dynamic pressure drop, the smaller the better. Generally speaking, the pump cavitation is the need for cavitation, the pump inlet pipe said effective cavitation margin, that is, the device cavitation margin. For a given pump, at a given speed and flow rate required NPSH is called pump necessary NPSH, also called NPSH, is required to achieve the performance parameters of the pump cavitation, the internal flow and the centrifugal pump is composed of pump head itself, its physical meaning is that liquid drop in pump inlet pressure part degree, is to guarantee the pump cavitation does not occur, with surplus energy exceeds the vaporization pressure head at the inlet of the pump unit weight of liquid. The cavitation must be independent of the device parameters. It is only related to the parameters of the inlet of the pump. These parameters are determined by the geometric parameters at a given speed and flow.
- Q: Is the flow meter in front of the pump or after the pump?
- After the flowmeter is placed in the pump, it is better to add a pressure tank or a buffer tank, so that the flow meter will work better
- Q: How to maintain and repair the booster pump of pipeline pump?
- Installation and use1. use rubber washer and bolt to connect the pump flange at both ends and the pipe flange. In order to use and maintenance convenience, in the pump inlet and outlet pipelines should be installed with a regulating valve.2. open the inlet control valve, so that water into the pump, in order to keep the cavity filled with liquid (otherwise it will damage the seal), close the outlet valve.3. turn on the power and make sure the correct turn.4. make sure the pump starts and runs after turning.5. adjust the opening of the outlet valve so that the pump runs near the design point, depending on the rated flow and lift of the pump. [for this reason, it is better to place a pressure gauge near the outlet flange). Note: this pump is strictly prohibited to run without water, so as not to damage the seal.
- Q: What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?
- A single-stage pump is a pump with only one impeller. 2, a multistage pump is a pump with two or more impellers. The multistage pump can increase the pressure and lift the head higher. Level 1 means a booster impeller.
- Q: What is the difference between centrifugal pump and self suction pump? Which is better?
- If the centrifugal pump in full before the start of the shell of the gas, then start after the center of the impeller was thrown in the gas can not be large enough to form the vacuum, so that liquid in the bath can not be sucked, so the centrifugal pump to start before using foreign liquid in the pump housing space filling
