How many kilowatts of a 200 mm pipeline with a 4000 meter transportation level need to be equipped w

The lift of the pump is mainly affected by the water storage height (head) and the friction in the water pipe (the longer the water pipe, the larger it is, but it can be basically ignored compared with the head), that is: the actual power of the pump is mainly affected by the height (head), the general rated power is the actual power under the height of 80% of the head, and the rated power is basically only about 10% when the head is 0 (horizontal) (electric energy is converted into kinetic energy);

2.The horizontal water storage head is greater than 10 meters, if it is a fixed water storage, 15 meters is the most suitable;

3.If it is used frequently (pipe diameter less than 6cm), in order to improve the rate and future use, it is recommended to use a head of 35 to 50 meters;

4.The higher the head, the greater the power and accuracy of the product, and the greater the water absorption height, which is cost-effective but practical;

Recommended: The horizontal water storage head is 15 meters. (The quality certification of the pit man, not professional at all, wasting my time).

1.In order to improve the rate and future use: the horizontal water storage head is 15 meters, if the waiting water storage, the head is 0 (horizontal) is basically only about 10% of the rated power (electric energy is converted into kinetic energy);

2.The head of the water pump is mainly affected by the water storage height (head) and the friction in the water pipe (the longer the water pipe, the larger it is, but it can be ignored compared with the head), that is: the actual power of the pump is mainly affected by the height (head), and the general rated power is the actual power at 80% of the head height, and 15 meters is the most suitable;

3.If it is used frequently (pipe diameter less than 6 cm), a head of 35 to 50 m is recommended. The higher the head, the greater the power and accuracy of the product, and the greater the water absorption height, which is cost-effective but practical;

A centrifugal pump is installed at the meter of the water well face, the pump flow rate is 20m h, the suction pipe is 108 4 steel pipe, and the energy loss in the suction pipe is. Find the pressure at the inlet of the pump. The local atmospheric pressure is 100kn and the water is 1000 m.

If it is a water supply pipeline, the allowable flow rate of DN20 is 0 5 1 5 (m s); The converted flow rate is: 0 6 1 7 t hours.

Relationship between flow and pressure in a pipe:

Flow velocity, flow rate, and pressure in a pipe.

Flow rate: V=C(rJ)=C[PR(GL)].

Flow rate: Q = CA (RJ) = [P ( GSL)].

where: the coefficient of the c pipe; l Pipe length; p Pressure difference between the two ends of the pipe; r Hydraulic radius of the pipeline; liquid density; g Acceleration due to gravity; s Friction of pipes.

Mechanical seal flushing water selection.

There is a pressure difference between the water in the pump and the atmosphere outside the pump, and the function of the mechanical seal is to prevent the liquid from leaking out when the pressure inside the pump is greater than the atmospheric pressure, and when the pressure inside the pump is less than the atmospheric pressure, it prevents the air from leaking into the pump. Due to the characteristics of the water quality in the swirl well, it is necessary to install an external clean machine seal to flush the water, on the one hand, to protect the machine seal, and on the other hand, to maintain the vacuum. Because the pressure of the sealing chamber of the double suction pump is negative pressure, the water pressure of the machine seal is not lower than that.

Thank you for your additional questions to be comprehensive and easy to answer.

Summary. Dear, The head of the pump is mainly affected by the water storage height (head) and the friction in the water pipe (the longer the water pipe, the larger it is, but it can be basically ignored compared with the head), that is: the actual power of the pump is mainly affected by the height (head), the general rated power is the actual power at 80% of the head height, and the rated power is basically only about 10% (electric energy converted into kinetic energy) when the head is 0 (horizontal).

Horizontal conveying distance of 100m, how many head pumps to choose.

For kissing, Yang Cheng needs about 150, and at least 125 or more.

Dear, The head of the pump is mainly affected by the water storage height (head) and the friction in the water pipe (the longer the water pipe, the larger it is, but it can be basically ignored compared with the head), that is: the actual power of the pump is mainly affected by the height (head), the general rated power is the actual power at 80% of the head height, and the rated power is basically only about 10% (electric energy converted into kinetic energy) when the head is 0 (horizontal).

So, dear, at 80 percent, 100 80% get the answer is 125 meters.

Dear, therefore, it is recommended to be around 150 meters to Yang Cheng. It should be at least 125 meters or more!

Summary. According to the actual flow rate, first estimate a pipe diameter Check the pipeline hydraulic calculation table, and get the specific friction resistance, the unit is pa per meter. Multiply the length to get the resistance along the way, and multiply it by the local resistance along the way (according to the number of elbow valve fittings, more than 200 meters will be selected to add up to the resistance of the pipeline.

For example, the diameter of the pipe is DN40, the flow rate of mS, and the resistance of about 1200pa m. Therefore, 1000*1100pa m=

Local Assist Calculation:

Vertical height 100m: 100 10 = 10 bar = 1mpa

So the outlet pressure

Coupled with the margin and the pressure of the guaranteed outlet, the head should be selected above.

Note: The pipe diameter and flow rate in this calculation are approximate estimates, and the actual pipe diameter and flow rate should be checked in the table, and the data may be very different for different pipe diameters and flow rates.

The vertical height is 100 meters, and the horizontal conveying is 1000 meters, and the head pump must be large.

Dear, hello, please wait a moment, we have seen your question in Bishan, and we are sorting out the information for you quickly, and we will send your answer to the little master immediately. Thank you for your support, recognize my service, and remember to give a thumbs up<>

According to the actual flow rate, first estimate a pipe diameter Check the pipeline hydraulic calculation table, and get the specific friction resistance, the unit is pa per meter. Multiply by the length to get the resistance along the way, and multiply it by the local resistance along the way (according to how much the elbow valve pipe fittings are selected, more than 200 meters will be selected to add up to the resistance of the pipeline. Such as the comic stove Bi:

The diameter of the pipe is DN40, the flow rate is about 1200pa m. Therefore, 1000*1100pa m = local power assist calculation: vertical height 100m:

100 10 = 10 bar = 1mpa so the outlet pressure plus the margin and the pressure to ensure the outlet, the head should be selected above. Note: The pipe diameter and flow rate in this calculation are roughly estimated, and the actual pipe diameter and flow rate should be checked in the table.

How many kilowatts is the seat pump motor and what model of the pump is.

The selection of the water pump motor should be selected according to the shaft power; The motor power is one level greater than the power of the pin-to-spine shaft; For example, if the shaft power is 15kw, the motor should be selected as follows: As for the use of Huaipai several pole motors, it should be based on the actual working conditions.

Is there a model number of water pump**? Send it to see.

S150-125-250, IS refers to single-stage single-suction clean water centrifugal pump, 150 refers to wide reed attack suction inlet diameter (mm).125 refers to the direct discharge port (mm) and the diameter of the impeller (mm).

300 cubic meters of water output, 500 meters of head, 2500 meters of cavity length, 200 pipes of the first Huai shirt diameter, need to use a multi-stage pump D280-60*10, motor 900 kilowatt 4-stage, speed 1450 rpm, pump inlet and outlet are 200 mm diameter.

The customer's requirement is a submersible pump.

The pipe diameter is 63, assuming the flow rate of 2, the flow rate is about 22 cubic meters per hour. The height is 12 meters, and the design head is 25 meters. The effective power of Germany is 25 * 22 * 1000 * 10 equal to the size of the kilowatt hall ridge.

Considering the efficiency, a 5 kW motor is sufficient.

Are you still there? Hmmm.

The customer requires a submersible sewage pump, please ask how many meters of head to choose.

PVC pipe is used, the pipe diameter is calculated according to the economic flow rate, and the outer diameter of the pipe is 160mm; At this time, the pipeline is lost along the way; The minimum head of the pump is 40+. Considering the pipe joints, elbows, etc., the minimum lift of the pump is 50m.

If you choose a 250mm hot melt pipe, then how many meters of head submersible pump is needed.

I don't know very well, I'm sorry.

You give me a suggestion.

I'm afraid that I will make a mistake, and I can't give this advice, after all, it's very important, I'm sorry.

What you mean is that if you use PVC160 pipes, you should use a minimum head of 50 meters. Well.

Dear, hello, Zaozheng is happy to answer this question for you When the water pump is used to transport 10,000 meters, the suction flow and pressure of the water pump must meet the following requirements: the water flow rate should not be less than 300 cubic meters per hour, and the water pressure should not be less than 3 meters. If the power of the pump used to transport the wastewater for 10,000 meters is all used to generate pressure, the power required should be no less than 9 kW per hour, and they may have the following options:

1) Straight flow pump: It has a power requirement of 10-15 kilowatts, which has a relatively high efficiency. (2) Mixed water pump:

Its power requirements are between 15-20 kW with a certain efficiency. (3) Screw pump: its power requirement is between 20-30 thousand picowatts, with high efficiency.

4) Electromagnetic speed control pump: its power requirement is between 30-50 kilowatts, with relatively high efficiency. (5) Others:

Since different types of pumps have different power requirements, there are a number of other types of pumps to choose from. In addition, the quality of the pipeline used to transport 10,000 meters is also important. In general, pipes that meet national standards should be used, and the outer diameter of the pipeline should not be less than DN300, and the outer wall of the pipeline should be hard and dense to ensure normal operation.
