The pump on the water but can only hit 20 meters 15

See if the impeller is blocked, or maybe the pipe.

Reason 1. There is a foreign object blocking the pipe.

Reason two. There is an air leak in the suction pipe. (Because the two pumps share a suction pipe, it may also leak from another pump, so it is recommended to use their own suction pipes).

The third reason is that the impeller speed is not enough (lost rotation).

Check the three-phase voltage during operation and comprehensively analyze the three-phase current and water output.

The situation should be clear, how the two pumps are used, series and parallel; Pump arrangement, suction, backfilling? The layout of the pipeline, the elevation is 28 meters, the pipeline is about 28 meters long, straight up and down, what is the diameter of the pipe? How do you call it the first time, and then it only hits 20 meters, is there an opening in the middle of the pipeline?

There is still a pressure gauge to display.

A single pump runs, suction type, there is no opening in the middle of the pipeline, and there is no water after the water is sprayed out after starting, which is equivalent to only hitting 20 meters of water column.

If the pump is too large and cavitation occurs, there will be water flowing out in the future, sometimes large and sometimes small; The pump is small, the head can overcome the elevation but is not enough to overcome the loss of another pipeline, 37-28 = 9 meters, set up the suction meter, then there is a meter pipeline loss, the pipe length is more than 28, the pipe diameter is set to 100mm, the flow rate is 100 square meters, the loss is about 3 meters, according to the actual working conditions substituted into the formula calculation. There is also a possibility that there is no air leakage in the inlet pipeline, the inlet valve is fully open, and there is no hose.

The outer diameter of the impeller inlet and the mouth ring clearance of the pump casing should not exceed 1 mm. There is also an impeller that needs to be adjusted if it is open. The clearance should also not be higher than 1 mm.

1. There is only one condition for water delivery of 200 meters, and it is impossible to determine how much water pump is needed. To choose the right pump, you need to add additional conditions: flow rate and head.

2. Assuming that 200m is the horizontal distance of water supply, the actual length of the pipeline is 210m, and there are only a few elbows in the pipeline, the water is 50m h, and the pipe diameter is DN100. Now it's time to calculate.

Resistance along the way: 14m calculated by hydraulic software.

The head of the pump is: resistance loss along the way + affluence coefficient. 14 + 5 = 19m3, select the pump:

Optional IS100-65-250 water pump, flow: 50m h, head: 20m, motor power.

To determine the size of the pump, two points should be determined: 1. What is the flow rate you need? (How many tons of water per hour) 2. Determine whether 200 meters is the pump distance or vertical distance (if it is a vertical distance, it is the head of the pump, if it is a horizontal distance of 200 meters, calculate the pipeline resistance according to your pipeline, and calculate the pump head according to the height you hit).

The water selection pump generally determines these two points: flow and head. Pumps with specific power are selected according to the flow rate and head.

For example, the flow rate: 1 ton hour, the head: 200 meters, 3kw can be.

If the flow rate: 6 tons per hour, head: 200 meters, you need a pump.

It depends on what medium you're pumping and how much flow you want.

Summary. Hello, 1, there is only a condition of 200 meters of water, and it is impossible to determine how big the pump is needed. To choose the right pump, you need to add additional conditions: flow rate and head.

It is necessary to deliver water for 200 meters, and how big a pump is needed.

Hello, 1, there is only a condition of 200 meters of water, and it is impossible to determine how big the pump is needed. To choose a suitable water god pump, you need to supplement the conditions: flow rate and collapse head.

2. Assuming that 200m is the horizontal distance of water supply, the actual length of the pipeline is 210m, and there are only a few elbows in the pipeline, the water is 50m h, and the pipe diameter is DN100. Now it's time to calculate the repentance. Resistance along the way:

The head calculated by the hydraulic software is that the pump is directed: resistance loss along the way + Fuqi staring coefficient. 14+5=19m

3. Choose Mizuno pump: optional IS100-65-250 wheel bright water pump, flow ridge width: 50m h, head: 20m, motor power.

Summary. Dear, hello, the pump head of 20 meters The vertical of the pump can hit 20 meters high, and the head of the pump is to point out the vertical distance between the water nozzle and the suction surface. The head of the water pump is divided into suction head and pressurized water head, taking centrifugal water pump as an example, its suction head will not exceed ten meters, and it uses atmospheric pressure to work, and atmospheric pressure can only support a water column about ten meters high.

The pressurized head is the height of the impeller shaft and the water outlet.

Dear, hello, the pump head of 20 meters The vertical of the pump can hit 20 meters high, and the head of the pump is to point out the vertical distance between the water nozzle and the suction surface. The head of the water pump is divided into suction head and pressurized water head, and the centrifugal water pump is taken as an example, its suction head will not exceed 10 meters, and it uses the air pressure of Dachamu to work, and the atmospheric pressure can only support the water column about 10 meters high. The pressurized water lift is the height of the impeller axis and the water outlet.

I pump water in the river, and then I take 600 meters to go up to 10 meters high, and 20 meters long is enough?

Pro, the pipeline is 600 meters long, and it is estimated that the head of the pump is 80 meters.

Kiss, the pump head required to be ten meters high should reach about 23 meters, because the pump head is divided into two parts, the first pumping part is also considered a head, the head of the pumping hall is about 8 meters, 10 meters high building, in addition to the loss of the pipeline, but also to maintain a certain water pressure, his Yang Congheng first journey must reach about 15 meters, the number of seepage so these two can be added to get that the head of the pump must reach 23 meters to meet the requirements of water supply!

Summary. Extended information: There is only one condition for 200 meters of water, and it is not possible to determine how much pump is needed.

To choose the right pump, you need to add additional conditions: flow rate and head. Assuming that 200m is the horizontal distance of water supply, the actual length of the pipeline is 210m, the pipeline has only a few elbows, the water is 50m h, and the pipe diameter is DN100.

Summary. Hello, to determine the size of a water pump, there are several factors that need to be taken into account: water flow, head, and diameter of the water pipe.

In this problem, we already know the elevation and the height of the water pipe, so we only need to calculate the required water flow and the diameter of the water pipe to determine the required pump size. 1. The required water flow needs to be determined. This can be determined by estimating the number of people using the water, what the water will be used for, and how long it will be used.

Assuming 1,000 litres of water per hour are required, then the flow rate of the pump should be at least 1,000 litre-hours. 2. The diameter of the water pipe needs to be considered. The larger the diameter of the pipe, the more power the pump requires.

In general, the power of the water pump should be determined according to the diameter of the water pipe. In this question, assuming that the diameter of the water pipe is 50 mm, then the power of the water pump should be in kilowatts. <>

Kiss, <>

<> a pump with a level of 20 meters and an elevation of 15 meters.

A total of 35 meters. Hello, to determine the size of a water pump, there are several factors that need to be taken into account: water flow, head, and diameter of the water pipe.

In this problem, we already know the elevation of the source and the height of the pipe, so we only need to calculate the required water flow and the diameter of the pipe to determine the required pump size. 1. The required water flow needs to be determined. This can be determined by estimating the number of people using the water, what the water will be used for, and how long it will be used.

In general, the power of the pump should be determined according to the diameter of the water pipe. In this question, assuming that the diameter of the water pipe is 50 mm, then the power of the water pump should be in kilowatts. <>

Kiss, <>

<> can choose a Lingzhili water pump with a flow rate of 1000 liters per hour and a power of kilowatts. It should be noted that this is only an estimate, and the actual situation needs to be adjusted according to the specific situation. Hello! Hope mine can help you. <>

Dear, I am glad to answer for you: you need to determine the lower flow rate to determine the pump model, but this head of 500 meters must choose a horizontal multistage lead key pump. The horizontal distance can be 10 meters equal to 1 meter head, 200 meters is equal to 20 meters plus the height difference of 30 meters plus 5 meters of elbow, the pump head can float up and down 10, should be selected about 60 meters can be 10 tons of hours, the distance is 500 meters, choose DN65, PE pipe, the average flow rate is meters per second, and the hydraulic loss is 7 meters.

The bureau shouted that the head was 129 meters. DN50 and PE pipes are selected, the average flow rate is meters per second, and the hydraulic loss is 28 meters. Therefore, the head is 150 meters.

Summary. In this case, the head is wasted on the loss of pipeline resistance, and when the water is sent to the top of the equipment, the water pressure will be relatively large, that is, the water may come out like a fountain.

Your stupid lead head is wasted on the loss of pipeline resistance, and when the water is brought to the top of the equipment, the water pressure will be relatively large, that is, the water may be a fountain.

So the actual output distance of his current output is not enough.

There's no way to change that.

Unless used on a flat ground above a horizontal plane.

Of course, you can also stick to whether your voltage is enough.

It is also necessary to ensure that the machine is running at full power.

I hope I can help you, I wish you a happy life, and I hope to give a thumbs up. <>Then do you have to change the deep water pump?

That's right. Change to a more powerful one.

Also make sure that your current voltage is normal.

Ensure that the machine runs at full power to achieve the desired effect.
