Generally speaking, the weight of a 900 kilowatt centrifugal water pump is at least a few tons, and it may reach the range of 3-10 tons. However, the specific weight still needs to be calculated according to the size, material, and after-fibrillation structure of the specific product.

Approximate how much does it cost?

The specific quality of the 900 kilowatt centrifugal water pump depends on the brand, model, material, use and other factors. In most cases, the failure of centrifugal pumps will range from tens of thousands to hundreds of thousands of yuan.

The flow rate of mining multistage centrifugal pumps drops after a long period of operation, which may be caused by a variety of reasons. Here are some possible causes and workarounds:

Changes in the nature of the conveying medium: During the operation of the mining multistage centrifugal pump, the change in the nature of the conveying medium, such as an increase in viscosity or an increase in the content of solid particles, may lead to a decrease in the flow rate of the pump. Workaround:

Check the nature of the conveying medium, if there is any change, the working parameters of the pump should be adjusted or a suitable pump should be replaced.

Pump inlet blockage: The inlet of the pump may be clogged due to debris, sediment, etc., resulting in a decrease in the flow rate. Solution: Check and remove the blockage at the inlet.

Increased system resistance: Blockages, leaks, incomplete valve closures, and other problems may occur in the piping system where the pump is located, resulting in increased system resistance and thus reduced pump flow. Solution: Check the entire system to troubleshoot and resolve the resistance problem.

Worn Pump Bearings: After long periods of operation, the bearings of the pump may wear out, resulting in a decrease in the efficiency of the pump and therefore a decrease in flow. Solution: Inspect and replace worn bearings.

Impeller wear: The impeller of a pump may wear or damage after a long period of operation, resulting in a decrease in the flow rate of the pump. Solution: Check and replace the impeller.

Mechanical seal wear: The pump's mechanical seal may wear out after prolonged operation, resulting in a decrease in the pump's flow rate. Solution: Check and replace the mechanical seal that has been worn out.

Insufficient motor power: The pump's drive motor may have insufficient power due to voltage instability or motor problems, thus reducing the flow rate of the pump. Solution: Check the motor and power supply to solve the problem of insufficient power.

To sum up, there may be many reasons for the flow rate drop of mining multistage centrifugal pumps, which need to be investigated and dealt with according to the actual situation. It is recommended that the pump be maintained and inspected regularly to ensure its stable operation.

The reasons for the halving of the flow rate of the mining multistage pump are as follows:

1. The suction valve is blocked; Carry dates.

2. The resistance of the suction pipeline is too large or the water absorption height is too high;

3. The resistance of the outlet pipeline is too large;

4. There is air in the suction tube of the centrifugal pump and there is air leakage;

5. The impeller is blocked;

6. The sealing ring is seriously worn and the gap is too large;

7. The motor rotates in the wrong direction.

The treatment method of reducing the flow rate of the mine multistage pump by half is as follows:

1. Clean the suction valve;

2. Clean the pipeline of absorbing and destroying hidden people or reduce the height of water absorption;

3. Inspect and clean the outlet pipeline or improve the inlet and outlet pipes;

4. Remove air and eliminate air leakage;

5. cleaning the impeller;

6. Replace the impeller sealing ring;

7. Adjust the direction of rotation of the motor. Elimination.

The reasons for the drop in traffic are as follows:

1. The suction valve is blocked;

2) The resistance of the suction pipeline is too high, or the water absorption height is too high.

3) The resistance of the outlet pipeline is too great.

4. There is air in the suction tube of the centrifugal pump and there is air leakage;

5. The impeller is blocked;

6. The sealing ring is seriously worn and the gap is too large;

7. The motor rotates in the wrong direction.

Summary. The centrifugal pump head you choose is too high, and it is difficult for the centrifugal pump to achieve a head of 6000 meters. According to your description, the head of the pump should be selected as the slope height + pressure loss of the pipe network, about 35-40 meters of head is enough.

The motor power is about 15-22kw. This is experience points, no standards or formulas have been queried, I hope it can help you.

The centrifugal pump lifts water 100 meters high and 6,000 meters long, depending on the power of the centrifugal pump.

The centrifugal pump head you choose is too high, and it is difficult for the centrifugal pump to achieve a head of 6000 meters. According to your description, the head of the pump should be selected as the slope height + pressure loss of the pipe network, which is about 35-40 meters of head. The motor has about 15-22kw of power chain.

This is the experience value of the key empty sun.,I haven't consulted the standard or formula calculation.,I hope it can help you.。

May I ask you whether your 6000 meters is vertical height or horizontal length, if it is vertical height, then the ordinary centrifugal pump is not up to the 6000 meters of head, to use a multi-stage centrifugal pump, if it is a horizontal length, the general use of the pump is already able to meet your requirements, depending on which manufacturer produces the pump head flow is not the same draft, this requires you to provide more parameters to help you choose! Yongke Electromechanical will give you a respectful answer, hope.

To calculate the weight of a centrifugal pump, the following factors need to be considered:

The head of the centrifugal pump (head): The head of the centrifugal pump refers to the pressure required to overcome the resistance of the water flow when pumping water, which is generally expressed in meters (m). The higher the head, the greater the weight of the pump.

Density of water: The density of water refers to the mass of water per unit volume, which is generally expressed in kilograms per cubic meter (kg m3). The higher the density, the greater the weight of the pump.

Efficiency of centrifugal pump: The efficiency of centrifugal pump refers to the ratio of output power to input power of the pump. The higher the efficiency, the less heavy the pump will be.

Based on the above factors, the following formula can be used to calculate the multiplicity of a centrifugal pump:

Multiplicity = Head, Flow, Density) Efficiency

where the head unit is the meter, the flow unit is cubic meters per hour (m3 h), the density unit is kilograms per cubic meter (kg m3), and the efficiency is the percentage, which is an approximation of the gravitational acceleration in meters per square second (m s2).

For example, consider a centrifugal pump with a head of 20 meters, a flow rate of 500 cubic meters per hour, a water density of 1,000 kilograms per cubic meter, and an efficiency of 80%. Then the multiplicity of the pump is:

Multiplicity = 20m 500m3 h 1000kg m3) 80% 1272 kg.

Centrifugal pumps with a flow rate of 500 m3 h are available in a variety of sizes, depending on the required head and the required pressure. If the required head is low, a smaller caliber centrifugal pump can be used; Conversely, if the required head is higher than that of the crack, a larger diameter centrifugal pump can be used. In addition, if the required pressure is high, a multistage centrifugal pump can be used for the limb.

To calculate the power of a 550 lib centrifugal pump, you need to know the following parameters:

1.Flow rate Q: 550 cubic h

2.Head h: 50 meters is assumed (this refers to the height difference that needs to be overcome from the inlet to the outlet of the wild section of the water).

3.Efficiency: Hypothetical is the efficiency of a centrifugal pump).

According to the formula p = q h g where p denotes power, denotes liquid density, and g denotes acceleration due to gravity.

With water as a liquid, its density is about 1000 kilograms of cubic meters. Substituting the above parameters yields:

p = 550 x 50 x 1000 x 3600 x 48 kW.

Therefore, the power of this centrifugal pump is about 48 kilowatts. It should be noted that other factors should be considered in the actual use process to affect the performance and security stability of the whole system.

To calculate the power of a centrifugal pump at 550 cubic hours (litres per small chop), many factors need to be considered, such as how the pump works, the head, the efficiency, and so on. These factors all affect the calculation of power. The common formula is:

Power = Flow Head Efficiency Density, where the flow unit should match the indenter unit, usually meter per hour (m h). According to this formula, if we assume that the efficiency and density of the hail water are both 100 and 1 kilogram cubic meters, then the power of the 550 cubic hour centrifugal pump should be between 1 and 1 kilowatt, and the specific value needs to be calculated according to the actual situation. It should be noted that this formula is only suitable for the ideal situation of this sail, and the actual situation and whether the parameters are accurate should be considered in practical work.
