Do you know the price of pipeline centrifugal pump? What is the difference between a pipeline circul

The working principle of the pipeline centrifugal pump is that the centrifugal pump can send water out due to the action of centrifugal force. (Xi'an South pump is easy to use) water pump before work, the pump body and water inlet pipe must be filled with water to form a vacuum state, when the impeller rotates rapidly, the blades promote the water to rotate quickly, the rotating water flies away from the impeller under the action of centrifugal force, the water in the pump is thrown out, the central part of the impeller forms a vacuum area.

The water in Suwon is pressed through the pipe network into the inlet pipe under the action of atmospheric pressure (or water pressure). In this way, continuous pumping is possible. It is worth mentioning here that:

Before starting the centrifugal pump, it must be filled with water in the pump casing before it can be started, otherwise it will cause the pump body to heat up, vibrate, reduce the water output, and cause damage to the pump (referred to as "cavitation") and cause equipment accidents!

The pipeline circulating pump is usually an ordinary vertical or horizontal single-stage centrifugal pump.

The centrifugal pump uses the rotation of the impeller to make the water centrifugal move to work. Before the pump starts, the pump casing and suction pipe must be filled with water, and then the motor is started to make the pump shaft drive the impeller and water to do high-speed rotation movement, and the water undergoes centrifugal movement, which is thrown to the outer edge of the impeller and flows into the pressurized water pipeline of the pump through the flow channel of the snail pump casing.

The basic structure of the centrifugal pump is composed of eight parts, namely: impeller, pump body, pump cover, water retaining ring, pump shaft, bearing, sealing ring, stuffing box, and axial force balance device.

1. The impeller is the core part of the centrifugal pump, which has high speed and large output force.

2. The pump body is also called the pump casing, which is the main body of the pump. It plays the role of support and fixation, and is connected with the bracket on which the bearing is mounted.

3. The function of the pump shaft is to connect the coupling with the motor to transmit the torque of the motor to the impeller, so it is the main component to transmit mechanical energy.

4. The sealing ring is also known as the leakage reduction ring.

5. The stuffing box is mainly made of packing, which does not let the water flow in the pump to the outside and does not let the outside air enter the pump. Always keep the vacuum inside the pump! When the pump shaft rubs against the packing to generate heat, it is necessary to fill the water seal pipe into the water seal ring to cool the packing!

6. Axial force balance device, in the process of centrifugal pump operation, because the liquid enters the impeller under low pressure and flows out under high pressure, the pressure on both sides of the impeller is unequal, and the axial thrust pointing to the inlet direction is generated, which will cause the rotor to rotate axially, produce wear and vibration, so the axial thrust bearing should be set up in order to balance the axial force.

There are several aspects to consider when choosing a pipeline centrifugal pump:

Flow requirements: Select the appropriate pipeline centrifugal pump according to the flow rate of the liquid to be delivered. In general, the higher the flow rate, the corresponding increase in the head and power of the selected pump.

Head requirements: select the appropriate pipeline centrifugal pump according to the head required to transport the liquid. Head refers to the total pressure that a liquid needs to overcome from inlet to outlet, and is generally used in meters or pascals. The head of the selected pump should be at or equal to the head required to convey the liquid.

Temperature requirements: Choose the appropriate pipeline centrifugal pump according to the temperature requirements of the liquid being transported. In general, centrifugal pumps are suitable for conveying liquids up to a temperature of 80 °C. If the temperature of the liquid is more than 80 °C, a high-temperature centrifugal pump needs to be selected.

Fluid properties: Choose the right pipeline centrifugal pump according to the nature of the liquid being transported. Different liquid properties will have an impact on the choice of pump, such as viscosity, corrosiveness, etc. It is necessary to select the appropriate pump material and sealing form according to the nature of the liquid.

Pump reliability and efficiency: When choosing a pipeline centrifugal pump, in addition to meeting the basic requirements such as flow, head, temperature, fluid properties, etc., the reliability and efficiency of the pump also need to be considered. In general, the more reliable and efficient the pump, the longer the service life and the lower the energy consumption.

Maintenance and service requirements: When choosing a pipeline centrifugal pump, you also need to consider the maintenance and maintenance requirements of the pump. In general, the simpler and more convenient the pump with maintenance and maintenance requirements, the lower the cost of use.

Based on the above aspects, the selection of a suitable pipeline centrifugal retainer pump requires sufficient technical comparison and evaluation. It is recommended to consult with a professional pump manufacturer or technician before choosing to ensure that the selected pipeline centrifugal pump can meet the actual needs.

Select the basic data of the pipeline centrifugal pump listed:

1. Characteristics of the medium: medium name, specific gravity, viscosity, corrosiveness, toxicity, etc.

2. The diameter and content of the solid particles contained in the medium.

3. Medium temperature: (

4. The required flow rate The leakage in the pipeline system can be ignored in the process of general industrial pumps, but the impact on the flow rate must be considered when the process changes. If the agricultural pump is used to transport water in the open file such as a local canal, the leakage and evaporation must also be considered.

5. Pressure: suction pool pressure, drainage pool pressure, pressure drop (head loss) in the pipeline system.

6. Pipeline system data (pipe diameter, length, type and number of pipeline accessories, geometric elevation from suction tank to pressurized water tank, etc.).

If necessary, a characteristic curve of the device should also be made. When designing the pipeline centrifugal pump to arrange the pipeline, the following matters should be noted:

1. Reasonable selection of pipe diameter, large pipe diameter, under the same flow rate, small liquid flow velocity, small resistance to rubber denier force loss, but high quality, small pipe diameter, will lead to a sharp increase in resistance loss, so that the head of the selected pump increases, the power of the belt increases, and the cost and operation concession costs are increased. Therefore, it should be considered from a comprehensive technical and economic point of view.

2. The discharge pipe and its pipe joint should consider the maximum pressure that can be withstanded.

3. The pipeline layout should be arranged as a straight pipe as much as possible, try to reduce the accessories in the pipeline and minimize the length of the pipeline, when it must be turned, the bending radius of the elbow should be 3 5 times the diameter of the pipe, and the angle should be greater than 90 as much as possible.

4. The discharge side of the pump must be equipped with valves (ball valves or globe valves, etc.) and check valves. The valve is used to adjust the operating point of the pump, and the check valve prevents the pump from reversing when the liquid is flowing backwards and protects the pump from water hammer. (When the liquid flows backwards, a huge reverse pressure is generated, which damages the pump).

Select the pipeline centrifugal pump to determine the flow head, the determination of the flow rate:

1. If the minimum, normal and maximum flow rate has been given in the production process, it should be considered according to the maximum flow rate.

2. If only the normal flow rate is given in the production process, a certain margin should be considered. For NS>100 high-flow low-head pumps, the flow margin is 5%, for NS<50 small-flow high-head pumps, the flow margin is 10%, for 50 NS100 pumps, the flow margin is also 5%, and for the pumps with poor quality and poor operating conditions, the flow margin should be 10%.

3. If the basic data is only given by weight, it should be converted into volumetric flow.

Pipeline centrifugal pumps

1.Piping arrangement.

The pipeline layout conditions of the device system refer to the conveying height, conveying distance and conveying direction of the liquid; The minimum liquid level on the suction side and the maximum liquid on the discharge side are the specifications, lengths, materials and quantities of these pipes, which are conducive to the calculation of the system head and the calibration of the NPSH.

2.The amount of liquid to be transferred.

One of the most important performance data for choosing a chemical pipeline pump is the liquid transfer capacity of the pump, which is directly related to the production capacity and conveying capacity of the entire equipment. When selecting a pump, the maximum flow rate is used as the basis, and the normal flow rate is considered, when there is no maximum flow rate, the slag book can generally be taken as a multiple of the normal flow rate.

3.Liquid properties.

Liquid properties refer to the name, physical properties, chemical properties, and other properties of the liquid medium. The physical properties mainly refer to the diameter of solid particles in the medium and the content of gas, which are related to the calculation of the head and effective NPSH of the system. Chemical properties mainly refer to the chemical corrosivity and toxicity of liquid media, which is an important basis for the selection of pump materials and the type of shaft seal for free dust.

4.Operating conditions.

When choosing a pump, consider whether the operation is interstitial or continuous, and whether the position of the pump is fixed or removable.

5.Device head.

The head required for the equipment system is another important performance data when selecting a pump. Usually, the head is selected after expanding the margin of 5 -10 .

1. The requirement of the impulse of the flow lead celery is to see how much water the user needs to extract, and the single suction pump, double suction pump, or small flow centrifugal pump can be selected in the requirements for the flow rate.

2. The head refers to the height of the pump that can lift water, which is an important working performance parameter of the pump. Users can choose single-stage pumps, multi-stage pumps, or high-speed centrifugal pumps for the height of the head.

3. In terms of the use environment, you can choose according to the site you need to use, including centrifugal pumps for chemical industry, high-temperature centrifugal pumps in high-temperature environments, and so on.

4. In terms of medium selection, users can choose according to the characteristics of the medium to be pumped according to their needs, such as the first plexus to choose the clean water centrifugal pump for pumping clean water, the hot water centrifugal pump for pumping hot water, and the centrifugal oil pump for pumping gasoline.
