Regarding the question of submersible pumps, does the submersible pump have an impact on the submers

The most important thing is the flow rate and head. First of all, we need to figure out the flow rate, that is, how long it takes to pump and how much water, for example, the pool is 1 cubic meter, we hope to pump it in 10 minutes, then the flow rate should be 6m3 h, and combined with the water output speed of the well water stock, don't pump empty. Then there is the pressure or head, 8+8+17 (per layer) = 33m is necessary.

of blah blah blah blah blah.

Summary. Hello, glad to answer for you. If it's a submersible pump, it won't.

However, when shutting it down, it is important not to take too long of it, because if it is in operation all the time, the surrounding water temperature will increase, which is very bad for cooling and wastes electricity. It is easy to burn out the pump, and it is also easy to damage the outlet pipe! If you want to control the water flow, it is best to add a pressure stabilizing tank device!

It doesn't matter, it's just that the pressure inside the pump is a bit high.

Does the submersible pump make the water slower and have an impact on the submersible pump?

Hello, glad to answer for you. If the eggplant is a submersible pump, it will not. However, when it is turned off, it should be careful not to take too long, because if it is in a state of operation all the time, the surrounding water temperature will increase accordingly, which is very unfavorable to the Leng faction, and it is also a great waste of electricity.

It is easy to burn out the pump, and it is also easy to damage the outlet pipe! If you want to control the water flow, it is best to add a pressure stabilizing tank device! It didn't have any effect, but the pressure inside the pump was a little too much.

Hello, Xun Song Zhi is happy to answer for you. A small outlet will only increase the outlet pressure and will not burn out the pump. If the outlet is reduced, it may cause the submersible pump to burn out.

This is not directly related to the nominal power, water flow or head of the submersible pump. In the case of a more serious shrinkage stool at the water outlet, the whole submersible pump is in a certain degree of mumin locked, and when running in this state for a long time, the motor current value of the submersible pump itself is very large, and it is easy to burn.

Question 1: What is a submersible pump Submersible pump is a kind of water pump that puts the pump directly in the water, eliminating the water inlet pipe, eliminating the trouble of ordinary water pump water diversion, which is very convenient and trouble-free. I am not afraid of water, because it is placed in the water to cool itself and can be used for a long time.

The size of the pumping volume and the height of the water lifting can now basically meet the general needs of individuals in small quantities and large quantities of factories. This is the submersible pump, the pump that is placed in the water. , you can find out.

Question 2: What is a submersible pump Submersible pump is a kind of pump that puts the pump directly in the water, eliminating the inlet pipe, eliminating the trouble of ordinary water pump drainage, very convenient and trouble-free, any pool, puddle, bucket, water tank water level is very shallow to work, to meet your pumping and drainage requirements. I am not afraid of water, because it is placed in the water to cool itself and can be used for a long time.

The size of the pumping volume and the height of the water lifting can now basically meet the general needs of individuals in small quantities and large quantities of factories. This is the submersible pump, the pump that is placed in the water. , you can find out.

Question 3: What is the meaning of the head of the submersible pump Suction lift is also called "maximum self-priming height" (can also be understood as "degree of self-priming"). That is, the maximum height at which the micro pump can automatically suck water up without water diversion (the vertical distance between the pump outlet and the liquid surface to be pumped).

Generally, when the water source is lower than or equal to the position of the pump, the pump needs to have self-priming ability. For example, when traveling outdoors, you need to pump water from the river, and it is best to use a miniature pump with self-priming capacity (it is impossible for people to run into the river to add some water to the inlet pipe first). Or the liquid pumped is corrosive, inconvenient to add water and so on.

For example, there is a kind of water pump, the model is called a certain BSP series, the volume is not large, but the nominal suction lift can be up to 4 meters, and it can indeed be used to 4 meters without water intake, which is relatively high in the micro pump.

In micro pumps, not all pumps have a self-priming capacity ("suction lift").

Some centrifugal pumps do not have self-priming ability, and water must be diverted for the first time. Although some miniature pumps also have self-priming ability, there is often a gap between the standard "suction lift" and the vertical height that can pump water under "all air in the inlet pipe", and may even be less than half. Therefore, when selecting the pump, the suction lift is a more important parameter.

Head The head of the pump refers to the height at which the pump can lift water, which is usually expressed in h and the unit is m. The head of the centrifugal pump is based on the center line of the impeller and is composed of two parts. The vertical height from the centerline of the impeller of the pump to the water surface of the water source, that is, the height at which the pump can suck up the water, is called the suction head, referred to as the suction lift; The vertical height from the centerline of the impeller of the pump to the water surface of the outlet pool, that is, the height at which the pump can press the water up, is called the pressurized water head, referred to as the pressure range.

i.e. pump head = suction head + pressurized head It should be pointed out that the head indicated on the nameplate refers to the head that can be generated by the pump itself, and it does not include the loss head caused by the frictional resistance of the pipeline water flow. When choosing a water pump, pay attention not to be ignored. Otherwise, you won't be able to pump water.

<>1. Purchase. When purchasing a submersible pump for travel, you should pay attention to its model, flow rate and head. If the selected specifications are not appropriate, it will not be able to obtain sufficient water output and the efficiency of the unit will not be brought into play.

In addition, the direction of rotation of the motor should also be clarified, some types of submersible pumps can produce water when they rotate forward and in reverse, but the water output is small and the current is large when reversing, and its reversal will damage the motor winding. In order to prevent electric shock accidents caused by electric leakage when the submersible pump is working underwater, a leakage protection switch should be installed.

Second, the installation of the town spike.

When installing a submersible pump, the cable should be overhead and the power cord should not be too long. Do not stress the cable when the unit is launched, so as not to cause the power cord to break. The submersible pump should not sink into the mud, otherwise it will cause poor heat dissipation and burn out the motor windings.

Peb. 3. Use.

1.Try to avoid turning on the machine at low pressure. The power supply voltage can not differ from the rated voltage by 10%, the voltage is too high and the motor will overheat and burn out the winding, the voltage is too low, the motor speed will drop, if it does not reach 70% of the rated speed, the starting centrifugal switch will be closed, causing the starting winding to be energized for a long time and heating or even burning out the winding and capacitor.

The rotary lobe pump should not switch the motor on and off frequently, because the electric pump will produce backflow when it stops, and if it is turned on immediately, the motor will be started under load, resulting in excessive starting current and burning out the windings.

2.Do not let the pump run overload for a long time, do not pump water with large sand content, and the dehydration time of the electric pump should not be too long, so as not to overheat the motor and burn out. During the operation of the unit, the operator must observe whether the working voltage and current are within the specified value on the nameplate at any time, and if it does not meet the requirements, the motor should be stopped to find out the cause and eliminate the fault.

3.Usually check the motor more, if it is found that the lower cover is cracked, the rubber sealing ring is damaged or invalid, etc., it should be replaced or repaired in time to prevent waterproof penetration into the machine.

1. Do not rotate in the opposite direction. Longzhu submersible pumps are divided into single-stage pumps and multi-stage pumps, according to common sense, the head of single-stage pumps is lower, while the head of multistage pumps is higher. With a single-stage water pump, it is recommended that you distinguish the direction clearly.

Although the submersible pump can come out of the water regardless of whether it is positive or negative, it is still recommended that you do not rotate forward. If it is reversed, then there is a risk of damaging the motor windings. And to be honest, the submersible pump single-stage pump is in an inverted state, and the water output is still less, so it is better to rotate forward.

In addition, I would like to remind you that you can carefully check the single-stage pump of the submersible pump before putting it into the water to see if the rotation direction of the single-stage pump of the submersible pump is normal. If the Chunwu section is abnormal, it should be adjusted in time, and it can only enter the water after normal.

2. Do not overload the operation. Whether it is people or equipment, as long as it is overloaded, it will cause certain damage to itself, and the same is true for stainless steel submersible pumps. As I told you above, the lift of a single-stage submersible pump is generally relatively small, so for those working fields that require a high-lift submersible pump, a single-stage submersible pump cannot be used.

If you have to use a submersible pump single-stage pump, you should pay attention to it during use to prevent the current value from exceeding the normal range and burning the equipment.

3. High frequency start. Moreover, Taizhou Langnuo Pump Industry **** wants to say that when the single-stage pump of the submersible pump of Longzhu Pump Industry is closed, the submersible pump will have a backflow phenomenon. At this time, if everyone presses the start button to let the submersible pump run, it may damage the motor and make the motor load start.

When the motor load is started, the starting current becomes very large. To a certain extent, it will inevitably cause many problems in the equipment. At the same time, the service life of the equipment is shortened.

Therefore, when using submersible pumps, you must not commit this taboo. In general, if you want to start the submersible single-stage pump again, you need to wait at least five minutes.

1. The submersible pump cannot be dehydrated.

2. The submersible sewage pump cannot be started immediately after it is stopped, and it can only be started after the water storage in the pipe is returned. If the water cannot be discharged after starting, the machine should be stopped immediately to find out the cause and eliminate it.

3. When the submersible pump is put into the water or raised to the water surface, the lifting rope must be pulled, and the cable must not be pulled. If you want to transport, disassemble or overhaul, you should first cut off the power supply.

4. The submersible pump should not be started frequently, and should not be used for drainage and irrigation of water or mud water with high sand content.

5. After starting, if the impeller reverses, it should be stopped immediately.

6. The submersible pump can be controlled by the pump control cabinet.

Introduction to submersible pumps

The submersible pump is an important equipment for lifting water from deep wells. When in use, the whole unit dives into the water to work, extracting groundwater to the surface, which is domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and can also be used for fountain landscape.

Hot water submersible pumps are used for hot spring bathing, and can also be used for extracting groundwater from deep wells, and can also be used for water lifting projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and water for people and livestock in high mountainous areas, and can also be used for air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction sites.

Water pump is an important mechanical part of life, in the city's water supply, industrial production and other environments need to use various forms of water pumps, the emergence of water pumps has also helped people solve a variety of transportation problems, and there are many types of pumps, people can choose different types of pumps according to different requirements, submersible pumps are more common types of water Huaibi pumps, how to use submersible pumps.

The submersible pump is a kind of mechanical equipment that is put under water for pumping water up, the advantage of the submersible pump is that it can meet the high-pressure working environment, and the head of the submersible pump is very high, which can better solve the water treatment in the underground, coal mine and other environments, the types of submersible pumps are also very many, and the use options from household to industrial environments are not the same, and the carrying and operability of the submersible pump are also very good, so the use of submersible pumps in life is more extensive.

The use of the submersible pump is very simple, put the pump into the environment to be used when using it, turn on the switch to operate, the submersible pump should be filled with water and deflated before starting to prevent the pump from being emptied, and the relevant cables and wires should be checked to ensure that there is no opening before it can be used.

1.Installation: Install the submersible pump in the water, and make sure that the inlet of the pump is a certain distance from the bottom to avoid inhaling debris such as sediment. At the same time, make sure that the cable connection is secure and will not be washed away by the water pat flow.

2.Turn on the power supply: connect the cable to the power supply to ensure that the power supply is stable and the voltage meets the requirements of the submersible pump.

3.Start: Press the start button, the submersible pump starts to work, sucking water or other liquids into the pump, and transporting the liquid to the place where it needs to be through the rotation of the impeller.

4.Maintenance: Regularly check the operation of the submersible pump, clean up the debris and dirt in the pump, and keep the pump clean and unblocked. At the same time, pay attention to the maintenance of cables and motors to avoid moisture or damage.

5.Shutdown: After use, press the stop button to stop the submersible pump from working, disconnect the power supply, and disassemble the submersible pump for maintenance and maintenance.
