3 tons of air can be equipped with a large power circulating pump

3 tons of air can be equipped with a high power circulating pump--- with Wilo's PH-101 can be satisfied.

Selection of air source heat pump water pump:

1 flow, 2 Yang Cheng.

The flow rate is determined based on the load carried by the fluid.

There is a conversion formula between load and flow. Air conditioners generally have a temperature difference of 5 degrees. How much do you exactly, bring it yourself.

It can be calculated by the thermodynamic flow method: q = . t 3600q = heat load (kw).

cp = specific heat at constant pressure (kj kg.) ℃）

r = specific gravity of the medium (kg m3) -1000 (water) vs = flow rate of the medium (m3 h) -1

t = temperature difference ( )5

Yang Cheng is determined according to the system resistance. (Worst point).

Every project is different, and it is not something that can be explained clearly in one sentence or two.

Pipes with different diameters have different resistance along the way under different flow rates and different temperatures.

Generally, it is calculated as follows. Closed system.

Determination of chilled water pump head.

1.Water resistance of evaporator of refrigeration unit: generally 5 7mh2o; (Please refer to the product catalogue for specific values).

2.Water resistance of the surface cooler or evaporator of the terminal equipment (air handling unit, fan coil unit, etc.): one.

Generally 4 6mh2o; (Please refer to the product sample for specific values)3The resistance of the return water filter is generally 3 5mH2O;

4.Water resistance of water separator and water collector: generally one is 3MH2O;

5.Resistance and local resistance loss along the water pipeline of the refrigeration system: The resistance along the way is generally the specific friction resistance (80

120pa m) per multiplied by the length of the pipe. The local resistance is 50% of the resistance along the way

To sum up, the head of the chilled water pump is the sum of the above resistances.

Summary. How much can 10 horsepower air be equipped with a circulating pump: it depends on the length of the entire circulating pipe, the height difference, and the number of elbows, and generally chooses a hot water circulation pump with a height length of more than 25 meters and a flow rate of 7 10 cubic meters.

How much can 10 horsepower air be equipped with a circulating pump: it depends on the length of the entire circulating pipe, the high sensitivity is poor, and the number of elbows touches the simple wheel, under normal circumstances, Xiaoxin chooses a hot water circulating pump with a length of more than 25 meters and a flow rate of 7 10 cubic meters.

PH-254 silent pump is used for the use of horse-air energy. If it is in the same plane as the water tank, and it is next to the water tank, the 10p air source is PH-254.

I have 10 horsepower air energy at home, and how big a circulating pump is suitable.

Radiators installed at home.

If the meter can determine the hydrostatic water pressure of the customer's unit, and the operating conditions, it is best to give the rated flow rate and head, that is, the static pressure, and basically determine how much horsepower to choose the circulating pump. It is generally recommended to control it within 10 horses, and sometimes it is necessary to combine the negative mountain and load characteristics of Ke Tang Weihui to choose a variable frequency pump (if it is a common system, it is generally more suitable for a fixed motor circulation pump).

Honey, refer to it.

My dear, follow what I sent, refer to it.

Summary. A 320W circulating pump cannot be used directly to calculate how many squares it can carry, because its power is not proportional to the required heating area. The power of the circulating pump is mainly related to the length of the circulating pipeline, pipe diameter, flow rate and other factors, and is also affected by the resistance of the pipeline.

Therefore, calculations need to be made according to the specific heating system parameters to determine the suitability of the circulating pump and the appropriate power size. In general, it is recommended to have a professional HVAC engineer do the calculation and design to ensure the normal operation of the system.

I bought a fish tank and wanted to go home and put it in the car, and I wanted to use the electric belt circulation pump in the car, okay.

The following aspects need to be considered when using the power supply belt fish tank circulating pump in the car:

Whether the power supply is sufficient: the safety of the rotten shed: the use of the power source on the car needs to pay attention to safety issues, to avoid short circuits, fires and other accidents caused by poor wiring or other reasons. Transportation problem: The water in the fish tank needs to be transported stably.

It is recommended that you understand the output power of the on-board power supply before using the on-board power supply with fish tank circulating pump to ensure sufficient power supply. At the same time, pay attention to safety issues to ensure that there are no potential safety hazards during use. It is best to make the source of the fish tank be transported quietly with a fish tank transport vehicle specializing in the Ming Laughing Industry to avoid the fish tank rupture caused by the shaking of the water waves.

If it's just for a short distance, that's fine; If you are a long-distance friend, it is still recommended that you weigh the above precautions for pro.

<> "Generally speaking, a 100-watt circulating pump can bring 9 square meters, and 320 can bring 29 square meters, so when choosing the power of the circulating pump, you must choose the size of the circulating pump according to the actual area of the home. If the area of the home is relatively large, you need to choose a circulating pump with a larger power to achieve the effect when used.

What problems should be paid attention to when installing a circulating pump.

1. Pay attention to inspection.

In order to prevent the inlet and outlet of the circulating pump from having foreign bodies and blockage, it is necessary to check the pipeline system, and it is best to flush it to remove the debris in the pipeline and prevent the debris from winding in the operation of the circulating pump.

2. Pay attention to installation.

When installing, do not use too much force, but do it gently, or not use too much force, it is easy to cause damage to the circulating pump. In the installation, for the inlet and outlet and other positions to connect the union to the line, whether it is disassembly, or installation will be more convenient, especially in the later stage of failure, it will save some effort.

3. Pay attention to the wiring.

In order to ensure the safety of the circuit, it is necessary to match the wire of the appropriate specification, which can be determined according to the power of the circulating pump, so that the connecting wire not only includes the live wire and the neutral wire, but also connects the ground wire, so as to ensure that it is safe to use.

How much can 300 square meters of air be used to shoot the circulating pump Hello dear, 1. Consider from the voltage requirements: s=250w*100m (50*5%)=square millimeters, 250w circulating pump can actually bring square millimeters 2, from the calculation of current requirements: i=250 [.

If my answer is helpful to you, please also give a thumbs up (rate in the lower left corner), look forward to your like, your chain is very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

The power of the circulating pump is in kilowatts.

The working principle of the circulating pump is to circulate the water, and the pump used is called the circulating pump, for example, the hot water in the plumbing and heating pipeline is circulated by the circulating pump. The circulating pump adopts excellent hydraulic model and advanced manufacturing technology, which greatly improves the performance and service life of the pump.

A circulating liquid pump for transporting reaction, absorption, separation, and regeneration of absorption liquid in the device. Generally, a single-stage centrifugal pump is used. The flow rate of the circulating pump is medium, and the flow rate of the pump changes relatively little under stable operating conditions.

It has a small and low head and is only used to overcome the pressure drop in the circulatory system. Low-head pumps are available.

800 watts per hour.

The power of the circulating pump is 50 watts 25 tons per hour, 100 watts 33 tons per hour, 150 watts 36 tons per hour, 300 watts 48 tons per hour, 400 watts 55 tons per hour, 500 watts 60 tons per hour, 600 watts 70 tons per hour, and 800 watts 100 tons per hour.

Summary. Refer to the specific flow rate and head to configure the pump, and to configure two pumps, one is a circulating pump, one is a booster pump. Among them, the circulating pump is configured according to the flow rate of water, and the heat production of the heat pump is multiplied by the rated water flow, if the heating capacity of the heat pump is 150kw, then its rated water flow rate is cubic meters per hour, as long as the circulation pump with this value of water flow rate can be selected.

If the booster pump is configured, it depends on the head, which needs to be calculated by considering the height of the water, how many bends need to be passed, the length of the pipeline, etc., as long as you choose the booster pump that meets its head.

Referring to the specific flow rate and head to configure the pump, Tongcha should also be equipped with two pumps, one is a circulating pump, and the other is a booster pump. If the heat production of the heat pump is 150kw, then its rated water flow rate is cubic meters per hour. If the bridge tunnel is equipped with a booster pump, it depends on the head, which needs to take into account the height of the water, how many bends need to be passed, the length of the pipeline, etc., as long as you choose the booster pump that meets its head.

According to the water flow rate of the unit and the resistance of the system, the flow rate of the pump and Yang Cheng are selected, such as the 100-meter pipe large stack needs to choose the water pump of the 5-meter Yang Cheng. There are many brands and types of hot water circulating pumps. We can choose according to the temperature of the heated water, the temperature of the water is more than 80 degrees Celsius, or the water quality is corroded, and the high-temperature pump with stainless steel shell is required.

In terms of brand, we choose to choose an internationally renowned brand, German Wilo.

Selection of hot water circulating pump for heating engineering: we take 4 horsepower air energy heating heat pump in 7 with a heating capacity of 14 kilowatt hours as an example, and the hot water is circulated in the floor heating pipe or fan coil unit to cool down 5 degrees at a time, so how much flow of hot water circulation pump does the 5 horsepower air energy heating heat pump need? 14kwx860** for kcal) 5 = 2408 liters per hour cubic meter hourly flow of hot water circulating pump, of course, the higher the outside temperature, the greater the heat production of the air energy heat pump, the need for a larger water pump, otherwise it is easy to cause compressor overheating protection, Yang Chang should be based on the height difference between the hot brother water circulation pump and the end (fan coil, radiator, floor heating coil), the number of elbows, the horizontal distance, and a single floor heating pipe coil (length not more than 100 meters).

Ground management. Kiss and look carefully at the answer, I talked about it.

Ok, I'm not a professional, I don't understand that! Just tell me how big a circulating pump can four horses of air carry for the floor heating pipe?

The pump within 100 watts is not necessarily, the imported pump is much more expensive, and the joint venture is cheaper The installation of rock chaos and can be done at any time Geothermal pipeline cleaning depends on the quality of the heating water, the rough water quality is not good to clean once in 3-5 years, and the water quality is good to clean once in about 7 years The pump, which is generally silent and silent, with a power of 100 watts and a power of 20 hours, is a kilowatt-hour of electricity, and water leakage is a problem of installation and construction However, there is still a water volume that grabs the upstairs and downstairs.

Summary. Hello 10 horsepower air can use 500 watt circulating pump, if it is fluorine circulation, there is no need for a circulating pump between the water tank and the host, and the main engine itself has its own water pump if the water is circulated.

Hello dear 10 horsepower air can use 500 watts Xunkai this ring pump, if it is a fluorine circulation, there is no need for a circulating pump between the water tank and the host, and the main engine itself will return to the water pump from the manuscript.

10 hp air energy, with this pump is not too big.

Pro, their power is 10 horsepower = kilowatt 10 = kilowatt. That is, it should be equipped with a kilowatt water pump.

Yours is on a boiling cycle or a water cycle.

Water cycle. If the water is circulated, the main engine will have its own water pump.

It's been a few years since I bought it.
