Frequency conversion water supply equipment price list, how much is frequency conversion water suppl

How much is the **trend? This question is being answered, generally speaking, the frequency conversion water supply equipment manufacturers include three main parts: equipment configuration, equipment, and equipment warranty time.

Frequency conversion water supply equipment**is based on the head, flow and other parameters to determine the size of the pump used, **not necessarily, about 2-5-10-million, if you need a real **, the customer must provide the head, flow details data can be obtained**!! Don't thank me because I'm just sharing. Thank you!

Frequency conversion water supply equipment

First of all, the procurement unit contacts the water supply equipment manufacturer on the Internet to communicate the details of the water supply equipment, and the manufacturer drafts a reasonable ** list according to the requirements provided by the customer and the premise of meeting the engineering requirements. It is then handed over to the customer and waiting for a response.

A complete set of water supply equipment ** process is: first, investigate the actual situation of the water supply equipment use site, and carry out water supply equipment**; Then sign the purchase contract, make a down payment and order production; The second is the completion acceptance and handover of relevant information, as well as the guarantee of after-sales service in the later stage. Equipment** refers to a complete list of costs for the entire water supply plant.

It not only includes the selection of water supply equipment, but also some labor costs, accessories, auxiliary materials, freight and other items.

If you follow the code, check the GB 50015-2003 (2009) edition of the "Code for the Design of Building Water Supply and Drainage", page 46, the calculation method of the effective volume of the air pressure tank. (It's hard to enter the formula here).

If it is according to the specification, the effective volume is generally large, occupies a large area, and the procurement cost is high. In practice, the diameter or 1000 is generally selected.

When the domestic water supply system uses pneumatic water supply equipment to supply water, it shall comply with the following provisions:

1. The minimum working pressure in the pneumatic water tank should meet the water pressure required at the water distribution point in the most unfavorable part of the pipe network;

2. The maximum working pressure in the pneumatic water tank shall not make the water pressure at the water distribution point at the maximum water pressure of the pipe network greater than 3. The flow rate of the pump or pump group (the average pressure gauge in the air pressure tank should correspond to the flow rate of the pump head) shall not be less than the times of the maximum hourly water consumption of the water supply system;

4. The adjustment volume of the pneumatic water tank is calculated as follows:

v（q2）=α(a)q(b)/4n(q)

V(Q2) - the adjusting volume of the air pressure tank (m3).

Q (b) - the outlet flow rate of the pump or pump set (m3 h) (a) - safety factor, desirable.

n(q) - the number of times the pump is started within 1 hour, it is advisable to use 6-8 times 5, the total volume of the air pressure tank is calculated according to the following formula:

vq=βvq1/(1-αb)

VQ - the total volume of the pneumatic water tank.

VQ1 - the water volume of the pneumatic water tank, should be equal to or greater than the adjustment capacity B - the working pressure ratio in the pneumatic water tank (with absolute pressure gauge), it is advisable to use the volume coefficient of the pneumatic water tank, diaphragm pneumatic water tank to take.

Here's how it works:

First, the pressure of the water supply network is stable. The equipment is automatically controlled by the microcomputer into a closed loop, which can restore the changing pressure to normal within seconds, and the pressure adjustment accuracy is about 5% of the unset value.

Second, the protection function is complete, the operation is safe and reliable, and the operation is convenient. The main engine of the equipment adopts the imported frequency conversion governor, which has the protection functions of under-voltage, over-voltage, over-current, overload, short circuit, overheat, overload, etc., and the trouble-free use reaches more than 100,000 hours. The power distribution control part of the equipment adopts the intelligent control principle, which is convenient and practical to operate, and convenient for non-professionals to use.

Third, the water supply pressure of ZBW series water supply equipment is 10-200m, and the water supply volume of a single set of equipment is 10 to 5000 square meters, which can be applied to the supporting transformation of large, medium and small tap water, and can be used for enterprise units, residential areas, rural production, living and office water.

Fourth, it occupies a small area, has less investment and has a short installation cycle. Compared with other older equipment, the equipment saves 3 to 16 times the floor space, and 3% to 16% less than the cost of building a water tower. The equipment is small in size, easy to assemble, and short in transportation and installation cycle.

Fifth, high efficiency and energy saving. The equipment adjusts the power consumption of the motor according to the user's actual water consumption and automatic detection of pressure use, so that the equipment is in a high-efficiency working state.

Sixth, the water supply function is complete and the safety factor is high. When the equipment fails, the emergency function can be activated to continue the water supply. The variable frequency water supply equipment and the municipal water supply network are automatically connected to the grid, and have the function of double frequency conversion, which can meet the normal pressure and flow of production and domestic water, and can be converted into high-pressure and high-flow water supply in the event of a fire, which can be realized and multi-purpose.

Frequency conversion water supply equipment is an unguarded, fully automatic operation of water supply equipment.

Generally, the floor is relatively high, and it is necessary to use it when the tap water pressure is not enough.

Changsha Huadu is quite professional in doing this.

How much is the frequency conversion water supply equipment? Water supply equipment** is necessary to have head data, flow and other parameters to determine the size of the pump used, **not necessarily, about 3-50,000 between, if you need a real **, it is necessary to provide head, flow details**!! Don't thank me because I'm just sharing my specialty.

It depends on your power and floor height, and whether there are active and standby lines.

The general design is PLC, frequency conversion, high and low pressure area pumps, as well as power distribution cabinets and various auxiliary materials

How much is 1 set of non-negative pressure variable frequency water supply equipment? This question is being answered again, in generalWater supply equipmentThe manufacturer includes three main parts: equipment configuration, equipment and equipment warranty time.

Water supply equipment** is based on the head, flow and other parameters to determine the size of the pump used, **not necessarily, about 2-5-10-million, if you need a real **, the customer must provide the head, flow details data can be obtained**!! Don't thank me because I'm just sharing. Thank you!

Equipment**, you have to provide the flow and head, or the specific number of households, the height of the community, otherwise it can't be given to you**.

The ** of variable frequency constant pressure water supply equipment is determined by the number of water supply households, flow rate, head, pump model, and the material used in water supply equipment. According to the size of the parameters, the general frequency conversion constant pressure water supply equipment** is between 30,000 and 600,000.

To understand that the manufacturers of variable frequency constant pressure water supply equipment are informal, you can check through the enterprise and Tianyan.

1. Search for the name of the water supply equipment manufacturer you want to know. Look at the business address on the business license. The general address is what the road and what number of the enterprise is generally a more formal water supply equipment enterprise (such as searching for Changsha Zhongying Water Supply, showing the address of No. 120, Xinxing Road, Yuhua District, Changsha City, Building 2, which means that the strength is regular).

If the business address is what road, what building, how many rooms and how many rooms (for example, Room 1010, 10th Floor, Xingwei Famous Block, No. 260 Shaoshan Road, Yuhua District, Changsha City), it is generally a sales company or an informal water supply equipment enterprise, because water supply equipment is a large machinery, and it is impossible to produce it in a building or office building. (In the building, 3C (QCQ) product certification, energy-saving certification, and water-saving certification cannot be done, and it must be consistent with the production address and business address).

2. Search for the name of the water supply equipment manufacturer you want to know. Look at the company's qualification certificates, patents and software copyrights. If the enterprise has a lot of patents, a lot of software copyrights, and a lot of qualification certificates, the water supply equipment manufacturer is generally more powerful and formal.

Such as patents, software copyrights, 3C (QCQ) product certification, energy-saving certification, water-saving certification, drinking water safety and health license, ISO9001 quality system certification, environmental management system certification, occupational health and safety management system certification, after-sales service system certification, intellectual property certification are all necessary qualifications for water supply equipment manufacturers. If there are no such qualifications, it means that the company has no strength and is not formal.

Therefore, by checking the business address and qualification certificate of the enterprise is an important way to understand whether a company has strength, and it is not easy to be fooled, because all the information of the enterprise can be queried on the Internet. It's easy and convenient!

The question you asked is a bit too simple, but what is the specific amount of traffic? What is the head? Or describe the engineering situation, and then according to these to determine, frequency conversion constant pressure water supply equipment is not the same for each set, like Xing Hori water supply will generally send technical personnel to your project to design the first plan, which is also to ensure the correct use of frequency conversion constant pressure water supply equipment.

How much is a set of variable frequency constant pressure water supply equipment? This question is being answered again, generally speaking, frequency conversion constant pressure water supply equipment.

The manufacturer includes three main parts: equipment configuration, equipment and equipment warranty time. Frequency conversion constant pressure water supply equipment** is based on the head, flow and other parameters to determine the size of the pump, **not necessarily, about 2-5-10-million, if you need the real **, the customer must provide the head, flow detailed data can be obtained**!!

Don't thank me because I'm just sharing. Thank you!

The price is not certain, first of all, it depends on the power of your motor, generally speaking, the greater the power, the higher the price of the inverter, and the greater the cost of making a control cabinet.

Set the pressure! The speed of the motor is controlled according to the signal of the pressure sensor, and the specified pressure is reached!

In general, a device that converts alternating current with a fixed voltage and frequency into alternating current with variable voltage or frequency is called an inverter. The device first converts three-phase or single-phase alternating current to direct current (DC). Direct current (DC) is then converted to three-phase or single-phase alternating current (AC).

The inverter changes the output frequency and voltage at the same time, that is, changes the n0 on the motor running curve, so that the motor running curve moves down in parallel. Therefore, the inverter can make the motor obtain a larger starting torque with a smaller starting current, that is, the inverter can start the heavy load.

The inverter has basic functions such as voltage regulation, frequency regulation, voltage stabilization, speed regulation, etc., and applies modern science and technology, which is expensive but has good performance, complex internal structure but simple to use, so it is not only used to start the motor, but is widely used in various fields, all kinds of power, all kinds of shapes, all kinds of volumes, all kinds of uses, etc. With the development of technology and the reduction of costs, inverters will be more widely used.

First of all, the use of these two equipment is not the same, frequency conversion water supply equipment needs a water tank, no negative pressure does not need a water tank, and the probability of failure without negative pressure is relatively low, as long as the pump is used well, there is basically no big problem. Moreover, there is no negative pressure, and it is still energy-saving compared to the variable frequency water supply.

Therefore, there is still no negative pressure and the operating cost is low.
