How much does a complete set of intelligent variable frequency constant pressure water supply equipment cost?

2025/9/28??????view:
Answer from water supply expert:
    The price of a complete set of intelligent variable frequency constant pressure water supply equipment is mainly determined by factors such as the flow rate, head, power, number of pumps, equipment material, and control method of the equipment, and cannot be determined by a single aspect. Because the number of water supply households, the number of floors, and the total number of buildings in each high-rise building are different, the flow rate, head, power, specifications and models, and equipment size of the equipment are also different, so the price is also different. (For example, if the water supply household number of Project 1 is 150 households and the floor number is 12 floors, and the water supply household number of Project 2 is 200 households and the floor number is 20 floors, then the flow rate, head, equipment size, and power of Project 1 and Project 2 are different, so their prices are definitely different.)

Introduction to complete intelligent variable frequency constant pressure water supply equipment

    The complete set of intelligent variable frequency constant pressure water supply equipment is a new generation of pressurized water supply equipment independently developed and produced by Zhongying Water Supply. It can automatically adjust to meet the user's constant pressure variable water supply requirements. The Zhongying complete set of intelligent variable frequency constant pressure water supply equipment is a pressurized water supply equipment composed of two or more pumps connected in parallel, using PLC and PID frequency control. It automatically adjusts the speed of a single pump or the input and output of multiple pumps through a frequency converter, so that the entire water supply equipment always maintains a working state of energy saving and constant pressure operation. It has the characteristics of reliable operation, high intelligence, and simple operation. The pressure of the water supply network remains constant, and the entire water supply system always maintains the optimal state of energy saving. The ideal water supply mode with constant pressure of the water supply network and simple operation.


Advantages of complete intelligent vector frequency conversion constant pressure water supply equipment
1. Solve the problem of low water pressure and maintain constant pressure.
2. The use of constant pressure variable frequency water supply ensures that the water supply pressure remains constant throughout the building.
3. Humanized design to avoid water pollution caused by the use of top water tanks
4. Replacing the traditional roof water tank water supply method. Eliminating the source of water pollution, without pollution.
Reduce construction costs, increase space area, save energy, and reduce floor space
6. Eliminate traditional roof water tanks, reducing the stress on the building, simplifying the structure, and lowering costs.
7. Compared to typical water supply equipment, it can save 30%-60% on electricity and is easy to install
8. The system achieves fully automatic intelligent control, with functions such as manual/automatic switching, timing rotation of main and auxiliary pumps, pressure adjustment, constant pressure, high and low voltage protection, phase loss protection, leakage protection, overload protection, overheat protection, water shortage protection, water leakage detection and compensation, stopping without water, and instantaneous tripping protection.

9. The human-machine interface can be customized according to user requirements, allowing for visual remote adjustment, monitoring, and maintenance.


Installation, use and maintenance of complete intelligent vector frequency conversion constant pressure water supply equipment:
1. The installation site for this equipment should be well-ventilated, dust-free, and dry, with an ambient humidity range of -10℃ to 40℃. Outdoor installations should be equipped with rain-proof and lightning-proof measures.    
2. To facilitate equipment installation and maintenance, a space of 70cm should be reserved around the equipment, and a space of 1.5m should be reserved at the manhole. Drainage ditches should be provided on the surrounding ground.    
After selecting the site, the foundation should be properly treated, and the tank support base should be poured with concrete or built with bricks and stones. After the base is cured, the tank body should be hoisted and placed steadily, and then the accessories should be installed and the power supply should be connected.    
Before testing, close the water supply valve and check the condition of each sealing valve. No leakage is allowed. After starting the machine, pay attention to the direction of rotation of the pump. When the pressure gauge pointer reaches the upper limit, the pump will automatically stop. Open the water supply valve to supply water normally. If you need to supply water at a fixed time, you can turn the selection switch to the manual position.   
5. The pump unit of this equipment should be inspected regularly. If leakage is found in the centrifugal pump and check valve, the flange screws should be tightened or the asbestos root should be replaced in a timely manner. Check that the pump foot bolts are not loose to prevent damage to the machine. The automatic control system of electrical appliances should be waterproof, dustproof, and regularly inspected for line insulation, loose connecting bolts, and intact fuses. The external pressure gauge should be wrapped with transparent material to prevent damage.
