Which brand of variable frequency water pump is good?

Question 1: What brand of variable frequency pump is the best? What brand of variable frequency pump is good? What brand of variable frequency pump is good? In the era of modern energy conservation and environmental protection, variable frequency pumps are increasingly welcomed by users. It is still difficult to find suitable and economical variable frequency pump equipment when purchasing. At present, domestic variable frequency pumps are basically equipped with variable frequency control cabinet to control the operation of the pump, which is not ideal in cost and installation. In addition, the control cabinet takes up more space and is more troublesome to install and debug. So what brand of variable frequency pump is good? At present, the technology of frequency conversion controller directly loaded on pump motor is only adopted by foreign water supply equipment manufacturers such as the United States and South Korea, and only a few domestic manufacturers have begun to adopt it. Apollo has this technology, and it is an early manufacturer of variable frequency water pumps in China. Cabinet-less variable frequency water pump is a variable frequency water supply equipment in Apollo. In addition to all the characteristics and advantages of non-negative pressure water supply equipment, it also has many functional characteristics that non-negative pressure water supply equipment does not have because of its unique structural characteristics. Each variable frequency water pump is attached with a frequency converter, which is integrated with them. The frequency converters can communicate with each other, and multiple frequency conversion pumps automatically switch, with low noise and superior cost performance. Because of this feature, the control cabinet is omitted in the water supply system, which greatly simplifies the structure and improves the reliability of the system. In the water supply system with multiple variable-frequency pumps, the communication and intelligent decision-making between the inverters replace the role of the control cabinet to complete the tasks of starting and stopping a single variable-frequency pump, switching between multiple pumps, and simultaneous operation of multiple variable-frequency pumps.

Germany Willard, Denmark Granford, domestic New Territories, South China and other pumps can meet the requirements of variable frequency pumps, while Naichuan Automation provides variable frequency pumps, which can provide customized variable frequency pump solutions.

Question 4: Which brand of variable frequency water pump is better? Frequency conversion is to change the power supply frequency, so as to adjust the load, reduce power consumption, reduce loss and prolong the service life of equipment.

The core of frequency conversion technology is frequency converter, which realizes the automatic adjustment of motor running speed through the conversion of power frequency, and changes the fixed power grid frequency of 50Hz into the changing frequency of 30- 130 Hz. At the same time, the adaptive range of power supply voltage reaches 142-270 V, which solves the problem that the instability of power grid voltage affects the work of electrical appliances. The technology to realize AC control by changing AC frequency is called frequency conversion technology. The difference between variable frequency air conditioner and fixed frequency air conditioner: comfort

Constant frequency air conditioner uses on-off to adjust the room temperature. The temperature control range is 2℃, and the room temperature fluctuates widely, so people will feel uncomfortable and easily get "air conditioning disease". The inverter air conditioner just started to run at high speed, and when the room temperature reaches the set temperature, it turns to low frequency operation, and the temperature control range is 0.5℃, which keeps the indoor temperature constant and makes it more comfortable, especially suitable for the elderly and children to sleep.

The difference between variable frequency air conditioner and fixed frequency air conditioner: energy saving

Inverter air conditioners are not started as frequently as fixed frequency, and will not generate instantaneous large current again and again; After starting, the inverter air conditioner runs at the maximum frequency, and when the room temperature reaches the set temperature, it turns to low frequency operation, because the low frequency operation has a high energy efficiency ratio, which can greatly save energy compared with the constant speed machine. According to statistics, the efficiency of full DC inverter air conditioner is about 40% higher than that of fixed frequency air conditioner, and that of ordinary DC inverter air conditioner is about 30% higher than that of fixed frequency air conditioner.

The difference between variable frequency air conditioner and fixed frequency air conditioner: cooling and heating capacity.

The higher the frequency of inverter air conditioner compressor, the higher the running speed of compressor, the stronger the cooling and heating capacity, and the faster the indoor temperature changes. After start-up, the inverter air conditioner runs at the maximum frequency, which can reach above 130Hz, and its cooling and heating capacity is 2-3 times that of the constant-speed air conditioner (50Hz), and the room cooling or heating speed is1-2 times faster than that of the constant-speed air conditioner. Make people get comfortable temperature environment quickly.

The above points are the differences between variable frequency air conditioning and fixed frequency air conditioning. Compared with fixed frequency air conditioning, variable frequency air conditioning can realize the unity of comfort and energy saving. According to the experts' prediction of Comfort 100 Network, with the introduction of China's air conditioning renewal energy efficiency standard, the traditional AC inverter air conditioner will be eliminated in the next 1-2 years, and the DC inverter air conditioner dominated by Daikin will occupy the mainstream of the air conditioning market, accounting for more than 85% of the market share, and become the preferred product of domestic air conditioners in the future.
