In recent years, with the iteration of home appliance products, the technology of domestic home appliance parts enterprises is also constantly upgrading, under the influence of market demand and dual-carbon policy, high efficiency and energy saving has become a new requirement for home appliance products. As the main heat cycle exchange device for refrigeration, heating, refrigeration, freezing and heating water products, the improvement of energy efficiency of compressors will significantly optimize the efficiency of household appliances. In this context, the needs of major enterprises for compressors are gradually becoming unified, that is, high efficiency and energy saving, high reliability, miniaturization, integration and other requirements. If the compressor wants to achieve upgrading, the improvement of the performance of the relevant parts is the first.

The compressor is generally composed of a shell, motor, cylinder block, piston, control equipment (starter and thermal protector) and cooling system, in which the motor as the "heart" of the compressor - power supply equipment, once failure or burn, the compressor will be shut down. Therefore, the motor has the greatest impact on the safety, reliability and high efficiency of the compressor. Therefore, in order to achieve the energy-saving development of compressors, it is necessary to replace the traditional compressor motor with a more efficient and intelligent motor control, and the centrifugal switch is the breakthrough point and focus of the energy-saving upgrading of the motor.

Centrifugal switch is a switch component commonly used on the motor, usually through the rotation of the motor to generate centrifugal force, so that the displacement of the switch, cut off the circuit, as early as the 20th century, mechanical centrifugal switch has been widely promoted in the market. However, so far, the working principle of the mechanical centrifugal switch is basically unchanged and the structure is complex and prone to failure, which will affect the normal use of the motor, and the emergence of the electronic centrifugal switch has completely revolutionized the centrifugal switch products.

Compared with the traditional mechanical centrifugal switch, the electronic centrifugal switch is more intelligent and accurate by sampling the current, voltage, phase and other parameters of the motor to determine the speed of the motor. If the motor speed reaches the rated speed70% - 80%Cut off the starter to achieve the purpose of starting the motor, and improve the problem of low efficiency and poor stability of the traditional centrifugal switch.

As a motor control expert in the field of motor control for 18 years, Fuxing Weiye has launched a compressor special electronic centrifugal switch with simple, convenient and efficient characteristics, making the efficiency and reliability of the centrifugal switch have been greatly improved, compared with the traditional mechanical centrifugal switch, has the following advantages:

1Convenient installation and easy operation

As we all know, the installation of mechanical centrifugal switches is difficult, the bearing needs to be accurately processed and the process is complex, and only professional skilled workers can install. In contrast, the installation of the electronic centrifugal switch is very simple, just connect4The root wire can be placed in any position outside the motor, and ordinary workers can install it, and the operation is simple and convenient.

2, high security, more secure use

Safety is a major premise for the normal operation of the equipment, if the safety is not passed, equipment damage or even equipment explosion is possible, but the traditional mechanical centrifugal switch, its internal mechanical structure is susceptible to dust, oil, water, forming a short circuit, burn the motor; The electronic centrifugal switch is electronic clutch, higher safety, no spark, no contact, explosion-proof, not affected by any dust, oil, water, debris, etc., the use of more assured.

3Strong stability

Because the traditional electronic centrifugal switch is a mechanical structure, there will inevitably be mechanical failure, such as jamming, deviation, bending and other phenomena, but also may be due to processing, assembly and other problems resulting in motor disconnection speed or capacitor failure due to overload, resulting in unstable motor operation. The special electronic centrifugal switch for compressor developed by Fuxing Weiye has strong stability, better batch consistency, and can control the turn-off speed at75%Around. In addition, the special electronic centrifugal switch for the compressor also has undervoltage/Over duty/Overtemperature protection, from the source to protect the normal operation of the motor, can provide more stable operation and lower maintenance costs.

4High efficiency and energy saving

Compared with the mechanical centrifugal switch, the special electronic centrifugal switch for the compressor does not depend on the mechanical parts, and the burning probability is low, the waste is less, and the repair rate is controlled0.05%Within, can effectively reduce the possibility of wear and failure; At the same time, the electronic centrifugal switch control is more accurate, which can reduce energy consumption and waste, improve the overall efficiency and energy saving effect of the motor, and reduce costs and increase efficiency for enterprises.

Small size, stronger heat dissipation

Unlike traditional mechanical centrifugal switches with large volume affect motor heat dissipation, Fuxing's electronic centrifugal switches shorten the motor shaft, the motor volume design is smaller, so that the motor heat dissipation is better, can reduce the temperature rise5-10 ℃.

6Longer service life

The general service life of mechanical centrifugal switches is10Within ten thousand times, and the switching life of the electronic centrifugal switch can be as high as100Ten thousand times+It is far superior to mechanical centrifugal switches in performance and has a higher comprehensive cost performance.

To sum up, it can be seen that with the increasing requirements of compressor equipment, the electronic centrifugal switch can better meet the needs of energy-saving, efficient and high-quality development of the compressor industry due to its advantages of stability, safety, convenience and efficiency, so as to reduce the overall operating costs of the compressor motor and achieve cost reduction and efficiency, especially in the air conditioning where the energy consumption of household appliances is relatively heavy. Air conditioning compressor as an important part of the refrigeration system, to provide power for the refrigeration cycle, so in the face of cost reduction and efficiency in the field of home appliances, the market has put forward higher requirements for the energy efficiency of air conditioning compressor.

In this regard, Fuxing Weiye proposed an efficient and energy-saving, comprehensive upgrade solution for the characteristics of air conditioning compressors. First of all, the special electronic centrifugal switch for air conditioning compressor is selected to further optimize the energy efficiency of air conditioning compressor, and its high efficiency and high stability characteristics also greatly enhance the market competitiveness of air conditioning compressor. In addition, in terms of product frequency conversion module optimization, Fuxing Weiye also launched the world's first waterproof frequency conversion module, further improving the product energy efficiency and overall performance of air conditioning compressors, achieving efficient energy-saving upgrades and improving resource utilization. 

Shenzhen Fuxing Weiye as the national standard setter of electronic centrifugal switch, through the industry's advanced motor intelligent control technology to help the compressor field to achieve product upgrading and iteration, enabling the compressor industry to move towards a new path of efficient, safe and reliable development.
