In order to guide and regulate the design, processing, machinery to ensure efficient, safe and stable operation, recently, Jiangsu Province Machinery Industry Association and centralized, Jiangsu Machinery Industry Association compressor committee of experts will be drafted organizations to develop a "general oil-free screw blower with variable frequency 》The group standard, and openly solicit opinions from the society
.
The blower blows a certain pressure of air into the furnace to fully burn the fuel, increase the furnace temperature, and improve the smelting efficiency.
It was widely used in the iron smelting industry in the early days
.
With the development of air blowing equipment and the maturity of air blowing technology, the types of air blowers continue to increase, and they have been used in industries that require combustion and high temperatures such as the food industry
.
From the current market perspective, blowers include sliding vane blowers, Roots blowers, magnetic levitation blowers, and frequency conversion oil-free screw blowers

.
From the current market perspective, blowers include sliding vane blowers, Roots blowers, magnetic levitation blowers, and frequency conversion oil-free screw blowers
.
Among them, the frequency conversion screw blower is a rotary blower that passes through two spiral rotors in the casing (cylinder), and the gas is not contaminated by lubricating oil or other liquids during the pressure feeding process
.
The oil-free screw blower is a screw blower that adjusts the operating frequency of the main motor of the blower to achieve volume flow change
.
Whether it is a variable frequency screw blower or an oil-free screw blower, to maintain efficient, stable and safe operation, it must be affected by the power of the drive motor, the rated exhaust pressure, the intake temperature, the content of solid particles in the gas, the maximum size of the particles, etc.

Opinion
.
The "General Use Frequency Conversion Oil-Free Screw Blower" group standard clarifies the model, basic parameters, requirements, test methods, packaging and storage requirements
.
This standard applies to screw air blowers whose intake temperature should not be higher than 45°C, the content of solid particles in the gas should not be greater than 100mg/m3, and the maximum particle size should not be greater than 1/2 of the minimum working gap of the screw rotor in the blower body
.
However, screw blowers with a rated exhaust pressure not greater than 250kPa can also be implemented with reference to this document
.

However, screw blowers with a rated exhaust pressure not greater than 250kPa can also be implemented with reference to this document
.
In order to ensure the stable and efficient operation of the frequency conversion oil-free screw blower, the group standard stipulates that the machine should be arranged reasonably, run smoothly and reliably, and the vibration intensity should not exceed 7.
1mm/s.
The outlet end of the machine should be equipped with a safety valve, which is sensitive and sensitive.
Reliability and when the ambient temperature does not exceed 45℃, it should be ensured that the screw blower can operate normally and the oil supply temperature of the gear and bearing lubricating oil should not exceed 70℃, and the inside of the main engine should be clean, and the cleanliness index should comply with relevant regulations.

.
Of course, for the user, it is also very important to ensure the safe operation and use of the frequency conversion oil-free screw blower and avoid harm to the user
.
In this regard, the group standard has a number of regulations, including that the screw blower is not allowed to have sharp edges or protruding dangerous parts, and its exposed moving components should be equipped with safety protection devices; a red emergency stop button should be installed in a prominent part that is easy to operate , attachment surface temperature should exceed 80 ℃ safety warning and the like

.
Although the blower production industry is just in its infancy compared to foreign countries, the domestic demand for blowers is increasing.
In the future, with the development of downstream applications in food and beverage processing, boilers, sewage treatment, kitchen waste power generation and other industries, it will further stimulate the demand for the blower industry , The types of demand are also more diversified
.
The formulation and implementation of the standard for general frequency conversion oil-free screw blowers will help improve the manufacturing level of blower machines, to a certain extent, promote domestic blower companies to occupy the domestic blower application market share, and promote the healthy, high-speed and high-quality development of the industry
