Oil-free air compressor to adapt to the use of the industry

Air compressor general machinery processing industry: used in the enterprise's own production, including: boiler and pressure vessel manufacturing; oxygen generator and automobile turbine manufacturing; gold processing and mining machinery manufacturing; electric power and motor manufacturing; chemical machinery manufacturing machinery, Environmental protection machinery, construction machinery, textile machinery, light industrial machinery, dyeing and finishing machinery, knitting machinery, plastic machinery, food machinery supporting industries: spraying machinery, environmental protection machinery, boilers, knitting machinery, stop mixing machinery, CNC machine tools, etc.

Air compressors are widely used, commonly used in food and pharmaceutical industries, using compressed air to stir slurry, oil well fracturing, starting of large marine diesel engines, blowing weft yarn with compressed air in jet looms instead of shuttles, submarine sinking, shipwreck salvage, submarine oil exploration, hovercraft, etc. The compressor is directly driven by the electric motor to make the crankshaft produce rotary motion, and drive the connecting rod to make the piston produce reciprocating motion, causing the cylinder volume to change.

Improve the utilization rate of air compressor volume: due to the three reasons of manufacturing, installation and operation, the clearance volume in the cylinder is always inevitable, and the clearance volume not only directly reduces the effective volume of the cylinder, but also the residual high-pressure gas must be expanded to the suction pressure before the cylinder can begin to suck in fresh gas, which is equivalent to further reducing the effective volume of the cylinder. It is not difficult to understand that if the pressure ratio is larger, the residual gas in the clearance volume will expand more and the effective volume of the cylinder will be smaller.

Air compressor is a kind of equipment that can compress air. Its application is very important for many enterprises and can help large enterprises to complete production effectively! From this point, we can see the importance of air compressor equipment! This is also because of the wide application of air compressors. Now the type of air compressor on the market and more and more manufacturers, which is more common and commonly used is the energy-saving air compressor, it can not only effectively compress the air, but also can save energy, save a lot of money for the enterprise.

Permanent magnet variable frequency air compressor is how to save energy?

Frequency conversion air compressor is made for energy saving. General production includes permanent magnet frequency conversion and ordinary frequency conversion. In the world of variable frequency air compressors, the most energy-saving is the permanent magnet variable frequency air compressor. Energy saving is only relatively speaking, and its ultimate goal is to save money. Then the "energy saving" meaning of permanent magnet variable frequency air compressor is no longer single, and it even includes the later maintenance and repair costs. Now let's take a look. How does the permanent magnet variable frequency air compressor save energy?

1) Energy-saving effect of permanent magnet variable frequency air compressor The biggest advantage of permanent magnet variable frequency air compressor is energy saving, which can generally save energy by 10% ~ 35%. The amount of energy saving depends on the working conditions of the air compressor and the setting of the parameters of the frequency converter. The biggest factor is the working conditions of the air compressor. When the customer's gas consumption fluctuates greatly, the better the energy-saving effect will be. The most direct data is the proportion of no-load time to all working hours. Therefore, in the process of selling the inverter control cabinet, we must first understand the customer's working conditions and get the following data:

the model of the machine; whether the working mode is ON/OFF control or MOD control; loading working time and total working time;

the working hours of the air compressor every day and how many days a week, how many hours a year; The setting of the pressure band; If there is an electric energy meter, copy down the degree of electricity. What is the local electricity bill for one kilowatt hour.

After knowing the above various situations, you can calculate how much money can be saved in a year when the energy-efficient controller is installed. Of course, this energy-saving analysis is very complicated, and there is special software to calculate how much electricity can be saved under specific working conditions.

2) The maintenance cost of permanent magnet variable frequency air compressor is reduced

due to the use of high-efficiency energy-saving control system, the software start of the air compressor reduces the electrical impact on the electrical components of the motor, and the starting current is small, which extends the life of the motor contactor. The software start of the air compressor reduces the mechanical impact on the equipment, and the motor bearings, main engine bearings and gear boxes all extend the service life. The high-efficiency energy-saving controller control device makes the air compressor in a loading state for most of the time. All kinds of related solenoid valves and pneumatic components greatly reduce the number of actions, so the failure rate of electrical and mechanical parts is greatly reduced. Feeding the cost of replacement parts and labor costs.

In addition, the frequency converter control device makes the air compressor in the loading state most of the time, and the air inlet filter is always in the forward filtering state. When unloading, the air filter is in the reverse filtering state. The use of the frequency converter greatly reduces the time of reverse filtering of the inlet filter and prolongs the service life of the filter element.

3) Permanent magnet variable frequency air compressor reduces the capacity of the factory's power grid

when using star-delta start, the starting current is still relatively large, when the factory power grid capacity is limited, it will cause the upstream air switch trip, the use of high-efficiency energy-saving controller can save the cost of factory power grid expansion.

4) Permanent magnet variable frequency air compressor to reduce production losses

the permanent magnet variable frequency air compressor uses a high-efficiency and energy-saving controller, and monitors more than 20 parameters, current, voltage, speed, torque, and power consumption at the same time. The system has a high degree of intelligence. It makes the air system more stable and reliable, reduces downtime and reduces production losses.

5) Permanent magnet variable frequency air compressor can reduce noise

when the displacement decreases, the speed of the motor slows down, and the noise of the air compressor is much smaller than that of the full speed operation. The time of unloading operation is reduced, and the noise of venting is also reduced.

The five advantages of permanent magnet variable frequency air compressor are almost all in order to reduce the cost. So far, is this air compressor enough to make you excited. It can not only reduce costs, energy saving and environmental protection, work efficiency and noise pollution is also very low. When choosing a permanent magnet variable frequency air compressor, you must ask the sales staff about the relevant energy-saving meaning, recognize the brand, and avoid buying counterfeit products and causing excessive losses.
