20 cubic variable frequency air compressor procurement which is good?
First understand the characteristics of the permanent magnet variable frequency air compressor.
What are the characteristics of permanent magnet variable frequency air compressor?
1. The essence of permanent magnet high-efficiency frequency conversion is to control the rotation of the motor space magnetic field.
2. The stator winding generates a rotating magnetic field synchronized with the power frequency through three-phase alternating current.
3. The basic composition of permanent magnet synchronous motor: stator winding, rotor, body.
4. The rotor is a permanent magnet made of permanent magnet material, which starts to rotate under the action of the rotating magnetic field generated by the stator winding.
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 inverter. One of the biggest causes
the element is the working condition 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 the total working time.
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. Air compression
the software start of the machine 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 the most
in the loading state, all kinds of related solenoid valves and pneumatic components have greatly reduced the number of actions, so the failure rate of both electrical and mechanical parts is greatly reduced. Feed 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, the air inlet filter is always in the forward filtering state, and the air filter is in the reverse filtering when unloading.
The use of the inverter greatly reduces the time of reverse filtration 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 factory power grid expansion.
The cost.
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. Make the air system more
it is stable and reliable, reduces downtime and reduces production losses.
5) Permanent magnet inverter 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. permanent magnet variable frequency air
Shanghai granklin two-stage compression air compressor, our two-stage compression air compressor adopts water-lubricated air compressor head, while saving energy and electricity, we make the whole machine oil-free, gas oil-free, make the gas pure and oil-free, can be applied to medical breathing grade compressed gas. The permanent magnet frequency conversion two-stage compression is superior to the ordinary power frequency single-stage in energy saving efficiency.
For the air compressors used in waste incineration, the power compressors for small and medium-sized enterprises are mainly small displacement, and the flow rate is mostly below 3m 3/min. The market share accounts for "half of the country" of screw compressors, and the stock market reaches millions of units. The screw relies on the gap to seal the gas and does not have good performance in the small flow range. Small and medium-sized enterprises are cost-sensitive users, very much hope to reduce the operating costs of small displacement screw compressors, small displacement screw compressor low energy efficiency has become a pain point for small and medium-sized enterprises.
View detailsIt depends on your application scenarios, such as medical, chemical, food, electronics, and other industries that require higher gas requirements, then the "5 cubic screw air compressor price" and ordinary "5 cubic screw air compressor price" is very different. So what is the difference between a high standard "screw air compressor" and an ordinary "screw air compressor?
As the country pays more and more attention to energy conservation and emission reduction (fashionable name is carbon neutral), the application of low-pressure screw air compressor is also increasing. At present, there are three main types of low-pressure screw machines: dry screw, water spray screw, and oil spray screw.
Shanghai granklin group water lubricated air compressor factory direct sales, air compressor use: 1, can be used as air power-air after compression can be used as power, mechanical and pneumatic tools, as well as control instruments and automation devices, instrument control and automation devices, such as tool replacement of machining centers, etc.
View detailsAir compressor can operate correctly and has a long service life, excellent maintenance is important, so we must grasp the air compressor maintenance methods, master how to repair common problems. Maintenance of air compressor must do a good job in basic maintenance and maintenance of key parts
In general, oil-free air compressors are used in the food industry, because the food industry is relatively demanding. Oil-free air compressor is not only oil-free, I still give you a comprehensive popularization of the basic advantages of oil-free air compressor! First of all, the machine body
Good brands of air compressors are expensive, especially imported brands of air compressors, the price is very high, not every enterprise can afford. Brand added value in the imported air compressor reflected incisively and vividly, how to buy a good "air compressor brand", but also the right price is not easy.
View detailsHigh-end air compressors are basically monopolized by foreign brands, mainly: the price of the whole machine of major international brands is relatively expensive. Domestic products such as: granklin is not bad, the price of the whole machine is relatively cheap
Shanghai Granklin Group produces water-lubricated air compressors. The head of the machine is made of stainless steel to compress gas, coalbed methane, and some special gases, such as nitrogen and argon. Water-lubricated air compressors are divided into different series according to the different cooling methods and energy-saving methods: water-lubricated air-cooled air compressors, water-lubricated water-cooled air compressors, water-lubricated frequency conversion air compressors, water-lubricated permanent magnet frequency conversion air compressors
