Which is the best 20 cubic variable frequency air compressor to purchase

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
