The energy-saving effect of permanent magnet variable frequency air compressor.

1.The energy-saving effect of permanent magnet variable frequency air compressor.

The advantage of the inverter air compressor is that it can save 10% or 35%, and the amount of energy saving depends on the working conditions of the air compressor and the parameter settings of the inverter. The big of these factors is the working condition of the air compressor, when the user's gas consumption fluctuates, its energy saving effect is better, which directly reflects the proportion of no-load time in the entire working time.

2.Reduce the maintenance cost of permanent magnet inverter air compressor.

When the air compressor software starts, due to the application of the energy-saving control system, the electric shock to the electrical components of the motor is reduced, and the starting current is small, thus prolonging the service life of the motor contactor. The software start of the air compressor reduces the mechanical impact on the equipment, and the service life of the motor bearing, main bearing, gearbox, etc. can be extended.

The economizer control device makes the air compressor in the loading state most of the time during the execution, and various related solenoid valves and pneumatic components greatly reduce the number of actions, so that the failure rate of both electrical and mechanical parts is greatly reduced. Pay for replacement parts and labor. In addition, the frequency conversion control device makes the air compressor in the loading state most of the time, the air inlet filter is always in the positive filtering state, and when unloading, the air filter is in the anti-filtration state, and the use of the frequency converter greatly shortens the anti-filtration time of the inlet filter, and the service life of the filter element is extended.

3.Reduce the yield loss of permanent magnet inverter air compressors.

The inverter air compressor adopts an energy-saving controller, which can monitor more than 20 parameters, current, voltage, speed, torque, power consumption, etc. at the same time, and the system is highly intelligent. The unit improves the stability and reliability of the air system, reduces downtime and reduces production losses.

4.Permanent magnet inverter air compressor reduces noise.

When the exhaust capacity is reduced, the engine speed is reduced, and the noise generated by the air compressor at full speed is also greatly reduced. Reduced unloading run time and reduced release noise.

1. Compared with the reciprocating piston refrigeration compressor, the screw refrigeration compressor has a series of advantages such as high speed, light weight, small size, small footprint and low exhaust pulsation.

2. The screw refrigeration compressor has no reciprocating mass inertia force, good dynamic balance performance, stable operation, small base vibration, and small foundation.

3. The screw refrigeration compressor has a simple structure, a small number of parts, no wearing parts such as air valves and piston rings, and its main friction parts such as rotors and bearings have relatively high strength and wear resistance, and good lubrication conditions, so the amount of machining is less, the material consumption is low, the operation cycle is long, the use is more reliable, the maintenance is simple, and it is conducive to the realization of operation automation.

4. Compared with the speed compressor, the screw compressor has the characteristics of forced gas transmission, that is, the discharge volume is almost not affected by the discharge pressure, and the surge phenomenon does not occur when the discharge volume is small, and the high efficiency can still be maintained in a wide range of working conditions.

5. Spool valve adjustment is adopted, which can realize stepless adjustment of energy.

6. The screw compressor is not sensitive to the inlet liquid, and can be cooled by oil injection, so under the same pressure ratio, the discharge temperature is much lower than that of the piston type, so the single-stage pressure ratio is high.

7. There is no clearance volume, so the volume efficiency is high.

Summary. Advantages of Screw Air Compressors:

1.High reliability. The screw compressor has few parts, no wearing parts, reliable solid operation, long service life, and the overhaul interval can reach 4-80,000 hours.

2.Easy to operate and maintain. Operators do not need to be trained for a long time, and unattended operation can be realized.

3.The power is well balanced. There is no unbalanced inertia force, the machine can work smoothly at high speed, especially suitable for use as a portable compressor, small size, light weight, small footprint.

4.Adaptable. It has the characteristics of forced gas delivery, and the exhaust volume is almost not affected by the exhaust pressure.

5.Multiphase mixed transport. There is actually a gap between the rotor tooth surfaces of the screw compressor, so it can resist liquid impact, and can pressure liquid-containing gases, dust-containing gases, and easily polymerized gases.

Advantages of screw air sage compressor Sakura: 1High reliability.

The screw compressor has few parts, no wearing parts, reliable solid operation, long life, and the overhaul interval can reach 4-80,000 yuan, which is convenient for operation and maintenance. Operators do not need to be trained for a long time, and unattended operation can be realized. 3.

Adaptable. It has the characteristics of forced gas delivery, and the exhaust volume is almost not affected by the exhaust pressure. 5.

Multiphase mixed transport. In fact, there is a gap between the rotor teeth of the screw compressor, so it can withstand liquid impact and can pressure liquid-containing gases, dust-containing gases, and easily polymerized gases.

Disadvantages of screw air compressors:1High cost.

Because the rotor tooth surface is a spatial surface, it needs to be processed on the most expensive special equipment by using special tools, and the machining accuracy of its cylinder also has high requirements. 2.It cannot be used in high-pressure applications for rubber raising.

Due to the limitations of rotor stiffness and bearing life, it can only be applied to the medium and low pressure range, and the exhaust pressure generally cannot exceed and cannot be reversed. The screw compressor must not run in reverse (except for the correct steering of the cluster shouting jog), otherwise it will inevitably cause burn-in failure;

Compressed air is formed by compressing the air in the atmosphere through an air compressor, and the air in the atmosphere often contains oil, water, solid particles, dust and other impurities, etc., so it is necessary to use compressed air purification equipment to purify it.

Compressed air purification equipment includes dryers and filters.

The general screw air compressor is how many revolutions of the rotor of the power frequency are as much, and the air compressor with frequency conversion can adjust the number of revolutions according to the required air volume, and the no-load rate is greatly reduced, which saves energy and electricity. The permanent magnet does not have motor bearings, and its power transmission is simpler and the loss is lower, so it is about 7% more energy-efficient than ordinary inverters. **Permanent magnet frequency conversion "frequency conversion" power frequency.

If you don't understand, ask me again.

1. Energy-saving, the energy-saving electricity cost of the inverter screw air compressor is 10% compared with the general air compressor.

2. The operating cost of the variable frequency screw air compressor is reduced.

3. Precise pressure control accuracy of frequency conversion screw machine. Keep the pressure within a range.

4. The application of frequency conversion screw air compressor, the noise of the chassis is lower than that of the general air compressor.

5. Due to the operation of the inverter of the inverter screw machine, the fluctuation of the current when the unit is started can be reduced, and the impact on the power grid can be reduced.

6. Adapt to the air volume adjustment of air compressor. The frequency converter reaches the reference frequency at a low rate.

Frequency conversion screw air compressor under the set required pressure, the unit will always maintain a constant pressure air supply; When the gas consumption is large, the pressure remains unchanged and the speed is automatically compensated to ensure the need for gas supply; When the gas consumption is small, the pressure remains the same and the speed automatically decreases to meet the only sufficient gas volume. Therefore, it has the above advantages.

The inverter unit can automatically adjust the motor speed according to the change of the customer's gas consumption, so as to achieve the effect of energy saving. Therefore, it is more energy-saving than general power frequency units.
