Use high quality rare earth permanent magnet motor, protection level IP54/IP55. There are no motor bearings, thus avoiding motor bearing failure points.
Spin-on oil filter, the effect is higher than the conventional cartridge, effectively extending the normal service life of the host.
Adopt large heat exchange area design, improve cooling efficiency, effectively prevent the machine from high temperature, the inner wall to do anti-corrosion treatment, adapt to the more severe working conditions, extend the service life.
Large capacity oil and gas separator, high quality oil and gas separation elements and gas and liquid filter elements, with three times oil and gas separation, low oil content, to ensure high quality of compressed air.
The design with high dust holding capacity and low flow resistance can filter out the tiny solid particles in the air for better dust removal, ensuring the normal operation and economic service life of each part of the system.
Silent fan Reduce noise and power loss
Wide range of inlet adjustment, tolerance valve adjustment, small pressure loss, stable action and long life.
We use Danish brand “HOLIP”. When using inverter speed control, if the flow rate requirement is reduced, the requirement can be met by reducing the air end speed.
The most important feature of VSD air compressor is that the motor speed is changed according to the air consumption to ensure the precise matching of air volume and demand, thus achieving energy saving and constant pressure.
For example 37kw screw compressor, the average annual operation is 8,000h, and the cost of electricity is $0.1. We save electricity than ordinary screw compressor per year.
218500-165620=52880KW
52880✖0.1=$5288
each year save $5288
By adjusting the power supply frequency to regulate the compressor motor’s speed and the central compressor’s speed, the compressor’s air output and the customer’s air consumption can be consistent. This flow regulation method can avoid a large amount of energy wasted in the imported flow regulation method and is the market’s most efficient air compressor flow regulation method.
In recent years, variable speed air compressors have become popular in the market because of their unique energy-saving effect. greatly improve the efficiency of the process (variable speed does not depend on the mechanical part) and can be more energy efficient than the original fixed speed operation of the motor. Here are ten examples of reasons to use variable speed to illustrate the basic understanding of the increasing popularity of inverter applications:
(1) Control the starting current of the motor
(2)reduce the power line voltage fluctuations
(3) the power required for starting is lower
(4) Controlled acceleration function
(5) Adjustable operating speed
(6) adjustable torque limit
(7) Controlled stopping method
(8) energy saving
(9) reduce mechanical transmission parts
Yes.Air compressors create compressed air, which is then stored in tanks. There are 3 general uses.
The first is the air for pneumatic doors, the speed and reliability of pneumatic doors are generally better than electric doors.
The second is a lot of valves, check valves, instrument lights are pneumatic valves, need to use compressed air to control the valve switch and instrument indication, etc..
The third is the air for blowing, generally used to blow the pipeline.
rpm refers to the speed of the air compressor spindle per minute.
VSD air compressor is 30%~50% energy saving than ordinary air compressor, the specific amount of energy saving depends on the working condition of the air compressor and the parameter setting of the inverter. The biggest influence factor is the working condition of the air compressor, under normal circumstances, the greater the fluctuation of gas consumption, the better the energy saving effect, and the most direct data is the proportion of no-load time to the total working time. Specifically, we can measure the daily, weekly and annual working hours of the air compressor with an electric meter, so that we can count how much money is saved.
