50 HP 37 KW energy saving 35% (EVA) PM VSD marine air compressor

permanent magnet variable frequency air compressor advantage

First, the high-efficiency and energy-saving full load, the permanent magnet motor of the permanent magnet variable frequency screw air compressor produces the maximum gas volume under the minimum energy consumption; when the permanent magnet variable frequency screw air compressor load rate is lower than 20%, it always maintains up to 95% The efficiency of operation, to achieve first-class energy efficiency.

Compared with the power frequency screw air compressor, the energy saving is over 39.7%; compared with the ordinary frequency conversion air compressor, the energy saving is 10%.

For example: one customer has a maximum gas consumption of 13 m3/min, a minimum gas consumption of 6 m3/min, a load rate of 60% (load time/total working time), and runs 6000 hours per year, saving electricity: 6000h* (1-60%) ) *75kw * 35% = 63000kwh (not including 10%-13% loss caused by pressure loss).

Second, durable Durable maintenance permanent magnet variable frequency screw air compressor uses rare earth permanent magnet synchronous motor to directly drive the screw host, 120 ° C without loss of magnetism, life expectancy of 10 years.

The screw main unit and the motor of the permanent magnet variable frequency air compressor share the same main shaft, and do not need belts and couplings, and the transmission efficiency is 99%. The motor has no bearing and eliminates the bearing fault of the motor.

Third, the maintenance cost of permanent magnet variable frequency screw air compressor permanent magnet motor volume is smaller than the ordinary three-phase motor host 1/2, light weight 1/3, the overall size is significantly reduced.

The one-piece screw main unit is 1/2 smaller than the ordinary main machine, and the lubricating oil required for each maintenance is about 50% of the ordinary screw type air compressor, and the maintenance cost is greatly saved.

permanent magnet variable frequency air compressor features

KINGBULL bipolar compression displacement increased by 13% to 15%. In some factories with large gas consumption, this gas increase of 10% is quite considerable, 13% is converted into electricity costs about 10 W-15 W a year. So why do many big companies choose dual-level now?

Since the two-stage compression technology uses two pairs of rotors, the volume will be larger than the traditional single-stage, and the cost of factory R&D and manufacturing will increase accordingly. The corresponding increase in the first phase will be able to recover the cost after the equipment is put into use for about 2 years. After that, the annual electricity savings are the cost of the company.
