11كيلوواط 15 ضاغط هواء حلزوني صناعي ذو سرعة ثابتة من HP

This 11kw screw compressor uses the Hanbell screw airend. It has high efficiency and low speed. The rotors adopt the third-generation tooth shape. So it has the advantages of low noise, توفير الطاقة, stability, and high reliability.

هذا 15 hp rotary screw air compressor uses a low-speed special motor. It has high stability. There is approximately a 5% efficiency improvement over comparable products. The motor does not require current excitation. علاوة على ذلك, the motor has a temperature protection function. The permissible overload current is high. The protection class is IP54. So effectively protects the motor. Increases its service life.

The air compressor is with an intelligent microcomputer control system. Guaranteed fully automatic intelligent operation. It can monitor the exhaust pressure, درجة حرارة, and other field data. لذا, the operator can adjust the 15 hp industrial compressor quickly and easily.

ملكنا 15 hp rotary screw air compressor uses a low-speed fan. It has a long life span. It uses a large fan surface design and can effectively enhance the cooling effect of the fan. The cooler and fan can be disassembled independently. And there is a 20% cooling margin.

The air filter has a high capacity for dust and dirt. The flow resistance is low. It can filter out tiny particles in the compressed air. Dust removal effect can reach 99.5%.

Oil filter uses high-density filter media. The surface is treated with nano-plating. بجانب, the pore size of the filter element is uniform. It has low resistance and high interception capacity. Filtration precision is also high. So it can effectively remove impurities in the lubricating oil. فضلاً عن ذلك, the separator core adopts an advanced three-stage oil-air separation design. The oil content is kept below 3 جزء في المليون. Thus ensures high-quality compressed air output.

The former uses a star-delta method to start at 5-8 times the rated current. It has a high impact on the grid. Tends to cause grid instability. The latter starts by means of a PID regulator inside the frequency inverter. So it can start smoothly.

The former has a higher no-load rate. Because of idling, it wastes more energy. بجانب, it takes longer to stop. But VSD air compressors can eliminate idling. It can increase efficiency by an average of 10%. So it can avoid no-load energy waste.

In actual production, our air requirements are constantly changing. For fixed-speed air compressors, only meets this change by frequent loading /unloading. If the customer requires a pressure of 6 حاجِز, the compressor will be set to load at 6.5 حاجِز. في 7.5 حاجِز, it will unload. So it will run continuously between 6.5 و 7.5 حاجِز. The average pressure is 7 حاجِز. إنه, it’s 1 bar over. Therefore naturally results in more energy waste.

But for the VSD air compressor, it does not need to set the loading and unloading pressures. And it can stabilize the pressure within ±0.1 bar. This means that the pressure is basically stable at 6.5 حاجِز. Or even lower. So it significantly reduces the operating pressure of the system. Finally realizes lower energy consumption.

There are limits to the specific power of a screw air compressor’s first-class energy efficiency standard. على سبيل المثال, 22kw/7bar screw compressor: Power frequency air compressor is 6.5. And VSD air compressor is 6.9,. There is a 6.15% difference between the two. For 11kw 15 hp/7bar rotary screw air compressor: Fixed speed air compressor is 6.8. And variable speed air compressor is 7.5. There is a 10.29% difference between the two.

We measure the specific power values. For the former, calculate it at 100% of the full load. And for the latter, calculate it at 100%, 70%, و 40% of the full load. فضلاً عن ذلك, the weighting factors are 25%, 50%, و 25% على التوالى.

Assume that the air compressor is operating at full load. The latter compressor also has to bear the power consumption of the inverter (5-8%). The former airend can choose 100% of the load as the optimum number of revolutions. But the VSD airend is different. For the sake of the load 70% weighting factor, it is possible to choose 70% of the load. لذلك, if run at full load, the former is more energy efficient than the latter.
