Why Choose Lingyu 75hp Industrial Air Compressor
(1) Big Energy-saving Effect
The main advantage of this 55KW screw air compressor is energy saving. โดยทั่วไป, it can save energy by 10%~35%. The amount of energy saving is mainly based on two factors. นั่นคือ, the working conditions of the industrial air compressor and the parameters setting of the inverter. แน่นอน, the biggest factor is the actual application condition of the screw compressor. When the factory air consumption changes greatly, the energy-saving effect will be better. The direct data is the ratio of the no-load time to the total working time.
So how much can a 55KW 75 hp PM VSD rotary screw air compressor save energy in a year?
Assume an average load factor of 70%. The industrial air compressor runs 8000 hours per year. The energy consumption of a 55kw fixed-speed air compressor is as follows:
① Loading power consumption:
70% loading time*8000 hours/year*55KW=30800 kWh/year
② Unloading electricity consumption (นั่นคือ, no-load energy consumption):
30% unloading time * 8000 ชั่วโมง/ปี * 55กิโลวัตต์ * 45% (power consumption during unloading) = 59400 กิโลวัตต์ชั่วโมง/ปี
③ Power loss caused by control pressure:
นั่นคือ, For every 1 bar increase in pressure, power consumption increases by 7%. Saving 2bar is equivalent to saving 14% of power consumption.
70% loading time*2bar differential loss 14%*55KW*8000 hours/year=43120 kWh/year
Electric energy saved by 75 hp VSD screw air compressor = unloading electricity consumption + power loss caused by control pressure = 59400 กิโลวัตต์ชั่วโมง/ปี + 43120 กิโลวัตต์ชั่วโมง/ปี = 102520 กิโลวัตต์ชั่วโมง/ปี
Assume that each kilowatt-hour of electricity is 1 หยวนจีน. Then the 55KW variable speed air compressor can save almost 102520CNY per year.
(2) Low Maintenance Cost
The structure of screw type air compressor itself is simple. นอกจากนี้, this 55KW screw air compressor uses high-quality parts. ตัวอย่างเช่น, the airend is the Hanbell brand. The frequency converter and controller are Inovance brands. The startup disk is from Schneider. So our 75 hp screw air compressor has a long service life.
นอกจากนี้, it adopts an energy-saving control system. This air compressor uses a soft start. Electrical shocks to motors and electrical components are thus reduced. It extends the service life of the compressor motor. ในเวลาเดียวกัน, it also reduces the mechanical impact on the equipment. ดังนั้น, it extends the life of the airend bearing and the gearbox.
Because of the energy-saving controller, นี้ 55 KW air compressor is often in a loaded state. ดังนั้น, it reduces the action times of solenoid valves and pneumatic components. Their failure rate is greatly reduced.
(3) Advantaged Price
Because we are screw compressor manufacturer, our price has advantages. นอกจาก, we can customize it to your special needs. ตัวอย่างเช่น, we can print your logo on our industrial air compressor. And different colors are available. นอกจากนี้, our factory can also customize the special voltages. 220วี, 415วี, 440V and 460V three phase or 60HZ are acceptable. ที่สำคัญกว่า, we can provide full technical support.
คำถามที่พบบ่อย
ไตรมาสที่ 1: อะไร. 75 hp air compressor cfm?
A1: For our 55 เครื่องอัดอากาศแบบสกรูกิโลวัตต์, the airflow is about 350 cfm @7bar.
ไตรมาสที่ 2: What’s your lead time for this 55kw screw air compressor?
A3: If it’s a regular machine, the lead time is about 20 วัน. นั่นคือ, you need 380V/50HZ 3-phase. Because we are a factory, customization is available. But if want to buy a special OEM air compressor, the time will be about 35~40 days.
ไตรมาสที่ 3: Can I also buy some spare parts from you?
A3: แน่นอน. The air compressor filters are consumables. So we usually advise customers to purchase filters with the 55KW screw compressor. นอกจากนี้, if needed, you can also buy some air compressor valves.
ไตรมาสที่ 4: Should I buy the variable speed drive or fixed speed drive air compressor?
A4: ในความเป็นจริง, this question is mainly based on your actual air consumption. If your air consumption has significantly changed, the VSD air compressor is better. มิฉะนั้น, choose a latter power frequency 75 เครื่องอัดอากาศแบบสกรูของเอชพี.
