Why Choose Lingyu 75hp Industrial Air Compressor
(1) Big Energy-saving Effect
The main advantage of this 55KW screw air compressor is energy saving. Generalmente, it can save energy by 10%~35%. The amount of energy saving is mainly based on two factors. Questo è, the working conditions of the industrial air compressor and the parameters setting of the inverter. Ovviamente, 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 (questo è, no-load energy consumption):
30% unloading time * 8000 hours/year * 55KW * 45% (power consumption during unloading) = 59400 kWh/year
③ Power loss caused by control pressure:
Questo è, Per ogni 1 bar aumento di pressione, 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 kWh/year + 43120 kWh/year = 102520 kWh/year
Assume that each kilowatt-hour of electricity is 1 CNY. 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. Inoltre, this 55KW screw air compressor uses high-quality parts. Per esempio, the airend is the Hanbell brand. The frequency converter and controller are Inovance brands. The startup disk is from Schneider. Quindi il nostro 75 hp screw air compressor has a long service life.
Inoltre, 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. Allo stesso tempo, it also reduces the mechanical impact on the equipment. Perciò, it extends the life of the airend bearing and the gearbox.
Because of the energy-saving controller, this 55 KW air compressor is often in a loaded state. Perciò, 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. Oltretutto, we can customize it to your special needs. Per esempio, we can print your logo on our industrial air compressor. And different colors are available. Inoltre, our factory can also customize the special voltages. 220v, 415v, 440V and 460V three phase or 60HZ are acceptable. Ma ancora più importante, we can provide full technical support.
Domande frequenti
Q1: What’s the 75 hp air compressor cfm?
A1: For our 55 kw screw air compressor, the airflow is about 350 cfm @7bar.
D2: What’s your lead time for this 55kw screw air compressor?
A3: If it’s a regular machine, the lead time is about 20 giorni. Questo è, 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.
D3: Can I also buy some spare parts from you?
A3: Sicuro. The air compressor filters are consumables. So we usually advise customers to purchase filters with the 55KW screw compressor. Inoltre, if needed, you can also buy some air compressor valves.
D4: Should I buy the variable speed drive or fixed speed drive air compressor?
A4: Infatti, this question is mainly based on your actual air consumption. If your air consumption has significantly changed, the VSD air compressor is better. Altrimenti, choose a latter power frequency 75 hp screw air compressor.
