LG标准系列电动固定螺杆空气压缩机

☆排气压力:0.7-1.3Mpa
☆排气量:0.8-35M 3/Min
☆电机功率范围:7.5-200kW
产品简介:
经济的运行成本
系统采用0-100%的排气量无级调节。当用气量减小时,排气量跟着减小,电机的电流也同时降低;当不用气时,空压机空车运转,空车过久自动停机。当用气量增加时,恢复重车。节能效果优。
良好的环境适应性
超常的冷却系统设计,特别适用于亚洲高温、高湿环境。优良的隔振技术和降噪措施,使螺杆空压机的安装无须专用的基础,只要留出小的通风和维护空间,就能安置好您的压缩机。
螺杆转子型线的设计特点:
一、完全实现“曲面对曲面”啮合,从而有助于形成流体动力润滑膜,降低通过接触带的横向泄漏,提高压缩机效率;以及改善转子的加工、检验性能。
二、采用“大转子、大轴承、低转速”的设计思路,转速比其他品牌低30~50%,可以降低噪声和振动,降低排气温度,提高转子刚性,延长使用寿命,减小对杂质和油碳化物敏感性。
三、功率范围4~355KW,其中18.5~250KW均为不带齿轮箱直联,200KW和250KW更为4极电机直联,转速低至1480转/分。
四、全面符合甚至超越GB19153-2003《容积式空气压缩机能效限定值》国家标准的要求。


$LG standard series electric fixed screw air compressor



Exhaust pressure: 0.7-1.3mpa

Exhaust volume: 0.8-35m 3 / min

Motor power range: 7.5-200kw

Product introduction:

Economic operation cost

The system adopts stepless regulation of 0-100% exhaust volume. When the air consumption decreases, the exhaust volume decreases, and the current of the motor decreases at the same time; when the air is not used, the air compressor runs empty and the empty car stops automatically for too long. When the air consumption increases, the heavy vehicle will be recovered. Energy saving effect is the best.

Good environmental adaptability

Extraordinary cooling system design, especially suitable for high temperature and humidity environment in Asia. Excellent vibration isolation technology and noise reduction measures, so that screw air compressor installation without special foundation, as long as the minimum ventilation and maintenance space, you can place your compressor.

Design features of screw rotor profile:

1、 Fully realize the "curved surface" engagement, which helps to form hydrodynamic lubrication film, reduce the lateral leakage through the contact belt, improve the efficiency of the compressor, and improve the processing and inspection performance of the rotor.

2、 Adopting the design idea of "big rotor, big bearing and low speed", the speed is 30-50% lower than other brands, which can reduce noise and vibration, reduce exhaust temperature, improve rotor rigidity, extend service life and reduce sensitivity to impurities and oil carbides.

3、 The power range is 4-355kw, in which 18.5-250kw is direct coupling without gearbox, 200kW and 250KW are more direct coupling of 4-pole motor, and the speed is as low as 1480 rpm.

4、 It fully meets or even exceeds the requirements of gb19153-2003 "limited value of energy efficiency of positive displacement air compressor".
