185kw 250hp silent stationary oil free best deal on air compressor for food industry

185kw 250hp silent stationary oil free best deal on air compressor for food industry

With variable speed control technology, the displacement of the compressor can be perfectly combined with the user’s gas consumption, completely avoiding the loss of unloading power.In the state of intermittent gas use, the zero load of the soft start avoids the peak of current and torque, so the unit can start and stop indefinitely. Really achieve 0~100% steeple speed change, maximally control the generation of useless work.

variable frequency air compressor advantage

  1. Rotor material

The screw rotor of 185kw 250hp silent stationary oil free best deal on air compressor adopts SAE 1141 forged steel, whose quality, wear resistance and rotor strength has a great improvement, compared to other rotors using ordinary cast steel.

  1. Processing technology

The screw rotor adopts a grinding process.  After the rotor is milled, surface grinding must also be carried out to greatly improve the machining accuracy of the rotor. All that reduces air back flow and triangular leakage during compression, and improve efficiency.

  1. Bearing

The bearing is the main moving part of the 185kw 250hp silent stationary oil free best deal on air compressor, which bears the load of the rotor during the rotation and ensures the gap between the rotors.

185kw 250hp silent stationary oil free best deal on air compressor adopts the top B-10 aerospace heavy-duty wear-resistant bearing produced by SKF of Sweden, with a design life of up to 130,000h. The rolling bearing adopts heavy-duty cylinder and roller cone bearing.

Through the linear contact, the bearing can withstand a uniform load that can withstand greater radial and axial forces than a typical roller bearing. That greatly extend the life of the mainframe.

Particularly speaking, the quantity of bearings at the exhaust end of the 185kw 250hp silent stationary oil free best deal on air compressor air end is 2 more than that of any other brand air end. It can withstand greater radial and axial forces, or reduce the load on each bearing.

That will greatly prolong bearing life. The limitation of the bearing size lies in the rotor center distance. Larger bearings can use larger center distances, and the load is higher, which means, the service life is longer.

The large diameter rotor provides installation space for large diameter bearings. 185kw 250hp silent stationary oil free best deal on air compressor use 56% larger bearings than their competitors, with low bearing loads and low speeds.

Therefore, the bearing life of the 185kw 250hp silent stationary oil free best deal on air compressor rotor is up to 100,000h (except for human factors). Most other competitors choose SKF’s common industrial bearings, which have small diameters, large bearing loads, fast speeds and a service life of only 50,000 hours.

  1. Transmission gear

185kw 250hp silent stationary oil free best deal on air compressor transmission gear adopts German original AGMA 13 (aerospace grade) gear, which has strong wear resistance and service life of 300,000h. The gear could ensure that the efficiency of the 185kw 250hp silent stationary oil free best deal on air compressor during the entire service life (more than 30 years) is not affected by the wear and tear of the gear.

variable frequency air compressor features

When the required pressure is set, the unit will always maintain a constant pressure supply of ±0.1 bar; when the gas consumption is large, the pressure will remain unchanged and the rotation speed will be automatically compensated to ensure the supply of gas;

185kw 250hp silent stationary oil free best deal on air compressor remains unchanged and the speed is automatically reduced to meet the air volume that is only sufficient.

185kw 250hp silent stationary oil free best deal on air compressor use advanced control, monitoring and communication systems. Through the Internet, users can easily obtain technical assistance from suppliers all over the world.

The frequency conversion soft start avoids electrical shock and avoids mechanical shock; eliminates the unfavorable factors of long-time high-speed operation of the unit; no contractor to avoid electrical contact failure; eliminates the high pressure of 2 bar and reduces the probability of system leakage. Energy saving, environmental protection, equipment in place, and immediate activation.

Any 185kw 250hp silent stationary oil free best deal on air compressor unit does not require special installation foundation, low-speed fan and modern vibration isolation and noise reduction measures, so that the compressor operates with very low noise, so it is easy for users to place on the production site, as long as the equipment is in place, fast pipe connection , can be shipped immediately.
