Durable, efficient and stable air end

Durable, efficient and stable air end

1. The design idea of "large rotor, large bearing, low speed" is adopted to reduce noise and vibration and increase the life and stability of the host.

2. The tooth surface is processed by the German KAPP rotor grinder to create a high-precision rotor, which is the first guarantee of high efficiency and stability of the air end.

3. Adopt a new type of 5: 6 asymmetric rotor tooth shape, high-precision three-coordinate measuring machine for comprehensive measurement, increase the air capacity by 5% -10%

4. All imported quality bearings are used.

High-quality and efficient coupling

High-quality and efficient coupling

1. The coupling is a torsionally elastic coupling with failure protection function, which can effectively damp and reduce the vibration and shock generated during the operation.

2. The elastic body is only under pressure and can withstand greater loads. The drum-shaped teeth of the elastic body can avoid stress concentration.

Stable and reliable electronic control system

Stable and reliable electronic control system

1. The control system has the functions of voltage detection, three-phase unbalance detection, overpressure, overtemperature, overload, and overrun alarm high alarm functions, real-time protection of the unit, automatic monitoring of operating conditions, automatic loading and unloading, sleep and restart And other functions, no need to be supervised by someone.

2. The standard Internet of Things system allows you to see the running status of your machine on your phone.

3. The intelligent control system can be set in both Chinese and English, and can realize the joint control of multiple units.

4. Choose high-quality electrical components, and the contactors are imported brands.

5. Emergency stop function, a push-type emergency stop switch is installed in a prominent position of the unit, and it can stop immediately in an emergency.

Inner rotor fan

Inner rotor fan

1. IP44 cooling fan, Class F insulation;

2. Compared with the outer rotor fan, the inner rotor fan has higher air pressure, more air volume, and better cooling effect;

3. Due to high wind pressure, the cooler and filter are less likely to be blocked
