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.

Specialized motor for air compressor

1. Imported brand bearings, protection class IP54, insulation class F, suitable for harsh environments such as large dust and high temperature.

2. IE3 high-efficiency motor uses less electricity and reduces your cost of use.

3. The motor is designed according to the 1.2 coefficient, and the starting torque is large, which can meet the requirements of full life use under various working conditions.

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

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

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

Three filters

Air filter: the filter area exceeds 150% of the normal requirement, low the inlet pressure loss , and high energy efficiency ;

Oil filter: The design of the imported oil filter with enlarged glass fiber material is adopted. The rated processing capacity of the oil filter is ≥1.3 times of the circulating oil volume. The filtering accuracy is high and the durability is good.

Oil separator: imported glass fiber material oil core, good filtration effect, low oil core pressure loss.

Inlet valve

Inlet valve: low flow speed test, low pressure loss, reduce energy consumption;

Minimum pressure check valve: low pressure loss, precise control, ultra-fast repositioning to ensure that the user's air does not return.

Temperature control valve: Mixed flow temperature control valve: The unit is equipped with a mixed flow temperature control valve to ensure that the unit is more convenient to start in a low temperature environment, and to ensure the unit is in the best performance state by controlling the oil supply temperature of the air end

FAQ

1. Material and life of permanent magnet motor

A:
The magnetic steel of the permanent magnet synchronous motor we use is neodymium iron boron permanent magnet material. Can be used for a long time under normal use
2. Comparison of oil-cooled and air-cooled motors

A:
Oil-cooled motors use lubricating oil for cooling, which has high cooling efficiency and is less affected by ambient temperature. Air-cooled motors use cooling air for cooling.
3. Can you work 24 hours a day?

A:
YES
4. How many years can this machine be used?

A:
The design life of our unit is 30 years.
