Dehaha All in One 22kW PM VSD screw air compressor for laser cutting

Technical description

Part 1: Air compressor part

• Air compressor configuration table

• technical parameter

3. Main components of the air compressor

1. The equipment is produced by Dehaha Compressor Jiangsu Co., LTD.

2.the air compressor host is one of the few domestic use of the third generation of 5:6 asymmetric tooth shape single-stage compression, the gas production effect is excellent. The cooling mode is air cooling, and the unit adopts the direct connection driving mode. All the cylinders are precision castings, strong and durable, winged on the surface of the cylinder, beneficial to the heat dissipation of the compressor host.

3. The suction port of the main engine is equipped with an air filter of 2 µ m. All the materials of the coolers are aluminum plate wing structure, which has good heat transfer effect and is suitable for various environments.

4. Dehaha customized motor is a high-efficiency export motor with low failure rate and high efficiency.

4. Electrical parts

1. The air compressor is equipped with a set of air compressor controller.

2, the air compressor is equipped with a pressure signal, as well as the automatic shutdown, automatic start function.

3. Timed automatic discharge; periodic automatic discharge

4. Automatic protection: motor overload shutdown; high pressure alarm

5. Parts and components

1, the use of domestic well-known manufacturers pipe joint, good quality to ensure the sealing of the pipeline, to prevent the occurrence of pipeline oil leakage phenomenon.

6. Special design features

1, the use of the main engine motor direct connection mode, better efficiency, the lowest failure rate, the best gas production effect.

2, unique shockproof, noise reduction patent design, noise control in 72DB.

3. The oil content of air compressor is lower than 2 PPM, and the oil content is lower than 0.003 after efficient PPM

4. Automatic pressure relief system to ensure the safe start of the unit in the condition of no load, prolong the service life of the compressor, and protect the main engine and motor.

7. Description of control system of high pressure compressor unit

1. The unit is controlled by PLC, all Chinese display (Chinese and English), showing the air compressor status information, fault alarm information, parameter setting, temperature and pressure, total running time and loading running time, loading / unloading / full load display, emergency shutdown, operation mode, etc. And can record at least 30 historical alarm information, exhaust pressure, exhaust temperature history information, with automatic and manual control (automatic loading and unloading) to achieve unmanned operation of the unit.

2. The following protection is provided:

⑴ The exhaust temperature is too high protection, the nose exhaust temperature exceeds 105℃, immediately alarm and shutdown.

⑵ Electrical appliance protection, electrical fault alarm and shutdown.

⑶ Overload protection, main motor / fan motor overload alarm and shutdown.

⑷ 380V power supply misphase protection, missing phase protection shutdown.

⑸ Overpressure protection, the exhaust pressure exceeds the setting value of the alarm shutdown.

⑹ It has three alarm functions: oil and gas separator blocking alarm, air filter blocking alarm and oil filter blocking alarm

⑺ Automatic temperature control system, maintain the lubricating oil temperature through the temperature control valve is above the pressure dew point temperature, to ensure that the oil temperature is in the best state (see the description of the air compressor composition system for details).

⑻ Fault alarm device, the unit failure can timely prompt the user to replace the parts and do necessary maintenance.

⑼ The unit has the function of self-diagnosis and protection.
