Single-stage low pressure compressor

1.Stable and efficient dedicated low-voltage host

• The host specially developed for low pressure conditions optimizes the screw profile and internal pressure to improve the efficiency of the host
• Adopt the design idea of “large rotor, large bearing, low speed” to reduce noise and vibration, and increase the life and stability of the host
• The tooth surface is processed by a rotor grinder to create a high-precision rotor, which is the first guarantee for the high efficiency and stability of the hos

2.High-efficiency permanent magnet synchronous motor

• IP54 protection level, more stable and reliable than IP23 in harsh environments ;
• Low-temperature rise design, higher efficiency, extending the service life of the motor
• Use ceramic-plated bearings to completely eliminate the impact of shaft current on the bearings
• It is made of rare-earth permanent magnet materials, with large torque during starting and running, and small current during starting and running
• Reasonable magnetic field design, magnetic density distribution, the energy-saving motor has a wider working frequency range and low operating noise

3.High-quality and efficient coupling

• The coupling is a torsion elastic coupling with a failure protection function, which can effectively prevent and reduce the vibration and impact generated during operation
• The elastic body is only subjected to pressure and can withstand greater loads. The drum-shaped teeth of the elastic body can avoid stress concentration.

4.Silent centrifugal fan

• The whole system adopts centrifugal fans, which are more efficient and energy-saving ;
• Compared with axial fans, centrifugal fans have higher wind pressure, lower noise, and more energy-saving ;
• Using frequency conversion fan control, the oil temperature is constant, which greatly extends the service life of the lubricant ;
• Due to the high wind pressure, the cooler and filter are less likely to be blocked.

5.Advanced and reliable electronic control system

• The large-size color LCD touch screen has a good human-machine communication interface and the touch screen has functions of preventing accidental touch and sleep
• Customized vector inverter, perfectly matched with the motor, low frequency and high torque ;
• According to the characteristics of low pressure, special programs are developed to fully monitor various parameters of the machine, and automatically control the state of the machine without special supervision

6.Auxiliary oil supply pump

• The auxiliary oil supply system is added to the unit to ensure that the unit (especially the bearing) can get sufficient oil supply in the later period of long-term operation, and the unit runs more stable and has a longer life
• High-temperature resistance, stable oil pressure at the outlet
• The oil pump uses a self-heating structure, which is simple and reliable

7.High-quality three filters

• The filtration area of the air filter exceeds 150% of the normal requirement, with low intake pressure loss and good energy efficiency;
• The oil filter adopts an enlarged imported glass fiber material oil filter design. The rated processing capacity of the oil filter is ≥1.3times the circulating oil volume, with high filtration accuracy and good durability

• The layout of the three filters is reasonable, maintenance is convenient, and downtime is reduced.

8.Special valve group

• Intake valve: It adopts a low-pressure special normally-closed butterfly valve, which is stable in work, high in air volume control accuracy, noise reduction design inside, low cavitation noise, and long service life
• Minimum pressure maintenance valve: low-pressure dedicated valve, accurate opening pressure, to ensure stable pressure in the barrel, ultra-fast return to the seat, strong sealing, to ensure that the gas does not return, low-pressure loss, and high efficiency
