Product Desciption
compressor with rotary-type positive-displacement mechanism
I. Introduction:
Variable frequency conception:
Our variable frequency series screw compressor takes advantage of the stepless speed regulation of the frequency charger, and start screw air compressor gently through the controller or the PID regulator inside of the controller to improve the start and operation mode of the motor.
Prediction and evaluation of energy saving:
If the air compressor frequently upload and unload during the operation and particularly the steady pressure output is needed, it is necessary to use air compressor frequency changer to control air compressor to achieve the effect of energy saving in a certain range.
Steady pressure:
The air compressor frequency changer aims at a the larger fluctuations of air volume. Internal PID regulator can quickly adjust the response. Compared with the limit switch control of operating with motor in constant frequency, the stability of the air pressure output increases exponentially, keeping on a constant point.
Start with no impact:
For the frequency changer has the function of the soft start, the start-up current is 3 times lesser than the power frequency startup. So the impact of the startup is smaller.
Variable flow control:
Based on the PID regulator and the actual air consumption to adjust the motor speed at a real time, to control the emission output and to achieve a equilibrium air supply. When low consumption, the air compressor can sleep automatically to reduce the energy loss. The optimized control further improves the energy-saving efficiency.
Better voltage adaptability of AC power supply
Due to the over modulation technique used in frequency changer, while in low AC power supply voltage, it still outputs the enough torque to drive the motor to work. While in high AC power supply voltage, it will not lead to a higher voltage output to motor.

IV. Company Introduction SHANGHAI HONEST COMPRESSOR CO., LTD. is one UK wholly-owned compressor company, which was situated in shanghai in 2004, based in technical cooperation with European air end manufacturer and British O.S.G. OSG Shanghai specializes in manufacturing the world-class screw compressors and air purification equipments.
In order to meet customers' expectations and requirements, OSG shanghai integrates the compressing system to embody the merits of reliability, energy saving, silence, convenience. OSG Shanghai had obtained the compressor production license (certificate No: XK06-010-00597), quality certificate and general machinery certificate, ISO 9001:2008 certificate and CE certificate.
OSG has established a nation-wide service system of 40 offices, and provided comprehensive services, such as consulting, training, repairing, spare parts supplying, etc. OSG shanghai also do OEM for trading companies and agents, according to their requirements.
OSG shanghai welcome customers and engineers all over the world to study, train and cooperate. Welcome to OSG Shanghai.
V. Company Advantages
1.Enormous potentiality, long history
Shanghai Honest Compressor Co., Ltd. is one British wholly-owned enterprise. Currently in China, OSG has set up three major manufacturing bases (Shanghai Honest Compressor Co., Ltd, Zhejiang Ulite Tools Co.,Ltd., Guangdong OSG welding), five Manufacturers. Meanwhile we cooperate with the European world-advance air end manufacturer. OSG shanghai possesses a complete production, sales and after-sales service system. OSG has 40 offices and more than 80 after-sales service centers, and products are sold to more than 20 countries.
2. Advanced configuration, world-renowned components, abundant production experience.
The control system is the most advanced. The controller is designed and manufactured by Schneider, France. It is equipped with the large Chinese-English liquid crystal display screen. It can monitor more than 20 main operating parameters, and has the functions of fault recording, maintenance and alarm shutdown. It can achieve efficient intelligent control, unattended.
Remote control: the computer processor can directly check the user's real-time operating system. Combine the reliability, energy saving, practicality in one. remote control can start, stop, load, unload the compressor and also other local control can be carried out. The operation, alarm and fault and relative local information can be monitored. (detailed description followed)
Remote control function:
Multiple compressors remote centralized control: reduce system pressure, reduce energy consumption, real-time monitoring.
Dual pressure setting: Two system pressure bands can be set manually or automatically to optimize energy use and reduce operating costs.
Delayed secondary shutdown: This function controls the motor to run only when needed, allowing the motor to run less and minimize the energy consumption.
