 The company supplies Atlas, Ingersoll Rand, Fu Sheng, Kobelco Sullair, Hitachi air compressor filter (computer controller, computer monitors, computer monitors, computer boards, computer control panel air filter, oil filter, oil separator), air compressor parts, air compressor oil, air compressor lubricants, compressor oil, air compressor supplies air compressor sales maintenance 
 The original system conditions exist 
 Start a main motor star - angle of decompression, but the starting current is still large, it will affect the stability of the grid and other 
 The safe operation of power equipment. 
 2, the main motor is often no-load operation, is a non-economic operation, serious waste of electricity. 
 3, the main motor power frequency operation resulting in a noisy compressor running. 
 4, the main electrical power frequency the impact of the starting equipment, motor bearing wear, and equipment maintenance work on mechanical volume. 




 Third, the frequency transformation program design 
 Of the problems of the original conditions of the production process requirements, air compressor frequency transformation system should meet the following requirements: 
 1, the operating status of motor frequency to keep the gas tank outlet pressure, pressure fluctuation range can not exceed ± 0.02Mpa. 
 2, the system should have a variable frequency and power frequency of the two control loops. 
 3, the system has open and closed loop two sets of control loops. 
 4, an inverter can control two air compressor group can be used to convert the switch. 
 5, according to the conditions of the air compressor, the system should be protected motor with constant torque operating characteristics of a 
 6, the effective measures to prevent non-sine wave to interfere with the air compressor controller, inverter input due to electromagnetic interference suppression. 
 7, in the case of small electric gas, the inverter in the low-frequency operation, should protect the motor winding temperature and motor noise does not exceed the allowable range. 
 8, taking into account the system after the expansion problem, the inverter should meet the requirements of working conditions in the future expansion. 

 And transform the program principle 
 By the inverter, pressure transmitter, motor, helical rotor pressure closed-loop control system to automatically adjust the motor speed, and stability within the setting range, the constant voltage control of the air pressure in the gas tank. Feedback pressure and set pressure computing, real-time control of the inverter output step, in order to adjust the motor speed, so that the air pressure inside the tank stable in the set pressure. 

 The benefits, air compressor frequency converter 
 1, energy conservation 
 2, the operating costs to reduce the Company's supply of Zhejiang Ingersoll Rand air compressor parts, Hangzhou Ingersoll Rand air compressor parts, Henan Ingersoll Rand air compressor parts. 
 3, to improve the accuracy of pressure control 
 4, to extend the life of the compressor 
 5, low noise of the air compressor 
 In the process of industrialization, the cost is often the main stumbling block of industrialization, whether the economy is in large part determine whether large-scale promotion. 

 1, the same power, high voltage motor start current, a small impact on the grid 
 2, the motor running current, power loss, saving energy 
 3, suitable for high power and large displacement screw compressor 
 Electric mobile type 
 Features: 
 1, applies to fixed and non-fixed places 
 2, the overall base, split bracket, structural design is more reasonable 
 3, box-type structure, hinge door design, maintenance is more convenient 
 4, the integration of mobile devices, use more secure, reliable 
 5, the mobile screw machine more flexible use of the venues, mobility
