Good Market Adaptability of PE Film Blower

New film blowers produced in the mechanical manufacturing industry include sheet blowers, PE blowers, multi-layer composite film blowers, color strip blowers, heat-shrinkable film blowers, etc., which meet the packaging requirements of various products on the market. High-end film blowers have won the favor of high-end commodity packaging. Nowadays, the film blower develops high-end technology, and the film blown can also be used as a variety of application technologies such as pharmaceuticals, food preservation and so on, taking the road of new type of film blower manufacturing.

A film blower with good performance shows good market adaptability in the process of film production, improves production efficiency, provides convenience for people, and promotes the harmonious development of society.

Several points to note when choosing the frequency converter of the film blower:

1) If the frequency converter is going to run with a long cable, measures should be taken to suppress the effect of the long cable on the ground coupling capacitance to avoid the insufficient output of the frequency converter, so in this case, the capacity of the frequency converter should be amplified by one step or the output reactor should be installed at the output of the frequency converter.

2) Purpose of frequency conversion; Constant voltage or current control, etc.

3) Load type of the frequency converter of the film blower; For example, blade pump or volume pump, pay special attention to the performance curve of the load, which determines the method of application.

4) When using the frequency converter to drive the high-speed motor, the output current value increases due to the small reactance of the high-speed motor and the increase of high-order harmonics. Therefore, the selection of frequency converter for high-speed motor has a slightly larger capacity than that of ordinary motor.

5) For some special applications, such as high temperature and high altitude, this will cause the capacity of the frequency converter to be reduced, and the capacity of the frequency converter should be enlarged one stop.

6) Matching between frequency converter and load of film blower;

I. Torque matching; This may occur when there is a constant torque load or a decelerator.

II. Voltage matching; The rated voltage of the frequency converter corresponds to the rated voltage of the load.

III. Current matching; For normal centrifugal pumps, the rated current of the frequency converter corresponds to that of the motor. For special loads such as deep water pumps, motor performance parameters are needed to determine the current and overload capacity of the frequency converter with the maximum current.
