What are the advantages and disadvantages of using hydraulic drive in injection molding machine?
The advantages of hydraulic transmission in injection molding machine are as follows.
Low speed and high torque hydraulic motor can be used to drive a mechanism directly.
Potassium drive works smoothly, so it is not easy to generate impact when moving, and can be changed frequently
Torque stepless speed control, large range of speed control.
In case of overload, safety protection is provided.
Under the same working condition of the same power, the hydraulic drive structure is compact and the equipment volume is relatively small.
The working parts in the methanfluid system are well lubricated and have a long service life.
Using the combination of electricity and liquid to coordinate the work, we can get more complex automatic program control and cycle work.
Parts and components used in hydraulic drive can be made universal, standardized and serialized, which can reduce the manufacturing cost of hydraulic drive equipment.It provides a convenient condition for the maintenance and replacement of worn parts of the hydraulic drive system.
The disadvantages of hydraulic transmission are as follows
The pipe line in hydraulic drive is easy to leak out.
Parliamentary hydraulic transmission ratio is not accurate enough.
The temperature change of hydraulic fluid in the torque hydraulic drive will affect the stability of the drive.
The vibration and noise of transmission work will be produced when air is mixed into hydraulic oil.
Correspondingly, the manufacturing precision of working parts in hydraulic transmission is high.
In case of failure in the hydraulic transmission system, the maintenance work is relatively complex, requiring a highly skilled maintenance technician to repair the equipment.
