The vacuum charger is mostly vacuum-absorbing, and the working principle of vacuum delivery is to form a certain negative pressure in the hopper cavity to inhale the material. The process of automatic vacuum conveyor is: a negative pressure generated by a vacuum generator or a Roots pump.
When the closed system reaches a certain vacuum, the suction is started. After the suction is completed, it is discharged to the hopper, and the material is released After a certain preparation time, the next loop process is carried out. In this reciprocating process, the material can always meet the equipment of the equipment.
Usage and precautions for vacuum machine: Material particles and shape, material delivery distance and material delivery height, material feed position, material density and material fluidity, etc., material sensitivity, material compatibility, conveying pipe The amount of bending, energy consumption, material toxicity, and flammable explosive.
How is the brake tension of the vacuum machine control? Long-distance big ship tape upper machine due to high power, long distance and multi-machine drive, must use soft starting mode to reduce the tension of the upper mechanism, especially Multi-motor drive. In order to reduce the impact on the grid, there should be a slow start when the soft start is slow; also controls the upper air start acceleration of 0.3 to 0.1 m / s2. Solve the speed synchronization problem of the bearer belt and the drive belt and the conveyor stroke, and reduce the impact of the components.
Due to manufacturing errors and motor characteristics, the power of each drive point occurs unbalanced. Once a motor power will cause a burnt motor accident, the power balance between each motor should be controlled, and the balance accuracy is improved.
Domestic have been applied to the speed of the upper motor and the soft start and power balance of the upper. The start and power balance and synchronization problems of long-range tape upper machines are solved. However, its adjustment accuracy and reliability have a certain gap compared to foreign countries.
Welcome to Shandong AlPa Powder Technology Co., Ltd., above the principle of vacuum charger delivery.
