Unveiling the Working Principles and Applications of Industrial Vacuum Generators

Introduction to Industrial Vacuum Generators

An industrial vacuum generator is a new, efficient, clean, economical, and compact vacuum component that uses a positive pressure air source to generate negative pressure. This makes it very easy and convenient to obtain negative pressure where there is compressed air, or in a pneumatic system where both positive and negative pressures are required. Industrial vacuum generators are widely used in fields such as machinery, electronics, packaging, printing, plastics, and robotics in industrial automation.

Working Principle of Vacuum Generators

Industrial vacuum generators use a nozzle to jet air at high speed, producing an entrainment effect. This entrainment effect continuously sucks away the air around the nozzle outlet, causing the pressure in the suction chamber to drop below atmospheric pressure, forming negative pressure. This negative pressure acts like an invisible "hand," easily sucking and transporting various materials.

Types of Vacuum Generators

Generally speaking, industrial vacuum generators are divided into the following types:

Ordinary vacuum generator

It has an intake port, an exhaust port, and a vacuum port, which are used to connect compressed air, discharge exhaust gas, and generate negative pressure, respectively.

Vacuum generator with ejector switch

This type of vacuum generator has an additional ejector switch that can control the on-off of compressed air, making it easy to achieve vacuum suction and release.

Combined vacuum generator

Vacuum generators are often combined with solenoid valves, vacuum switches, check valves, and other vacuum components to meet specific performance requirements and facilitate installation.

Features of Vacuum Generators

Efficient

Industrial vacuum generators can efficiently use compressed air to generate negative pressure, achieving fast and stable vacuum suction.

Clean

As there is no need to use auxiliary materials such as lubricating oil, industrial vacuum generators do not produce pollution during operation, complying with environmental protection requirements.

Economical

Industrial vacuum generators have a simple structure, low manufacturing cost, and are easy to maintain, reducing the cost of use.

Compact

Industrial vacuum generators are small in size and lightweight, making them easy to carry and install, suitable for various narrow spaces.

Application Fields of Vacuum Generators

Industrial vacuum generators are widely used in machinery, electronics, packaging, printing, plastics, and robotics in industrial automation. Their conventional use is to work with suction cups for sucking and transporting various materials, especially suitable for sucking fragile, soft, thin non-ferrous, non-metallic materials, or spherical objects.
