With the rapid development of science and technology, vacuum generators have gradually become an indispensable key equipment in modern industry. Vacuum generator, also known as vacuum pump, is mainly used to create a vacuum environment in equipment and process. The function of a vacuum generator is to extract gas and air from within the system, creating a vacuum. Vacuum ejectors are widely used in various industries and bring many important advantages and benefits. This article will introduce some of the main advantages of vacuum generators and their applications in industry.Firstly, vacuum generators play a crucial role in industrial production. They are widely used in various mechanical manufacturing and processing processes, especially in high-tech fields and the semiconductor industry. A vacuum generator creates a low-pressure, low-temperature, and low-energy state by extract...

Compressed air enters from the inlet of the single-stage vacuum generator and flows through the Venturi nozzle. As the cross-section gradually decreases, the pressure of the compressed air increases and the flow rate also increases At this point, a vacuum degree is generated at the inlet of the adsorption chamber, causing the surrounding air to be sucked into the vacuum generator and flow into the diffusion chamber along with the compressed air to increase the gas flow rate. Finally, it is sprayed out through the muffler In addition to a single-stage vacuum generator, there is also a vacuum generator that arranges several Venturi tubes in sequence together, called a multi-stage vacuum generator, which can generate much greater suction force than a single-stage vacuum generator Compressed air enters the multi-stage vacuum generator from the inlet and passes through multiple Ventu...

vacuum generatorIt is a device that generates vacuum through compressed air and is widely used in fields such as adsorption and transportation. However, in actual use, there may sometimes be insufficient suction, which affects the normal operation of the equipment. The following are common reasons and solutions for low suction force in vacuum generators.1. Insufficient supply of compressed air• Reason: The vacuum generator relies on compressed air drive. If the supply pressure or flow rate is insufficient, it will directly lead to a decrease in vacuum degree and a weakening of suction force.• Solution: *Check the gas supply system to ensure that the pressure meets the requirements of the vacuum generator (usually 4-6 bar).*Clean the gas supply pipeline to avoid blockage or leakage.2. Vacuum pipeline leakage• Reason:There is air leakage in the ...
