What is Pneumatic Vacuum Loading Machine?

Pneumatic Vacuum Loading Machine is a new material conveying equipment driven by compressed air. It is different from traditional electric vacuum pump models. It does not require additional motors, reduces the size and noise of the equipment from the root, adapts to powders, particles and other materials, and has customized options such as explosion-proof and anti-static. The characteristic of no power drive is especially suitable for chemical explosion-proof workshops, temporary work stations without power supply, etc., providing flexible and safe solutions for material transfer on the production line.

What are the advantages of Pneumatic Vacuum Loading Machine?

The pneumatic vacuum feeder is powered by compressed air, does not require a motor, has strong explosion-proofness, simple structure, easy maintenance, and no motor maintenance cost; it is fully airtightly conveyed, meets the clean standards, and can also flexibly deal with temporary stations.

Convenient power: Powered by conventional compressed air in the factory, there is no need to install an additional electric vacuum pump to avoid the problem of motor land occupation and wiring. It is especially suitable for chemical explosion-proof workshops and no temporary power supply stations.

Low noise energy saving: high-frequency noise generated by motor operation, low working noise, and no maintenance needs such as motor wear and lubricant replacement.

Clean and oil-free: The vacuum generator is free of oil and dirty production, and it is matched with stainless steel contact material parts and coated filter element. After the gas material is separated, the air is clean and free of impurities, meeting the food and pharmaceutical industries and other clean standards.

Small size: without motors and large pumps, the volume of the entire machine is 40% smaller than that of the motor model with the same production capacity. It can be installed on wall or brackets, and is suitable for narrow space in the workshop.

How does Pneumatic Vacuum Loading Machine work?

The core of the pneumatic vacuum feeder uses compressed air as the power source, and the pressure energy of compressed air is converted into negative pressure energy through the vacuum generator: the compressed air enters the nozzle of the vacuum generator and is sprayed at high speed, taking away the air in the generator cavity, so that a stable negative pressure is formed in the connected conveying system. At this time, the external atmospheric pressure forms a pressure difference between the system negative pressure, and the material is sucked into the conveying pipeline from the suction port and enters the separation hopper with the airflow; in the hopper, the gas mixture is filtered through a high-efficiency filter element, and the material falls into the target equipment due to gravity. The filtered clean air merges with the exhaust gas discharged from the vacuum generator and is discharged from the exhaust port.

What are the main structures of Pneumatic Vacuum Loading Machine?

The pneumatic vacuum feeding machine is mainly composed of a vacuum generator, suction component, separation hopper, discharge valve and control system. Each component coordinates to achieve the separation of negative pressure suction and gas.

Power core: Vacuum generator: Using compressed air as the driving source, high-speed air flow is injected through the internal nozzle, the air in the system is discharged to form a stable negative pressure, and is usually directly connected to the compressed air pipeline.

Material conveying assembly: includes suction port and conveying pipeline. The suction port has many sealing rings to ensure sealing; the conveying pipelines are mostly made of stainless steel, and different diameters are selected according to the conveying distance and material characteristics.

Gas material separation unit: separation hopper: As the core for the temporary storage of materials and the separation of gas materials, it is equipped with a high-efficiency filter element inside to intercept materials and allow air to pass through. The bottom of the hopper is usually equipped with unloading.

Control components: consist of a pneumatic control box and sensor. The pneumatic control box adjusts the compressed air pressure and controls the start and stop of the vacuum generator; the pressure sensor monitors the negative pressure of the system, and the material level sensor senses the height of the material in the hopper to ensure the automatic start and stop and circulating operation of the equipment.

Pneumatic Vacuum Loading Machine vs Electric Vacuum Loading Machine

How to judge whether the working pressure of Pneumatic Vacuum Loading Machine is normal?

To determine whether the working pressure of Pneumatic Vacuum Loading Machine is normal, you can use the three steps of "seeing the instrument, observing the operation, and checking the status".

Look at the vacuum pressure gauge value: The vacuum pressure gauge standard equipped with the equipment will display the negative pressure value in real time. You can refer to the equipment manual. If the value is below the lower limit for a long time, it may be that the seal leaks or the filter element is blocked; if it is higher than the upper limit, it may be that the vacuum generator is faulty or the intake pressure is too high, and it needs to be adjusted in time.

Observe the material conveying status: When the pressure is normal, the material is sucked in at a constant speed from the suction port, and there is no obvious blockage or stuttering in the pipeline, and the hopper is discharged smoothly during unloading; if the material is slow to absorb and cannot be suctioned, it is mostly insufficient negative pressure; if the material is violently impacted and the noise becomes large in the pipeline, it may be that the negative pressure is too high, causing the air flow to be too fast.

Check the equipment seal and exhaust: Check whether the suction port seal ring and pipe interface are damaged and leaked, and observe the exhaust port at the same time. In normal times, there is no dust or abnormal airflow sound. If the exhaust gas is loaded with materials or sounds harsh, it may be caused by abnormal pressure to cause the filter element to fail or the air circuit failure.
