Frequently Asked Questions (FAQ)
What is the vacuum flow of the ZH20-B-X185?
The vacuum flow of the ZH20-B-X185 can reach up to 3 times the supply air flow, making it highly efficient for vacuum suction tasks. This high-flow feature performs exceptionally well in handling granules, powders, and other materials. Users can adjust the supply pressure according to their needs to optimize vacuum flow.
Does the ZH20-B-X185 require regular maintenance?
The ZH20-B-X185 requires no regular maintenance, offering an advantage over electric blowers. With no moving parts, the air vacuum generator reduces the risk of failure and lowers maintenance costs. Users only need to regularly inspect the air supply pipe and filter to ensure no blockages or leaks.
What are the application scenarios for the ZH20-B-X185?
This device is widely used in blowing and vacuum tasks, such as removing water droplets, blowing away chips, and welding fume extraction. It is suitable for industrial automation, robotic handling systems, material handling, and other fields. Its large flow rate and passage diameter enable it to handle chips, dust, and other impurities.
How to adjust the blowing and vacuum flow?
Users can control the blowing or vacuum flow by adjusting the nozzle position. Turning the nozzle counterclockwise increases the flow (vacuum pressure increases), while turning it clockwise decreases the flow (vacuum pressure decreases). Adjust according to the actual application needs.
What are the installation options for the device?
The ZH20-B-X185 is equipped with a mounting bracket for easy integration into existing systems. Users can choose the installation location based on the equipment layout to ensure the vacuum generator is securely fixed.
What should be noted about the exhaust port of the device?
The exhaust port may expel dust and impurities, so it should not be directed towards personnel or sensitive components. When designing the system, ensure the safety of the exhaust port to avoid hazards to operators.
Is the device suitable for high-humidity environments?
The ZH20-B-X185 can operate in environments with temperatures ranging from -5°C to 80°C (non-freezing). However, in high-humidity environments, precautions should be taken to prevent condensation of water vapor, which may affect vacuum generator performance.
What is the energy consumption of the device?
The ZH20-B-X185 uses an efficient air amplification principle to increase the blowing flow to up to 4 times the supply air flow. This design significantly reduces compressed air consumption and saves energy. Users can further optimize energy consumption by adjusting the supply pressure according to their needs.
What is the noise level of the device?
The ZH20-B-X185 operates at low noise levels, making it suitable for noise-sensitive environments. Its design without moving parts further reduces operational noise. Users can choose an appropriate installation location to minimize the impact of noise on the working environment.
Does the device support dust-proof functionality?
The ZH20-B-X185 can be equipped with a dust-proof bag assembly (e.g., ZH-DB1-20-A) to prevent dust from entering the SMC vacuum ejector. When handling large amounts of dust or impurities, it is recommended to add a larger filter. Dust-proof measures help extend the device's lifespan and ensure stable performance.
