Target Users: Engineering companies engaged in clean engineering, medical engineering, construction engineering, laboratory engineering, laboratory equipment, medical devices, medical equipment, environmental protection technology, environmental science and technology, biotechnology, etc.
The vertical laminar flow clean bench is a crucial piece of equipment in various industries where a high level of cleanliness is required. It provides a localized clean environment, ensuring that operations such as experiments, manufacturing, and research are carried out without contamination. Below is a detailed introduction to this essential equipment.
一、What is a Vertical Laminar Flow Clean Bench?
A vertical laminar flow clean bench is an air purification device that delivers a local high - cleanliness working environment. Its working principle is as follows: the fan draws in external air, which then passes through a primary filter and a high - efficiency filter. After filtration, the air is uniformly sent into the working area in the form of vertical laminar flow, thereby creating a clean and sterile operating space in the work zone.
This equipment is widely used in fields such as biological laboratories, electronic manufacturing, medical and health care, and food processing. In biological laboratories, it provides a sterile environment for experiments like microbial culture and cell manipulation, effectively preventing experimental samples from being contaminated. In the electronic manufacturing industry, it can prevent impurities such as dust from damaging precision electronic components, ensuring product quality. In the medical and health field, it can be used in links such as drug preparation and packaging to ensure the cleanliness of drugs.
二、Advantages and Disadvantages of Vertical Laminar Flow Clean Bench
Advantages:
1. High cleanliness: The vertical laminar airflow can effectively prevent external pollutants from entering the work area, maintaining a high level of cleanliness in the work zone, generally reaching class 100 cleanliness.
2. Convenient operation: The work area has a relatively spacious space, allowing operators to perform various operations more conveniently with a wide field of vision.
3. Good safety: For some operations with biological hazards, the vertical flow design can reduce the risk of harmful gases or microorganisms spreading outward, protecting the safety of operators.
Disadvantage:
1. High energy consumption: To maintain stable vertical laminar flow and cleanliness, the equipment needs to continuously operate components such as fans, resulting in relatively high energy consumption.
2. High maintenance cost: The high - efficiency filter needs to be replaced regularly; otherwise, the filtering effect will be affected. The cost of the high - efficiency filter is relatively high, increasing the maintenance cost of the equipment.
3. Certain restrictions on environmental requirements: The environmental conditions around the equipment will affect its working effect. If there is too much dust in the surrounding environment, the service life of the filter will be shortened.
三、Wind Speed Measurement and How to Measure in Vertical Laminar Flow Clean Bench
Wind speed is one of the important indicators to measure the performance of a vertical laminar flow clean bench. An appropriate wind speed can ensure the cleanliness and stability of the work area. If the wind speed is too low, it cannot effectively prevent external pollution from entering; if the wind speed is too high, it may cause turbulence in the air flow in the work area, affecting operations and increasing energy consumption.
For measuring the wind speed of a vertical laminar flow clean bench, a hot - bulb anemometer or a digital anemometer is usually used. The measurement method is as follows:
1. Before measurement, ensure that the equipment has been operating normally for at least 30 minutes to stabilize the air flow in the work area.
2. Divide the workbench surface into several uniform measuring points, generally in a grid of 50mm×50mm.
3. Hold the anemometer, place the sensor at the height of each measuring point (usually 100 - 150mm above the workbench surface), keep the anemometer horizontal, and record the value after the reading stabilizes.
4. After the measurement is completed, calculate the average wind speed of all measuring points, which should comply with the specified wind speed range of the equipment (generally 0.25 - 0.5m/s).
四、Precautions for Using the Clean Bench
1. Before operation, clean and disinfect the work area. Wipe the workbench surface and inner walls with 75% alcohol to avoid residual pollutants affecting experiments or production.
2. Operators should wear clean work clothes, masks, gloves and other protective equipment to reduce pollution from themselves.
3. Items placed in the work area should try to avoid blocking the air flow, and there should be a certain gap between items to ensure the smooth flow of air.
4. During operation, do not put your head into the work area to avoid polluting the working environment with exhaled gas.
5. When the equipment is running, do not open the front window of the work area too high, so as not to destroy the laminar flow state and affect the cleanliness.
6. Regularly maintain the equipment, including checking the operation status of the fan and the resistance of the filter. When the filter resistance exceeds the specified value, it should be replaced in time.
7. After the equipment is stopped, turn off the power of the fan and other components, clean the equipment, and record the usage of the equipment.
The vertical laminar flow clean bench, as an important clean equipment, is indispensable in clean production and experiments in various industries. Understanding its relevant knowledge, using and maintaining it correctly, can give full play to its performance and provide a reliable clean environment for production and experiments.
