Selection Method of Drying Oven Fan

Drying oven fan selection is a very technical work, and there are many specific selection methods, such as: according to the dimensionless characteristic curve selection, according to the logarithmic coordinate curve selection, according to the dimensional characteristic curve or performance table selection, variant selection, according to the pipe network resistance selection, etc. At present, there is also a Web selection system and the use of special selection software to select. Methods are numerous and complex, and some methods require certain professional knowledge to master.

When choosing a fan, first according to the two basic parameters of the air volume and total pressure of the fan, the model and number of the fan can be determined through the dimensional performance table of the fan (each fan product manual has relevant data), and more than one product may meet the requirements; At this time, combined with the use of the fan, process requirements, use occasions, etc., select the type, model and structural material of the fan to meet the required working conditions, and strive to make the rated flow rate and rated pressure of the fan as close as possible to the flow and pressure required by the process, so that the operating condition point of the fan is close to the efficient area of the fan characteristics.

The specific principles of the drying oven are as follows:

1, Before choosing the fan, we should understand the production and product quality of the domestic ventilation phase, such as the production of fan varieties, specifications and special uses of various products, the development and promotion of new products, etc., should also fully consider the requirements in order to choose the best fan.

2, According to the different physical and chemical properties of the gas transported by the fan, choose different uses of the fan. Explosion-proof ventilator should be selected if there are explosive and flammable gases; Dust or pulverized coal should be selected to exhaust dust or pulverized coal fan; Conveying corrosive gases should choose anti-corrosion fan; Working in high temperature occasions or conveying high temperature gas should choose high temperature fan.

3, When there are more than two kinds of fans to choose from on the fan selection performance chart, the higher efficiency and smaller machine number should be preferred; One with a larger range of adjustment, of course, should also be compared and decided by weighing the advantages and disadvantages.

4, If the selected fan impeller diameter is much larger than the original fan impeller diameter, in order to use the original motor shaft, bearing and support, it is necessary to calculate the motor starting time, the strength of the original fan components and the critical speed of the shaft.

5, Choose the centrifugal fan, when the motor power is less than or equal to 75KW, can not be installed only for the start of the valve. When high temperature flue gas or air is discharged and the centrifugal boiler induced draft fan is selected, a starting valve should be set up to prevent overload during cold operation.

6, For the ventilation system with noise reduction requirements, the ventilator with high efficiency and low impeller circular speed should be selected first, and the ventilator should work at the high efficiency point; According to the transmission mode of noise and vibration generated by the ventilation system, corresponding measures should be taken to reduce sound and vibration. Vibration reduction measures for fans and motors can generally use vibration reduction bases, such as spring shock absorbers or rubber shock absorbers.

7, In the selection of fans, should try to avoid the use of fans in parallel or series work. When unavoidable, the ventilator of the same model and performance should be selected for joint work. When the series is used, there should be a certain pipeline connection between the stage ventilator and the second stage ventilator.

8, The selected new fan should consider making full use of the original equipment, suitable for on-site production and installation and safe operation.

Technical Characteristics of Refrigeration and Temperature Control System of High and Low Temperature Test Chamber

High and low temperature test chamber is a kind of test equipment widely used in various industries, which is widely used to simulate various environmental conditions and test the durability, reliability and corrosion resistance of products. The technical characteristics of the high and low temperature test chamber are mainly reflected in its refrigeration system and temperature control system.

First of all, the refrigeration system of the high and low temperature test chamber has a high refrigeration capacity and refrigeration speed. During the temperature control process, a refrigeration system is needed to quickly reduce the temperature inside the test chamber. At present, the mainstream refrigeration system mainly has two kinds of compression refrigeration system and refrigerant loop circulation system. Among them, the compression refrigeration system has a high refrigeration capacity and refrigeration speed, which can quickly reduce the temperature inside the test chamber to the set temperature, but also to ensure the stability of the temperature.

Secondly, the temperature control system of the high and low temperature test chamber has high accuracy and stability. The temperature control system is the core part of the whole test chamber, which realizes the accurate control and stability maintenance of the internal temperature of the test chamber through the adjustment and control of the refrigeration system and the heating system.

High and low temperature test chamber usually adopts temperature control system to achieve accurate temperature control. The system consists of temperature sensors, controllers and heaters. The temperature sensor is placed inside the test chamber to monitor the temperature change in real time, and the controller automatically controls the output power of the heater according to the signal of the sensor to achieve the purpose of accurate temperature control.

2, Temperature fluctuation control

Temperature fluctuation is an important index of accurate temperature control in high and low temperature test chamber. In order to ensure the stability of the temperature inside the test chamber, the controller will reduce the temperature fluctuation by adjusting the output power of the heater. Under normal circumstances, the accuracy of temperature fluctuations is required to be within 0.2°C.

3, Sealing control

The tightness of the high and low temperature test chamber is one of the important factors to ensure accurate temperature control. The tightness of the test chamber needs to be ensured by strict airtight testing to ensure that the heat inside the test chamber does not leak to the outside, or the heat from the outside does not enter the inside.

4, Time control

The time control of high and low temperature test chamber is also an important means to ensure accurate temperature control. The controller can set the test time according to the test needs, and automatically stop the test after the test time arrives to ensure the safety of the test sample.

In summary, the accurate temperature control of the high and low temperature test chamber is achieved through the joint action of many factors such as temperature control system, temperature fluctuation control, sealing control and time control.

Use Principle of High and Low Temperature Test Chamber Low Temperature and Constant Temperature Tank 

Because of its own circulation system, the uniformity of temperature field is very high, and more and more experiments are applied to the low temperature constant temperature tank. Mainly used in petroleum, chemical, electronic instrumentation, physics, chemistry, biological engineering, medicine and health, life science, light industrial food, physical property testing and chemical analysis and other research departments, colleges and universities, enterprise quality inspection and production departments, to provide users with a hot and cold controlled, uniform and constant temperature field source for test samples or products to perform constant temperature test or test. It can also be used as a heat source or cold source for direct heating or cooling and auxiliary heating or cooling.

What are the precautions for using a low temperature or constant temperature tank?

1, Before the use of low temperature constant temperature tank, the tank should be added to the liquid medium (pure water, alcohol, methyl silicone oil), the medium liquid level should be less than 20mm workbench, otherwise the power will damage the heater.

2, The selection of liquid medium in the low temperature constant temperature tank should comply with the following principles:

When the operating temperature is below 5 ° C, the liquid medium is generally alcohol;

When the operating temperature is 5 ~ 85℃, the liquid medium is generally water;

When the working temperature is 85 ~ 95℃, the liquid medium can choose 15% glycerol aqueous solution, which can reduce the evaporation of water;

When the operating temperature is higher than 95 ° C, oil is generally selected as the liquid medium, and the open cup flash point value of the selected oil should be higher than the operating temperature of 50 ° C or more; Generally, methyl silicone oil with low viscosity is used.

3, Power supply: 220V50Hz, the power supply should be greater than the total power of the instrument, the power supply must have a good "grounding" device.

4, The instrument should be placed in a dry and ventilated place, and there are no obstacles within 300mm around the instrument.

5, When the thermostat working temperature is high, should be careful not to open the cover, hands do not enter the groove, to prevent hot injury.

6, After using, all switches are placed in the off state, cut off the power.

7, Avoid acid and alkali substances into the tank corrosion coil and inner liner.

8, The instrument should do a good job of regular cleaning work, long-term use, empty the media in the tank, and wipe clean, keep the workbench and the operating panel clean.

9, Often pay attention to observe the liquid level in the tank, when the liquid level is too low, the liquid medium should be added in time.

10, Liquid external circulation, customers should pay special attention to the fastness of the connection of the leading pipe, strictly prevent falling off, so as to avoid liquid leakage.

What are the Types of PCB Environmental Tests?

High acceleration test:

Accelerated tests include high accelerated life test (HALT) and High accelerated Stress screening (HASS). These tests assess the reliability of products in controlled environments, including high temperature, high humidity, and vibration/shock tests when the equipment is powered on. The goal is to simulate the conditions that could lead to the imminent failure of a new product. During testing, the product is monitored in a simulated environment. Environmental testing of electronic products usually involves testing in a small environmental chamber.

Humidity and corrosion:

Many PCBS will be deployed in wet environments, so a common test for PCB reliability is a water absorption test. In this type of test, the PCB is weighed before and after being placed in a humidity controlled environmental chamber. Any water adsorbent on the board will increase the weight of the board, and any significant change in weight will result in disqualification.

When performing these tests during operation, exposed conductors should not be corroded in a humid environment. Copper oxidizes easily when it reaches a certain potential, which is why exposed copper is often plated with an antioxidant alloy. Some examples include ENIG, ENIPIG, HASL, nickel gold, and nickel.

Thermal shock and circulation:

Heat testing is usually performed separately from humidity testing. These tests include repeatedly changing the board temperature and checking how thermal expansion/contraction affects reliability. In thermal shock testing, the circuit board uses a two-chamber system to quickly move between two temperature extremes. The low temperature is usually below the freezing point, and the high temperature is usually higher than the glass transition temperature of the substrate (above ~130 ° C). The thermal cycle is carried out using a single chamber, with the temperature changing from one extreme to the other at a rate of 10°C per minute.

In both tests, the board expands or contracts as the board temperature changes. During the expansion process, conductors and solder joints are subjected to high stress, which speeds up the service life of the product and enables the identification of mechanical failure points.

This article will provide a detailed comparative analysis of the significant advantages of our AI vision inspection technology in defect detection.

I. Traditional Defect Detection Methods in Block Bottom Valve Bag Making Machines

In traditional block bottom valve bag machines, many devices use a scrap removal mechanism based on sensors and labels. For example, European brands such as Strarlinger and W&H typically require manual labeling of bags during the production process. The bags are marked with specific labels, and the sensors then detect the presence of these labels to identify defective bags. The working principle of this method is as follows:

Manual Labeling: Before production, operators need to manually mark each batch of bags, usually by applying specific colored, shaped, or patterned labels.

Sensor Recognition: The bagging machine is equipped with sensors that scan the label positions to check for defects. When the sensor detects a missing or mispositioned label, the machine automatically discards the defective bags.

Frequent Human Intervention: The entire process relies heavily on the accuracy and consistency of the manually applied labels. Any errors in labeling may result in inaccurate defect identification, affecting both production efficiency and product quality.

While this traditional detection method is simple, it has notable drawbacks, particularly in terms of detection precision, human involvement, and production efficiency.

This eliminates the need for manual involvement and significantly reduces human errors and operational complexity.

• Lower Labor Costs: Since the AI vision system automatically performs inspection tasks, it reduces the labor intensity and costs associated with manual operations.

• Improved Production Efficiency: Automation in defect detection means the time spent on inspection within each production cycle is significantly reduced, enhancing overall production efficiency and minimizing downtime.

3. Multi-dimensional Detection Capabilities, Covering More Defects AI vision inspection technology offers comprehensive, multi-dimensional defect detection for various stages of the bag making process, including fabric roll defects, printing defects, and bag shape defects. This extensive coverage is unmatched by traditional label-based detection systems.

•  Fabric Roll Defect Detection: High-speed cameras quickly capture fabric roll defects such as tears, holes, seams, and stains, with no need for manual intervention.

• Bag Making Process Defect Detection: During the bag forming process, the AI vision system can promptly detect issues such as shape deviations, bottom patch misalignment during heat sealing, folds, and uneven openings.

• Printing Defect Detection: For printing quality, the AI vision system can accurately detect printing misalignment, defects, and other issues, ensuring that every bag meets high-quality standards.

4. Real-time Feedback and Adjustment, Optimizing the Production Process AI vision inspection systems not only detect defects efficiently but also provide real-time feedback, offering dynamic suggestions for adjustments to the block bottom valve bag making machine's production process. For example, when a particular defect occurs frequently, the system can issue an alert to inform operators to inspect the equipment or adjust production parameters, thereby preventing large-scale defective products from being produced.

•  Real-time Data Feedback: Defect data from each production stage is fed back to the system, providing detailed reports on the production status.

•  Optimized Production Decisions: Based on real-time feedback, operators can make timely adjustments during the production process, further optimizing production efficiency and product quality.

5. Intelligent Learning and Self-Optimization In addition to performing inspection tasks, AI vision inspection systems have the ability to learn and optimize themselves. As the system is used over time, the AI algorithms continuously adjust and improve based on real production data, enhancing detection accuracy and efficiency.

• Deep Learning Algorithms: The AI system constantly improves its defect recognition capabilities through deep learning, becoming more accurate as production data accumulates.

• High Adaptability: Whether it's changes in fabric types or adjustments in production processes, the AI vision system can quickly adapt and maintain high operational efficiency.
