Wu Wind turbine constant temperature system
The wind duct system complies with the "Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering" GB50243-2002 standard, and is usually composed of a circulation system, a heating system, and an over temperature exhaust system. The circulation system, over temperature exhaust system, heating system, and supporting air duct system are installed on the top or rear of the aging room, without occupying any other space. The circulation system uses circulation fans and supporting air ducts for circulation, ensuring uniform temperature in the testing area. The heating system uses electric heaters for heating, which are placed in the circulation air duct on the roof of the aging room and surrounded by fire-resistant and heat-insulating materials. Using PID instrument control and SSR temperature control, once the temperature reaches the required temperature for the product, the power of the heater is automatically adjusted according to the fluctuation of indoor temperature, in conjunction with the insulation properties of the insulation board, to accurately stabilize the indoor temperature at the set temperature value. The indoor temperature can be increased to the set temperature within the specified time, and the heater stops heating when the temperature rises to the set value The heater is equipped with an overheat protection device (EGO). If the customer's own product generates heat, an overheat exhaust system is used. If the heat generation is small, an electric louver automatic negative pressure exhaust is used. If the heat generation is large, a low-noise fan is used for exhaust.
Cycle temperature control process: When the heater starts heating and the temperature reaches the set value, the heater stops heating. As time goes by, the temperature in the product area will gradually rise. When the temperature exceeds the set upper limit, the exhaust system will start to operate and exhaust the overheated gas in the product area outside. The frequency converter will control the outdoor exhaust fan to operate. When the temperature drops to the lower limit of the set value, the fan will stop exhausting and the exhaust system will be turned off at the same time. The circulatory system maintains a cyclic state throughout the aging process of the product to ensure temperature balance. The entire system has the characteristics of stable performance, precise control, small temperature fluctuations, high balance, and low noise.
Noise treatment: High quality circulating fans with low decibels are used, and the air ducts are wrapped in 3mm thick asbestos, which not only provides insulation but also reduces noise. According to acoustic principles, all dynamic parts are treated with canvas and springs for soft joints, striving to reduce noise.
Aging room control system
By using two-stage PID+SSR to adjust the heating amount, accurate control of the temperature in the testing area (product area) is achieved. At the same time, the temperature controller can display any temperature in the testing area in real-time through rolling. For independent loads, the temperature in the load area can also be monitored to prevent excessive temperature in the load area, making it convenient for customers to accurately grasp the temperature situation in the testing area. The control system is also equipped with various protection functions, including over temperature alarm protection, fan fault alarm protection, no wind alarm protection, indoor smoke induction alarm protection, etc. The complete protection functions ensure that the aging room can operate stably and without faults for a long time. (Optional PLC for control)
Product testing rack (optional)
Product testing racks are usually designed and manufactured based on customer products and requirements. If a load is required, a corresponding load frame should be produced to match it. Generally, the design of the testing rack requires a stable and reasonable structure, easy operation, beautiful appearance, and functional requirements.
Lu Control system design and safety protection measures
6.1 The electrical control design shall refer to the "Code for Design of Low Voltage Distribution" GB50054-95, "Code for Design of Power Supply and Distribution" GB5002S2-95, and "Code for Construction and Acceptance of Grounding Devices in Electrical Equipment Installation Engineering" GB50169-92, in order to standardize the electrical control design.
6.2 Control system integration aging function design. Design a functional control cabinet, where the aging time, temperature, and various operation switches can be operated on one control cabinet; The panel design of the electrical cabinet is aesthetically pleasing and easy to operate.
6.3 The aging process can be fully controlled automatically, with some abnormal self handling functions, making the operation automated and simplified.
6.4 It has multiple protection functions and is safe and reliable.
a. Electric heating prevents dry burning. When the fan fails or the temperature inside the air duct is too high, the power supply of the circulation system will be automatically cut off, and the alarm will sound at the same time.
b. The design of electric heating and fan linkage means that the heater cannot be started separately when the fan fails to start. When turned off, both the electric heating and circulating fan are turned off to prevent damage to the electric heating due to dry burning.
c. The heater connection adopts high-temperature resistant wire, which does not burn at 300 degrees.
d. Install explosion-proof lighting indoors to extend the lifespan of light bulbs and prevent them from bursting.
e. The warehouse body adopts flame-retardant insulation materials with good insulation performance and high safety factor.
f. Overtemperature sound and light alarm function: In case of overheating during the aging process, the red light will turn on and the buzzer will sound.
g. Smoke alarm function: Indoor smoke detectors are installed to prevent the product from burning and triggering an alarm due to certain reasons during the aging process. When the alarm is triggered, the power supply of the aging room will be automatically turned off.
The determining factors of the cost of aging houses
Seven The price composition of aging houses is composed of the following factors
1: Room size (room size determines fan selection, number of fans, and duct size)
Usually, there are axial flow fans, centrifugal fans, and wind cabinets available on the market for production
Axial flow fans are installed on the aging roof, and corresponding louvers are installed on the ceiling according to the number of fans. The concept of upper air outlet and upper air return is adopted, which is low-cost and has low temperature uniformity controllability because the hot air flows from bottom to top
The centrifugal fan is installed on the aging roof, and the corresponding number of air ducts is designed according to the power of the fan and the size of the room. Each air duct is connected to the bottom of the room, and two double-layer louvered air outlets are installed on each air duct, which can adjust the direction of the air outlet. Then, the air is circulated through the top return air outlet. Generally, aging rooms that are not very large use centrifugal fans as the main fan.
Wind cabinets are mainly used in aging rooms where the room is too large, the span is too wide, and the temperature uniformity requirements are too high. If the room is too large, the number of centrifugal fans used will increase accordingly, and the noise will be very loud. The cost of this construction is very high,
2: Temperature range (different materials are selected for different temperature ranges)
The commonly used insulation material on the market currently is high-density rigid polyurethane foam. The exterior is made of color steel plate, which has a temperature resistance of 100 degrees, good hardness, and excellent quality. Especially for large-scale aging rooms, this material is often used, and it is easy to disassemble and assemble, making it convenient for the relocation of aging rooms. But the price is relatively expensive, but most professional companies will use it.
3: Products that require aging and product power (the difference in products depends on whether they generate heat, and power depends on the configuration of the power supply inside)
The power of aging products: In the aging room, the aging rack of the product needs to be powered, and the power depends on the size and quantity of the wires.
4: Temperature uniformity requirements
The temperature in the aging room is generally ± 1 ℃ at 40 degrees Celsius, ± 3 ℃ at 50 degrees Celsius, and ± 5 ℃ above 60 degrees Celsius. If the uniformity requirement above 60 degrees Celsius is too high, PLC can be used for multi-point control or controlled by a mother child machine.
5: The temperature point for aging and the total power of the product (involving the exhaust system, the exhaust is determined by the room size, temperature range, and product power to maintain a constant temperature point. When the product heats up too high, the exhaust fan runs to ensure that the temperature is controlled at the set temperature)
The common temperature points for aging rooms involve the exhaust system. Based on the total power (heating power) of the products in the aging room and the required temperature, the power of the exhaust fan and the size of the exhaust duct are calculated using corresponding formulas. The current technology on the market is hot air circulation, which has good temperature uniformity.
