1、 Main functions of the device:

The Wind pressure testing machine is used to determine whether the equipment can maintain structural integrity and work in high wind speed environments. It is mainly suitable for evaluating equipment working outdoors in mountainous, coastal, island, and other areas, as well as equipment placed on the open deck of ships for work.

2、 Performance indicators and system composition of wind pressure testing machine:

Model GC-FY-80

Sample restrictions: This testing equipment prohibits the testing of flammable, explosive, and volatile substance samples; Testing for storing samples of corrosive substances, testing for storing organisms, testing and storing samples of strong electromagnetic emission sources

Main technical parameters

Environmental conditions for use: ambient temperature of 5-35 ℃, relative humidity ≤ 85% RH

Blow off cross-sectional area 1000mm × 1000mm (fan outlet cross-sectional area)

Wind speed (0-45) m/s (wind speed at the outlet of the fan) adjustable

Air volume: 110600-181800m3/h (1843-3030m3/min)

Wind pressure 951-1402 Pa

Maximum specimen size ≥ 2000mm × 2000mm

The external dimensions of the machine are approximately 4200 × 3700 × 1500mm (W * H * D)

Sample Placement Room

To avoid the influence of surrounding air flow on the wind direction, the sample is placed in a closed room and the laboratory is sufficiently large. The horizontal dimension is at least 3 times the length of the sample placement, and the vertical and vertical dimensions are at least 2 times the length of the sample placement. An automatic pressure relief device or exhaust duct is also installed indoors

Test meets the conditions GJB150.21A-2009 Military Equipment Laboratory Environmental Test Methods Part 21: Wind Pressure Test

GB/T2423.41-94 Basic Environmental testing procedures for electrical and electronic products: Wind pressure test method

Maximum power 75KW

Maximum current of 120A

Power supply conditions

And power supply

AC 380V three-phase four wire+protective grounding; The allowable voltage fluctuation range is 10% V;

The allowable frequency fluctuation range is 50 ± 0.5HZ; TN-S power supply or TT power supply

The grounding resistance of the protective grounding wire is less than 4 Ω

Require users to configure corresponding capacity air or power switches for the equipment at the installation site, and this switch must be independently controlled. When placing powered samples in the equipment use box, please use an external power source for the sample power supply and do not directly use the local power supply;

The machine structure adopts a volute centrifugal fan as the power source

The snail shell is made as an assembled type, with a rotating air outlet angle that can be adjusted by ± 90o

Install a lifting frame at the bottom of the fan, which can be raised and lowered vertically with an adjustable range of 0-1000mm

Electrical control system

Centrifugal blower as power source, easy to use and maintain

The speed control of the fan adopts a frequency converter and a variable frequency motor to control the motor speed, achieving the purpose of controlling the wind speed

Requirements for storage, transportation environment, and installation site

Storage environment requirements: The equipment environment temperature should be maintained within 0 ℃ to+35 ℃

The installation site requires that the distance between the left, right, and rear wall panels of the test box and the wall should not be less than 800mm, and the distance between the front and the wall should not be less than 1000mm. When transporting equipment, whether it is possible to enter the entrance or passage, elevator, etc., to avoid affecting the progress of your company's project.

Transportation method: Whole machine transportation
